Guide to Handle a Flooded Basement the Right Way

Advanced Basement Waterproofing • November 21, 2025

A flooded basement can happen when you least expect it. It might be caused by heavy rain, a burst pipe, or a drainage issue that went unnoticed. No matter how it happens, finding water in your basement can be stressful. The good news is that there are steps you can take to handle the situation safely and effectively.


At Advanced Basement Waterproofing, we understand how overwhelming it can be to deal with water damage. That’s why we’re sharing this simple step-by-step guide on what to do next and how to get professional help for flooded basement cleanup.





Step 1: Stay Safe and Avoid the Basement


Flooded basement

When you notice flooding, the first thing to do is avoid going into the basement. Standing water can be dangerous if it comes into contact with electricity or hidden debris. Even a few inches of water could pose a safety risk.


Before doing anything, make sure your power is turned off at the main switch if you can reach it safely. If not, wait until professionals arrive. It’s always better to stay safe and have an experienced team handle the inspection.


Our team at Advanced Basement Waterproofing is trained to deal with flood situations. We’ll check the area, assess the risk, and make sure everything is safe before beginning any cleanup.


Step 2: Call for Professional Help


Once you’ve made sure everyone in your home is safe, the next step is to call for professional help. Flood cleanup requires more than just removing water. It also means checking for hidden damage, leaks, and potential mold growth.


Our technicians will arrive promptly, inspect the flooded area, and determine the best way to remove the water quickly. Using professional equipment, we can pump out large amounts of water and start drying the area right away. This helps reduce the risk of further damage to your foundation, floors, and walls.


Step 3: Identify and Fix the Source of the Flood


After the water has been removed, it’s important to find out what caused the flooding in the first place. Basement floods often come from issues such as foundation cracks, unsealed windows, broken sump pumps, or poor drainage outside the home.


Our team will look closely at your basement and determine where the water came from. Once we’ve identified the source, we can make the necessary repairs. That might mean sealing cracks, waterproofing walls, replacing damaged drains, or improving the grading around your home to direct water away.

Fixing the cause early helps prevent future flooding and gives you peace of mind when the next storm hits.


Step 4: Sanitize and Dry the Space


Even after all the water is gone, your basement still needs to be cleaned and sanitized. Floodwater can carry bacteria, dirt, and debris that you don’t want to linger in your home. Any surfaces that were touched by water such as floors, walls, furniture, or storage boxes should be disinfected.


This step is also important for mold prevention. Mold can start to grow in as little as 24 to 48 hours after a flood if the area stays damp. We’ll make sure everything is properly dried using fans, dehumidifiers, and moisture testing to ensure there’s no hidden moisture left behind.


Once the area is dry, we can recommend further protection options such as vapor barriers or basement waterproofing systems to keep the space safe long term.


Step 5: Check for Mold or Odors


After everything is cleaned and dried, keep an eye and nose out for lingering smells or dark spots on walls and flooring. These can be early signs of mold growth.


If you notice any musty smells or stains, contact us right away. We offer complete mold removal and prevention services to stop mold from spreading and affecting your home’s air quality. Our goal is not only to clean up the damage but also to make sure your home stays healthy and dry.


Step 6: Take Steps to Prevent Future Flooding


Once your basement is dry and repaired, it’s a good idea to take steps to avoid the problem from happening again. Some simple prevention tips include:


• Making sure gutters and downspouts are clean and direct water away from your home
• Having your sump pump checked regularly to confirm it’s working properly
• Sealing any small cracks in your foundation before they become bigger problems
• Keeping valuable items off the basement floor in watertight bins
• Scheduling regular basement inspections


Prevention is one of the best ways to protect your home from the stress and cost of flooding.
