"James and Mike also did the foundation and patio work as well as walls and steps. They are simply the most professional yet friendly people to to do business with. Their attention to detail and quality of execution is simply amazing. Highly recommended!!!"

"Jack and his crew were thorough, professional and courteous throughout the entire waterproofing project for the basement, which included outside drainage work to better direct water away from the house, and the foundation repairs that were needed. He provided a detailed estimate and explained all facets of the project. Jack also provided additional recommendations for repairing the house gutters and downspouts. The home was built in the 1940's and the basement would flood following rain. Since the repairs, three rain storms within five weeks, each with over 3 inches of rain, have occurred and the basement waterproofing project was immediately tested. It has remained dry!"

"The entire process was great. Every step of the way they checked to ensure it was the way we wanted it. The end result was great like having a new yard. Would not hesitate to have them do more work ."

"This was a professional job from start to finish. Channel drain project. Every aspect was done correctly. Slade explained, gave me my options, and then showed up as scheduled to do the job. He takes a lot of pride in his work. He used concrete to set the drains in place to make sure they will not shift over time. He was careful about the pitch of the drains. Left a neat work site. I have no doubt the installation will last a long time. Works very well. Worth every dollar. No need to look any further. 5 stars."
