Sliding Door Repairs
How much does it cost to repair a sliding glass door?
Depending on the replacement parts needed for a standard size sliding door (H2100 W1200), you’re looking at a price range of $180–200.
How do you fix a sliding door that won't slide?
The sliding panel uses a pair of rollers to slide on a track in the bottom channel.
Does homeowners insurance cover a broken sliding glass door?
No. A sliding door that does not slide requires general maintenance, which is not covered under home insurance. Glass breakage is generally covered, but check your excess.
What is the best way to lubricate a sliding glass door?
Most modern rollers have a nylon tyre surrounding a sealed bearing system. If rollers are no longer turning, replacement is usually required.

Yes, as long as it’s silicone-based. Standard WD-40 attracts dust and turns into thick residue.

Noise is usually caused by worn weather felts, allowing metal surfaces to rub. Replacing felts resolves this.

Vacuum the bottom channel, then wipe the track using wax and grease solvent. Light sanding may be required if damaged.
