"I called American Foundation and Waterproofing regarding a significant, but localized, leak in a basement foundation wall. Michael arrived on time for the inspection appointment and performed a thorough inspection. He identified the cause of the leak and suggested several fixes that I could try myself. If the suggestions do not work, I will definitely hire this company. I believe they are honest, professional, and know what they are doing."

"Blalock waterproofing did a fantastic job in my basement. Cory came out, gave an estimate and completed the job of 60 ft of waterproofing in just 6 days. From estimate to completion in 6 days, amazing. He started on Monday and Wed. Afternoon, cleaned up and job down. He dealt with my stairs- they were in the way, and added some additional support to the 4x4s that had been rotted out from all the water at floor level. Final price was exactly what was estimated. Hire them!"

Basement Waterproofing questions, answered by experts

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.

The primary downside to crawl space encapsulation is the high cost, which can be several thousand dollars. Additionally, the process can make future repairs more complicated by limiting access to plumbing and electrical wiring within the crawl space. Encapsulation also requires sealing off any vents, which can be a disadvantage for home designs that benefit from the airflow they provide. It's recommended to consult with a crawl space contractor to determine if the benefits outweigh these potential drawbacks for your specific home.

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.

Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.
