Windows fitted, flashed, and finished
Replacement, energy-efficient, and custom windows measured to the opening, sealed and flashed correctly, then trimmed inside and out.
Overview
Windows that seal properly and operate smoothly, installed so water is directed away from the wall rather than into it.
What window installation involves
A window is a hole in the weather barrier, so the detail around it matters as much as the unit itself. Sealing and flashing decide whether water runs out and away or finds a path into the wall.
Openings are measured individually, units are set level and square, the perimeter is sealed and flashed, and both interior and exterior finishes are completed.

What you get
Measured to the actual opening
Openings in existing homes are rarely exactly square or consistent, so each is measured rather than assumed.
Flashed to shed water
Sealing and flashing are detailed so water is directed out and away from the wall assembly instead of finding a path in.
Finished inside and out
Interior trim and exterior finish are completed, so the installation is not left for someone else to tidy up.
