Our Services

Foundation Crack Repairs

If you have cracked and leaky basement walls, Seepage Stoppers’ high-pressure polyurethane foam injection process is the best solution for sealing your foundation. We can also seal the exterior perimeter of your foundation for added water damage protection.

Protecting your foundation is vital to protecting your home’s structure and value. From French Drains to Sump Pumps to Foundation membranes, our interior and exterior waterproofing systems will ensure no water seepage will penetrate your basement or crawlspace and cause more damage.

Water Damage Restoration

Did your basement already experience flood damage? We can remove(extract) remaining water, repair the damage and restore the structural integrity of your foundation. Plus, our experienced contractors will identify the source of all leaks and seal the foundation to prevent future damage.
