50 times a day

Hollow, sticking, builder-grade doors quietly cheapen good homes. Solid, properly hung doors with quality hardware change how a house feels in the hand.

We fit doors to openings that are rarely square, upgrade windows for light and efficiency, and cut new openings, including legal egress windows, with engineering and permits handled.

  • Solid-core and custom doors
  • Barn doors and pocket doors
  • Window replacement and enlargement
  • Quality hardware, properly hung

Frequently asked questions

Don't see yours? Call us, we're happy to help.

Can you enlarge my basement windows?

Yes, including cutting concrete for legal egress windows with engineering, permits and proper wells. See our egress windows service.

Do you install barn doors?

Yes, with proper backing and soft-close hardware so they run smooth and quiet for years.

What is the benefit of solid-core doors?

Weight, sound blocking and durability. They are the single fastest upgrade in how a home feels.

Do you replace exterior windows too?

As part of renovations, yes: window replacements and enlargements with efficient modern units.
