A maker of caulks, sealants, adhesives and spray foam used around windows, trim and frames.
DAP makes caulks, sealants, adhesives and spray foam, and its products are common in window work. A good bead of sealant keeps water out of the joint between a window and the wall, and low-expansion foam fills the gap around the frame to cut drafts. Homeowners in Nashville see these products on shelves and often ask which one belongs where.
We are an independent contractor and choose sealants for each job. Exterior joints need flexible, weather-resistant products, interior trim gaps often use paintable caulk and gaps around the frame use foam made for windows. We clean and prepare each surface, apply the product neatly and tell you how long it should cure.
