GMB Overhead Door, LLC repairs and installs garage doors and openers, and it holds 5 stars from 34 Google ratings. A 2024 customer described Greg as the owner of GMB Overhead Door in Milford, CT. On its website the company says it services and repairs all brands of openers and also fully replaces existing units. Its BBB grade is A+. A recent customer says Greg walked them through a basic installation that worked as he said, rather than suggesting a paid service. A 2026 customer said Greg came out in less than an hour of the call and told them the garage door they had hit did not need to be replaced. In a 2024 review, a customer said Greg, the owner, opened their heavy two-car door so they could get their trapped cars out, took the broken spring with him to measure, and came back to replace the two 66-year-old springs and tune up the opener. A 2025 customer said Greg worked on a garage door install on an outbuilding where nothing was level, referred them to a carpenter he works with for structural prep, and got a standard-size door installed, which saved them money over a custom-size door. A 2024 customer said Greg returned their call without a message being left, walked them through opening the door, and later installed a new garage door and opener himself. A 2025 customer whose double-size door was jammed said the company fixed it quickly at a cost lower than expected. Connecticut lists its home improvement contractor registration, HIC.0671245, as active, held by GMB Overhead Door LLC.
Admittedly, I didn't use GMB for an install. However, Greg (Owner) was kind enough to walk me through a basic installation that worked perfectly, exactly as he said. He could have taken advantage and suggested that I need a paid service, but he took the high road. It is great to know that we still have honest, hard working companies in the town run by people with integrity. Thanks Greg
Extremely professional and knowledgeable. Greg where is through all options and came out as scheduled, finished up quickly, and was friendly throughout the entire process. He even checked up on our other door when he was here. Don’t look elsewhere. Forget the mailers and call Greg for no pressure honest solutions.
I accidentally hit my garage door because it wasn’t fully up!! Duh. Greg came out to my house in less than an hour of me calling … he let me know it would be a quick fix and my garage door did not need to be replaced. He could have told me I needed a new door but he was so honest. Great guy. GREAT COMPANY to work with … I highly recommend GMB, Overhead Door
Prompt, knowledgeable, professional. He explained all that he did and price was reasonable. I will use this company for all of my garage door needs.
Service was great, and very responsive to our needs. Greg showed his experience and knowledge of the issue right away. I would not call anyone else to fix my doors. I will tell ALL of my friends about this company and it's great service!!! Thank You for your continued support!
