Can You Waterproof a Finished Basement?
by Holly Richards-Purpura | Published August 13, 2024
While many new homes have rigorous waterproofing standards for basements, older homes may need waterproofing methods to ward off moisture and water damage. If your finished basement shows signs of water damage, you may be wondering if you can waterproof a finished basement. Fortunately, there are several methods our basement waterproofing specialists use to waterproof finished basements.
Here’s what you need to know about solving your unique basement issues.
Why Waterproof a Finished Basement?
If your basement has humidity and moisture issues, it’s important to resolve them promptly because:
- Avoiding water issues could present health and safety risks and lead to expensive repairs.
- Leaks and water damage can decrease your home’s value.
- Mold can spread and lead to poor air quality, asthma, allergies, and other respiratory illnesses.
- Your home’s wooden framework can be damaged by chronic moisture, causing structural issues.
- Unaddressed leaks can ruin your valuables.
Exterior Issues and How to Solve Them
Your foundation and surrounding areas can direct water straight towards your basement. Our team inspects the perimeter of your home for signs of leaks.
5 Typical Exterior Problem Signs
Common signs of exterior foundation problems include:
- Cracks in your foundation
- Expansive soil
- Heavy rainfall
- Gutter issues
- Incorrect grading
Exterior Waterproofing Solutions
Common solutions, including footing drains, exterior wall dampproofing, and French drains, often fail and lead to water in your basement. You have the option to replace them, but that’s not going to stop water from damaging your home.
However, you can ensure your gutters and downspouts remain free of clogs and damage and grade your yard so water drains away from your home.
Interior Basement Problems & Their Solutions
Part of Ohio Basement Authority’s extensive evaluation process involves inspecting the basement interior for any issues and pinpointing the cause.

- Plumbing leaks
- Malfunctioning sump pump
- Excessive humidity from temperature changes
Waterproofing a Basement Interior
While tackling exterior problems can seriously mitigate your basement’s leakiness, many exterior waterproofing solutions are disruptive to your yard. In most cases, interior basement waterproofing may be a less invasive solution that still waterproofs your finished basement.
Our interior basement waterproofing solutions are more discreet than exterior solutions and are part of a comprehensive plan that keeps your home dry. They include interior drainage, sump pumps, vapor barriers, and dehumidifiers.
Be aware that large leaks and major structural issues may require some finishing removal, including basement walls or floors.

Basement Finishing FAQs
Basement wall waterproofing should be performed before starting the finishing process. This preventative measure protects against moisture seepage, mold, mildew, and wood rot, ensuring your basement remains permanently dry and healthy.
Basement walls, insulation, and utility wiring should be completed first before finishing the floor. This ensures the space remains safe and dry. Our basement finishing experts will ensure building codes and laws are in place before beginning the process.
Some consider basement finishing a DIY project, but we don’t recommend it. Basement finishing requires specialized skills like electrical work, drywalling, and knowledge of your foundation to ensure a long-lasting and safely implemented result.
