"I contracted with American Foundation & Basement Repairs, LLC for waterproofing services to include replacing the drywall once the installation was complete. The salesman listened to me, made all the changes that I requested, answered my questions, and did it all quickly, efficiently, and without pressure. The work crews were courteous, cleaned up after themselves, hauled away all the debris, and kept me well informed throughout the process. They called daily to let me know when they would arrive since the repair was not at my residence, giving me plenty of time to get there to let them in the house."

"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!"

"David recently came out for a periodic system inspection and promptly replaced a sump pump exit line valve out in the yard that had been damaged by a lawnmower. we discussed adding a backup to the sump pump, which I decided to do. Matthew was out in just a few days to take care of that installation. Everything went quickly and smoothly. These guys are pros."

Basement Waterproofing FAQs, answered by experts

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.
