Our Guarantee & Warranty - Mainspring Garage Door Co.

The Mainspring Garage Door Co. Guarantee

We stand behind every garage door repair, installation, and opener service we complete in Allen. Our 90-Day Done Right Promise means exactly what it says: if the work isn’t right, we make it right. No paperwork to file, no argument, no charge for the callback. That commitment is written on every job ticket before we leave your driveway. We’ve been serving Allen and the surrounding communities since 1984, and we didn’t stay in business this long by walking away from problems we created. When we say a square deal, we mean the price we quote is the price on the bill, and the work we do stays done.

What’s Covered

• Workmanship on every repair and installation. If a spring we installed settles wrong, if a cable we routed starts wearing unevenly, or if an opener we mounted drifts out of alignment within 90 days, we come back and fix it at no cost. That includes the labor and any replacement parts needed to correct our work.
• Parts we supply and install. We carry springs, cables, rollers, hinges, and openers from LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor on every truck. If a part we installed fails due to defect or our handling within the promise period, we replace it and handle the labor ourselves.
• Cleanup and property respect. We haul away old doors, springs, and packaging. We don’t leave oil spots on your driveway or drywall dust in your garage. If we damage something, we fix it. That’s part of the job, not an extra conversation.
• On-time arrival. We give you a real appointment window and call when we’re on the way. If we’re running late, you’ll know before you have to ask. We will be there when we say, or we’ll tell you otherwise with enough notice to respect your schedule.
• Honest, upfront pricing. The flat price is stated before any work begins. No surprises on the bill, no add-ons after the fact, no “while we’re here” upsells. If we find something unexpected, we stop and talk it through before proceeding.

Our Satisfaction Promise

If you’re not satisfied with our work, you don’t need a claim number or a manager’s approval. Call us. A live person answers our phones 24 hours a day, including nights, weekends, and holidays. Tell us what happened. We’ll schedule a return visit at the first available slot that works for you, and we’ll make it right at no charge. The 90-Day Done Right Promise is printed on your invoice so there’s nothing to negotiate. We’ve honored this hundreds of times over 42 years, usually for small adjustments: a door that settled a quarter-inch after a week of use, an opener light timer that needed reprogramming, a remote that wasn’t syncing the way the homeowner expected. We don’t treat callbacks as failures. We treat them as part of standing behind the work. Carl Dutton started this company in 1984, and he’s still the one who reviews any pattern of repeat visits to figure out what we could have done better the first time. That’s how a company stays in business for four decades in the same towns.

Licensed & Insured Backing

The 90-Day Done Right Promise is only as solid as the company behind it. We’re licensed and insured, which means there’s real financial backing if something goes seriously wrong, and there’s a regulatory body that holds us accountable for how we operate. That matters in Allen, where garage doors on newer homes in Watters Creek and Twin Creeks can weigh 300 pounds or more, and a failed installation isn’t just an inconvenience. Our technicians are background-checked, uniformed, and trained as journeymen under our K.E.Y.S. values code: Krafted right, Every time, Your home first, Standing behind it. Insurance and licensing are the floor, not the ceiling. The ceiling is that we don’t want to be the company you warn your neighbors about.

Standing Offers That Don’t Expire

These aren’t flash sales. They’re the terms we’ve set because they make sense for the work we do.

• $50 off any repair over $250. Applies to labor and parts combined. No code needed, no expiration date.
• Free second opinion on any written estimate. Bring us a competitor’s written quote. We’ll inspect the door ourselves and tell you if the scope and pricing hold up. No obligation.
• $89 seasonal tune-up. Lubrication, balance check, safety sensor test, hardware inspection. Recommended once a year, especially before summer heat sets in around Allen.
• Permanent 5% discount for seniors and veterans. Applied to every qualifying job, every time. No ID re-verification after the first visit.

What “No Surprises” Actually Means

We’ve heard the stories. A technician quotes $200 over the phone, then hands a $600 invoice because “the spring was heavier than expected” or “we had to replace the cables too.” That doesn’t happen here. We inspect before we quote. If we’re doing a repair, we test the door’s balance, check the cables and rollers, and look at the opener’s force settings. Then we give you a flat price. If you approve it, we do the work. If you don’t, you pay nothing for the diagnosis. That’s a square deal. It’s also why most of our jobs are completed in a single visit: our trucks carry the inventory to handle standard residential doors without a parts run.
