What exactly does your warranty cover on a new garage door installation?

Our warranty typically covers the door panel itself for 10 years against manufacturing defects, springs and hardware for 5 years, and labor for 1 year from installation. Weather seals and weatherstripping are covered for 3 years. Damage from extreme weather events, lack of maintenance, or accidents isn't included. We'll walk you through the specifics when you choose your door—every manufacturer's coverage differs slightly, so it's worth discussing your particular situation upfront.

How can I tell if my garage door springs are actually broken, or if something else is wrong?

A broken spring usually means your door won't open at all, or it crashes down suddenly—that's the giveaway. If your door opens partway and stops, or moves slowly and unevenly, the opener or cables might be the culprit instead. Listen for a loud bang when the door closes; that's often a spring snapping. Don't try to open a door with a broken spring manually—the tension is dangerous. Call us and we'll diagnose it safely.

If my door gets stuck off-track, how quickly can you get here?

For off-track emergencies on Mercer Island, we typically respond within 1–2 hours during business hours. We prioritize these calls because a stuck door blocks your driveway and can pose safety risks. If it happens after hours, we do offer emergency service—response time depends on the time of night, but we'll give you an honest estimate when you call. Getting it back on track usually takes 30–45 minutes once we arrive.

How do I know if my garage door opener is powerful enough for my door?

Opener horsepower should match your door's weight and material. A standard single-car steel door needs a ½ HP opener; heavier wood or double-car doors often require ¾ or 1 HP. If your opener struggles to lift the door, cycles on and off oddly, or barely moves it, it's undersized. We'll measure your door, check its balance, and recommend the right opener—oversizing doesn't hurt and actually extends opener life by reducing strain.

My garage door won't stay closed. Is it worth repairing or should I replace the whole thing?

If the door is 10+ years old and showing multiple issues—dents, rust, worn panels, plus mechanical problems—replacement often makes more sense financially and safety-wise. Newer doors are more insulated and secure. But if your door is structurally sound and just needs new springs, cables, or an opener, repair is absolutely the right move. We'll inspect yours and give you honest advice, not a sales pitch.

Do I need HOA approval before replacing my garage door on Mercer Island?

Many Mercer Island neighborhoods do have HOA guidelines about garage door appearance and size, especially in areas with consistent architectural styles. Some restrict color or material choices. We recommend checking your HOA documents or calling your management company before ordering a new door. If you're unsure, bring us your current door specs and we can help you navigate options that'll likely get approval—we work with local HOAs regularly.

My safety sensors aren't working. Do I need to replace them or just realign them?

Safety sensors often just need realignment—dust, debris, or a slight bump can throw them out of sync. We'll check the alignment and clean the lenses first; that fixes it 60% of the time. If they're physically damaged or old (10+ years), replacement is safer and inexpensive. Misaligned sensors are a real safety hazard, so don't ignore them. We'll test them under load to make sure they're functioning correctly.

How do I reprogram my garage door remote or keypad if it stops working?

First, replace the batteries—that solves most issues. If that doesn't work, your opener likely needs to be reprogrammed. The process varies by opener model; some require holding a button on the opener itself for a few seconds, others need a sequence of key presses on the pad. Your opener manual has instructions, or we can walk you through it over the phone. If the remote is old or physically damaged, a new one runs $30–60 and pairs quickly.

Garage Door Spring Replacement on Mercer Island: What You Need to Know Before the Cable Snaps

2026-04-16 7 min read

It usually happens on a Tuesday morning when you're already running late. You hit the button, the opener hums, and the door barely moves. or doesn't move at all. Nine times out of ten, a broken garage door spring is the culprit. On Mercer Island, where wet winters and temperature swings between the high 30s and low 80s put consistent stress on metal components, spring failures are one of the most frequent service calls we handle.

If you've never given your springs a second thought, you're not alone. Most homeowners don't. until they have to.

What Garage Door Springs Actually Do

Your garage door can weigh anywhere from 130 to over 400 pounds depending on whether it's a single-panel steel door, an insulated double-car door, or one of the heavier wood carriage-style doors common in neighborhoods like Mercerdale or West Mercer. Springs do the heavy lifting. literally. They store mechanical energy and counterbalance the door's weight so your opener motor only has to do a fraction of the actual work.

Without functioning springs, the opener is essentially trying to deadlift the full weight of the door on its own. That's why a broken spring often means a door that won't open at all, even with a working opener.

Two Types of Springs. and Why It Matters

Torsion springs sit horizontally above the door opening on a metal shaft. They're the standard on most modern Mercer Island homes, including the split-entry and two-story homes built through the 1970s and 80s in neighborhoods like Mercer Ridge. Torsion springs are more durable, safer when they break (they stay on the shaft), and better suited to heavier doors.

Extension springs run along the horizontal tracks on either side of the door. They're found on older homes and lighter doors. They're generally less expensive to replace, but they have a shorter lifespan and carry a higher risk when they snap. a broken extension spring can whip free with serious force if there's no safety cable running through it.

When you call for a spring inspection, the technician will assess which type you have, whether your door has single or double springs, and whether the spring specifications match the actual weight of your door. Using the wrong spring size can damage the door system and overburden the opener, leading to early breakdowns and increased repair visits.

Warning Signs Your Springs Are Failing

Don't wait for a full failure. Here's what to watch for:

- The door feels unusually heavy when you lift it manually (with the opener disengaged) - Visible gaps in a torsion spring. a clean break will look like a gap in the coil - The door opens unevenly, one side lower than the other - Loud bang from the garage. a snapping torsion spring sounds like a gunshot - Cables hanging loose alongside the door tracks - Slow or jerky operation even though the opener is running fine

If your door is struggling, don't keep cycling it. Running a garage door opener against a broken spring puts serious strain on the motor and can turn a $300 spring repair into a $500+ opener replacement.

What Does Spring Replacement Cost on Mercer Island?

In the greater Seattle area, homeowners can generally expect to pay between $200 and $800 for a spring replacement, depending on the type of spring, the weight of the door, and whether one or both springs need replacing. Torsion springs run higher than extension springs due to their complexity and durability.

One thing worth knowing: if one torsion spring has broken, the other is typically close behind. both springs are installed at the same time and wear at the same rate. Replacing both during the same service call saves you a second labor fee down the road. It's worth asking your technician about this when they're on-site.

For homes in Bellevue or Redmond where labor markets are similar to ours, pricing tends to be comparable. Get at least two quotes for any job over $500, and be cautious of any quote that exceeds $1,000 without a clear breakdown of parts and labor.

Why This Is Not a DIY Job

We'll be straight with you: garage door spring replacement is genuinely dangerous without the right tools and training. Torsion springs are wound under several hundred pounds of force. If a spring slips during winding or unwinding, the winding bars can snap back with enough force to cause serious injury. This isn't liability language. it's the reason professional technicians use specific winding bars, wear eye protection, and follow a precise sequence.

DIY spring replacement may seem cheaper initially, but it can lead to further complications and higher costs if not done correctly. A professional service also includes a door balance test after installation. something most homeowners don't know to check but that directly affects how long your opener motor lasts.

Check out our full list of garage door services if you're not sure what type of repair your door needs. springs, cables, rollers, and openers are all covered.

How Long Do Springs Last?

Most standard torsion springs are rated for 10,000 cycles. one cycle being one open and one close. For the average household using the garage door four times a day, that works out to roughly 7 years. High-cycle springs rated for 25,000,50,000 cycles cost more upfront but make sense for busy households or multi-car garages.

Island living means your garage sees year-round use. Rainy winters mean the garage becomes the main entry point for months at a time. Factor in that heavier usage when deciding whether to go standard or high-cycle on your next replacement.

If you've already had one spring failure, it's also a good time to take a broader look at your door hardware. rollers, cables, and hinges all wear at similar rates. Our spring maintenance tips in the spring preparation guide cover what to inspect on an annual basis to catch problems before they become expensive.

Reach out to schedule a spring inspection or replacement. most jobs can be completed in under two hours, and same-day service is often available for homeowners on the island.

Frequently Asked Questions

Can I still use my garage door if a spring is broken?

Technically the door may still move if the opener motor is powerful enough, but we strongly recommend against it. Running the opener against a broken spring strains the motor and can damage the opener, tracks, and cables. Disconnect the opener and leave the door in place until a technician can assess it.

Should I replace both springs at the same time?

Yes, in almost every case. Both springs are installed at the same time and experience equal wear. If one has broken, the other is statistically close to the end of its life. Replacing both during the same visit saves a second service call fee and keeps your door balanced.

How do I know if my door is properly balanced after a spring replacement?

Disconnect the opener by pulling the red emergency release cord, then manually lift the door to about waist height and let go. A properly balanced door will stay in place. If it drops or rises on its own, the spring tension needs adjustment. call your technician back before reconnecting the opener.
