Garage door springs are the single most expensive thing to get wrong on this repair. Price a spring job right and you'll pay a fair rate for a repair that lasts 10+ years; price it wrong and you'll either overpay by hundreds or hire someone who cuts corners on a component that can seriously hurt you. This 2026 guide breaks down real US pricing, why torsion and extension springs cost different amounts, what a fair quote looks like, and how to spot an inflated one before you sign.
For a standard single-car residential door, expect to pay $180 to $350 to replace one torsion spring, parts and labor included. Replacing both springs at the same time (which is what any honest tech will recommend) usually runs $280 to $500. Two-car doors with heavier springs typically land between $350 and $650 for the pair.
Extension springs — the older side-mounted kind — are cheaper. A single extension spring is $50 to $120 in parts, and most shops charge $150 to $250 to swap the pair. If your door still uses extension springs and has never had safety cables installed, budget another $30 to $60 to add them; it is not optional and any pro who skips them is cutting a corner that can maim someone.
The spring itself is $40 to $120 in parts for a standard residential wire size. The rest of the ticket is labor, truck roll, and warranty. A licensed tech carries multiple wire sizes and lengths, uses a proper torsion bar rather than a screwdriver, and balances the door afterward — that's what you're paying for, and it's why the fair market rate has held roughly steady while everything else has crept up.
Door weight is the biggest cost variable. A steel double-car door with a wood overlay can weigh 350 to 450 pounds and needs a much beefier spring than a single-car aluminum door. Techs price by wire size (usually stamped on the cone) and door weight, not by a flat rate. Insulated doors also weigh more than single-layer steel, which is why an insulated upgrade often bumps the spring class up a tier at the next replacement.
If your door has two springs and one broke today, the other one is already 90% through its rated life. Replacing just the broken one saves you maybe $80 now and almost guarantees a second service call within 6 to 18 months — meaning another trip charge, another day off work, and often another emergency-hours surcharge. Every reputable garage door company recommends replacing the pair, and it's not upselling; it's basic math on cycle life.
The only time replacing just one makes sense is when the other spring is genuinely new (less than a year old) and you have the receipt to prove wire size and cycle rating. Even then, most techs will still recommend matching the pair so the door balances correctly.
Do not operate a door with a broken spring. The opener is not rated to lift the full weight of the door and will burn out its gears — turning a $300 spring job into a $700 spring + opener repair. If you're not sure whether a spring is broken, look above the door: a healthy torsion spring is a tight uninterrupted coil, and a broken one has a visible 1 to 2 inch gap in the middle.
The most common scam in this trade is the $19 service call that turns into a $1,500 invoice for a spring, cables, rollers, bearings, and a mysterious 'safety inspection.' Get quotes from at least two pros, ask for the wire size and length before they arrive, and confirm the price is all-in with tax and disposal. Anything above $600 for a standard residential pair deserves a second opinion, and any tech who refuses to itemize the invoice is telling you something about how they do business.
Standard torsion springs are rated for 10,000 cycles — roughly 7 to 10 years for a family that opens the door four times a day. Extended-life springs rated for 20,000 or 30,000 cycles cost 40% to 80% more up front but often outlast two standard sets, so they're a smart upgrade if you plan to stay in the home. Ask for high-cycle springs by name at your next replacement.
Technically yes, realistically no. Torsion springs store 200+ pounds of force under tension and have sent countless DIYers to the ER. If you don't own a proper set of hardened winding bars, a locked ladder, and a torsion cone chart, the $250 you'd save is not worth a broken hand or worse. Hire a licensed tech and keep your fingers.
Steel gets more brittle as temperatures drop, so springs at the end of their cycle life almost always fail on the first cold morning of the season. It's not that the cold caused it — the spring was going to break anyway; the cold just tipped it over the edge. This is why so many pros are booked solid in November and December, and why booking a preventive replacement in the summer is often a smart move.
Almost never. Springs are considered normal wear-and-tear parts, the same as brake pads on a car. Insurance may cover spring damage if it was caused by a covered event — a tree falling on the door, for example — but a routine break at end of life is on you. It's not worth filing a claim over a $300 repair even if it were covered.
Sometimes. A true lifetime warranty that covers parts and labor on a high-cycle spring is genuinely valuable if the company has been in business more than 5 years and services your area. A 'lifetime parts only' warranty is worth much less — the labor bill is usually 60% of the invoice, so you'll still pay $150+ on a warranty call. Read the fine print before assuming lifetime means free.
