A suitable contractor can adjust and replace sliding door rollers, clean and repair tracks, and fix sliding screen and wardrobe doors. Glass goes to a glazier.
Sliding door roller replacement
A door that drags, jumps or needs two hands usually has worn rollers or grit in the track. Rollers are adjusted first. If they are cracked, flat or seized, the panel is lifted out of its frame and new matching rollers are fitted, then the door is rehung and levelled.
Rollers vary by door brand and frame. Tell us the door brand if you know it, and have a photo of the bottom corner of the door ready. The sliding door rollers guide covers what you can clean and adjust yourself first.
Sliding door track repair and cleaning
Sand and leaves packed into the bottom track stop the rollers turning. The track is vacuumed and the drain slots cleared, as aluminium door makers advise, and Stegbar recommends a light dry silicone spray on the clean track.
A door that catches at the same spot every time may have a dent or worn section in the track. A worn sill may need a track insert or a new sill section; that is assessed once the door has been looked at.
Sliding screen doors and wardrobe doors
Screen and wardrobe doors use smaller rollers and guides than patio doors.
Sliding screen door repair
Sliding flyscreen doors run on their own small rollers and top guides. A screen door that falls out of its track or won’t stay closed usually needs these adjusted or replaced to suit the door. Torn mesh can be included in the same quote request: see flyscreen repairs. Security screen doors are not part of this service.
Sliding wardrobe door repair
Wardrobe doors use smaller rollers and guides than patio doors. Note the wardrobe brand and how many doors stick or jump off their track.
Broken glass goes to a glazier
Roller and track work is a hardware repair on an existing door. Cracked or broken glass, a new glass panel or a replacement door frame is a glazier’s trade (NSW requires a contractor licence for glazing jobs over $5,000). Keep clear of damaged glass and call a glazier.
In a unit block, the balcony door is usually common property, so owners should ask the strata manager first and tenants their landlord. The sliding door rollers guide explains the strata rules.
What changes the cost?
The rollers your door takes, the number of panels and the condition of the track affect the price. A heavy glass patio door takes two people to lift out.
Airtasker publishes $140–$213 (median $187) as the average cost of sliding door repair in Sydney (page last updated 7 October 2026; unit and GST not stated). That is a marketplace figure, not a quote. The sliding door rollers guide lists other published roller prices.
See the handyman cost guide for published hourly rates and task prices, and what to check in your quote.
This service covers minor, non-structural work. Residential building jobs are limited to $5,000 in total, including labour, materials and GST. Electrical, plumbing, gas and other specialist trades are outside this service. The limit applies to the whole job; work cannot be split into smaller invoices to avoid licensing. NSW licensing rules.
What to have ready
- Which door: patio, balcony, screen or wardrobe, and how many panels
- What happens when you slide it: drags, jumps, catches at one spot
- A photo of the bottom corner of the door and the door brand if known
- Whether it is a house, a strata unit or a rental
Have close-up photos and a wider view ready. Describe the job in the form; photographs cannot be uploaded here.
For a rented home, report repairs to the landlord or agent first. Alterations are different from repairing existing damage and may need specific written permission. See the NSW rental repairs guide before making a booking on someone else’s behalf. Moving out? Use the end-of-lease repairs checklist.
Sliding door repairs questions
Can you replace sliding door rollers?
Yes, where matching rollers are available for the door. The panel is lifted out, the old rollers swapped and the door rehung and adjusted.
Can you fix a sliding door track?
A dirty track can be cleaned and its drain slots cleared. A worn or damaged sill may need a track insert or a new sill section, which is assessed once the door has been looked at.
Can you replace the glass in a sliding door?
No. Cracked or broken glass is a glazier’s job and is outside this service.
How much will the job cost?
The quote depends on the items, condition, parts and access. A suitable contractor can agree the work and price before starting. The cost guide gives third-party benchmarks; those are not quotes from this website.
