Questions homeowners ask
Why do older patio doors get so hard to slide?
Dirt, pet hair, and Colorado road grit wear down cheap plastic rollers, causing the door frame to drag on the aluminum track. Quality replacements use sealed stainless steel ball-bearing rollers.
Are modern glass patio doors safe against break-ins?
Yes. Modern doors feature heavy tempered safety glass and multi-point locking mechanisms that hook into the steel-reinforced jamb at multiple vertical points.
