"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!"

Basement Waterproofing FAQs, answered by experts

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.
