The Mainspring Garage Door Co. Guarantee

When we say we stand behind our work in Shavano Park, we mean it in writing. Every job we complete carries the 90-Day Done Right Promise: if something isn’t right, we come back and make it right. No paperwork to file, no dispute process, no arguing about whose fault it is. Carl Dutton, Owner of Mainspring Garage Door Co., put this in place because a guarantee you have to fight for isn’t a guarantee at all. Since 1984, we’ve served this area for over 42 years, and we’ve learned that homeowners remember how you handle the problem long after they forget the original repair. That’s why our technicians arrive in uniform, background-checked, and trained under our K.E.Y.S. values code - Krafted right, Every time, Your home first, Standing behind it. The price we quote is the price on the bill. No surprises.

What’s Covered

  • Workmanship on every repair and installation. If a spring we installed shifts, a cable we replaced frays early, or an opener we mounted develops a problem related to our work, we return and fix it at no charge within the 90-day period.
  • Parts we supply and install. We carry springs, cables, rollers, hinges, and openers from major brands including LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor - and we stand behind the fit and function of every part we put on your door.
  • Job site cleanup and protection. Our technicians lay down protective coverings, collect debris, and leave your garage as clean as we found it. If we don’t, call us and we’ll return to finish the job properly.
  • On-time arrival commitment. We will be there when we say. If traffic or weather delays us in Shavano Park or the surrounding communities, we call ahead with a real ETA, not a window that stretches for hours.
  • Honest, upfront pricing with no surprises on the bill. The flat price is stated before any work begins. You’ll know exactly what you’re paying for, and you’ll approve it in writing before we start. That’s a square deal.

Our Satisfaction Promise

If you’re not satisfied with our work, we want to know. Here’s what happens: you call (830) 224-4217, and a live person answers - 24/7, including nights, weekends, and holidays. No phone trees, no voicemail, no after-hours answering service. You explain what isn’t right. We schedule a return visit at no charge, and we fix it. The 90-Day Done Right Promise is stated in writing on every job, so there’s nothing to negotiate. Carl Dutton has run Mainspring Garage Door Co. since 1984 on a simple principle: if we touched it last, we own the result. We’ve had homeowners in Shavano Park call us six weeks after a repair because a roller started making noise again. We came back, diagnosed it, and handled it. That’s the difference between a company that says it stands behind its work and one that actually does. We don’t believe in making you prove we made a mistake. If you’re not happy, we’re not done.

Licensed & Insured Backing

Anyone can print a guarantee on a website. The real protection comes from who’s standing behind it. Mainspring Garage Door Co. is licensed and insured, which means if the unexpected happens - property damage, technician injury, a rare installation complication - you’re not left holding the bill or dealing with your homeowner’s insurance. In Shavano Park, where many homes feature custom garage door setups and high-end finishes, that matters. Our insurance and bonding exist so a bad day doesn’t become your financial problem. We’ve been serving local communities for over 42 years, and we’ve maintained our coverage without lapse because we plan to be here for the next 42. When Carl Dutton sends a technician to your home, that person arrives as a representative of a company with real assets, real history, and real accountability. The 90-Day Done Right Promise is backed by more than good intentions. It’s backed by a business that has survived four decades because it does what it says.

How Our Guarantee Compares to Typical Warranties

Most garage door companies in the Shavano Park area offer some form of warranty, but the details matter. A “limited warranty” often means you fill out a form, wait for approval, and argue about whether the failure was due to workmanship or “normal wear.” Our 90-Day Done Right Promise removes that friction. If we did the work and something related to it isn’t functioning properly, we return. No claim number, no third-party administrator, no exclusion list in fine print.

Manufacturer warranties on parts - from brands like LiftMaster, Chamberlain, or Clopay - cover defects in the part itself, but they don’t cover the labor to diagnose, remove, and replace that part. Our promise covers our labor. So if a Genie opener motor fails under manufacturer warranty in month two, we’ll handle the swap under our workmanship coverage. You don’t pay twice for the same problem.

What We Ask of You

A guarantee works both ways. To keep your coverage valid, we ask that you operate the door according to manufacturer guidelines and report unusual noises, slow operation, or balance issues promptly. A grinding roller or a door that drifts closed is often a cheap fix today and an expensive repair next month. We saw this last spring in the Shavano Park area after a period of heavy humidity - homeowners who ignored slight sagging in their cables ended up with full spring failures. Call us at (830) 224-4217 when you first notice something off. Our $89 Seasonal Tune-Up catches most of these issues before they become emergency calls.

Standing Offers That Don’t Disappear

Our guarantee sits alongside permanent offers, not rotating promotions designed to create false urgency. Current standing offers include: $50 off any repair over $250, a free second opinion on any written estimate from another company, the $89 Seasonal Tune-Up, and a permanent 5% discount for seniors and veterans. These don’t expire because they’re part of how we do business, not a tactic to get you to call today before a deadline. We believe a square deal shouldn’t require a countdown timer.

Why We Named the Company Mainspring

The mainspring is the component that carries the entire weight of a garage door - typically hundreds of pounds of steel, wood, or aluminum balanced on a coiled spring under extreme tension. When it fails, nothing else works. We chose the name because that’s how we see our role in Shavano Park homes. The garage door is the largest moving part of most houses. It’s your family’s primary entry point, your vehicle’s protection, and a significant factor in your home’s curb appeal and energy efficiency. When it works, you don’t think about it. When it doesn’t, you need someone who treats it with the seriousness it deserves. That’s the standard Carl Dutton has maintained since 1984.
