Frequently Asked Questions

Our technician arrives during the scheduled window, inspects every moving part of your door system, and explains what they find before doing any work. They'll show you worn springs, frayed cables or bent tracks, quote the flat price, and get your approval. Most repairs are finished in one visit because our trucks carry the springs, cables and openers we need. We tune every door we touch to run quiet before we leave.

A standard residential garage door installation takes four to six hours from removal of the old door to final testing of the new one. Custom wood doors or jobs requiring structural header reinforcement, which we sometimes encounter in the older homes near Shavano Park's original ranch estates, may take a full day. We don't rush. The door needs to be plumb, balanced and safe before we consider it done.

If your door is less than fifteen years old and the damage is limited to springs, cables, rollers or one panel, repair usually makes sense. If the door has significant rust, multiple failed panels, or an outdated opener that lacks modern safety sensors, replacement is often the smarter long-term investment. In Shavano Park's sun and occasional hail, we've seen doors that look rough on the outside but have solid cores, and doors that look fine but have compromised structural integrity. We'll give you an honest assessment either way.

We recommend a professional tune-up once a year for most Shavano Park homes. The Hill Country's temperature swings from summer highs near 100 to winter freezes stress metal components, and the limestone dust that blows in from construction and ranch roads accelerates wear on rollers and hinges. An annual inspection catches fraying cables and weakening springs before they fail completely, which usually happens at the worst possible moment.

You can apply a silicone-based spray lubricant to the hinges, rollers and track every six months, which helps. Do not use WD-40, grease or oil, which attract dust and gum up the works. We do not recommend homeowners adjust spring tension, tighten cables or work on the opener's force settings. Garage door springs are under extreme tension, and a slip can cause serious injury. Leave that to a trained professional.

We primarily install Clopay steel and carriage-house doors, which hold up well to Hill Country sun and hail, and we stock a range of LiftMaster and Chamberlain openers. We've found Clopay's insulated models particularly suited to Shavano Park homes where the garage shares a wall with living space. If you have a preference for another brand, we'll work with you to source it, though our standard inventory lets us complete most jobs without delay.

Yes. Our trucks are stocked with torsion and extension springs, cables, rollers, hinges, weatherstripping, LiftMaster and Chamberlain openers, and remotes for most common models. This is how we finish most repairs in one visit. For older or specialty doors, especially some of the custom wood units we see in Hill Country Village and Olmos Park, we may need to order a part and return. If so, we'll tell you upfront and schedule the follow-up before we leave.

Sometimes. If your door is a common Clopay model from the last ten to fifteen years, we can often match the panel, color and embossing pattern. If the door is older, discontinued, or a custom color that has faded in the Texas sun, a perfect match may not be possible. In those cases, we'll explain your options, including replacing the damaged section with a close match or quoting a full door replacement. We won't pretend a mismatch looks right.

Every pro working under our name is required to hold the license and insurance Texas requires for garage door work. We carry general liability coverage and verify that each technician maintains their credentials. When you hire us, you're hiring a local branch of Mainspring Garage Door Co., an established brand with standards that apply nationwide. The local knowledge comes from our team here; the guarantee and backing come from the brand.

We're both. This is a local branch serving Shavano Park, Cross Mountain, Castle Hills, Helotes and the surrounding communities, led by Carl Dutton. Mainspring Garage Door Co. is an established brand that existed before this location opened, with branches in other markets operating under the same standards. You get the accountability of a known brand plus the care of a team that lives and works here.

Yes. Our phone is answered 24 hours a day, seven days a week, by a live coordinator who connects you with our local team. If your door is stuck open, stuck closed, or has a broken spring that's left your car trapped, we'll get someone out as soon as possible. We don't guarantee a specific arrival time, but we prioritize genuine emergencies and have completed same-day repairs everywhere from Timberwood Park to Terrell Hills.

A door that won't close and leaves your home exposed, a door that's stuck shut with vehicles inside, a snapped spring with the door hanging crooked or partially open, or any situation where the door feels unsafe to operate. If you're unsure whether it's an emergency, call us at (830) 224-4217 and we'll help you assess. If it can wait until morning without risk, we'll tell you. If it can't, we'll get you scheduled.

For most repairs, yes. Because our trucks carry springs, cables, rollers and openers, we can often complete the job on the first visit if you call early in the day. Same-day availability depends on our schedule and your location. Shavano Park and nearby Cross Mountain are within our core service radius, so we can usually reach you quickly. Installation and replacement work is measured, ordered and scheduled, not done same-day.

We apply The Keystone Standard to every repair: 90 days, in writing, no arguing. If a part we installed fails or a repair doesn't hold, we come back and make it right at no charge. This applies to labor and parts we supply. For new door and opener installations, manufacturer's warranties apply to the equipment, and we back our installation work with the same 90-day guarantee. We stand behind it because we do the work right the first time.

The Keystone Standard is our promise on every job: 90 days, in writing, no arguing. It's stamped on every page of our site and detailed in our terms. If something we did isn't right, we come back. No paperwork maze, no he-said-she-said. This is how we've operated since opening our Shavano Park branch in 2016, and it's how we plan to still be operating when your kids call us for their own homes.

Yes. Our installation labor is covered by The Keystone Standard: 90 days, in writing, no arguing. Beyond that, the doors and openers we install carry manufacturer warranties. Clopay typically offers limited lifetime warranties on certain door components, and LiftMaster and Chamberlain back their openers with multi-year motor and parts coverage. We'll explain exactly what's covered by whom before you sign anything.

Call us. The K.E.Y.S. values that guide our work include "Standing behind it" - if it's not right, we come back, no paperwork, no arguing. Carl Dutton has led this branch for ten years, and our reputation in Shavano Park, Hill Country Village and Castle Hills depends on every homeowner being treated fairly. We want you to call us again, and to tell your neighbor to call us. That only happens if you're genuinely satisfied.

Call (830) 224-4217 any time. A live coordinator will connect you with our local team, and we'll find a time that works.
