Frequently Asked Questions

Most standard repairs take 45 minutes to 90 minutes from the time we park the truck. A torsion spring replacement on a typical Atlanta home runs about an hour. We arrive with springs, cables, rollers, and openers on the truck so we finish in one visit. Your time matters, and we've learned since 1984 that coming back tomorrow because we didn't bring the right part is disrespectful. We'll be there when we say, and we'll be done when we say.

We inspect every moving part, tighten hardware, lubricate rollers and hinges with silicone-based lubricant suited to Atlanta's humidity, test spring balance, check safety sensors and auto-reverse, and adjust opener force settings. We also listen. A door that groans or shudders tells us something. Every door we touch gets tuned to run quiet before we leave. The 400th job gets the care of the first - that's our K.E.Y.S. code. Tune-ups run $129 to $189 and catch problems before they strand you.

Sometimes. If your door is under 10 years old and from a major manufacturer, we can often source a matching panel. For doors older than that, or from defunct brands, matching fades and embossing patterns becomes difficult. In Druid Hills and North Druid Hills, we see a lot of custom wood doors from the 1980s and 90s where panel replacement isn't practical. We'll be honest about whether repair or full replacement makes sense. We don't sell you a panel that'll look like a patch job.

For most repairs, yes - we need to test the door, review the work with you, and collect payment. If it's a routine tune-up and you've given us garage access with clear instructions, we can coordinate otherwise. But for anything involving springs, cables, or openers, we prefer you there so we can show you what we found and what we fixed. We work in your house the way we'd work in our mother's - that means explaining, not just doing.

We install and service LiftMaster, Chamberlain, and Genie openers, and we carry these on our trucks. For most Atlanta homes, we favor LiftMaster's belt-drive models with battery backup - they're quiet, handle our humidity well, and keep working when summer storms knock out power. Chamberlain offers solid value for detached garages where noise matters less. Genie screw-drive units work well for heavy doors but need more frequent adjustment in Atlanta's temperature swings. We'll recommend based on your door weight, ceiling height, and whether the garage is under a bedroom.

Yes. Raynor builds a solid steel door, and we see plenty of them in Sandy Springs and Marietta from the 2000s building boom. We stock Raynor-compatible springs, rollers, and hardware, and our journeymen are trained on their panel systems and wind-load ratings. If you have a Raynor door that's aging, we can extend its life with proper springs and hardware - or walk you through replacement options when the time comes. Either way, you'll get a square deal and a price before we start.

Belt drive is our default recommendation for attached garages - it's quiet, reliable, and handles Atlanta's humidity better than chain. Chain drive costs less and lasts forever on a detached workshop or barn-style garage in Austell or Mableton. Screw drive, like Genie's system, lifts heavy doors smoothly but needs seasonal adjustment as Atlanta's temperature swings expand and contract the rail. We ask how you use the garage, what's above it, and what you've owned before. Then we recommend, not upsell.

Yes. We're state-licensed, fully insured, and bonded for residential garage door work throughout Fulton, Cobb, and DeKalb counties. That includes every city we serve: Atlanta, Vinings, Smyrna, Fair Oaks, Mableton, Brookhaven, Sandy Springs, North Atlanta, Marietta, Druid Hills, North Druid Hills, and Austell. Our journeymen carry worker's comp and general liability coverage. We've been in business since 1984, and no reputable company lasts that long without proper protection for our customers and our crew. Ask to see our certificates - we'll show you gladly.

Standard spring, cable, roller, and opener repairs do not require a permit in Atlanta or surrounding municipalities. Full door replacement sometimes does, depending on your HOA or if you're changing the opening size. In Brookhaven and Sandy Springs, we've seen HOAs require style approval for carriage-house doors. We know the local requirements and will tell you if your job needs paperwork. If it does, we handle the permit application as part of our service. No shortcuts, no surprises.

Most days, yes. We keep a dedicated emergency route for springs that snap, cables that fray through, and doors that won't close before a storm. For standard calls in Atlanta, Vinings, Smyrna, and Marietta, we usually schedule within 24 to 48 hours. Same-day service is available for doors stuck open, cars trapped inside, or security concerns - call (855) 389-2471 and we'll tell you honestly what we can do today. We've had customers in North Druid Hills call at 7 AM and have their door working by lunch.

Do not use the door. A broken torsion spring holds hundreds of pounds of tension, and the remaining spring or the door itself can shift unpredictably. The cables may be frayed or off-track, and the opener will strain and potentially fail. In Atlanta's older neighborhoods like Druid Hills and Fair Oaks, we see original springs from the 1980s and 90s finally giving out. This is genuinely dangerous work - leave it to a trained professional with the right winding bars and knowledge. Call (855) 389-2471 and we'll prioritize your call.

Check whether the safety sensors at the bottom of the tracks are aligned and clean - Atlanta's pollen season and summer storms knock them out of alignment constantly. If both sensor lights are solid and the door still won't close, pull the red emergency release cord to disconnect the opener, then lower the door manually if it's safe. If the door is heavy, crooked, or the spring is broken, stop. A door that crashes down can injure you or damage your vehicle. Call us - we'll walk you through what's safe and get there fast.

We apply The Keystone Standard to every repair: 90 days, in writing, no arguing. If a spring we installed fails within 90 days, we replace it free. If a cable slips, a roller breaks, or anything we touched isn't right, we come back. No paperwork, no arguing. This guarantee has been our trademark since we adopted it, and we stamp it on every invoice. Standing behind our work is part of our K.E.Y.S. code. We've been in Atlanta since 1984 - we plan to be here in thirty more years, and we act like it.

Yes. The steel doors we install carry a limited lifetime warranty on the panel structure from the manufacturer, plus 10 years on the finish for most colors. Hardware - springs, rollers, hinges - carries its own warranty, typically 3 to 7 years depending on the grade you choose. Our installation labor is covered by The Keystone Standard: 90 days, in writing, no arguing. We register your warranty with the manufacturer and give you the paperwork. In 40 years of business, we've handled every warranty claim honestly and promptly.

Call us. We'll come back and make it right. The Keystone Standard means 90 days, in writing, no arguing - but our reputation means more than that. We've had customers in Mableton and Austell call a year later with a concern, and we've taken care of them because that's how you stay in business since 1984. Your home first, standing behind it always. If it's not right, we come back. That's not a slogan - it's how we operate.

We're named for the spring that powers a mechanical watch - the coiled, precisely wound component that keeps everything running. That same principle applies to the torsion or extension springs that carry your garage door's entire weight, hundreds of times a year. When the mainspring fails, nothing works. When it's krafted right and maintained with care, you never think about it. That's the standard we bring to every home in Atlanta.
