GARAGE DOOR SPRING REPLACEMENT

A standard oil-tempered torsion spring is rated for about 10,000 cycles, and a household opening and closing the door four times a day reaches that limit in roughly 7 years. Sonoma Overhead Doors and Gates handles garage door spring replacement from Sonoma, CA out to Novato, Napa, and Mill Valley, covering Napa, Sonoma, and Marin Counties. We measure wire size, inside diameter, and length, calculate the correct spring for your door's actual weight, and replace torsion or extension springs in matched pairs. High-cycle upgrades rated for far longer service are available, and every replacement finishes with a full balance and safety test before we leave.

BROKEN SPRINGS STOP EVERYTHING AT ONCE.

Most people discover a broken spring the hard way: a loud bang from the garage, followed by a door that barely moves or an opener that hums and gives up. Cars get trapped, schedules fall apart, and the door becomes dangerous to operate. We carry a wide range of springs on our trucks so most replacements happen during the first visit.


We measure the old spring and weigh the door rather than guessing from a label, because correct sizing is what makes the new springs last and keeps the opener from straining every cycle.

GARAGE DOOR SPRING REPLACEMENT

THE RIGHT SPRING, SIZED FOR YOUR DOOR, INSTALLED SAFELY.

Every door has a specific weight, height, and drum setup, and the springs must match all three. We calculate the proper wire gauge and length, remove the broken spring and its partner with controlled tension release, and install the new pair using proper winding bars. After winding to the correct number of turns, we fine-tune balance, lubricate the new springs, and test the door through repeated cycles to confirm smooth, safe travel.
SPRINGS THAT STAND UP TO NORTH BAY MORNINGS.
Cold snaps, damp fog, and salt air all speed up spring fatigue. Around Marin and the Petaluma Gap, we often recommend galvanized or coated springs that resist rust better than bare oil-tempered steel. Busy households and small businesses in Sonoma and Napa that cycle their doors often benefit from high-cycle springs that last years longer. We match the recommendation to your climate and usage, not to a single default product.
OUR TRUCKS ROLL OUT LOADED WITH SPRINGS FOR A REASON.
Broken springs are one of the most common calls we receive, and after 25+ years, we know that waiting days for parts is the last thing anyone wants. That is why our service vehicles carry a broad stock of common spring sizes. Combined with careful measuring, it means your door is usually back in service the same day.

A Door That Works Again
New springs restore lifting power immediately. Cars, tools, and equipment are no longer trapped, and daily routines return to normal without waiting on a stuck or dangerous door.

Even, Reliable Balance
Replacing both springs together keeps tension equal on each side. The door lifts straight, travels steadily, and closes gently rather than leaning, jerking, or slamming onto the floor.

Longer Service With High-Cycle Options
High-cycle springs rated for 25,000 cycles or more can last several times longer than standard ones. For busy households and businesses, that means far fewer replacements over the life of the door.

Protection for the Opener
Correctly sized springs carry the door weight, keeping stress off the opener motor and gears. Your opener runs cooler and quieter and avoids premature failure caused by an unbalanced load.

Improved Household Safety
Worn springs can snap unexpectedly and leave the door unsupported. Fresh springs, installed and tensioned properly, reduce the risk of sudden drops that could injure someone or damage a vehicle.

Better Corrosion Resistance
Choosing galvanized or coated springs for damp locations slows rust and pitting. Your new springs keep their strength longer and stay quieter in fog-prone neighborhoods across the North Bay.

I am so happy with the service and the garage doors that we purchased from Sonoma Overhead Doors. Marty was so knowledgeable on the different products and helpful. We had the panels custom painted to match the house.



The motors are so quiet that you hardly hear them. I couldn't be more pleased with this company and would recommend them to anyone.

Very happy! They were able rectify an install that was incompatible with existing equipment and provide competitive pricing for a new unit and install. The installer was even able to have the unit welding mesh with the existing design.

FAQ

FREQUENTLY ASKED QUESTIONS.

A broken spring brings immediate questions about safety, timing, and whether both springs need replacing. These answers cover what homeowners ask us most when a spring suddenly fails.

    Should I replace both garage door springs at the same time?

    Yes, in most cases. Both springs have completed the same number of cycles, so the second is usually close to failing. Replacing them together keeps tension balanced and saves you a second service call soon after.


    How long do garage door springs last?

    Standard torsion springs are typically rated for about 10,000 cycles, which is roughly 7 years for a door used four times daily. High-cycle springs can last several times longer with the same usage.


    What size spring does my garage door need?

    Spring size depends on door weight, height, and drum type, measured by wire gauge, inside diameter, and length. Guessing leads to imbalance, so we measure the old spring and verify door weight before choosing.


    Why did my garage door spring break?

    Springs fail from metal fatigue after thousands of cycles, and rust, cold temperatures, and lack of lubrication speed the process. An unbalanced door or an undersized spring also wears out faster than it should.


    Will my opener still lift the door if only one spring broke?

    It is not safe. The remaining spring cannot balance the door, and the opener or cables may fail under the extra load. Keep the door closed and schedule spring replacement as soon as possible.


    Are high-cycle springs worth the extra cost?

    For doors used frequently, yes. High-cycle springs often cost only modestly more but can last several times longer, which lowers the cost per year of service and reduces the chance of future breakdowns.


    Does Sonoma Overhead Doors and Gates carry springs on the truck?

    Yes. Sonoma Overhead Doors and Gates stocks common torsion and extension spring sizes on service trucks, so most spring replacements in Sonoma, CA and nearby communities are completed during the first visit.


    Why choose Sonoma Overhead Doors and Gates for spring replacement?

    Matched pairs, careful measuring, and predictable costs. Sonoma Overhead Doors and Gates has replaced springs in Sonoma, CA for 25+ years and sizes every new spring to the door rather than a guess.

    HOW WE WORK

    Step-01

    WE SECURE THE DOOR
    Our very first step is making sure the door cannot fall. We clamp it in place, disconnect the opener, and assess the broken spring and surrounding hardware before handling any remaining tension.

    Step-02

    WE MEASURE PRECISELY
    We measure wire size, inside diameter, and length on the old spring and check the door's actual weight and height. Those figures determine the exact spring your door needs for proper balance.

    Step-03

    WE RELEASE OLD TENSION
    The partner spring still holds tension, so we unwind it slowly and carefully with proper bars. Both old springs come off the torsion tube safely, and we inspect the cones, bearings, and drums.

    Step-04

    WE INSTALL THE NEW PAIR
    New springs are mounted on the torsion tube and wound to the calculated number of turns. Cables are checked for even tension, and set screws are tightened securely on each winding cone.

    Step-05

    WE BALANCE THE DOOR
    With the springs set, we lift the door by hand and stop it at several heights. Small tension adjustments continue until it holds steady halfway and lifts easily without help from the opener.

    Step-06

    WE TEST EVERYTHING
    We reconnect the opener, run full cycles, and check reversal and photo eyes. The springs are lubricated, and you receive simple tips for recognizing wear so you can plan ahead next time.
