Garage Door Spring Cost in Longmont, CO — What Homeowners Should Expect in 2026

If your garage door spring has snapped or is showing signs of wear, the first question most homeowners ask is: “How much is this going to cost me?”

It’s a fair question. And the honest answer is — it depends on a few key factors. At Mike’s Garage Door Repair and Service, we believe in transparent pricing. No surprises, no upselling. So in this guide, we’re breaking down everything that affects garage door spring cost in Longmont, CO, so you can make a confident, informed decision before you pick up the phone.

What Affects Garage Door Spring Cost?

Not every spring replacement job is the same. Here’s what drives the price up or down:

Type of spring — Torsion springs (mounted above the door) and extension springs (running along the sides) have different price points. Torsion springs cost more but last longer and are considered the safer, more reliable option.

Number of springs — Single-car garages typically use one torsion spring or two extension springs. Double-car garages often use two torsion springs. Replacing both at once is always recommended — and usually more cost-effective than doing them separately.

Spring size and weight rating — Heavier doors require heavier-duty springs, which cost more. The material of your door — steel, wood, fiberglass — directly affects which spring is needed.

Labor — Spring replacement is a skilled job that requires proper tools and safety training. Labor is part of every honest quote, and in Longmont, it typically reflects the technician’s experience and response time.

Garage Door Spring Cost Breakdown — Longmont, CO (2026)

Here’s a realistic look at what you can expect to pay for spring-related work in the Longmont area:

Service	Estimated Cost
Single extension spring replacement	$95 – $175
Pair of extension springs	$150 – $250
Single torsion spring replacement	$150 – $250
Two torsion springs (double door)	$225 – $375
Spring + cable replacement (combo)	$200 – $400
Emergency / same-day service	Add $50 – $100

These are honest, realistic ranges for the Longmont and Boulder County area. Be cautious of quotes significantly below these numbers — low-cost springs often use lower-cycle parts that fail faster and end up costing more in the long run.

Torsion Spring vs Extension Spring — Which Costs More and Why?

This is one of the most common questions we hear at Mike’s Garage Door Repair and Service.

Torsion springs sit above the door on a horizontal bar. They’re wound tightly and use torque to lift and lower the door. They’re more expensive upfront — typically $150 to $250 for a single spring — but they last longer (up to 15,000–20,000 cycles with high-cycle options) and are mechanically safer when they break.

Extension springs run along the horizontal tracks on either side of the door. They’re less expensive individually, usually $95 to $175 per spring, but most systems use two. They also require safety cables to contain the spring if it snaps, which adds a small cost if not already installed.

For most Longmont homeowners with newer garage doors, torsion springs are the standard. For older homes, extension springs are more common.

Is It Worth Replacing Both Springs at Once?

Yes — almost always.

If one spring has broken, the other one has experienced the same amount of wear over the same number of cycles. It’s close behind. Replacing both at the same time means:

• One service call instead of two
• Consistent tension on both sides of the door
• No imbalanced lifting that strains your opener
• Lower total cost compared to two separate visits

At Mike’s Garage Door Repair and Service, we always recommend replacing springs in pairs for double-door systems. It saves Longmont homeowners money and headaches down the road.

How Colorado’s Climate Affects Spring Lifespan (and Your Costs)

Here in Longmont, our winters aren’t kind to garage door springs. Metal contracts in cold temperatures and expands in heat — and Colorado’s dramatic seasonal swings put repeated stress on spring coils over time.

What this means practically: springs in Longmont may wear out faster than the national average of 10,000 cycles suggests. Lubrication every three to six months — especially before winter — can extend spring life and delay replacement costs. We recommend a garage door lubricant spray on the spring coils, not WD-40, which can actually strip protective coatings.

Annual inspections are a smart investment. Catching a weakening spring early costs far less than an emergency replacement after a complete snap.

DIY vs Professional Spring Replacement — A Real Cost Comparison

You can find replacement springs online for $30 to $80. So why not do it yourself?

Here’s the honest reality: torsion springs are wound under hundreds of pounds of tension. Releasing or winding that tension without proper winding bars and training is genuinely dangerous. Every year, homeowners across the country suffer serious injuries — broken bones, lacerations, worse — attempting DIY spring replacement.

Beyond safety, improper installation leads to:

• Unbalanced doors that damage openers
• Incorrect spring sizing that fails prematurely
• Voided warranties on openers and door systems

The $30 you save on the spring itself rarely covers the cost of what goes wrong afterward. Professional replacement by Mike’s Garage Door Repair and Service means the job is done right, safely, with the correct parts — and backed by our service guarantee.
