Windows and Doors

Flashing and drainage systems around windows and doors are essential for preventing water infiltration and protecting the building envelope. Flashing, typically made of metal, rubberized asphalt, or composite materials, directs water away from openings, while drainage systems help manage any moisture that gets behind exterior cladding. Proper installation ensures that water is diverted away from vulnerable areas, reducing the risk of leaks, mold, and structural damage. By enhancing moisture control, flashing and drainage systems improve the longevity and performance of masonry walls.
