We just wrapped up a new deck for a homeowner looking for a durable, low‑maintenance upgrade. Strong framing, tight lines, and a finish built to last. Another project done the Legan way.

Most big-box companies push double‑pane patio doors at premium pricing.
We install triple‑pane — better efficiency, better comfort — for less than their double‑pane quotes.

Go local. Go Legan.

Another transformation in the books.
We took this aging deck and outdated patio door and turned them into a clean, modern, high‑efficiency setup built to last. The new structure is solid, the finish is sharp, and the upgraded door brings in a ton of natural light.

If you’re thinking about refreshing your outdoor space, we’d be proud to help.
