How do I know if the rollers are the problem?

Watch the bottom of the panel as it moves. If it grinds, rides low or catches in the same spots even after the track is cleaned, the rollers are the likely cause. A gap at the latch side points the same way. A pro confirms it by lifting the panel out.

Why won't my patio slider lock anymore?

Usually the panel has dropped on worn rollers and the latch hook sits below its keeper. Raising the rollers is often all it takes. If the latch is loose, cracked or spins freely, the lock needs replacing, a small and common job.

When is a slider worth fixing rather than replacing?

In most cases. Rollers, the track, latches, handles, weatherstrip and even the glass can each be replaced on their own, with far less disruption than a new door. Replacement makes sense when the frame or sill is rotted, cracked or twisted, because new parts won't fix that.

What changes the price of a sliding door repair?

The part being replaced, whether it's stock or has to be matched for an older door, the panel's size and weight, the state of the track, and access, such as an upper-floor balcony. Glass is quoted separately. A short video of the door moving helps a pro quote before visiting.

Make your sliding patio door glide again

A patio door that grinds, lifts off its track or won't lock is usually telling you about one worn part. Rollers, the track, a latch or a handle can each be fixed on their own, and one roller is a real job. We connect you with an independent local pro who repairs sliders. If the frame is past saving, they'll say so.

Grit and wear on the bottom track: the first place a pro looks.

Troubleshooting

Why sliders stop sliding: worn rollers, bent or dirty track, sagging panel

Start with what the door is doing. If it's the screen jumping the track, not the glass panel, see screen door repair.

Won't slide, or grinds as it moves

Flattened or seized rollers, or a track packed with grit. Cleaning buys time; worn rollers need replacing.

Comes off the track or lifts out

A bent track lip, a dropped roller, or a panel set back unevenly. Don't force it; a loose panel is heavy and can fall.

Won't close all the way

Worn rollers let the panel sink and meet the jamb at an angle. Daylight down the latch side is the giveaway.

Won't lock or latch

The panel has dropped so the hook misses its keeper, or the lock has worn out.

The repair

Roller and track repair, step by step

Here's what the pro we match you with usually does.

Lift the panel out
The moving panel comes off the track, and the pro checks the rollers, bottom rail and frame corners.
Clean and true the track
Grit comes out, and a bent lip is straightened or capped.
Fit matching rollers
Rollers differ by door, so the old ones are matched by size and housing.
Adjust and test
The rollers are set so the panel runs level and the latch meets its keeper.

Handles and locks

Handles, locks and security bars

On a ground-floor rental, a slider that won't lock matters. It's usually alignment.

Latch out of line

When the panel drops, the hook sits below its keeper. Raising the rollers often fixes it with no new parts.

Worn lock or handle

The pro matches the hole spacing so a new set fits the existing cut-outs.

Security bar or foot lock

A track bar or foot lock adds a second stop on rental sliders.

A latch hook catching its keeper, beside one too low to reach it — Aligned, and dropped below the keeper as the rollers wore.

Past repair

When the frame is too far gone

Rollers are the small end of a patio door; the frame is not. A pro will suggest a new door when the sill is cracked or soft and letting water in, or the frame has twisted so the panels won't meet.

Then read patio door replacement. For front, storm and screen doors, the doors and screens overview sorts problems by symptom.

Glass in the door

Fogged or cracked glass in a patio door

Fog between the panes means the sealed unit's seal has failed, even if the door slides perfectly. A crack is a glass job too. Either way, the glass can usually be replaced while the frame stays. Ontario's building code calls for tempered or laminated safety glass in sliding doors (OBC 9.6.1.4), and each unit is made to size. Fog that wipes off the room side is condensation; the foggy window page explains.

Condos and rentals

Balcony sliders in condos and apartments

Plenty of Durham sliders open onto a balcony; Pickering has the region's highest share of condos.

Before replacing a balcony door or its glass, check who looks after it: condo owners, the declaration and property manager; tenants, the landlord. Oshawa's same-size permit exemption covers houses only, so check with the City. Property managers can send several doors as one request.
