Why Atherton homes need spring repair done right

Because Atherton doors are heavy, their springs carry more tension and reach the end of their cycle life sooner, especially on estates where the door opens dozens of times a day for staff, deliveries and family. We replace springs in pairs and offer high-cycle upgrades rated for roughly double the lifespan — genuinely worth it on a heavy Selby Lane or Walsh Road door that you can't afford to have fail again in a year.

A garage door spring counterbalances a door that can weigh 150–400 lbs, and it stores enormous energy under tension. When it snaps you'll hear a loud bang and the door becomes a dead weight the opener can't lift. Because winding a spring is genuinely dangerous, this is the repair to leave to a certified technician — we carry a full range of torsion and extension springs and replace them safely, in pairs, the same day.

What to expect on your Atherton visit

1
Identify the spring system
Torsion (shaft above the door) and extension (along the tracks) springs are sized to your door's exact weight, height and cycle needs — we measure wire size, length and inside diameter to match.
2
Replace in pairs
When one spring breaks its twin is near the end of the same cycle life. Replacing both prevents a second failure and repeat call-out, and keeps the door balanced.
3
Upgrade option
We offer high-cycle springs rated for roughly double the lifespan — worth it on heavy custom doors or homes that cycle the door many times a day.
4
Balance & safety test
We wind to the correct tension, confirm the door holds at mid-travel, re-check the safety cables, and verify smooth, quiet operation.

Spring Repair in Atherton — FAQs

Should I upgrade to high-cycle springs on my Atherton estate door?

Usually yes, if the door is heavy or cycles many times a day. High-cycle springs roughly double the lifespan, which on a custom Atherton door means far fewer service calls over the years.

You'll match the exact springs my custom door needs?

Yes. We measure wire size, length and inside diameter and size the springs to your door's real weight and height — critical on Atherton's oversized and custom doors, where a generic spring simply won't balance the door.

Why shouldn't I replace a garage door spring myself?

A wound torsion spring stores enough energy to cause serious injury if a winding bar slips. Correct wire size, tension and safety-cable setup all matter. This is the repair where a professional is genuinely safer — and usually faster.

Should I replace both springs if only one broke?

Yes, we recommend it. Both springs share the same cycle life, so a broken one means the other is close behind. Replacing the pair keeps the door balanced and avoids a second failure within months.

How long do garage door springs last?

A standard spring is rated for about 10,000 cycles — roughly 7–12 years for an average household, but far less if the door opens many times a day. High-cycle springs roughly double that.

Can you come out today for a broken spring?

Yes — a broken spring is our most common same-day and emergency call. We stock a wide range of spring sizes on the truck so we can measure and replace on the first visit.

“A spring snapped on our custom wood door the night before we were hosting. They came out the next morning, matched the high-cycle springs it actually needed, and had it running silently by noon. Discreet, precise, no upsell.”
