Custom Oversized
Garage Door Spring Cost
Wide three-car doors, tall RV bays and heavy custom carriage doors. Whether their springs cost the same as any pair or a good deal more comes down to one thing: whether ready-listed springs can lift the door.
Headline number: $145 to $965 on our estimate, in two cases: $145 to $520 for a pair if ready-listed residential springs can lift the door, and $490 to $965 if it needs commercial-grade springs. Parts and labor included. The door's weight decides which, so this is a door that needs a written quote.

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, first read 13 October 2026 and re-read 14 October 2026: DDM Garage Doors, DIY Garage Door Parts, Yelp cost guide and HomeAdvisor.

Show the arithmetic
- 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.
- Pair of commercial torsion springs (pair; estimate from stated inputs; includes parts, labor): $490 to $965. parts 2 x $172.49 to 2 x $332.35 (the three commercial torsion springs DDM lists), plus HomeAdvisor's commercial spring labor of $150 to $300: $494.98 to $964.70, rounded out to the nearest $5.
- Commercial torsion spring, part only (per spring; quoted; includes parts): $172.49 to $332.35. DDM Garage Doors lists three commercial torsion spring sizes at $172.49 to $332.35.
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)

What "oversized" means in spring terms
Size alone does not change the spring; weight does. Every ready-listed 7 ft torsion spring at DDM Garage Doors states what it lifts, and the heaviest lifts 165.5 lb. The heaviest at DIY Garage Door Parts lifts 158.3 lb. On two springs, that covers a door of about 330 lb. Some listings also state the lift on an 8 ft tall door, so a taller door that is not too heavy can still take ready-listed springs. Such a door is an ordinary pair job, priced like any double-spring system.
A door heavier than that needs springs made to order, or commercial-grade springs. HomeAdvisor: "If your garage door is extra-large, it might require commercial-grade springs." DDM lists three commercial torsion springs, with 3 3/4 in and 5 1/4 in inside diameters and 0.289 in to 0.3437 in wire, at $172.49 to $332.35 each, against $35.38 to $87.91 for its residential 7 ft springs.
Why we cannot price your door from its size
We found no manufacturer weight for an 18 ft, 8 ft tall, RV or custom carriage door that we could verify, so we do not give one. Door weight varies with material, insulation, glazing and hardware, and DDM Garage Doors warns that even published weights "are only approximations" and "not reliable for ordering garage door springs". The technician should weigh the door.
Cost breakdown for the commercial case
Parts: $344.98 to $664.70 for two of DDM's commercial springs. Labor: $150 to $300; HomeAdvisor: "Labor for commercial-grade spring replacement runs between $150 and $300." Total $490 to $965. Cables, drums, bearings and any opener work are separate lines. If the old cables or drums were sized for lighter springs, ask whether they need replacing too: see spring and cable replacement cost and, if more of the system is worn, full system rebuild cost.
Lead time
Stock springs can move quickly: DIY Garage Door Parts says that in most cases its orders "go out either the SAME DAY or if placed in the evening then they go out NEXT DAY." We found no published lead time for springs made to order that we could verify. Ask at quote time whether the springs are in stock or must be ordered, and when the door will be back in service. If a vehicle is trapped behind the door meanwhile, see car trapped emergency spring cost. Do not try to force a heavy door with a broken spring: HomeAdvisor says "it is unsafe to manually open your garage door when a spring is broken."
High-cycle springs on a big door
Springs wear by cycles, so a big door that is opened often uses them up like any other. DDM Garage Doors says longer life usually comes from "a larger wire size together with an appropriate increase in spring length". The only high-cycle prices we could verify are for a pair on a light 16x7 door, so ask for the upgrade on your door as a separate line; the sums are on the high-cycle spring replacement cost page.
What to ask before the quote on a custom-spec job
- What does the door weigh, and how did you find out?
- Will ready-listed residential springs lift it, or does it need springs made to order or commercial-grade springs?
- What wire size, inside diameter and length are you fitting?
- Are the springs in stock, and if not, when will the door be back in service?
- Are the cables and drums right for the new springs, or do they need replacing too? Price them as separate lines.
- What is the warranty on the springs and on the labor, in writing?
And as with any door: DASMA says "spring systems are dangerous and should be repaired only by trained professionals."

Frequently Asked
How much does it cost to replace the springs on an oversized garage door?
$145 to $965 on our estimate, in two cases. If ready-listed residential springs can lift the door, it is an ordinary pair job: $145 to $520, parts, labor and service call included. If it needs commercial-grade springs, $490 to $965: two of DDM Garage Doors' commercial springs plus HomeAdvisor's commercial labor. Neither is a quote; the door's weight decides which applies.
What counts as oversized in spring terms?
A door too heavy for the ready-listed springs. Every ready-listed 7 ft spring at DDM Garage Doors states what it lifts, and the heaviest lifts 165.5 lb; the heaviest at DIY Garage Door Parts lifts 158.3 lb. On two springs that covers a door of about 330 lb. A wider or taller door that weighs less than that can still use them; some listings also state the lift on an 8 ft door.
Does an extra-large door need commercial springs?
It might. HomeAdvisor: "If your garage door is extra-large, it might require commercial-grade springs." Commercial torsion springs have a larger inside diameter and heavier wire; DDM lists three sizes, with 3 3/4 in and 5 1/4 in inside diameters. The technician decides from the door's weight and hardware.
How long does it take to get custom springs?
We found no published lead time for springs made to order that we could verify, so ask the contractor before booking: whether the springs are in stock, and when the door will be back in service. For stock springs, DIY Garage Door Parts says that in most cases its orders "go out either the SAME DAY or if placed in the evening then they go out NEXT DAY."
What does an RV garage door spring replacement cost?
We found no published weight for an RV door that we could verify, so we cannot say which case applies. If ready-listed springs can lift it, $145 to $520; if it needs commercial-grade springs, $490 to $965 on our estimate. Ask the technician to weigh the door and to price the springs, labor and any cables as separate lines.
