Frequently Asked Questions

Most repairs - spring replacement, cable swap, roller upgrade, opener adjustment - take 60 to 90 minutes. We carry the common spring sizes, cables, and hardware for standard doors on every truck, so we're not running to a supplier while your car is trapped inside. A full door replacement is scheduled as a half-day job once the door arrives.

We inspect every moving part: springs, cables, rollers, hinges, tracks, and the opener's force settings. We tighten hardware, lubricate with proper garage-door grease (not WD-40, which attracts dust), test the auto-reverse, and check door balance. In Bulverde's hard water country, we also look for corrosion on bottom brackets and cable drums. The whole visit takes about 45 minutes.

We schedule repairs Monday through Saturday, 7:00 AM to 8:00 PM, and Sunday 7:30 AM to 8:00 PM. Same-day availability depends on when you call and where you are - we're faster to Bulverde and Timberwood Park than to outlying areas. Emergency calls during open hours get priority. Call (726) 256-8286 and our live coordinator will find the next open slot.

For most repairs, yes - we need to test the door with you, show you what was done, and collect payment. For scheduled maintenance or if you've pre-approved work, we can arrange access with a trusted neighbor or property manager. We've done this for snowbirds in Universal City and Castle Hills who head north for the summer.

First, make sure the opener is plugged in and the breaker hasn't tripped - sounds obvious, but it happens. Check if the door is locked manually; many Bulverde homeowners forget the slide lock. Look for an obstruction in the track or a broken spring above the door (you'll see a gap in the coil). Don't try to force the door or release the opener if a spring is broken. The door is heavy, and the wrong move can damage the opener or hurt you.

We carry Clopay and Amarr as our primary lines - both manufacture well in Texas heat and hold up to Hill Country temperature swings. Wayne Dalton and Craftsman openers are also available by request. We don't push every brand; we match the door to your budget, your home's style, and how long you plan to stay.

Yes. Our trucks stock torsion springs in the common wire sizes for doors up to 18 feet wide, extension springs, cables, rollers, hinges, weatherstrip, and circuit boards for major opener brands. The oddball part - say, a custom track bracket for a 1970s door in Olmos Park - we order and return to install, but that's rare.

We work on Craftsman, Chamberlain, LiftMaster, Genie, and most major brands. If your opener is more than 15 years old and the motor or logic board has failed, we may recommend replacement - parts get scarce, and a new opener with modern safety features is often the better value. We'll tell you straight either way.

Big-box springs are often rated for 10,000 cycles - about 3-5 years of normal use. The springs we install are rated for 25,000 to 30,000 cycles, properly sized to your door's weight, and wound with the right tension. A spring that's too strong wears out your opener; too weak, and it fails early. We measure, we calculate, we install. That's the Krafted right piece of our K.E.Y.S. code.

Every pro working under our name is required to hold the license and insurance the state of Texas requires for garage door work. We're also insured for general liability and workers' compensation. If you want proof, we'll email certificates before we schedule. No paperwork, no arguing.

We require every technician to pass the screening our brand standards demand. That includes driving record checks and the background review our insurance carrier requires. The person who arrives at your door in Terrell Hills or Helotes is a trained journeyman or apprentice working toward it, not a day laborer.

Ask for proof of insurance, ask how they price (flat rate or hourly), and ask what happens if something goes wrong. A company that won't put a warranty in writing is telling you something. We put ours in writing: The Keystone Standard, 90 days, no arguing. We've been in Bulverde since 2016, and we plan to be here when you need us again.

A door stuck open with storms coming, a car trapped inside on a workday, a broken spring with the door hanging crooked and about to fall - those are emergencies. A noisy roller or a remote that works half the time can wait for a scheduled visit. If you're unsure, call (726) 256-8286 and our coordinator will help you sort it out.

We're based in Bulverde, so Timberwood Park and Garden Ridge are typically our fastest response areas. Hill Country Village, Cross Mountain, and Live Oak are also well inside our regular service radius. We don't promise arrival windows we can't keep, but we'll be there when we say. Our hours are Monday through Saturday 7:00 AM to 8:00 PM, Sunday 7:30 AM to 8:00 PM.

Don't try to close it manually if a spring is broken - the door can slam shut and hurt someone or damage the opener. If the opener is running but the door isn't moving, pull the red emergency release cord only if the door is fully closed; otherwise, leave it. Clear the area, secure what you can, and call us during our open hours. If weather is a threat, a tarp over the opening beats a risky DIY fix.

The door itself carries the manufacturer's warranty - typically 10 years on sections for Clopay and Amarr steel doors, with hardware warranties varying by component. Our labor is covered by The Keystone Standard: 90 days, in writing, no arguing. If a track bolt loosens or a spring makes noise inside that window, we come back and make it right.

Yes. Every repair we make in Bulverde, Cibolo, or anywhere in our service area carries the same 90-day Keystone Standard. Springs, cables, rollers, openers - if our part or our work fails, we replace it. We don't make you dig up paperwork or argue with a dispatcher. We stand behind it.

It means if something we did isn't right, we don't debate whether it's "normal wear" or blame the weather. We come back and fix it. Carl Dutton set that standard when we opened this branch, and it's how we've operated ever since. Every time - the 400th job gets the care of the first.

Of course. We're not a pop-up operation that disappears after the sale. We've been in Bulverde since 2016, and we service doors we installed ten years ago with the same attention we give new ones. Your home first - we work in your house the way we'd work in our mother's. That's not a slogan; it's how we stay in business.

The manufacturer's door warranty typically transfers to a new owner with proper documentation. Our 90-day labor warranty applies to the original customer and job. If you're selling and want the door serviced before listing, call us - a smooth, quiet door is a small detail that makes a strong impression on buyers in Castle Hills or Olmos Park.
