About QRS
Built for real jobs, not showrooms.
QRS works the way jobs actually run: plans, takeoffs, rough openings, schedules, and deadlines that don't move.
Some orders are simple. Some need custom sizing, special glass, fire ratings, or a different product line altogether. Either way you get a straight answer about the right material, and then we supply it.
Schedules, takeoffs, and rough openings reviewed before anything gets priced.
Tempered glass, egress, fire ratings, handing. Caught on paper, where they're free to fix.
Oversized, arched, historic, high-end. We find the right product instead of forcing the wrong one.

If it fills an opening, we supply it.

Why QRS
Why contractors keep our number.
Contractors call us because we make the hard parts easier. From choosing the right product to working around tight schedules, unusual openings, and real-world budgets, we give clear answers and help keep the job moving.
Start a projectStraight answers
What's standard, what's custom, and what's a bad idea. We tell you before you order, not after the truck leaves.
The right source for the budget
Builder-grade to premium, quoted from suppliers we'd trust on our own jobs. No forcing one product line onto every project.
We speak schedule
Rough openings, handing, egress, lead times. You won't spend twenty minutes explaining your job to someone who's never seen one.
Odd openings welcome
Oversized, arched, historic, fire-rated. When standard won't cut it, we go find what will.
Community impact
Giving back is part of how QRS does business.
We share a portion of our profits with local organizations that are making a real difference in the communities around us. By supporting the people and groups working closest to home, every project we complete helps contribute to something bigger than the work itself.
