“Kenseal is a tremendous help. They delivered everything on time and as promised. We are always pleased with Kenseal’s service — they go above and beyond”

Jack Victor from JD Long Masonry

“We worked with Kenseal to give WakeMed a complete Tremco system above grade. This may have sealed the deal for us in getting this very important project. I got together with Kenseal early on and let them know what I anticipated our material requirements to be, and they made it happen. Throughout the project, Kenseal kept up with our material needs and made sure they had what we needed in stock. I look forward to the next project that we can work on together.``
