The garage made a sound like a gunshot at dawn, and the door sat right where it landed. The spring is what lifts that weight, so with it gone, the door has no way to rise.
Our techs weigh the door to determine exact spring size and wire diameter for Portsmouth’s specific housing styles, perfectly adjusting coil tension.
The button does nothing, or the drive starts and the door sits frozen mid-cycle. A stripped gear, a dead logic board, or a photo eye bumped sideways is usually what we find inside.
Never pull the red release cord while the door is open or jammed. Pull it only when the door is fully closed.
One corner of the door has dropped and the whole panel tilts hard in the opening. Keep everyone clear and phone us for garage door repair Portsmouth NH rather than pushing it back yourself.
Keep people and vehicles clear until a technician secures it. Cable realignment isn't something a homeowner can do safely.
A door that will not close is a security gap you cannot leave until sunrise. We answer the phone at any hour and you speak to a live person.
You will not be charged extra for a repair when the service has already been estimated.
On every garage door repair Portsmouth NH call, the tech writes up a price for the work and waits for your approval before any tool comes out. The following points detail what work is covered.
All sizes of doors covered, broken torsion springs and extension springs replaced. Most springs kept in stock so a second trip is seldom required.
Our garage door opener repair Portsmouth NH work covers LiftMaster, Chamberlain, Genie and Craftsman openers: stripped drive gears, failed logic boards and burned-out motors.
Garage door installation Portsmouth NH covers new doors fitted with tracks, hardware and the opener of your choice. Quote given before installation.
For garage door replacement Portsmouth NH homeowners get a complete new door built to the opening and insulated the way they want.
garage door service Portsmouth NH covers the balance, the spring tension, the condition of the rollers and the hinges and includes the auto-reverse test. A written quote will be provided prior to commencing work.
Our experienced technicians travel to your warehouse, loading dock, or retail bays throughout Portsmouth to complete service calls for roll-up and sectional doors. Most parts are carried on our trucks for common door makes.
Frayed cables and bent tracks are hazards and are treated as such. Replacing cables and straightening tracks is part of any garage door repair Portsmouth NH call.
We pull the damaged panels and fit matching replacements, then install a new bottom seal so the door closes flush against the floor.
That loud bang you heard at six in the morning wasn’t the house settling. The spring snapping under load is sharp, sudden, and hard to mistake for anything else once you know what it is.
Once a spring is broken, do not run the opener. Leave the door where it is and call a technician. On a door with two springs, our technicians typically recommend replacing both at the same time.
Opener problems show up in a lot of different ways, and the symptom usually points toward the cause.
A motor that hums but doesn’t move the door is often a stripped drive gear. A door that reverses for no clear reason is frequently a photo-eye alignment issue or a sensitivity setting that’s drifted out of range. A door that opens on its own, with no one touching the remote, tends to trace back to a logic board fault or an older fixed-code remote broadcasting on the same frequency as a neighbor’s. Spring and cable work belongs to a trained technician, never a homeowner. The same goes for the drive gear and wiring inside the opener. Every repair gets a written quote before any work starts, and you decide whether to move forward. If a new drive gear is all your opener needs, that’s what we’ll tell you, rather than pushing for a full unit replacement.
On each side, a lift cable runs from the top drum to the bottom bracket. When one frays or snaps, that side of the door loses support and the whole panel goes out of alignment fast.
Before anyone touches anything, one rule applies without exception. A door that comes off track can weigh 200 pounds or more, and it can drop without warning. Bent and corroded tracks come up regularly on garage door repair Portsmouth NH calls, and salt air off the harbor is usually the reason. Steel tracks that look fine in September can be pitted and warped by February. We straighten, shim, or replace track sections depending on what the inspection turns up.
A single cracked or dented panel rarely means the whole door has to go. If the damaged panel matches a current production profile and the surrounding structure is still sound, replacing that single section is almost always the better call. Our technicians match profile and finish as closely as available stock allows.
Property managers overseeing rental units in Portsmouth find this particularly useful, because a single impact on one panel of a rental door doesn’t have to mean a full replacement.
A door stuck open at midnight should not sit until sunrise. Our 24/7 phone lines are answered live by real people.

Portsmouth is a seacoast town in many ways, with problems that an inland town of similar age would have no idea exist.
For one, there is the problem of salt in the air from the Atlantic, which over the years can corrode steel tracks and cables and even the pins of hinge over the years. We see these garage door repair Portsmouth NH calls again and again in the South End and the older streets near Prescott Park. The International Door Association publishes guidance on corrosion-resistant alternatives to the standard door hardware.
The Portsmouth area is known for lots of pre-1970s colonial homes and a multitude of triple decker homes.Read more
The older doors are generally equipped with a single spring to hold them in place. Newer very well insulated panel doors can often overload these older style doors and cause the spring to break. The garage door company Portsmouth NH homeowners call for this sees it often, and our garage door spring repair Portsmouth NH work sets a new spring to the correct weight of the door.

Garage door repair Portsmouth NH calls anchor our territory, and the trucks fan out from there to cover the seacoast towns and the communities stretching inland along Routes 4 and 101.
Whether you’re on the waterfront side of the city or out near the traffic circle on Woodbury Avenue, a technician is dispatched from the closest available location rather than from a fixed shop address. That keeps response times shorter across the whole zone. Our coverage page names each town we serve.

Because most garage door repair Portsmouth NH jobs wrap up in a single visit, and because the trucks carry parts for the most common repairs, same-day work happens more often than not.

Pricing for garage door work isn’t something we can pin down over the phone, because no two doors show up in the same condition. A garage door repair Portsmouth NH technician looks at your specific door, figures out exactly what it needs, and puts the quote in writing before anything else happens. You review the number, you say yes or no, and a tool doesn’t come off the truck until you’ve approved the price.
Nobody here gives you an all-day window and wishes you luck. When you call, the dispatcher locates the nearest available technician and gives you a firm two-hour block, not a vague stretch of time that eats your whole afternoon. Once the truck rolls toward your address, a text goes straight to your phone so you’re not left guessing.
Our trucks cover Portsmouth and spread out from there to Rye, New Castle, Newington, Greenland, and Stratham along the coast, plus Exeter, Hampton, Newmarket, and a number of towns further inland. Wondering if your street is covered? A quick call to (833) 435-4540 gets you a straight answer from the dispatcher in about thirty seconds.
Every corner of Portsmouth is covered, from the South End and Pannaway Manor to the Woodbury Avenue corridor and the neighborhoods out toward Greenland Road.

It isn’t, and here’s why. Torsion springs store a serious amount of mechanical energy, and releasing that energy without the correct winding bars and the right training can cause a severe injury in a fraction of a second. Household tools aren’t built for this job, and there’s no margin for error. Call a technician instead.
On a door fitted with two springs, our technicians recommend swapping both at once, and the reason is straightforward. Both springs have been through the same number of cycles, so when one snaps the other is usually close behind. Replacing both in a single visit usually saves a second call soon after for the other spring. You’ll hear that recommendation before any work begins, and the choice is always yours.
Commercial work is a regular part of what we do here. Our techs handle rolling steel doors, sectional overhead doors and high-cycle spring systems. Property managers, warehouse operators, and small business owners all go through the same process: the technician inspects the door, writes up the quote, and waits for your approval before starting anything.
A tune-up call covers spring tension, door balance, roller and hinge condition, the auto-reverse safety function, and the bottom seal, which takes a real beating from Portsmouth winters and salt air off the Piscataqua. Catching a worn roller or a fraying cable in March is a lot easier than dealing with a door that won’t move on a cold November morning.
A door that opens on its own usually points to one of a handful of causes: a shorted wall button, a wiring fault in the control circuit, a failing logic board, or an old fixed-code remote from a neighbor accidentally triggering your system. We track down the actual cause on a garage door repair Portsmouth NH call rather than just resetting the unit and hoping for the best.
A broken spring, a door partially open or an opener not functioning can occur at any time. We provide 24 hour coverage for all garage door repair Portsmouth NH brands and you will always speak with a live person answering the phone. Contact Century Garage Door Repair Service for a written quote and (833) 435-4540 will send a qualified service technician to your Portsmouth home or business within the greater seacoast area.
