Patio Door Adjustment & Alignment Montreal Glides Like New
Your sliding door rubs against the frame, no longer closes properly, or requires excessive force? In 80% of cases, a simple professional adjustment of the rails, strikes, and rollers is enough to restore smooth, silent operation. Avoid a costly replacement!
Is your door not sliding properly? Identify the issue:
Door rubbing against the frame
You see scuff marks on the frame or door itself? The horizontal alignment is unbalanced.
Door tilting or sagging
The door tilts forward or backward while sliding? Roller heights are no longer synchronized.
Abnormal gap between panels
A gap too wide or too narrow between double-door panels? The strikes or stops are misaligned.
Abnormal force required
You have to push hard even with new rollers? The track is likely warped or clogged.
Why do sliding doors go out of alignment?
Sliding doors are precision mechanical systems where every millimeter matters. Over time, vibrations, temperature swings, roller wear, and impacts (especially from children or pets hitting the door) gradually knock alignment off.
Floor settling, typical in older Montreal homes, also changes the angle of the bottom track. A slightly misaligned door rubs, prematurely wears rollers and frame, and eventually jams. Early adjustment preserves your door for years.

Our technician performs a complete 15-minute diagnosis: track level, roller heights, strike alignment, stop condition, and threshold check. He uses laser levels for precision alignment within 0.5 mm.
