Garage Door Spring Replacement in Portland, ME
Springs are what actually lift your garage door — the opener just guides it. When a spring breaks, the door becomes dangerously heavy and the opener can't move it safely. Spring replacement is one of the most common calls we get, and it's not a DIY job given the stored tension involved.

When to Call
When You Need Garage Door Spring Replacement
- Heard a loud bang from the garage and the door won't open now
- Opener runs but the door barely lifts off the ground
- Can see a visible gap or separation in the coil spring above the door
- Door feels extremely heavy when you try to lift it manually
- One side of the door rises faster than the other when opening
- Springs are original to a door that's over fifteen years old
How It Works
Our Process for Garage Door Spring Replacement
- 1
Call assessment
We ask whether the door is stuck open or closed, and whether there's a visible break. That tells us what parts to bring and how urgent the visit is.
- 2
Spring identification
We measure the existing spring — wire diameter, inside diameter, length — to spec the correct replacement. Wrong-sized springs wear fast and stress the opener.
- 3
Safe removal
We release residual tension from the old spring using the correct winding bars. This is where injuries happen when people try this themselves. We don't rush it.
- 4
Installation and winding
New spring goes on, then we wind it to the correct turn count for your door's weight. This sets the lift balance. Getting this wrong shows immediately.
- 5
Balance test
We disconnect the opener and lift the door by hand to mid-height. It should hold there on its own. If it doesn't, we adjust tension before reconnecting.
- 6
Full system check
We reconnect the opener, run several cycles, and check cable alignment. A spring replacement is also a good time to catch cables or rollers showing wear.
What's included
- Measurement and specification of correct replacement spring
- Removal of broken spring with proper tension-release procedure
- Installation and winding of new spring to correct turn count
- Door balance test with opener disconnected
- Cable condition check during the same visit
- Full cycle test with opener reconnected before leaving
What's not included
- Cable replacement if cables are also damaged — that adds scope and parts
- Replacement of both springs if only one is broken, unless you request it
- Opener repairs if the opener was damaged by running against a locked-heavy door
Real Situations
Common Scenarios in Portland
A homeowner in Deering hears a loud crack early in the morning and finds the garage door stuck closed with the car inside.
We get there, confirm the torsion spring snapped, and measure for the correct replacement. We can usually get the door manually lifted and propped so they can get the car out while we work. Spring is replaced and the door is balanced before we leave.
A Cape Elizabeth homeowner's door has been struggling for months and the opener recently started making a grinding noise under load.
We find the spring has lost most of its tension without fully breaking — the opener has been working against a heavy door for a while. We replace the spring, check opener strain, and test balance. The opener strain issue gets documented so they know what to watch.
A landlord in Munjoy Hill has a tenant reporting the door only opens halfway before stopping.
The opener's safety mechanism is cutting out because the door is too heavy on a weakened spring. We replace the spring, set correct tension, and confirm the opener runs through its full cycle without cutting out.
Portland Context
Why this matters in Portland
Maine's temperature swings are hard on spring steel. A spring that was installed when the garage was built in the 1990s has been through thirty winters of contraction and expansion. In Portland especially, where a lot of garages face north or get little sun, springs tend to go brittle and fatigue faster than in milder climates.
Straight Talk
About pricing & scope
Spring pricing depends on the spring type — torsion versus extension — and the size required for your door's weight. Heavier two-car doors need heavier springs, which cost more. If the cables show fraying during the job, we'll flag it and let you decide whether to add that repair.
