Frequently Asked Questions - Garage Door
We've been fixing, replacing, and tuning garage doors since 1984. Here are the questions we hear most from homeowners, answered straight.
Pricing & Cost FAQs
Most garage door spring repairs in Los Angeles run between $180 and $340 for a standard torsion spring replacement, including parts and labor. The price varies with spring size, door weight, and whether you have one or two springs. Heavier custom wood doors in neighborhoods like Bel Air or Hancock Park sometimes need higher-cycle springs that cost more. We quote the flat price before we start, so there's no surprises on the bill. Call (844) 755-5838 for a free written estimate.
Repair is usually cheaper for doors under 15 years old with isolated problems like a broken spring, worn rollers, or a faulty opener. Replacement makes more sense when the door is dented, rotted, or the panels are failing, since you're paying for labor twice if you repair now and replace in two years. In Los Angeles, a new single-layer steel door installed typically starts around $1,200, while repairs for common issues often stay under $500. We'll tell you honestly which path saves money long-term. Call (844) 755-5838 and we'll come look at no charge.
A new garage door opener installed in Los Angeles typically ranges from $350 for a basic chain-drive unit to $650 for a belt-drive with Wi-Fi and battery backup. The price includes removal of the old opener, mounting, safety sensor alignment, and testing. Homes in hillside areas like the Hollywood Hills or Laurel Canyon sometimes need reinforced ceiling brackets, which can add $50 to $100. We carry LiftMaster and Chamberlain models on our trucks and can usually install same day. Call (844) 755-5838 for an exact quote.
Low bids often mean aftermarket springs rated for 5,000 cycles instead of 10,000, untrained labor, or a bait-and-switch where the price climbs once they're in your driveway. We've seen it in Los Angeles for decades. Our springs are rated for the door's actual weight, our techs are trained journeymen, and the price we quote is the price you pay. A square deal costs more than a cheap fix, but it costs less than doing it twice.
Service & Process FAQs
We arrive in a marked truck with springs, cables, rollers, and openers stocked to finish in one visit. The tech inspects the door system top to bottom, identifies what's worn or broken, and quotes a flat price before touching a wrench. With your go-ahead, we do the work, then tune the door for quiet, balanced operation and test the safety reverse. Most standard repairs take 60 to 90 minutes. We'll be there when we say, and we stand behind it.
A standard single or double door replacement takes 3 to 5 hours from removal of the old door to final testing. Custom wood doors or conversions from one-piece to sectional systems in older Los Angeles homes, especially in neighborhoods like Silver Lake or Echo Park with tight garages, can run a full day. We don't rush. Every track is plumb, every spring is wound to spec, and every opener is programmed and tested before we leave.
Yes. We work with manufacturers who offer flush, raised-panel, carriage-house, and contemporary styles in steel, wood composite, and aluminum. If your home is a 1920s Spanish Revival in Los Feliz or a midcentury in the Valley, we can match the look. Bring a photo or we can visit to measure and show samples. The goal is a door that looks like it belongs, not like a patch job.
We prefer you home for the initial inspection so we can show you what's worn and agree on the scope. For straightforward spring or cable replacements where you've already approved the work, arrangements can be made. We never enter a home unaccompanied, and we lock the garage when done. Your home first - we work in your house the way we'd work in our mother's.
Brands & Parts FAQs
We install and service Raynor, LiftMaster, and Chamberlain products because they've held up across thousands of jobs since 1984. Raynor builds a solid residential door with good insulation options for Los Angeles garages that double as workshops. LiftMaster openers are reliable and parts are available when something eventually wears. We don't push the most expensive model; we match the product to your door weight, usage, and budget.
Genie makes a decent opener, especially their chain-drive and screw-drive lines, and we service them when they come our way. We don't stock Genie for new installs because we've found LiftMaster and Chamberlain have better long-term parts availability and quieter belt-drive options. If you've got a Genie that's running fine, keep it. When it fails, we'll give you an honest comparison.
Usually yes. We carry common springs, cables, rollers, and hinges for doors going back to the 1980s. Some proprietary track systems from defunct manufacturers in older Los Angeles homes can't be matched exactly, in which case we'll explain whether a component swap or full replacement makes sense. We don't sell you a new door unless you need one.
Torsion springs mount above the door on a metal shaft and twist to lift the door; they're safer, last longer, and allow smoother operation. Extension springs stretch along the horizontal tracks on each side and are more common on older or lighter doors. Most Los Angeles homes built after 1990 have torsion systems. Extension springs are under high tension and can be dangerous to handle - we recommend a trained professional for any spring work.
Licensing & Insurance FAQs
Every pro working under our name is required to hold the license and insurance their state requires. In California, that means a C-61/D-28 license for garage door and gate work, plus general liability coverage. We verify these credentials for every location in our network, including our Los Angeles team. You can ask to see the paperwork; no one here minds.
Permit requirements vary by city. Los Angeles typically requires a permit for new door installations but not for like-for-like replacements or repairs. Our local team knows the permitting rules for Los Angeles, Long Beach, Santa Clarita, and the other markets we serve. If a permit's needed, we handle the paperwork and include it in the quote. No surprises on the bill.
Ask for proof of state licensing, general liability insurance, and whether the quote is flat or time-and-materials. Check how long they've been in business under the same name - fly-by-night operators rebrand every few years. We've been Mainspring Garage Door Co. since 1984, and our name is stamped on every job. Ask about warranty terms in writing, not just verbally. A company that plans to be around honors its promises.
Emergency & Response FAQs
We schedule same-day appointments when our calendar allows, which is most weekdays in the Los Angeles area. Our hours are Monday through Friday 7:00 AM to 8:00 PM, Saturday 7:30 AM to 8:00 PM, and Sunday 7:30 AM to 8:00 PM. Spring failures and doors off-track get priority because they're security and safety issues. Call (844) 755-5838 and our live coordinator will connect you with the local team nearest you.
Disconnect the opener by pulling the red emergency release cord, then try to lower the door manually. If it won't move or hangs crooked, a spring or cable is likely broken, and the door is under unbalanced weight. Don't force it. A garage door can weigh 150 to 400 pounds, and a falling door causes serious injury. Call us at (844) 755-5838. We'll get a tech out during our operating hours and secure the door if needed.
Yes, we're open Saturday and Sunday 7:30 AM to 8:00 PM. Weekend appointments fill faster, especially in spring when temperature swings stress door components across Los Angeles. If your door fails Saturday morning, call early. We'll be there when we say, or we'll tell you honestly if the next available slot is Monday.
Warranty & Guarantees FAQs
Every repair is covered by our Keystone Standard: 90 days, in writing, no arguing. If a spring we installed fails or a cable slips inside 90 days, we come back and fix it at no charge. No paperwork battle, no "prove you didn't hit it." We also honor manufacturer warranties on doors and openers, which typically run 1 to 10 years depending on the product. Standing behind it is one of our K.E.Y.S. values.
Labor and parts we supply are covered for 90 days against defects in workmanship or materials. It doesn't cover damage from accidents, weather events, or normal wear beyond the warranty term. If you're unsure whether your issue qualifies, call (844) 755-5838 and we'll tell you straight. We've been honoring this guarantee since 1984, and we intend to keep doing it for decades more.
Yes. Raynor doors typically carry a limited lifetime warranty on the door sections and hardware, with 1 to 3 years on the finish depending on the model. LiftMaster and Chamberlain openers come with motor warranties ranging from 4 years to lifetime on premium models. We register your warranty with the manufacturer and give you the paperwork. If something fails during the coverage period, we handle the claim and the repair.
Call us. If the door isn't running quiet and smooth, or if something doesn't feel right, we come back and make it right. No arguing, no restocking fees, no "that's just how these work." Our K.E.Y.S. code says "Your home first" and "Standing behind it" for a reason. We've built this company since 1984 on homeowners who trust us enough to recommend us to their neighbors. One bad job undoes ten good ones, so we don't let bad jobs stand.
