HouseChalkWindow flashing
Window flashing is waterproof material installed around window openings to direct water away from the framing and prevent leaks.
Why it matters
Improper window flashing is one of the top causes of hidden water damage in new construction. It leads to rot and mold inside walls.
Where people get this wrong
Window flashing is not the same as caulk around the window trim. Flashing is behind the siding, integrated with the weather-resistive barrier.
Real-world example
The installer applies self-adhesive flashing tape to the window sill and sides, lapping it over the weather-resistive barrier so water sheds outward.
Where this hits your build
This term shows up during construction and affects decisions that are hard to reverse once the work moves forward. Understanding it now saves time, money, and frustration later.
Most people do not just struggle with terms. They struggle with the decisions tied to them.
