When your garage door won't open in Dover, you need help fast. Loudon Garage Doors serves Dover from our Loudon base, typically reaching you in 36 to 54 minutes depending on traffic. We've been fixing broken springs, installing new openers, and handling emergency repairs throughout Dover for years, and we know exactly what local homeowners face when a door fails.
Dover's housing stock ranges from historic homes near downtown to newer developments in areas like the Garrison Hill and Silver Street neighborhoods. Older homes often have original garage doors that weren't built for today's daily use patterns, while newer construction sometimes includes builder-grade doors that need upgrades after a few years. Both situations create regular repair needs.
New Hampshire weather hits garage doors hard. Freezing temperatures make metal contract, which stresses springs that are already handling 400-plus pounds of door weight. Springs typically last 7 to 9 years with normal use, not the 10 years some manufacturers claim. When humidity rolls in during summer, wooden doors swell and metal parts can rust if they're not properly maintained.
Dover homeowners call us most often for broken springs, which usually fail during cold snaps. You'll hear a loud bang from the garage, and suddenly the door won't budge or the opener strains without lifting anything. Cables fray, rollers crack, and opener gears strip out over time. These aren't DIY fixes. A loaded spring under tension can cause serious injury if mishandled.
Our Dover garage door service covers everything from quick fixes to complete replacements. Spring replacement is our most common call. We carry residential torsion springs on every truck, so most jobs finish in under an hour. We replace both springs even if only one broke, because the second one is usually just as worn and will fail soon anyway.
Opener installation is straightforward when you work with quality brands. We install LiftMaster, Chamberlain, and Genie models, and we'll help you choose between chain, belt, or screw drive based on your garage layout and noise tolerance. Belt drives cost more upfront but run quieter, which matters if you have living space above the garage.
Cable and roller repair often gets overlooked until something jams. Frayed cables can snap, and worn rollers make the door shake and grind. We replace these components before they cause bigger problems. Full door replacement makes sense when repair costs approach half the price of a new door, or when you're upgrading insulation values for an attached garage.
Maintenance plans keep everything running smoothly. Annual service includes lubricating moving parts, testing safety sensors, checking spring tension, and adjusting track alignment. Request a maintenance quote for any Dover ZIP code.

"Spring broke on a Saturday morning and my car was trapped inside. They had someone here in 90 minutes and fixed it in 45. Fair price, no weekend gouging. Explained what happened and why both springs needed replacement." . Tom R., Garrison Hill
"Our 15-year-old opener finally died. Technician showed us three options at different price points without pushing the expensive one. Installation was clean, showed us all the safety features, and programmed our car remotes before leaving." . Patricia M., Dover
How fast can you get to Dover from Loudon?
The drive from our Loudon shop to Dover typically takes 36 to 54 minutes depending on route and traffic conditions. We usually take Route 4 to the Spaulding Turnpike, which is the most reliable path. For same-day service, calling before noon gives us the best chance to fit you in that afternoon.
Do you carry parts for older garage door models?
We stock common springs, rollers, cables, and hardware that fit most residential doors from the past 20 years. For specialty parts on older or custom doors, we can usually source them within a day or two. Sometimes we'll retrofit modern components that work better than the original parts and are easier to service long term.
What's the difference between torsion and extension springs?
Torsion springs mount on a bar above the closed door and twist to lift the weight. Extension springs run along the horizontal tracks and stretch when the door closes. Torsion systems are safer, last longer, and work better, which is why most modern doors use them. We can convert extension spring systems to torsion during replacement.
How much does garage door repair cost in Dover?
Spring replacement typically runs $225 to $375 depending on door size and spring type. Opener installation ranges from $350 to $650 including the unit. Simple fixes like sensor alignment or remote programming cost much less, often under $100. Every situation is different, so we always diagnose first and quote before starting work.
