Lisa Starr, Administrator
The Conrado Company, Inc.

Our company and I have used Renaissance Stone Care & Waterproofing almost exclusively for the last 15 years as a Waterproofing contractor/consultant as well as for restoration of stone and masonry surfaces.

My experience with Renaissance has always been positive, especially in situations where architectural specification and direction is less than complete. They have shown a broad range of knowledge in waterproofing a multitude of materials, and have been able to troubleshoot and repair existing problems.

Renaissance has been a constant in a field of evolving sub-contractors."

Dan Francesconi, Superintendent

In my experience Renaissance is the most thorough, courteous, trustworthy, and reliable subcontractor I have ever employed. They do what they say they will without mistakes."
