"Skyler and TerraFirma far exceeded our expectations. The injection process of the foam raised our cracked garage floor back to level. Skyler’s customer service was the best. I highly recommend TerraFirma and hope that you get Skyler as the person doing the work… you will not be disappointed!"

Basement Waterproofing questions, answered by experts

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don’t have ongoing damage. They’ll also often take preventative measures to stop the issue from recurring in the future.

Your homeowners insurance can cover slab leak repairs, but it really depends on your policy. Some homeowners insurance policies only cover slab leaks caused by natural disasters, while other plans are more comprehensive. You might also want to check your home warranty plan to see if they'll cover the cost of the repairs if one of your appliances caused the leak.

Mold growth is just one common sign of excess moisture in the bathroom. You may also see the paint in the room start to peel away from the walls, or that the walls remain wet for some time after you bathe.

Condensation on the windows is another sign that your bathroom has a potential moisture problem. The room itself may start to smell like mildew.

In many homes, an unfinished basement is an ideal place for an in-ground pool. The concrete floors, protection against water damage, and access to the ground below your home make this a large contender. Speak with a local basement remodeling contractor to ensure your space is right for the large construction.

Alternatives to gutter systems include rain chains and drip edges, which work to disperse rain coming off of your roof to a wider section of the ground to prevent erosion and pooling. These options aren’t standalone alternatives to gutters in all parts of the country because they don’t divert water. They’re often reserved for dry climates. On the ground, you can also opt for a drip path or French drain. These can serve as standalone alternatives, but they’re expensive and can detract from your curb appeal and usable yard.
