The Mainspring Garage Door Co. Guarantee
We stand behind every garage door repair, installation, and opener service we complete in New Braunfels because our name is tied to the work. Carl Dutton started this company in 1984, and in 42 years we’ve learned that a guarantee only matters if you honor it without making the customer fight for it. Our 90-Day Done Right Promise means exactly what it says: if something we installed or repaired isn’t right, we come back and make it right. No paperwork to dig up, no dispute process, no arguing about whether the problem counts. It’s written on every job sheet, and we mean it.
We’ve fixed springs in Gruene that failed early because the previous installer used the wrong wire size. We’ve replaced openers in River Chase where the original company vanished when the motor burned up six weeks later. That’s why we don’t promise “satisfaction” in the abstract. We promise to return, at no charge, and fix what we did wrong or what failed because of our work. In New Braunfels, where summer heat hits 105 degrees and humidity swells wooden doors every spring, that kind of backing matters. A garage door isn’t just an entry point. It’s security for your family, protection for your vehicles, and often the largest moving component in your home. We treat it that way.
What’s Covered
- Workmanship on every repair and installation. Our technicians are trained journeymen who work under the K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it. If a spring we install makes noise after two weeks, or a door we balanced starts drifting closed, that’s on us to correct.
- Parts integrity and proper specification. We carry springs, cables, rollers, hinges, and openers from LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor on every truck. If we use a part that fails prematurely due to defect or incorrect sizing, we replace it and cover the labor.
- Job site cleanup and respect for your property. Our technicians arrive in uniform, background-checked, and prepared to leave your garage as clean as they found it. Old springs, worn cables, and packaging debris leave with us, not in your trash can.
- On-time arrival and communication. We will be there when we say. If traffic on I-35 or a job in Vintage Oaks runs long, you’ll get a call with a real ETA, not a four-hour window that stretches into darkness.
- Honest, upfront pricing with no surprises on the bill. The flat price is stated before any work begins. We don’t start disassembling your door and then discover “additional problems” that balloon the cost. What we quote is what you pay.
Our Satisfaction Promise
If you’re not satisfied with our work, you call (830) 689-6216 and a live person answers. Not a phone tree, not voicemail, not an after-hours answering service that takes a message and promises a callback. Day or night, weekend or holiday, you’ll speak to someone who can dispatch a technician under the 90-Day Done Right Promise.
Here’s how it actually works. We return to your home in New Braunfels, assess what isn’t right, and fix it. No “let us check with the office.” No “that part isn’t covered because…” The promise is written on your original invoice, and we don’t make you produce it from a filing cabinet. We keep records. We know what we did, when we did it, and who did the work. If we made a mistake, we own it. If a part failed, we handle the replacement. If the door isn’t running quiet and smooth the way we promised, we adjust until it is.
Carl Dutton put this in writing because he’s seen too many homeowners in Comal County get the runaround from contractors who treat a warranty like a negotiation. That’s not a square deal. Our promise is simple: if it’s not done right, we make it right. Period. No expiration anxiety at day 89, no wondering if your “lifetime warranty” excludes labor or shipping or “acts of God.” Ninety days of clear coverage, and if you’re a repeat customer or we’ve done extensive work, we often extend that protection informally because we know your door and we stand behind our reputation in this community.
Licensed & Insured Backing
A guarantee on paper is only as good as the company that can back it up. Mainspring Garage Door Co. is licensed and insured, which means if something goes seriously wrong, you’re not chasing a ghost or paying out of pocket. We’ve been in New Braunfels since 1984. We’ve served 13 local communities. We’re not a truck-and-a-cellphone operation that reincorporates under a new name when the reviews turn sour.
Insurance matters on garage door work because these doors are heavy, springs are under extreme tension, and accidents can damage property or cause injury. Our coverage protects your home, your vehicles, and our technicians while they’re on your property. Licensing means we’ve met state requirements, passed background checks, and operate as a legitimate business with a physical presence you can find. When Carl Dutton sends a technician to your home in New Braunfels, that person is employed by us, trained by us, and accountable to us. Not a subcontractor we found that morning.
The 90-Day Done Right Promise, the K.E.Y.S. training code, the stocked trucks, the live phone answering, the background checks and uniforms, all of it sits on this foundation: we’re a real company with real credentials, and we’ve been here long enough to know that cutting corners on insurance or licensing is how you disappear. We’re not going anywhere. When we say we stand behind our work, we have the structure to actually do it.
Standing Offers That Don’t Expire
Our guarantee isn’t the only promise we keep permanently. These offers have no end date because we believe in consistent, fair pricing for New Braunfels homeowners:
- $50 off any repair over $250 - applied at checkout, no coupon code to hunt down
- Free second opinion on any written estimate - bring us a competitor’s quote and we’ll review it honestly
- $89 seasonal tune-up - inspection, lubrication, balance check, and safety test
- Permanent 5% discount for seniors and veterans - no ID verification song and dance, just mention it when you call
Common Questions About Our Guarantee
What if my garage door problem happens after the 90 days?
Call us anyway. The 90-Day Done Right Promise covers our workmanship and parts specifically, but we’ve been known to extend goodwill to longtime customers in New Braunfels. If we installed your door or opener, we know its history and we’ll tell you honestly whether the issue is related to our work or normal wear. Estimates are always free, so you have nothing to lose by asking.
Will the price change once you start working?
No. The flat price is stated before any work begins. If we discover something unexpected, like a rotted frame behind the track or a door that was modified by a previous owner, we’ll stop and explain the situation with a new price for your approval. We don’t proceed until you agree. No surprises on the bill, ever.
Do you carry parts on the truck, or will I wait for ordering?
Our trucks are stocked with springs, cables, rollers, hinges, and openers for all major brands. Most jobs in New Braunfels are completed in a single visit. If you have an unusual door or a specialty part, we’ll tell you upfront if we need to order, and we’ll give you a realistic timeline. Call (830) 689-6216 to check availability for your specific brand and model.
Who actually answers the phone at midnight?
A live employee of Mainspring Garage Door Co., not an answering service reading from a script. We staff our phones 24/7 including nights, weekends, and holidays. If you have an emergency in Canyon Lake at 2 a.m. or a spring that snapped on Christmas morning, you’ll speak to someone who can dispatch help, not someone who promises “we’ll have them call you in the morning.”
What brands do you guarantee work on?
We’re factory-familiar with LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor. Our 90-Day Done Right Promise applies regardless of brand, but our deep knowledge of these eight manufacturers means we diagnose faster, repair correctly the first time, and don’t guess at specifications. In New Braunfels, where many homes in developments like River Chase and Copper Ridge have builder-grade doors that need knowledgeable service, that expertise matters.
