Purchased 2 tilt doors over 20 years ago for my personal home build. 10 years later springs broke. We were advised that the mechanisms where too weak for the doors. So we paid (back then) $5,000 to replace the mechanisms. Springs broke again recently. They sent out a technician with the wrong springs. They came back a few days later with the right springs. They charged us for the call out and springs. We paid. Then they started chasing us for the first service call when they came out with the wrong springs and didn't do much. We paid, just to avoid potential debt collection and protect our credit rating. We will never use or recommend again. That's how you burn a 20 year old loyal client who has used you for 3 investment properties and own home in the Templestowe area over 20 years. Have a nice day.

Darren was great. He phoned just as he left his earlier job and also found a rather unwelcome visitor, nestled at the top of the roller door. A job now remove the possum & secure the area of entry. Unfortunately to allow him to stay will cost us a new motor

I originally was impressed. The salesman explained everything so I understood and the installer did a great job. About 12 months later I had a problem with my security door so I rang to ask how I could try and fix it or whether it was covered under the warranty. I was told it must be movement of the house (house is 12 years old so it’s not) or I pay $95 call out fee. If it’s not under warranty I just wanted to know (in layman’s terms) how to adjust. This experience put a real damper on the great one I had at time of purchase

Our experience of dealing with Eastern Garage Doors was brilliant. They are so easy to deal with... from the super enthusiastic Tom who visited and provided the quotation, to the lovely Georgia in the office who organized the installation date, to the team who came and put our new door in (and took the old door away). They were all efficient, knowledgeable, professional and polite. A real pleasure to deal with. We could not recommend Eastern Garage Door enough!

I got 4 quotes on my front gate controller and all the other companies didn't even bother coming and said I needed to buy an entire new gate system. John was great, he came to quote and spent a good half hour trying to determine the fault. After determining it was most likely the controller he quoted on replacing that first, before having to change the gate arms too (which would have been a new system). Controller worked and the cost was a quarter of the cost of a new system. It's refreshing to see that there are still good, honest tradesmen out there. Thanks John and the team at Eastern Garage Doors.

They are incredibly friendly and extremely knowledgeable about what they do, and their responses are impressively fast. Before finding this store, I had my garage door installed by another company, and I truly regret it. This company was able to fix even the garage door that was installed elsewhere and provided me with a perfect solution. They also identified the exact parts I needed. I highly recommend them.

DAVID KIM

06:45 26 Nov 25

Superb service! Darren and Tom have replaced our 20+ year old garage door mechanism with new state of the art Merlin opener plus new springs and cable. Totally worth it! Almost silent instead of terrible rattling and groaning noises, and they did the work in less time than they estimated and arrived early. Can’t ask for better service from these expert guys! Thanks gentlemen.

Another great experience with Eastern Garage Doors. Previously had a motor fixed promptly. This time, a spring randomly broke when we put the door down on Sunday night and upon calling the next day, we booked to get it fixed with in the next 24 hours. Joe who did the repair was punctual, friendly and finished in time for me to get to work. Thank you so much for a smooth and prompt repair, much appreciated ☺️

I was so very happy with the service provided by Eastern Garage Doors. My roller door had stopped working and I phoned a few companies only to be put on hold and not giving me a quote or any reassurance about fixing my problem. THEN I luckily phoned Eastern Garage Doors. I was pleasantly greeted with a lovely friendly voice ( Emily I think) who reassured me, gave me a quote and arranged Darren to come out within the hour. Darren arrived and explained what the problem was and fixed the door within 10 minutes.Darren was polite and efficient.Thank you Eastern Garage Doors.Happy CustomerMeg

Yesterday my garage door collapsed due to broken drum. Tried 4 places to get quotes, 2 responded immediately and friendly. Sent both very detailed photos of damages and gave measurements of door and drum diameters to avoid multiple trips hence cost. Eastern Garage was chosen for earlier attendance to repairs. Fixed this morning with minimum of fuss and was a clean job. Tradesmen friendly and not time wasting. Very highly recommended! Thank you Eastern Garage Door, Georgia and Tom.

we had an issue 2 weeks outside of the warranty. The problem was with the parts installed last year. When I called the immediate reponse was "well it is out of warranty so we will have to charge" not a good start. I was then told that I caused the problem, um how could the phone operator have any idea of this. Apparently her mind powers told her that I had disengaged the cable that hangs down. Not sure how this is even possible when I am outside of the garage, if only I had such abilities.The only positive is that they answer the phone quickly but we will never use this company again, support is 0/10ETA I think you missed the point of the review. Your workmanship failed 2 weeks post 12 mth warranty and you blame the customer, this is not a good review. It is great you are happy that you did not have to come and fix your work, that speaks volumes.

From the very get go eastern garage doors was thorough in coming up with the best solution. We have limited height clearance so Eastern garage was very honest and upfront about the options available to us. We settled on a custom clad tilt door which is a massive upgrade on what we had. The back and forth communication was prompt and clear. They did a similarly great job to a colleague who I've recommended them to. Will definitely recommend to others.

Booking in my garage door service was easy and booking staff were helpful and efficient. Very quick response time despite service staff being away due to illness. Cost of service was exactly as quoted and serviceman was knowledgeable and informative without being condescending. He arrived within allocated timeframe & notified me well in advance of arrival with exact arrival time. No pushy sales pitch just did as requested and was happy to provide answers to my questions after completing the service. I definitely recommend this company and will use them again in the future.

5 star for Louise's customer service. I needed to buy a new remote to troubleshoot why the garage door was only responding intermittently. Louise offered to take the price of the remote off the cost of installing the new garage opener, if I decide to go ahead with the new garage opener. She was very fast in responding to emails and was not pushy at all. Price quoted was very competitive, compared to 2 other quotes I got.Darren turned up on time to install the new garage opener. He also re-lubricated everything on the garage door.Highly recommend this business for their competitive pricing, high quality product and excellent customer service.

Our garage door motor began malfunctioning intermittently, prompting us to contact Eastern Garage Doors. They promptly scheduled an appointment for the installation of a new motor. Darren arrived on time and efficiently installed the new motor, which operates significantly quieter than our previous one. Reflecting on the experience, I wish we had reached out to them sooner. Overall, we are extremely satisfied with the outcome and highly recommend their services.

Excellent experience with Eastern Garage Doors & the team there. Professional can-do attitude whilst being highly professional. They managed to complete an excellent and clean install on my unique setup where many others weren’t willing to try / wanting to charge a fortune to even attempt. Eastern Garage doors came out and assessed it and ultimately built a perfect solution which works great. 100% recommend to anyone looking for a supplier & installer.

Chris Adams
