DIY vs Professional
Spring Replacement

Professional labor and the service call for a spring pair run about $75 to $200. The door industry's position is that neither torsion nor extension springs are a DIY job. Here is why, and what a professional costs.

CRITICAL SAFETY WARNING

DASMA, the Door and Access Systems Manufacturers Association, says “spring systems are dangerous and should be repaired only by trained professionals.” That applies to torsion and extension springs alike. Always hire a trained garage door technician for spring work. (DASMA safety tips, read 13 October 2026.)

What a Professional Replacement Costs

Service	Parts	Labor	Total
Extension spring pair, professional	$59.84 to $145.80	$75 to $200	$130 to $350
Torsion spring pair, professional	$70.76 to $315.88	$75 to $200	$145 to $520

How we price this: Our ranges are estimates built from published inputs, not quotes: retail spring prices, the service-call and hourly rates in Yelp's cost guide, and job times from HomeAdvisor and Yelp. Low ends are rounded down and high ends up to the nearest $5. Sources, read 13 October 2026: DIY Garage Door Parts, extension springs, Yelp cost guide, HomeAdvisor, DDM Garage Doors and DIY Garage Door Parts. HomeAdvisor and Angi are both owned by Angi Inc., which pays this site a commission for quote requests. (Angi Inc. 2025 Form 10-K)

Show the arithmetic

Pair of extension springs replaced (pair; estimate from stated inputs; includes parts, labor, service call): $130 to $350. parts 2 x $29.92 to 2 x $72.90, plus labor $75 to $200 (a $75 to $100 service call covering the first hour, plus up to one more hour at $100): $134.84 to $345.80, rounded out to the nearest $5.
Pair of torsion springs replaced (pair; estimate from stated inputs; includes parts, labor, service call): $145 to $520. parts 2 x $35.38 to 2 x $157.94, plus labor $75 to $200 (a $75 to $100 service call covering the first hour, plus up to one more hour at $100): $145.76 to $515.88, rounded out to the nearest $5.

Parts are priced at what the two suppliers charge the public. Installers buy for less and many mark parts up, and neither figure is published, so a quote's parts line can be higher than ours.

Wage check: The BLS puts the median mechanical door repairer (the occupation that includes garage door mechanics) at $26.79 an hour (May 2025). Wages are 70.0% of private-industry employer costs (June 2026), so that technician costs an employer about $38.27 an hour before the van, insurance, overhead and profit. Yelp's $40 to $100 hourly rate sits at or above that cost, which is what a billed rate should do. (BLS OEWS, 49-9011 Mechanical Door Repairers; BLS Employer Costs for Employee Compensation)

We do not price a DIY row. Spring parts alone cost less than a professional visit, but DASMA's guidance covers both spring types, so DIY is not an option this site recommends at any saving.

Extension Springs Are Not a DIY Job Either

Extension springs look simpler than torsion springs, but DASMA's safety tips make the same call for both. What DASMA says about extension springs:

When your garage door is down, extension springs are under high tension.
If an extension spring breaks, it may cause injury. A safety cable that runs through the spring and secures to the wall or ceiling at each end keeps a broken spring contained.
If you have extension springs but no safety cable, call a local door dealer for a safety inspection.
Spring systems should be repaired only by trained professionals.

Why You Should Never DIY Torsion Springs

Torsion springs store enough energy to kill, they can deliver 30,000+ inch-pounds of torque

Improper winding can launch the spring bar at high velocity

Incorrect spring size leads to premature failure or door imbalance

No warranty on DIY work, if something breaks, you pay twice

A falling garage door (250-450 lbs) can cause serious injury

Most homeowner insurance does not cover DIY garage door injuries

What a Professional Brings

Correct spring sizing, measured by wire gauge, length, and inside diameter
Proper winding bars sized to the winding cone, and the training to use them (never a screwdriver)
Liability insurance, if something goes wrong, their insurance covers it
Warranty: Yelp says common springs typically carry 1 to 5 years and some heavy-duty springs a lifetime warranty; get the labor warranty in writing too
Full system inspection, they will check cables, drums, rollers, and brackets
Speed: HomeAdvisor says a skilled technician replaces two springs on a standard door in 30 minutes to one hour

Bottom line: Torsion or extension, hire a trained garage door technician. The $75 to $200 in labor buys you correct sizing, a warranty and the training DASMA says spring work needs.

Common Questions

Can I replace garage door springs myself?

No, for either type. DASMA (the Door and Access Systems Manufacturers Association) says on its garage door safety tips page (read 13 October 2026) that "spring systems are dangerous and should be repaired only by trained professionals." That includes extension springs: DASMA notes they are under high tension when the door is down and a broken one may cause injury, which is why each needs a safety cable running through it. Hire a trained garage door technician.

Is the labor saving worth doing spring replacement yourself?

No. Professional labor and the service call run about $75 to $200 for one visit on the cost table on this page, but DASMA says spring systems should be repaired only by trained professionals, whichever type your door has. We do not present DIY replacement as an option at any saving.
