Our Guarantee & Warranty - Mainspring Garage Door Co.

The Mainspring Garage Door Co. Guarantee

When we say we stand behind our work in Alamo Heights, we mean it in writing. Every job we complete, whether it’s a spring replacement on a 1970s ranch in Terrell Hills or a new opener install near the Quarry, is backed by our 90-Day Done Right Promise. If something isn’t right, we make it right. No paperwork to file, no dispute process, no arguing about whose fault it is. We show up, we fix it, and we don’t charge you again. That’s been our way since Carl Dutton founded this company in 1984, and it’s not changing.

Call (830) 364-5701

We didn’t name the company Mainspring by accident. The mainspring is the part that carries the entire weight of your door, every time it goes up and down. When it fails, everything stops. We think of our guarantee the same way: it’s the essential foundation that holds up everything else we do. Without it, the rest is just talk.

What’s Covered

• Workmanship on every repair and installation. Our technicians are trained as journeymen under our K.E.Y.S. values code, and we don’t consider a job finished until it meets the standard we’d hold for our own homes in Alamo Heights.
• Parts we supply and install. We carry springs, cables, rollers, hinges, and openers from all major brands on every truck, so most repairs are completed in a single visit with no waiting on parts and no second trip.
• Cleanup and respect for your property. Our technicians arrive in uniform, background-checked, and ready to work. When we’re done, we haul away the old parts and leave your garage as clean as we found it.
• On-time arrival and clear communication. We will be there when we say. If we’re running behind, you’ll know before you have to wonder. No four-hour windows that stretch into six.
• Honest, upfront pricing with no surprises on the bill. The flat price is stated before any work begins. You agree to it. We do the work. That’s the deal. The number on the invoice matches the number you approved, period.

Our Satisfaction Promise

Here’s what happens if you’re not satisfied with our work in Alamo Heights. You call us. A live person answers, 24 hours a day, including nights, weekends, and holidays. No phone tree, no voicemail, no after-hours answering service. You tell us what happened. We schedule a return visit at no charge. Our technician arrives, assesses the situation, and fixes what’s wrong. You don’t pay again. You don’t fill out a claim form. You don’t wait for a manager to call you back.

The 90-Day Done Right Promise is stated in writing on every job. We put it on the invoice because we want you to have it in your hands, not buried in fine print on a website. If a spring we installed develops a squeak after three weeks, we come back. If an opener we programmed starts acting up, we come back. If a cable we replaced doesn’t sit quite right, we come back. We’ve been doing this since 1984, and we’ve learned that the only way to build a reputation in a community like Alamo Heights is to handle the problems before they become disputes.

Carl Dutton has always said that a guarantee isn’t worth anything if you make the customer fight to use it. That’s why we stripped out the paperwork. That’s why there’s no “warranty department” to transfer you to. The technician who did the work, or another journeyman from our team, returns and makes it right. It’s that simple.

Licensed & Insured Backing

The 90-Day Done Right Promise sits on top of something more fundamental: we’re licensed and insured, and we’ve been since 1984. That paperwork matters. It means if something goes seriously wrong, a rare event but one we’ve seen happen in this trade, you’re not left holding the bag. It means our technicians are covered while they’re working on your property. It means if a ladder bumps your car or a tool damages your garage interior, there’s a real policy behind us, not just a handshake and a hope.

We’ve watched too many homeowners in Alamo Heights learn the hard way what happens when they hire an unlicensed operator for garage door work. Torsion springs store massive energy. A door that weighs 150 pounds can come down fast if the wrong person touches it. Our licensing isn’t just a bureaucratic checkbox. It’s proof that we’ve met the standards, that we carry the coverage, and that we’ll still be here tomorrow if you need us. After 42 years serving local communities, we plan to be here for decades more.

Standing Offers That Never Disappear

We don’t believe in bait-and-switch promotions that expire Friday at midnight. Our standing offers are always available because they’re built into how we do business:

• $50 off any repair over $250. Straight discount, no games.
• Free second opinion on any written estimate. Bring us a competitor’s quote. We’ll tell you honestly if it’s fair or if something’s off.
• $89 seasonal tune-up. Catch problems before they strand you.
• Permanent 5% discount for seniors and veterans. No expiration, no cap.

What We Ask of You

A guarantee only works when both sides keep their word. We ask that you describe the problem honestly when you call, that you clear vehicles and storage from the work area before we arrive, and that you point out anything that doesn’t look right before we leave. If you notice a noise or a wobble two days after we’re gone, call us. The 90-Day Done Right Promise is still active, and we’d rather fix it early than let it become a bigger problem.

How to Reach Us

Call (830) 364-5701 any time. A live person will answer. We’ll schedule your service, confirm your upfront price, and stand behind the work when we’re done. That’s the Mainspring way. We’ve been at it since 1984, and we intend to keep doing it right.
