A spring matched to your door
Wire size, inside diameter, length and wind direction all have to suit the weight and height of the actual door. Two springs that look alike from the driveway can be rated completely differently.
Springs carry almost the entire weight of the door, so when one lets go the opener is suddenly trying to lift a slab of steel on its own. An independent provider can secure the door, replace the spring with a correctly rated match and check everything the failure put under strain.
Springs are rated in cycles, and one cycle is one trip up and one trip down. In a Gilbert household where the garage is the main way in and out, a door can run through those cycles years earlier than a homeowner expects, which is why a spring can fail on a door that still looks new from the street.

Not every visit needs every item. Ask the provider which work is repair and which is optional, and to separate the two in the quote.

A failing spring puts load through cables, drums, bearings, the shaft and the mounting plate. Those get inspected while the system is apart, because replacing the spring alone can leave the next weak link in place.
Once the new spring is set, the door should hold its position part way up without the opener helping. The opener's force settings and auto-reverse are checked afterwards so the motor is not compensating for a door that is still out of balance.
Where a door has two springs and only one has broken, ask the provider what they recommend about the second. Both have taken the same number of cycles and the same summer heat, so a second failure in the months ahead is a fair thing to plan for rather than a sales line. The quote should say clearly which springs are being replaced and why.
If the same door has also been through cable and roller work or the opener has been struggling for a while, it is worth reading the repair versus replacement guide before you approve a string of separate repairs.
Spring repair referrals cover Gilbert and the wider area, including Higley and Queen Creek. Check the full list on the service areas page.
The size and rating of the spring your door needs, whether one or both are being replaced, and whether the cables, drums or bearings were damaged when it failed. Ask an independent provider to inspect first and give you the figure before the work starts.
Availability depends on the provider and the property location. Common residential spring sizes are often stocked, so many repairs finish in one appointment; an oversized or unusual door may need a spring ordered in, so ask at the inspection.
No. With a broken spring, that door can weigh well over a hundred pounds and there is nothing holding it up if it slips. Leave it closed, keep the car and the family out of the opening, and do not pull the red release handle while the door is part way up.
On a two-spring door it is worth discussing. Both have done the same work in the same heat, so the second is usually close behind the first. Ask the provider to price both options so you can choose rather than having it decided for you.
