Garage Door Spring Replacement
A broken torsion or extension spring leaves the door dead weight and unsafe to force. Springs are replaced in matched, correctly rated pairs and the door is rebalanced and tested — same day. In Dover, springs are rated for the door and fitted in pairs, because a single new spring beside a winter-worn one lifts unevenly. For garage door spring replacement in Dover, NH, one call books the visit and a local tech takes it from there.

Winter in Dover is long and hard, the housing stock is old, and many garages are unheated and uninsulated. This is what we actually find here, and what we check on every visit.
Spring steel loses flexibility in deep cold, and a Dover spring near the end of its cycle life often chooses a freezing morning to snap - usually with a bang loud enough to hear inside the house. A door that suddenly feels impossibly heavy has lost a spring, not its opener.
Salt tracked in on tires all winter sits in the lower track and on cable strands across Dover, and it corrodes exactly the parts that carry the door. Cables fray from the bottom up here, and hinges stiffen until the opener has to drag the door open.
Wet snow pushed against the door, ice built up in the track path and frozen slush at the threshold all change how a Dover door travels. Rollers climb over ice, bind, and occasionally leave the track entirely, leaving the door hanging crooked.
Water in the frame and track anchors freezes, expands and shifts alignment a little further every cycle across New Hampshire. By late winter the evidence is a door that scrapes, a gap at one corner, and an opener reversing for no obvious reason.

Every Dover visit runs the same way — booked in one call, diagnosed at the door, and finished with the door cycled and tested in front of you.
Call (888) 259-9830 and tell us what the door is doing — a snapped spring, a dead opener, a door off its tracks, or one that has just got loud. We book a local Dover tech, same day whenever a slot is open.
The visit starts with the whole system checked — springs, cables, rollers, tracks and the opener — so the diagnosis is clear before any work begins, and the inspection is free.
The repair is done with the right parts on the truck, the door rebalanced and the opener set back to its proper force and travel — residential doors only, done the way we would want our own done.
You watch the door run a full cycle — up, down, safety reverse tested, the doorway completely clear — and any work was priced and agreed before it began. Estimates are always free.
5 stars — based on 100+ reviews. Dover homeowners rate We Garage Door five stars across Google and Facebook, and they mention the same things: the free inspection, the same-day repair, and a door that runs smooth, balanced and quiet when we leave. Call (888) 259-9830 and put us to the same test.
Do not keep running the opener: a door bonded to the floor by ice can tear its bottom seal or strain the motor and top panel. Warm water along the seal frees most frozen doors in Dover. If it still will not move, or it moved and now runs crooked, have it checked - ice in the track bends hardware.
Most often a broken spring: the opener can start the lift but cannot carry the full weight once the balance point passes. In a Dover winter it can also be the door binding on ice in the track. Either way, stop cycling the opener and have it looked at before the motor pays for it.
If the springs are intact, yes: pull the red cord with the door closed and lift steadily - it should rise and hold position. If it feels like lifting the heavy end of a piano, a spring is gone. Stop there; a full-weight door in Strafford County winter cold is not a hand-lifting job.
Usually a slow bump from a car - easy on an icy driveway in Dover - or a cable frayed through by road salt letting one side drop. Leave an off-track door exactly as it is, keep everyone clear, and call: the door is under spring tension and pushing it makes things worse.
Late summer or early fall, before the cold arrives. Every neglected door in Strafford County seems to fail the same week in January, and that is when schedules fill. A safety inspection in September means the first freezing morning is routine instead of a trapped car.
No — and be wary of anyone who does. Every garage door fails differently, so a phone price is a guess that changes at your door. Our estimates are free: a tech looks at the actual door, springs and opener, then gives you one clear price before any work starts.
