How to Spot Quality Craftsmanship in Window and Door Installation

Look Closely At The Fit Before You Judge The Finish

The first signs of craftsmanship show up in the rough opening and the fit. A properly installed window or door should look centered, sit level, and feel solid before the trim ever hides the edges.

One of the easiest things to miss is alignment. A sash that drifts, a door that swings open on its own, or a lock that needs to be forced usually points to more than a minor annoyance. Those are often signs that the installer rushed the setup or did not correct the opening before fastening the unit in place.

An experienced window and door installation company can confirm whether the unit is seated correctly with a quick inspection.

What The Finished Work Should Look And Feel Like

Performance Is The Real Proof

Good craftsmanship should be visible months later, not just on installation day. If a window or door starts to draft, stick, or collect moisture shortly after the job is done, something in the setup was missed.

• What is your process for flashing and sealing?
