"Great all around experience . I had a French drain system and sump pump installed . I canâ t speak highly enough about the honest advice and great pricing. Hydroseal came highly recommended and the price was much more reasonable than the competitors I received quotes from. I finally have a dry basement and I would confidently recommend them!"

"Erick is a truly good man who stands by his word/price. I had two bathrooms remodeled and I am thrilled with the end result. Erick made sure that any inconvenience to my family was minimal and at the end of every day their clean up incredible. After getting three other estimates, I had Erick come over to estimate the price and his price was 20% lower than some of the other estimates. Erick is my go to contractor, I trust him and I intend to have him do some more work this spring. Feel safe hiring Erick, you will not be sorry."

"Contacted company on line and they called me back within 10 minutes. Asked several questions about issue I was having and set up an appointment to have someone assess the problem at no charge within the week. Issue clearly identified and suggested remedy explained in detail. Hired company to do job. The two men who did the job were very knowledgeable, professional and followed Covid guidelines while at my home. They also took precautions to keep my home clean and protected from dust and debris before and after job was done. Very pleased with the work that was done and definitely would recommend."

"James and his crew were a pleasure to work with. Very dependable, honest, knowledgeable and kept me informed every step along the way about the project. They show up everyday on time and work consistently until the project is finished. Once they are done they clean up and leave no trash behind. I have used them for several projects because of their work ethic and because of my satisfaction with the completed projects. Their work is guaranteed . I highly recommend them and would definitely use them again."
