“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”

“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.
