How much does garage door spring replacement cost in King County, WA?

Signs your garage door spring is broken

A broken torsion spring is the most common garage door emergency we see in Seattle, Renton, Kent and the surrounding cities. The typical signs are:

• A loud bang from the garage.
• A door that only opens a few inches and stops.
• A visible gap in the spring above the door.
• An opener that strains and gives up.

Should you replace one garage door spring or both?

If your door has two torsion springs and one breaks, we recommend replacing both. Springs are rated for a set number of cycles, and both springs on the same door have done the same work. Replacing only the broken one usually means a second service call within months. Replacing both at the same time costs less than two separate visits.

What affects garage door spring replacement cost

A single 8x7 door usually runs on one spring. A double 16x7 door, especially an insulated door or one with windows, is heavier and typically needs two springs of a higher rating. Doors with a high lift conversion or a custom track setup need springs matched to that specific setup. We carry the common sizes on the truck, so most homes in King County get fixed in the first visit.

We offer a free 15 minute inspection before any repair, so you know exactly what the job is before we start. Full details are on our spring replacement page, and if other parts turn out to be involved, our garage door repair service covers them.

How to compare two spring quotes

The number at the bottom of a quote is the least useful part of it, because two companies can quote the same job and be selling very different work. These are the four questions that explain almost every price difference, and any honest company will answer them on the phone.

• What cycle rating is the spring? Industry design practice is a minimum of 10,000 cycles, where one cycle is one open and one close. A household running four to six cycles a day gets somewhere around five years out of that. A high cycle spring costs more up front and lasts considerably longer, so a cheap quote and an expensive one may simply be two different lifespans.
• One spring or both? On a two spring door the second one has done the same work and is the same age as the one that just failed. Replacing only the broken one is cheaper today and usually means a second call out later.
• Are cables, drums and bearings included? A spring rarely fails on its own. If they are not in the quote, find out whether that is because they were inspected and are fine, or because they were not looked at.
• Is the quote in writing before the work starts? This is the one that protects you. A price agreed in writing cannot grow once the door is in pieces.

We put our own answer to all four in writing at the door, before anything is touched, and the estimate is free whether or not you go ahead.

Frequently asked questions

How much does garage door spring replacement cost in King County?

Every garage door spring replacement is quoted as one flat, upfront price before any work starts. The price depends on whether your door uses one spring or two, the size and weight of the door, and whether the cables or drums also need replacing.

How long does a garage door spring replacement take?

Most spring jobs are finished in a single visit, often the same day you call, because we carry the common spring sizes on the truck.

Is it cheaper to replace both garage door springs at once?

On a door with two springs, yes. Both springs have done the same work, so replacing only the broken one usually means a second service call within months. Replacing both at the same time costs less than two separate visits.
