Should I repair or replace my sliding glass door?
The honest answer surprises most people: the door is usually fine. It's the hardware that failed — and hardware is a repair.

The core truth
Most 'broken' sliding doors have a small failed part, not a failed door. A heavy door, an off-track panel, a door that won't lock — these are roller, track, and lock repairs. The frame and glass, the expensive parts, are typically fine.
Repair makes sense when
- The door drags, grinds, is off the track, or won't lock (hardware issues).
- The frame is solid, even if it needs resealing or new weatherstripping.
- Only one pane's seal has failed (replace the glass, keep the door).
Replacement makes sense when
- The frame is corroded through structurally.
- Insulated glass has failed across several panels.
- The door has been repaired repeatedly and keeps failing.
- You're upgrading to impact-rated doors for storm protection.
The cost gap
A roller or lock repair is a small fraction of a full door replacement. Even glass replacement usually reuses the frame. We only recommend replacement when it's genuinely the better value.
How we help you decide
We inspect the door, tell you exactly what failed, and give you both options honestly when it's a close call — with a clear estimate for each. No pressure toward the expensive path.
