Glass patio sliders are the heaviest moving parts in most Florida homes — a single impact-glass panel can weigh well over 150 pounds. When the hardware under that weight begins to fail, the door drags, slams, bounces off the track, or refuses to latch. Ancient City Sliding Doors specializes in exactly these doors, safely removing heavy glass panels and rebuilding the hardware beneath them.
With 25 years of hands-on experience across St. Augustine, we've repaired every configuration: two-panel patio sliders, three- and four-panel walls of glass, pocket sliders that disappear into the wall, and heavy hurricane-impact systems on oceanfront condos.
Heavy Glass Requires the Right Equipment
Lifting a large glass panel out of its frame is the most dangerous part of any slider repair — done wrong, it risks shattered tempered glass and serious injury. We arrive with glass-handling suction cups, panel dollies, and a two-technician process for oversized panels, protecting your floors, your frame, and your glass throughout the repair.
Once the panel is out, we replace roller assemblies with tandem heavy-duty units rated for the panel's true weight, service the track, and rehang the door with the correct reveal so the glass carries evenly on both rollers.
Common Sliding Glass Door Problems We Solve
The calls we get most often: the door takes two hands to move, it derails when it hits a certain spot, the latch no longer catches, a grinding or popping noise comes from the bottom, water leaks in at the sill during storms, or the panel has visibly dropped on one side. Each symptom points to specific failed components, and each is repairable.
We also correct problems left behind by previous work — undersized rollers that wore out in a year, track cap installed over debris, or panels rehung out of square. A proper repair addresses the cause, not just the symptom.
When the Glass Itself Is the Problem
Fogged double-pane units, chips, cracks, and shattered panels are glass problems rather than hardware problems — and we handle those too. We measure the unit, order the correct tempered or impact-rated replacement glass, and install it in your existing frame, which costs far less than a new door.
If your door needs both hardware and glass work, we coordinate the whole job so it's completed in the fewest possible visits.
