Home inspections are crucial when selling a property or ensuring it’s in good shape. A water damage basement is one of the most common issues homeowners face during these inspections. This not only lowers the value of your property but can also lead to more severe issues like structural damage and mould growth.

Having a wet basement isn’t the end of the world. With the proper precautions and remedies, you can pass your home inspection even if there’s a history of water damage basement. Here are the top five tips to ensure you make the cut.

#1. Identify the Source of the Leak

Pinpointing the source of a basement leak is like solving a mystery. Every damp spot, every discoloration, tells a story. Before embarking on any interior basement waterproofing projects, it’s imperative to discern the cause.


Often mistaken for a leak, condensation can form when warm, moist air meets the cooler basement walls and floors. Tools like a hygrometer can help measure humidity levels, indicating whether condensation is your culprit. Addressing this may require improved ventilation or the use of dehumidifiers. Moreover, it may be time for windows replacement if you see the water behind your window panes.


This is water that seeps in from the outside, especially after a heavy downpour or in flooded areas. Check if water pools around the foundation of your home after rainfall. This might mean your soil doesn’t absorb water well, or the water has nowhere else to go due to clogged drainage systems. Water staining patterns can give clues if runoff is the issue – the water will often leave traces of its path. In this case, your preferred choice is exterior basement waterproofing.

Groundwater swelling

Basements can often get flooded in areas where the water table is high. The surrounding soil might become saturated, causing a steady rise in water levels inside the basement. Look for signs like consistently damp spots on floors, especially after rain or if you’re in a low-lying area.

In essence, identifying the source of a leak is like piecing together clues for water damage basement. A detailed inspection, possibly with a WillFix professional’s help, can determine the exact source and guide subsequent actions.

#2. Implement Proper Drainage Solutions

Improper drainage can lead to a plethora of problems in your basement. To avoid it, ensure your gutters and downspouts are clean, and direct water at least 5-6 feet away from your home’s foundation.

Make sure the land around your home slopes away from it. This will prevent water pooling near your foundation and possibly seeping into your basement. Building a retaining wall, in this case, might be a great idea.

#3. Use Water-Resistant Paint and Sealants

After ensuring proper drainage and addressing the source of the leaks, consider applying a waterproof sealant to your basement walls and floors. This acts as an additional barrier against moisture. Many home renovation contractors use it for foundation crack repair.

Water-resistant paints can be applied to the basement’s interior walls as an additional help in waterproofing the basement. While sealants and concrete crack repair services can be used on both interior and exterior surfaces, preventing water penetration.

#4. Install a Sump Pump and Dehumidifier

Water accumulation in the basement isn’t just a passing inconvenience; it can cause structural damage and mould growth, which pose health risks. This is where tools like sump pumps and dehumidifiers come into play.

Sump Pump

Think of this device as your basement’s knight in shining armour. Installed in the lowest part of a basement or crawlspace, the sump pump’s primary job is to keep the area dry and evacuate water that accumulates. There are different types of sump pumps – submersible and pedestal. The former is housed inside the sump pit, while the latter stands upright outside it. The choice between them depends on your basement’s size and the water it generally receives.

Regular sump pump maintenance, including:

  • Checking its float switch; 
  • Cleaning the pit; 
  • Running tests can ensure longevity and efficiency. 

Installing a battery backup can also be a lifesaver during power outages.


Basements, by nature, are prone to humidity due to their underground location. A damp basement becomes a breeding ground for mould and mildew. Dehumidifiers remove excess moisture from the air, preventing condensation and its associated problems. There are several types of dehumidifiers – refrigerative, desiccant, and whole-house. Each serves a different purpose and capacity. When choosing one, consider the size of your basement, the average humidity levels, and your budget.

#5. Regularly Inspect and Repair Cracks

Over time, your home’s foundation can develop cracks due to settling or other stresses. These can become entry points for water. Checking for new cracks or monitoring existing ones can be crucial. Use a high-quality, waterproof sealant to prevent water ingress.

In Conclusion

Water damage in the basement can be a serious concern, but it’s not insurmountable. By following these steps, you can ensure that your home stands up to scrutiny during an inspection, preserving its value and ensuring the safety and health of its inhabitants. Addressing water damage proactively and understanding the causes can make the difference between a passed inspection and a potential roadblock in your home’s journey. Don’t wait for an inspection to reveal problems; tackle them head-on and maintain your home’s integrity.
