What Jamul Homeowners Say About Mainspring Garage Door Co.
We’ve been working on garage doors in Jamul since 1984, and we don’t take a single review for granted. Every call that comes in gets answered by a live person, our technicians show up in uniform with the parts already on the truck, and we put the 90-Day Done Right Promise in writing on every single job. The feedback below comes from real neighbors, in real Jamul neighborhoods, who called us with real problems and got them fixed without any runaround.

Our Clopay door snapped a spring on a Saturday morning and the car was trapped inside. I called at 7:15, got a live person immediately, and Carl’s technician was out to our place near Lawson Valley Road by noon. He had the right torsion springs on the truck, swapped both sides, and the price he quoted on the phone was exactly what I paid. No surprises on the bill.

We bought an older home off Jamacha Boulevard with a Genie opener that sounded like a tractor and reversed every time it hit the bottom of the track. I had two other companies out for estimates, then called Mainspring for their free second opinion. Carl pointed out the rail was actually bent from a previous DIY install, not the opener itself. Fixed the rail, realigned the safety sensors, and saved us from buying hardware we didn’t need.

The cable on our Wayne Dalton door frayed through and wrapped around the drum after a windy week last March. I was worried about the door dropping, so I didn’t touch it. The technician walked me through why it’s dangerous to mess with cables under tension, then had the new cable set and the door balanced in about an hour. He even checked the other door while he was here and caught a worn roller we hadn’t noticed.

We needed a full door replacement on our rental property near Steele Canyon. Carl came out himself for the measure, brought sample sections from Amarr and Clopay so the tenant could pick the color, and the install crew showed up exactly when he said they would. The old door came down, the new one went up, and they hauled everything away. I got the 90-Day Done Right Promise in writing before they left. That’s a square deal.

My LiftMaster opener started clicking but wouldn’t lift the door more than six inches. I figured the motor was shot. The Mainspring tech checked it and found the trolley had stripped from years of running a door that was out of balance. He replaced the trolley, adjusted the spring tension so the opener wasn’t doing all the work, and now it runs quiet for the first time since we moved in. He could have sold me a new opener and I wouldn’t have known better.

After a heavy rain in January, our garage floor was wet and the bottom seal on the door had rotted through. I called thinking I needed a whole new door. Karen from the office scheduled me for the $89 Seasonal Tune-Up, and the technician replaced the seal, lubed the hinges, and adjusted the travel limits so the door actually seated against the new rubber. Took about 90 minutes. I’m a senior, so the 5% discount applied too. They didn’t try to upsell me once.
