You get a price before we start. It does not change when the truck arrives.
Meet the Fair Oaks Ranch Team Behind Mainspring Garage Door Co.
We’re the crew that shows up when your garage door won’t budge at 6 a.m. or when you’re staring at a broken spring and wondering if you’ll make it to work. Every person on this team lives within 30 minutes of Fair Oaks Ranch, and we all answer to the same standard: fix it right, say what it costs before we start, and stand behind it if something’s off. No phone trees, no subcontract crews, no surprises on the bill.
Our People
Carl Dutton, Owner
I started this company in 1984, back when Fair Oaks Ranch was mostly ranch land and a few early subdivisions. The name Mainspring comes from the coiled spring that carries a door’s full weight - one part fails, the whole system stops. That still describes how I think about this business. I’m on the phone most mornings, still drive to jobs when we’re stacked up, and I sign off on every 90-Day Done Right Promise in writing. My wife says I talk about torsion springs at dinner. She’s not wrong.
Mike R., Lead Technician
Mike’s been with us 14 years and can diagnose a failing opener by sound alone. He’s factory-certified on LiftMaster, Chamberlain, and Genie systems, and he’s the one we send when a customer has already had two other companies out and the door still isn’t right. Mike keeps a notebook of every oddball repair he’s seen - pinned spring brackets in Sendera Ranch, custom wood doors in Anaqua Springs that warped in the Hill Country humidity. Off the clock, he restores vintage motorcycles and applies the same patience to a 1972 Honda that he does to a seized torsion tube.
Doris V., Senior Installer
Doris joined us in 2016 after ten years in commercial door systems, and she handles our new installations and full replacements. She’s particularly sharp on Clopay and Amarr door lines, and she’s trained three of our apprentices through the K.E.Y.S. program. Doris measures twice, explains the quote once, and won’t let a job leave until she’s tested the balance and photo-eye alignment herself. She lives in Boerne and knows which way the afternoon sun hits Fair Oaks Ranch garages, so she can warn you when a dark-colored door will absorb too much heat and stress the opener.
James T., Service Coordinator
James is the live voice that answers when you call (830) 241-0934 at 11 p.m. on a Sunday. He’s been with Mainspring since 2019 and knows which technician is closest to your neighborhood, which trucks carry which parts, and whether your description of “a loud bang and now the door’s crooked” means a snapped cable or a broken spring. James schedules, dispatches, and follows up on every job. He also tracks our standing offers - the $50 off repairs over $250, the $89 Seasonal Tune-Up, the senior and veteran discount - so the price you hear on the phone matches the price on the invoice. He fishes the Guadalupe when it’s running clear and will ask you about your weekend if you have time to talk.
Elena M., Apprentice Technician
Elena started with us in 2023 after completing her mechanical certification at Northwest Vista. She’s working her way through the K.E.Y.S. journeyman program under Mike’s supervision and has already handled solo cable replacements and roller swaps across Fair Oaks Ranch and Helotes. She’s particularly good at explaining what’s wrong to homeowners who want to understand their own system. Elena’s first language is Spanish, which has helped us serve more families in the area without relying on translation apps that garble technical terms. She runs trail races on Saturdays and claims the Hill Country hills are easier than a heavy 16×7 insulated door on a high-lift track.
One Standard, Every Job
Every person on this page answers to the same agreement, written on every invoice: the 90-Day Done Right Promise. If we install a new opener and the belt slips, we come back. If a spring we replaced doesn’t sit right in its cones, we fix it. No paperwork to file, no manager to escalate, no argument about whether it was “working when we left.” We said we’d stand behind it, and we do.
The trucks leave our shop stocked with torsion springs, extension springs, cables, rollers, hinges, and openers from the brands we service - LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, Raynor. Most days, that means one trip, one fix, one flat price stated before any work starts. The technician who shows up at your door in Fair Oaks Ranch will be background-checked, uniformed, and trained under the same code: Krafted right, Every time, Your home first, Standing behind it.
We’ve been at this since 1984. The phones still ring to a live person, 24/7, including nights, weekends, and holidays. We’ll be there when we say.
