Customers say: Terrific value

"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!"

"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."

"All their work was excellent. Not only did they replace our roof and repair water damage in our dining room, we had them do other jobs too. Replacement basement windows, outdoor lighting, and fencing. I would definitely hire them again."
