If you’ve recently done a house painting project in your basement, you should waterproof the area, as leaks can destroy a paint job and cause other problems. Basement moisture issues are common, but waterproofing will prevent leaks from developing in the first place. Here are a few more reasons to use this service.

Why You Should Waterproof Your Basement

1. Prevent Mold Growth

A minor leak can quickly lead to mold growth, damaging your house painting job. Basements are naturally dark and humid, and when a damp spot appears on the wall, mold or mildew can grow within 24 hours. If toxic mold growth goes unnoticed, it can cause respiratory issues, headaches, and other health problems.

2. Protect Stored Items

Even a minor leak or humidity can damage these items, causing rapid deterioration. By reducing indoor humidity, basement waterproofing will also lower your household HVAC costs, as air conditioners generally don’t have to work as hard to keep the home comfortable during the summer when the air is drier.

3. Stop Foundation Erosion

Hydrostatic pressure from surrounding groundwater can crack basement walls and floors, causing leaks. This is because groundwater—especially rain runoff—will naturally push against anything blocking its path, such as rocks, tree roots, or your home’s foundation. Waterproofing provides a protective layer— by coating basement surfaces with a strong epoxy or urethane sealant—that stops cracks, reducing leaks and preventing foundation issues. The installation of a drainage or sump pump system will also keep down water levels. In the long run, you’ll save money since you won’t have to pay for repairs.
