9x7 Garage Door
Spring Cost
The North American suburban single-car default. If your home was built between 1975 and today and has one single garage door, it is very likely this size. Here is the pricing baseline and the most common upsells.
Headline number: $175 to $325 installed for a 9x7 single-car door spring replacement. Mid-point around $235.

Why 9x7 is the de facto residential standard
A 9 foot wide opening clears a full-size pickup truck with the mirrors extended, including the late-model F-150, Silverado, and Ram trucks that dominate North American driveways. A 7 foot tall opening clears those same trucks with a standard roof rack but stops just short of allowing a roof tent or full cargo carrier. The size is therefore the smallest standard that handles modern truck width without requiring driver care on entry.
Builders settled on 9x7 as the single-car default in the 1970s, when full-size vehicles were beginning to stabilise at the current width. Every major North American manufacturer (Clopay, Amarr, Wayne Dalton, Garaga, Haas) stocks 9x7 as a standard SKU in every insulation tier from uninsulated to fully insulated steel. The spring hardware is correspondingly standardised, which is why this is the easiest size for any installer to quote and the most predictable to repair.
What a 9x7 door weighs
Uninsulated single-skin steel: 130 to 160 pounds. Polystyrene-insulated steel: 160 to 190 pounds. Polyurethane-insulated steel: 190 to 220 pounds. Solid wood carriage style: 250 to 350 pounds (rare in this size but possible). The vast majority of 9x7 installs land in the 140 to 180 pound range, which is squarely in single-spring territory with a 0.243 inch wire torsion spring at 25 to 27 inches in length.
The Door and Access Systems Manufacturers Association publishes sizing tables matching door weight to wire gauge and spring length. The 0.243 inch wire spec for an average 9x7 yields an effective working stress that gives the standard ten thousand cycle rating with comfortable headroom for cold-weather contraction and routine wear.
Cost breakdown on a 9x7 job
Parts: $40 to $80 for the single torsion spring. Labor: $100 to $180 for the swap including a balance test, cable inspection, and basic opener limit check. Dispatch and travel: $25 to $50, often rolled into the labor line. All-in: $175 to $325 for a like-for-like job.
High-cycle upgrade: add $40 to $80, takes the spring from a 10,000 cycle rating to a 25,000 to 50,000 cycle rating. Cable replacement: add $30 to $60 per side. Opener limit reset and balance recalibration: add $30 to $50 if itemised. Same-day or after-hours: add $50 to $150. New rollers (nylon, quieter): add $40 to $80.
The 9x7 conversion question
Some 9x7 owners ask whether to convert from a single spring to a pair during the failure call. For a standard uninsulated or lightly insulated 9x7, conversion is unnecessary. The single spring is correctly sized for the door weight. The conversion premium of $200 to $300 buys no meaningful life extension on a door this light. Converting to a single high-cycle spring (a $40 to $80 premium) is the better choice.
The exception is a heavy insulated 9x7 (over 200 pounds) where the original installer fitted a single spring that is working close to its maximum stress. For those doors, conversion to a pair extends life and reduces the failure risk. The technician should weigh the door at the start of the call and propose conversion only if the weight justifies it.
Cold-weather failure pattern
9x7 spring failures cluster in January and February in cold-climate regions. Steel contracts as temperature drops, which adds tension to the already-wound spring. A spring that survived an October cycle at full tension can fail on a 10 degree Fahrenheit January morning. National service-call data from the larger franchises (which publish dispatch volume seasonally) shows a 30 to 50 percent spike in spring calls during the first hard cold snap of winter in the Midwest, Northeast, and Mountain West.
Homeowners in those regions who have a spring nearing the end of its rated life (six or more years on a standard cycle spring) are better off booking a preventative replacement in October or November before the cold-weather spike rather than waiting for the January failure that requires same-day service at a premium.
What to ask the technician
- What wire gauge are you fitting and does it match my door weight?
- Are you replacing only the failed spring or do you recommend pair conversion?
- Will you do a balance test and cable inspection?
- What is the parts warranty (3 to 10 years on residential)?
- What is the labor warranty (1 year minimum)?
- Is the high-cycle upgrade worth it for my usage pattern?

Frequently Asked
Why is 9x7 the most common garage door size?
9 feet wide by 7 feet tall is the smallest single-car door size that comfortably accommodates a full-size pickup truck or a mid-size SUV with mirrors extended. The size has been the suburban single-car default since the 1970s, and every major North American manufacturer stocks it as a standard SKU.
What does it cost to replace a spring on a 9x7 door?
Expect $175 to $325 installed in 2026 for a like-for-like replacement on a standard residential 9x7 single-car door. The mid-point is roughly $235 for a single torsion spring at the 0.243 inch wire gauge most installers default to for this size.
Should a 9x7 door have one spring or two?
Most uninsulated and lightly insulated 9x7 doors run on a single torsion spring, which is the correct configuration. Insulated steel 9x7 doors weighing more than 200 pounds (less common but they exist) should run on a pair. The technician should weigh or estimate the door before specifying the spring count.
What wire gauge is correct for a 9x7 door?
For a standard uninsulated 9x7 weighing 140 to 170 pounds, 0.243 inch wire on a 2 inch inside diameter torsion spring is the default. For lightly insulated 9x7 doors at 175 to 200 pounds, 0.250 inch wire is more common. The technician will know from experience or by weighing the door at the start of the call.
Why is my 9x7 quote higher than the headline range?
Common reasons include high-cycle spring upgrade ($40 to $80), cable replacement ($30 to $60), opener limit reset ($30 to $50), after-hours or weekend service ($50 to $150), or an unexpectedly heavy door requiring a heavier wire spring. If the quote spikes well past the headline range without a clear reason, ask for an itemised breakdown.
