What makes us unique
A WHOLE NEW LEVEL OF OPEN CONCEPT
As a Glass Expanse dealer, Milestone Windows & Doors brings this American-made system to homeowners, builders, and remodelers across Greater Houston, along with the same honest, family-owned service we’ve offered for the past 10 years.
WHY HOMEOWNERS CHOOSE SLIDE-AND-STACK
Less Frame, More View
Only 2.25″ of frame between closed panels, among the slimmest in the industry, so the view does the talking.
A Track You’ll Barely Notice
A 1.75″ lower track creates a smooth transition between rooms and patio. In some configurations, it can sit flush with your interior floor.
Flexible Panel Positions
Open, closed, or “flexed.” Independent panels let you open as few or as many as you want, or space them out for airflow without opening the whole wall.
Effortless, One-Hand Operation
You only ever move one panel at a time, so even a 40-foot opening stays light and easy to use.
Top-Hung for Smooth Gliding
The system hangs from the top. Lower wheels float in the track, so dust and debris won’t wear them down or cause sticking.
Made in the USA, Backed for 10 Years
Designed and built in Texas by Glass Expanse’s in-house team and covered by a 10-year warranty.
