Three ways the right door transforms a room.
Light & views
Floor-to-ceiling glass floods the room with daylight and unobstructed views of the yard.
Sealed tight
A precise seal keeps heat, weather and noise out — lower bills, quieter rooms, year-round.
Smooth & secure
Effortless glide every time, with secure transitions that lock up solid when closed.

Three signs your patio door is failing.
It drags or won't glide
A door that’s hard to open and close has worn rollers or a frame that’s shifted — and it’s only getting harder.
Air through the gaps
Drafts around the frame and climbing energy bills mean the seal has given out and your HVAC is working overtime.
Cracks & warping
Visible cracks or warping look tired and compromise both the security and insulation of your home.
Three steps, start to finish.
1. Measure & quote
We assess the opening, recommend the right style and series for your space, take exact measurements, and quote it.
2. Remove & set frame
Out with the old door and frame. We level for uneven floors, check the wall structure, and set the new frame square.
3. Hang, seal & test
Panels hung and adjusted for a tight glide, weatherstripped and sealed against leaks, then tested before we clean up.
The hard parts, handled.
Big glass openings are unforgiving. Our old-world craftsmanship is in the details most installers miss.
Uneven floors
We measure the floor before we start and shim precisely, so panels align and glide true instead of binding.
Wall structure
Wide doors are heavy. We confirm the wall can carry the load before cutting — no sagging, no cracks later.
Proper sealing
High-quality weatherstripping and sealant stop air and water intrusion where cheap installs fail.
Protected, twice over.
Your Milgard doors carry an industry-leading Full Lifetime Warranty — and Greco Roman stands behind every install with professional care at minimal cost.
Decades of door experience, old-world craftsmanship, and only the highest-quality materials. That’s the difference.
