GEM Garage Doors
Customers routinely arrive after being quoted thousands elsewhere — and leave with a repaired door instead.
Shannon is the standout technician by name: praised for arriving on weekends, solving problems competitors dismissed as unfixable, and taking time to explain what he's done. Two reviews do flag a breakdown in follow-through — one customer couldn't get a call-back after three attempts over two weeks, and another was stood up on a booked morning visit — so if you're booking around a tight window, it's worth confirming the appointment the day before and getting a direct contact number rather than relying on the general line.

About GEM Garage Doors
GEM Garage Doors specialises in repairs, motor installations, and full door replacements — and what sets them apart is a genuine willingness to troubleshoot over the phone before sending anyone out, which has saved customers from unnecessary call-out fees and inflated quotes. Shannon is the name that appears most across repairs: customers credit him specifically with diagnosing faults correctly when others couldn't, reprogramming doors to improve clearance that competitors said was impossible, and arriving on weekends to secure homes when a door fails at the wrong time. Rob handles gate and motor work alongside Shannon, and the broader team — Andrew, Dave, Corey, and Tom are all mentioned by name — suggests GEM operates with a crew large enough to cover urgent jobs quickly without relying on a single technician. Their approach to quoting is notably different from competitors: multiple reviewers came to GEM after being told they needed a full replacement, only to have their existing door repaired for a fraction of the cost. They stock genuine remote controls, install Merlin motors, and work across roller doors, panel lift doors, and motorised aluminium doors — covering new installs, broken cables, spring replacements, track resets, and servicing. With over two decades operating out of Brookvale, they're a practical first call for Northern Beaches homeowners dealing with anything from a door off its track to a full new motorised setup.
Best for: urgent same-day repairs when a door won't close or has come off its track, homeowners who've been told they need a full replacement and want a second opinion, and motor or remote control upgrades on existing doors.

Does GEM Garage Doors offer emergency or same-day callouts?+
Yes — same-day response is a recurring theme across their reviews. Multiple customers describe GEM arriving within an hour of calling, including on weekends, when their garage door wouldn't close and they couldn't secure their home. Shannon in particular is noted for weekend attendance. That said, demand may affect availability, so calling directly rather than leaving a message gives you the fastest response.
What areas does GEM Garage Doors cover?+
They're based in Brookvale on Sydney's Northern Beaches. Reviews don't specify exact travel boundaries, so if you're outside the immediate Northern Beaches area, it's worth confirming coverage when you call. Their years of local operation suggest a well-established service area across the Northern Beaches corridor.
Will GEM try to fix my existing door before recommending a replacement?+
Based on several reviews, yes — this is one of the things customers specifically praise them for. Multiple reviewers came to GEM after being quoted $6,000–$7,000 for a full replacement elsewhere, only to have their door repaired at a fraction of that cost. GEM also offers phone-based triage before dispatching a technician, which has helped customers avoid unnecessary call-outs entirely.
Which technicians are likely to handle my job, and what are they known for?+
Shannon is the most frequently mentioned technician and is praised for fault diagnosis, weekend availability, and solving problems other companies said were impossible — including reprogramming a door for better clearance after competitors said it couldn't be done. Rob is mentioned for gate and motor work. Dave, Andrew, Corey, and Tom also appear across installation and repair reviews, suggesting a team large enough to handle multiple jobs concurrently.
How is GEM's pricing compared to other garage door companies?+
Reviewers consistently describe GEM's pricing as fair or better than competitors, with specific mentions of good value on spring replacements, remote controls, and motor installations. Several customers note being pleasantly surprised after getting much higher quotes elsewhere. GEM doesn't appear to publish fixed pricing online, so getting a quote upfront is still recommended — particularly for full door replacements or motor upgrades.
