"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!"

"Alex was amazing!! We had a crack in our foundation that another company attempted to repair numerous times. We were fortunate enough to hear about ProSeal and I am happy to report not only did Alex repair the crack to near perfection but the work was done timely, neatly and his customer service skills are top notch. I would HIGHLY recommend ProSeal for all of your foundation needs."

"These guys were great. I had mold in my basement walls. This company was very knowledgeable and their price was very good. In one day not only was all the mold gone but they also waterproofed my basement. They were professional and fast. I highly recommend them."

"Just excellent start to finish - I’ve been battling water in my basement for years and finally have no more anxiety during a heavy rainstorm. The new humidifier and waterproofed basement was money well spent - and the work and care from this top notch team was outstanding. Highly recommend them. Quality work at a fair price."

"Lorenzo was responsive, prompt and fair. He and his team installed a drywall for us to help with water in our basement 6 months ago. So far, everything is working well."
