The most dangerous part of a sewer backup isn’t the visible mess or the unpleasant smell. It’s the invisible threat left behind long after the water is gone. The black water that floods your home is a toxic soup of bacteria, viruses, and other pathogens that can cause serious illness. Simply removing the water and wiping things down isn’t enough to make your home safe again. A proper sewer backup cleanup requires a meticulous, multi-step process of cleaning, sanitizing, and drying to eliminate these hidden dangers and prevent long-term problems like mold. This guide will show you how to make your home not just look clean, but be truly safe for your family.
Key Takeaways
- Prioritize safety over cleanup: Before you do anything, make sure the area is safe. Shut off utilities (only if you can do so without walking through water), keep family and pets away, and wear full protective gear like waterproof boots, gloves, and a mask.
- Sanitize correctly and know what to toss: Removing the water is just the first step. You must wash and then disinfect all hard surfaces. Be prepared to throw away any porous items like carpets, mattresses, and upholstered furniture, as they cannot be made safe again.
- Focus on prevention to avoid a repeat: Once the crisis is over, take steps to stop it from happening again. Schedule annual plumbing inspections to clear clogs and consider installing a backflow preventer to protect your home from issues in the main sewer line.
What Is a Sewer Backup?
A sewer backup is one of the most stressful and unpleasant problems a homeowner can face. In simple terms, it’s when wastewater from the main sewer line flows backward into your home instead of away from it. This isn’t just water; it’s raw sewage, full of bacteria, viruses, and other contaminants. When this dirty water comes up through your floor drains, toilets, and sinks, it creates a serious health hazard and can cause extensive, costly damage to your property.
It’s important to understand the difference between a simple clog and a main line backup. If only one sink or toilet is blocked, the issue is likely isolated to that specific fixture. However, if you notice water backing up in multiple drains, especially on the lowest level of your home, you’re probably dealing with a main sewer line problem. This is more than a simple DIY fix; it’s a true plumbing crisis. A sewer backup requires immediate attention to protect your family’s health and your home’s structure, often calling for emergency plumbing services to resolve the issue safely and effectively.
Common Causes of Sewer Backups
Sewer backups don’t just happen out of nowhere. They are usually the result of a blockage in your home’s private sewer line or the city’s main line. One of the most common culprits is tree roots, which are naturally drawn to the moisture in sewer pipes and can grow into them, causing cracks and blockages. Another major cause is improper disposal of certain items. Pouring cooking fats, grease, and oil down the drain can create solid masses that clog pipes. Similarly, flushing things that don’t dissolve, like wet wipes (even the “flushable” kind), diapers, and hygiene products, will inevitably lead to a clog. Over time, older pipes can also break down or collapse, creating a blockage that needs professional repair.
Warning Signs to Look For
Your plumbing system will often give you hints that trouble is brewing before a full-blown backup occurs. Paying attention to these early warning signs can save you from a major disaster. If you notice frequent backups in multiple drains, it’s a clear signal of a deeper issue in your sewer line. Listen for gurgling sounds coming from your drains or toilet, especially after flushing or running water. You might also see water backing up into your shower or tub when you flush the toilet. A persistent, foul odor that smells like sewage around your property is another red flag you shouldn’t ignore. If you spot any of these signs, it’s best to get in touch with a professional right away.
Your First Steps: Immediate Safety Precautions
When you’re facing a sewer backup, your first instinct might be to jump into action. But before you grab a mop, it’s critical to pause and focus on safety. Sewer water isn’t just dirty; it’s a hazardous mix of contaminants, and a flooded area can hide serious dangers like electrical shock. Your immediate priority is to secure the area and protect everyone in your home. Taking a few key precautions right away will prevent a bad situation from becoming a dangerous one. Think of it as creating a safe zone before the real work of cleanup begins.
Protect Yourself and Your Family
The most significant dangers from a sewer backup aren’t always the ones you can see. While the water contains harmful bacteria and viruses, the immediate, life-threatening risks are electrocution and even explosion. If water comes into contact with your home’s electrical system or gas appliances, it creates an incredibly hazardous environment. Do not enter standing water. Your first call should be to a professional who can assess the situation safely. While you wait, stay out of the affected area and focus on keeping your family away from the contamination. An emergency plumbing situation like this requires a calm, safety-first approach above all else.
Shut Off Utilities Safely
Water and electricity are a lethal combination. If the sewer backup has caused flooding, especially in a basement where your circuit breaker, furnace, or water heater are located, you must shut off your utilities. However, do not attempt to do this yourself if you have to walk through water to get to them. Instead, call your gas and electric utility companies immediately and ask them to turn off the services to your home from the outside. This is the only way to ensure the area is safe to enter later. Never use matches or lighters in a flooded area, as flammable gases could have collected.
Keep Children and Pets Away
A flooded area is no place for kids or pets. The contaminated water poses significant health risks, and children and animals are often more susceptible to the bacteria and pathogens found in raw sewage. Their natural curiosity can also lead them into unsafe situations. Before you do anything else, make sure your children and pets are secured in a separate, clean part of the house, far from the affected area. If the backup is widespread, it may be best to have them stay with a friend or family member until your home has been professionally cleaned and sanitized. Keeping them safe allows you to focus on addressing the problem without worry.
Gather Your Cleanup Gear
Before you can even think about cleaning, you need to suit up. Tackling a sewer backup without the right equipment is not only ineffective, it’s a serious health risk. Think of it like preparing for a messy, hazardous project, because that’s exactly what it is. Having everything you need on hand before you start will make the process smoother and, most importantly, safer. We’ll break down your cleanup kit into three main categories: personal protective gear, tools for removing the mess, and the supplies you’ll need to disinfect everything afterward.
Essential Personal Protective Equipment (PPE)
Let’s be direct: sewage is hazardous. It’s filled with bacteria, viruses, and other pathogens that can make you very sick. Your top priority is creating a barrier between you and the contamination. Start with waterproof, steel-toed boots and heavy-duty rubber gloves that go up to your elbows. It’s also a good idea to wear safety goggles to protect your eyes from splashes. For respiratory protection, an N95-rated mask or a respirator is essential to avoid inhaling harmful airborne particles. Wear old clothing that you can throw away afterward or, even better, disposable coveralls. This isn’t a time to cut corners; your health comes first.
Tools for Water and Waste Removal
Once you’re protected, it’s time to remove the standing water and solid waste. For smaller jobs, a wet/dry shop vacuum will be your best friend. Just remember that its contents will be contaminated and need to be disposed of properly. If you’re dealing with several inches of water, you may need to rent a submersible pump to speed up the process. You’ll also want sturdy buckets for carrying out sludge and solid debris, a shovel or scoop, and plenty of heavy-duty trash bags. Having these cleanup tools ready will help you clear the area efficiently so you can move on to the critical cleaning and sanitizing phase.
Cleaning and Disinfecting Supplies
Removing the water is just the first step. Now, you have to assume every surface the sewage touched is contaminated. You’ll need a low-sudsing detergent to scrub down non-porous surfaces first. After cleaning, the real work of disinfecting begins. A solution of one cup of household bleach per gallon of water is effective, but be sure the area is well-ventilated. Alternatively, you can use a hospital-grade disinfectant. Look for products specifically labeled as an EPA-registered disinfectant to ensure they kill harmful germs. For stubborn organic matter, an enzyme-based cleaner can also be very helpful. Grab plenty of scrub brushes, sponges, and rags that you can toss out when you’re done.
A Step-by-Step Guide to Sewer Backup Cleanup
Okay, you’ve taken the initial safety precautions. Now it’s time to face the cleanup. Tackling a sewer backup is a serious job, but you can manage it by following a clear, methodical process. The key is to work carefully, from removing the initial mess to deep cleaning and sanitizing every affected surface. This guide breaks the process down into manageable steps to help you restore your space safely and effectively. Remember, your health is the top priority, so don’t cut corners. If at any point the job feels too overwhelming, our emergency plumbing team is always ready to handle these tough situations for you.
Assess and Document the Damage
Before you start cleaning, take a moment to assess the situation. Put on your protective gear and carefully walk through the affected area. Take plenty of photos and videos of the standing water, the source of the backup, and any damaged items. This documentation is crucial for your insurance claim. Make a note of everything that has come into contact with the sewage. If the area isn’t cleaned and dried properly, a musty odor can linger, which is a sign of continued microorganism growth. A thorough initial assessment helps you create a solid plan and ensures you don’t miss anything during the cleanup. This step is vital for both your claim and your health.
Remove Water and Solid Waste
With your assessment complete, the next step is to remove the standing water and solid waste. For smaller jobs, you can start by carefully picking up larger debris with paper towels and placing it directly into heavy-duty trash bags. For significant amounts of water, you may need to rent equipment like a wet/dry vacuum or a submersible pump. These tools are essential for removing the bulk of the liquid efficiently. Work from the edges of the spill inward, removing as much of the sewage as you can before moving on to the cleaning phase. This initial removal is messy but necessary to prepare the area for deep sanitization.
Clean and Clear All Surfaces
Once the standing water and solids are gone, it’s time to clean. Use your wet/dry vacuum to suck up any remaining dirty water and loosened mess. After vacuuming, you’ll need to treat every surface the water touched as contaminated. This includes floors, walls, and any furniture that was in the area. A simple and effective cleaning solution can be made with household bleach and water (always follow the product’s safety instructions). Spray the solution over all affected hard surfaces and let it sit for a few minutes before wiping it down. For more complex situations or if you’re unsure about the process, our team can take over to ensure a professional and thorough cleanup.
How to Properly Sanitize After a Backup
Once the standing water and solid waste are gone, it’s time for the most critical step: sanitizing. This is about more than just wiping things down. Sewage isn’t just dirty water; it’s a hazardous mix of waste, bacteria, viruses, and other pathogens that can cause serious illness. Cleaning removes the visible dirt, but sanitizing is what kills these invisible threats left behind on your floors, walls, and belongings. Skipping this step or not doing it thoroughly can lead to lingering odors, mold growth, and potential health problems for your family long after the water is gone. Taking the time to do this properly is the only way to ensure your home is truly safe again.
This part of the cleanup can feel overwhelming, especially when you’re already dealing with the stress of a backup. Remember, if the scope of the damage is too large or you’re not comfortable handling these materials, our team is always here to help. We manage these situations with professional-grade equipment and a focus on safety, offering emergency plumbing services to get your home back to normal quickly and safely. Your family’s health is the top priority, so don’t hesitate to call for backup when you need it.
Choose the Right Sanitizing Solutions
You don’t need to buy expensive, specialized products to effectively sanitize your home. A few common household cleaners can create a powerful disinfecting solution that will get the job done. A great option is to mix 8 tablespoons of standard laundry bleach into one gallon of water. Alternatively, you can combine 2 and a half tablespoons of a disinfectant cleaner like Lysol or Pine-Sol with one gallon of water. When working with these chemicals, safety is key. Always wear waterproof gloves and eye protection, and open windows and doors to ensure the area is well-ventilated, as the fumes can be strong.
Sanitize Different Surface Types
Every surface that came into contact with the contaminated water needs a two-step cleaning and sanitizing process. First, wash all affected hard surfaces, including walls, baseboards, and non-porous flooring, with warm or hot water and a mild soap. Use a scrub brush to work the soap in and lift away any residue. After washing, rinse everything thoroughly with clean, warm water to remove leftover soap and grime. Now you’re ready for step two: applying your sanitizing solution. This two-step approach is crucial because it ensures the sanitizer can directly attack and kill any remaining microorganisms without being blocked by a layer of dirt.
Clean and Restore Salvageable Items
When it comes to your belongings, you’ll need to be ruthless. The rule of thumb is: when in doubt, throw it out. Porous items that absorb water easily, like carpets, rugs, upholstered furniture, mattresses, and books, are nearly impossible to fully disinfect and should be discarded for your safety. For non-porous items, you have a better chance. Hard plastic toys or sealed canned goods, for example, can often be salvaged. Scrub them with soap and water, then soak them for at least 15 minutes in a bleach solution (one ounce of bleach per gallon of water) to ensure they are safe. For valuable or sentimental items you’re unsure about, consulting a professional water damage restoration expert is your best bet.
What to Keep vs. What to Toss
After a sewer backup, one of the most difficult tasks is sorting through your belongings. It can be heartbreaking to see personal items damaged, but your family’s health has to be the top priority. Sewage contains harmful bacteria, viruses, and other contaminants that pose serious health risks. Deciding what to keep and what to throw away isn’t about an item’s monetary or sentimental value; it’s about whether it can be made completely safe again.
The main factor in this decision is the material of the item. Porous materials, which absorb water like a sponge, are nearly impossible to fully sanitize. Non-porous materials, which have hard surfaces that resist water, are much more likely to be salvageable. Before you start, remember that this entire situation is a plumbing emergency. If you feel overwhelmed or unsure about how to proceed safely, our team is always ready to help with emergency plumbing situations. Taking the right steps now will protect your home and health long after the water is gone.
Items You Can Safely Clean
You can salvage most items made from hard, non-porous materials. Think of things like glass, metal, solid wood furniture, and hard plastics. Because these materials don’t absorb contaminated water, you can effectively clean and sanitize their surfaces. The process involves first washing the item with soap and hot water to remove all visible dirt and grime. After it’s clean, you must apply a disinfectant to kill any remaining germs.
It’s crucial to be thorough. If an item isn’t cleaned and dried properly, a musty odor can develop, which is a clear sign that harmful microorganisms are still present. Always wear your protective gear when handling these items, even if you plan to salvage them.
Items to Throw Away Immediately
This is the hard part, but it’s not worth risking your health. You should immediately discard any porous items that absorbed sewage. This includes carpets and rugs, mattresses, pillows, upholstered furniture, stuffed toys, books, and paper products. These materials soak up contaminants deep into their fibers, and it’s virtually impossible to sanitize them completely. The same goes for particleboard furniture, which will swell, warp, and trap contaminants.
Also, throw away any food, drinks, or medicine that came into contact with the sewage, even if the packaging looks sealed. In some cases, fixtures that were submerged might also be a loss. If your toilet was damaged in the backup, a simple fix might not be enough, and you may need a full toilet repair or replacement.
Handling Porous vs. Non-Porous Materials
Understanding the difference between porous and non-porous materials is key to a safe cleanup. Porous materials, like drywall, fabric, and insulation, have tiny holes that allow water and contaminants to soak in deep. Non-porous materials, like sealed concrete, metal, and glass, have a solid surface that resists absorption. While the rule of thumb is to toss anything porous, there are some exceptions for semi-porous items, like solid wood studs inside a wall. If they are structurally sound, they can sometimes be saved if they are professionally cleaned, disinfected, and thoroughly dried.
However, treat every single item the water touched as contaminated until it has been properly sanitized. When you’re faced with a tough decision, always choose the side of caution. If you can’t be 100% certain an item is clean and safe, it’s better to let it go. For complex jobs involving your home’s structure, our wide range of plumbing services can help you restore your home safely.
How to Dry the Area and Prevent Mold
Once you’ve cleaned and sanitized, the next step is absolutely critical: drying everything completely. Moisture is the number one ingredient for mold growth, and after a sewer backup, you have plenty of it. Simply wiping surfaces dry isn’t enough. You need to pull moisture out of the air, drywall, and flooring to prevent long-term damage and serious health risks. This final phase of the cleanup is all about being thorough and patient.
Use Fans and Dehumidifiers to Dry Everything
To effectively dry a saturated space, you’ll need more than just towels. Your goal is to create an environment that actively pulls moisture from every surface. Start by placing high-powered fans throughout the affected area to keep air circulating and speed up evaporation. Next, bring in one or more dehumidifiers to pull that moisture out of the air. For a serious backup, consider renting industrial-grade equipment. Run the fans and dehumidifiers 24/7 for several days. Even when surfaces feel dry, moisture can be trapped deep inside, so don’t rush this step. It’s a key part of any professional emergency plumbing response.
Ensure Proper Ventilation
While fans and dehumidifiers work inside, you also need to get the damp, contaminated air out. Proper ventilation is essential for both drying and your safety. If weather permits, open windows and doors to create a cross-breeze that pushes moist air outside and brings fresh air in. This helps the area dry faster and dissipates lingering odors from the sewage or cleaning solutions. Working in a well-ventilated space is much safer and prevents you from breathing in harmful fumes or airborne contaminants. Think of it as letting your house take a deep breath after a stressful event.
Monitor for Mold Growth
Mold can begin to grow in as little as 24 to 48 hours, so you need to be vigilant. After drying, keep a close eye (and nose) on the area for the next few weeks. Look for visible signs of growth, like black, green, or white spots on walls or baseboards. Even if you don’t see anything, a persistent musty or earthy smell is a major red flag that mold is growing somewhere hidden. If you notice either of these signs, it means the area wasn’t dried completely. At this point, it’s best to contact a professional to handle the situation safely.
Understand the Health Risks
A sewer backup is more than just a messy inconvenience; it’s a serious biohazard event happening inside your home. The water from a sewer line, often called black water, is heavily contaminated with waste, bacteria, and other dangerous materials that can pose significant risks to your family’s health. Exposure to these elements can cause illness, and the moisture itself can lead to mold growth, which creates long-term air quality problems.
Beyond the biological dangers, a major backup can also create physical hazards. Standing water introduces the risk of electrocution from submerged outlets and appliances, and in rare cases, sewer gases can build up to flammable levels. Because the stakes are so high, it’s important to treat the situation with extreme caution. Your first priority should always be safety. If you feel overwhelmed or unsure about how to proceed, the safest option is always to call for professional help. A team with experience in emergency plumbing can manage the cleanup safely and effectively, protecting both your home and your health.
Health Concerns from Sewage Exposure
It’s critical to understand that sewer water is not just dirty water. It contains harmful things like viruses, bacteria, and other germs that can make people very sick. Contact with contaminated water or surfaces can lead to gastrointestinal issues and other infections. For this reason, you should treat everything the water has touched as a potential source of illness until it has been thoroughly cleaned and sanitized. Remember to also consider the less obvious dangers. Standing water near electrical outlets or appliances creates a serious risk of electric shock. It’s essential to shut off the power to the affected area before you even think about starting the cleanup process.
Know When to See a Doctor
Even if you wear protective gear, exposure can still happen. Pay close attention to your health in the days following a sewer backup cleanup. If you or anyone in your household begins to experience symptoms like nausea, vomiting, diarrhea, or fever, it’s important to seek medical attention immediately. Inform your doctor that you may have been exposed to sewage so they can provide the appropriate care. Since sewage is so dangerous for your health, the best way to protect yourself is to avoid direct contact altogether. Calling professionals to handle the cleanup is the most effective way to ensure the area is made safe without putting your well-being at risk.
When Should You Call a Professional?
Tackling a home project yourself can be incredibly rewarding, but a sewer backup is one of those times when calling for backup is the smartest move. While you might be able to handle a very minor spill, a significant sewage event poses serious risks to your health and your home’s structure. Knowing when to step back and let an expert take over is key to a safe and effective cleanup.
The decision often comes down to two things: the size of the mess and the potential costs involved. If you’re facing widespread water, contaminated materials, or you’re just not sure where to start, it’s time to call in a pro. A professional has the right equipment and training to handle the situation safely, protecting you and your family from harmful contaminants.
Signs the Job Is Too Big for DIY
It’s tempting to try and manage a sewer backup on your own, but some situations are simply too hazardous for a DIY approach. Sewage is more than just dirty water; it contains bacteria, viruses, and other germs that can cause serious illness. If the backup is extensive, covering a large area of your basement or home, it’s a job for a professional. You should also call for help if the contaminated water has soaked into porous materials like drywall, carpeting, or insulation. These materials are nearly impossible to sanitize properly without specialized equipment and can become a breeding ground for mold.
If you’re unsure of the source of the backup or if the flow of sewage hasn’t stopped, you need an expert immediately. A professional plumber can diagnose the underlying issue and provide emergency plumbing services to prevent further damage. Choosing to call a professional isn’t admitting defeat; it’s making the responsible choice for your home and your family’s health.
What to Know About Costs and Insurance
One of the first questions on anyone’s mind during a home emergency is, “How much will this cost?” Professional sewage cleanup can range from $2,000 to $10,000 or more, depending on the extent of the damage. While that number can be intimidating, it reflects the cost of a thorough job that includes water extraction, sanitizing, drying, and repairing damaged structures. Trying to cut corners can lead to lingering health hazards and more expensive mold problems later.
It’s also important to understand what your homeowner’s insurance covers. Most standard policies do not include coverage for sewer backups. You often need to purchase a separate rider or add-on for this type of protection. The best time to figure this out is before you need it. Review your policy or call your insurance agent to see what’s covered. If you find yourself needing a quote for repairs, you can always contact us for a clear and honest assessment.
How to Prevent Future Sewer Backups
After cleaning up a sewer backup, the last thing you want is a repeat performance. Taking a few proactive steps can save you from dealing with this messy, stressful situation again. Prevention is all about being mindful of what goes down your drains and equipping your home with the right safeguards. By combining regular professional check-ups with a few key installations, you can protect your property and your peace of mind. It’s much easier and more cost-effective to stop a problem before it starts than to clean up the aftermath.
Think of it as a two-part strategy: consistent care for your existing plumbing system and smart upgrades to fortify your home against external issues. A little bit of maintenance goes a long way in keeping your pipes clear and functional. At the same time, installing devices designed to stop sewer backflow adds a powerful layer of defense. This isn’t about waiting for disaster to strike; it’s about creating a resilient plumbing system that can handle everyday use and unexpected strain from the municipal line or severe weather. Many homeowners are surprised to learn that the responsibility for the sewer line running from their house to the street falls on them. Understanding this makes proactive care even more critical. Let’s walk through how you can put these strategies into action.
Schedule Regular Plumbing Maintenance
Your home’s plumbing is a complex system, and out of sight shouldn’t mean out of mind. The most common culprits behind sewer backups are things that should never have gone down the drain in the first place, like cooking grease, “flushable” wipes, and hygiene products. Over time, these items build up and create stubborn clogs. Tree roots are another major issue, as they can sneak into tiny cracks in your sewer line and grow, causing a complete blockage.
Scheduling a professional plumbing inspection once a year allows a technician to spot these problems early. Using tools like a sewer camera, we can see exactly what’s happening inside your pipes. If we find tree roots or a tough clog, we have the right equipment to clear it out properly. Regular plumbing services are a small investment that prevents major headaches down the road.
Install Preventive Devices
While maintenance keeps your internal pipes clear, you also need protection from issues in the main city sewer line. Heavy rain or a municipal blockage can force sewage back toward your home. A backflow preventer is your best defense against this. This simple device acts like a one-way gate, allowing wastewater to leave your home but automatically closing to block any from flowing back in. We can help you choose and install the right backflow preventer for your property.
For homes with basements, a sump pump is another essential tool. It works to remove groundwater that accumulates around your foundation, preventing it from seeping in and causing floods. A reliable sump pump keeps your basement dry and protects it from water damage, which is especially important during Detroit’s heavy rains and thaws. This device is a key part of keeping your lower level safe and dry year-round.

Frequently Asked Questions
How can I tell if I have a main sewer backup or just a simple clogged drain? A simple clog usually isolates itself to one spot, like a single slow-draining sink or a toilet that won’t flush. A main sewer line backup, however, is a system-wide problem. You’ll see symptoms in multiple places at once, especially on the lowest level of your home. For instance, flushing an upstairs toilet might cause water to gurgle or rise in your basement shower drain. If multiple fixtures are acting up, it’s a strong signal the issue is in your main sewer line.
What is the absolute first thing I should do if I see sewage backing up? Before you even think about cleaning, your first move must be to ensure everyone’s safety. Immediately get all people and pets out of the affected area and keep them away. Do not walk through the standing water, as it is hazardous and may hide electrical dangers. If water is near outlets or appliances, call your utility companies to shut off the power and gas from outside your home. Securing the area is always the first and most important step.
Is it really necessary to throw away my carpet and furniture after a backup? I know it’s difficult, but for most soft, porous items, the answer is yes. Materials like carpet, mattresses, and upholstered furniture absorb contaminated water deep into their fibers, making them nearly impossible to fully sanitize. Attempting to clean them creates a significant risk for mold growth and lingering bacteria that can affect your family’s health. When you’re weighing the cost of an item against your well-being, it’s always best to let it go.
My insurance policy is confusing. How do I know if a sewer backup is covered? You’re not alone; insurance policies can be hard to understand. Most standard homeowner’s policies do not automatically cover damage from a sewer backup. This protection is typically an optional add-on, often called a “water backup” endorsement. The most direct way to find out is to call your insurance agent. Ask them to review your policy with you and confirm exactly what is and isn’t covered. It’s a five-minute call that can save you a lot of stress later.
After cleaning up, how can I be sure my home is truly safe from mold and bacteria? True safety comes from being extremely thorough with the final drying and sanitizing steps. After cleaning, the area must be dried completely with fans and dehumidifiers running for several days. Even after surfaces feel dry, you should keep an eye on the area for a few weeks. A persistent musty smell is a clear sign that moisture is still trapped. If you have any doubt, the best way to get peace of mind is to have a professional handle the cleanup. They have the tools to measure moisture and ensure the job is done right.
