Your One-Stop Foundation Repair

It’s inevitable. All concrete basement foundations will crack at some point and require repairs. When the ground around your foundation’s exterior settles, the concrete becomes vulnerable to cracking and eventually water seepage. Let the professionals at Seepage Stoppers recommend the best basement waterproofing methods and foundation repair solutions before serious damage occurs.

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.

Basement Waterproofing

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.

Frequently Asked Questions

What is water seepage?

Water seepage is when water flows through small holes or cracks in porous material. It usually occurs after heavy rainfall when the groundwater levels rise and the surrounding soil causes additional pressure against your home’s foundation.

What causes water seepage?

While heavy rainfall is one of the most common causes of water seepage, improper downspouts or clogged gutters and window wells that allow water to accumulate around your home’s foundation can also cause seepage. In addition, improper grading around your home can also be a cause.

What are signs of water seepage?

Common signs of water seepage are cracks in the home’s foundation. You may also see water stains on the walls or floors of your home. Musty or poor indoor air quality also indicates that mold and mildew are growing which can often become a health issue for your family.

Are your estimates free?

Yes. Our free estimates include an inspection of your foundation for cracks and potential water seepage, along with an assessment report and cost for the appropriate solution.

Can you provide estimates over the phone?

Due to the number of variables that come with foundation and water issues, it’s difficult to provide estimates over the phone without assessing each case in-person. Every home—and every problem— is different and without an inspection, it’s impossible to know which of our many basement solutions is the right fit for your home.
