Testimonials

Jeffrey Leal of Nusite Waterproofing found my problem within minutes of examination my basement; a broken drain pipe leading from my kitchen above. No foundation problem. No charge.

A previous Company was talking about the possibility of groundwater coming up through my concrete floor; major costs discussed.

Thank you Jeffrey.

Homestars Review-Basement Waterproofing

Cecil Lindo

I had recently purchased an older home in Toronto. The basement had a running leak from the cold room into the basement. After receiving quotes from many other Waterproofing companies, I found David and Ryan to be honest, fair and trustworthy for the job. Everything explained very clearly, work done on time and the crew cleaned up the area very well on their way out. Happy to refer to Nusite.

Michael Oziel

Our basement leaked! Of course . . . we bought a 100 year old house! But my office needed to be in the basement permanently. I interviewed 10 different companies until we decided on the Steinbergs and their crew at Nu-Site! They are professional, reliable, courteous, honest, and they really make an effort to communicate with the client about every step of the process.

Homestars Review-Basement Waterproofing

Mark Lipton

After several years of chronic leaks, we decided to have our basement waterproofed once and for all. The team over at Nusite was professional, answered my questions during the project and stayed within their quoted price….which is always a concern for me when working with contractors. Great job overall
