"There was a crack in the basement wall from top to bottom that was leaking water onto floor after a heavy rain. James suggested several options but suggested the inexpensive crack filler and sealer first. I had other companies give me estimates and he was by far the cheapest for the same exact work. They arrived on time, cleaned up and are very nice and helpful. Very knowledgeable about waterproofing."

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!"

"They stuck to timeline perfectly.  Did work in a respectful manner.  Abided by town ordinances regarding hours of work.  Were respectful to all neighbors concerns and even managed town concerns and called me when needed. They were as respectful with their staff as they were with me a s a client.  They recommended and prepared land for seasonal and weather conditions so work was most efficient in spring.  They were genuinely concerned about my property as if it was their own and made only reasonable and sound recommendations.  Nothing to just "bring them more business".  Great communication and pacifying any apprehensions in a respectful way. I'd use them again anytime for any project.
