Sill pans, flashing tape and drip caps that send water out and away so windows stay dry for years.
Most window leaks are not the window itself. They are failures of the flashing, the thin layer of material that directs water around and out of the opening. Good flashing starts at the sill, laps up the sides and finishes at the head with a drip cap, and each layer sheds water over the one below it. When it is done wrong or left out, water gets behind the trim and into the wall. Homeowners in Nashville ask us about flashing when they see staining or soft wood around old windows.
We install flashing as part of every replacement and new construction job, working with the house wrap, the siding and the window flange. We use sill pans and self-adhered flashing tape, lap pieces in the right order and finish the head with a drip cap or head flashing. For existing windows, we open the trim as needed, repair the layer and seal it. We explain why each layer matters, so you know what is behind the finish.
Flashing works like roof shingles: each layer overlaps the one below, so water flows down and out rather than behind.
A pan under the window catches any water that gets in and sends it to the outside, which protects the wall below.
The top of the window needs a cap that sheds water away from the trim and the glass.
Tapes, sealants and wraps must work together, and we choose products that stick to each other and to your wall.
