"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!"
