Common Garage Door Problems We Fix
With over 35 years of experience, our team has seen and solved virtually every garage door issue imaginable. We handle a wide range of repairs, including:
Broken torsion and extension springs

Malfunctioning openers and remotes

Garage Door Spring Repair
Safe, Precise Spring Replacement
Broken or worn-out springs are one of the most common — and dangerous — garage door issues. Springs bear the weight of the door, and when they fail, the system becomes unsafe and difficult to operate.
Our trained technicians specialize in garage door spring repair in Dover, NH, using industry-approved tools and techniques to replace springs safely. We carefully match each spring to the correct size and tension for your door’s make and model, ensuring smooth, balanced operation after installation.
We strongly advise homeowners not to attempt spring replacement themselves, as improper handling can cause serious injury. Let our professionals handle the work safely and efficiently.
Garage Door Opener and Sensor Repair
A faulty garage door opener can leave you stuck inside or outside your home at the worst possible time. At Duplouy Enterprises LLC, we repair and replace all types of openers, including chain-drive, belt-drive, and smart systems.
If your remote isn’t responding, the door reverses unexpectedly, or the motor runs but the door won’t move, we can pinpoint and resolve the issue. We also handle sensor realignment and replacement, ensuring your system’s safety features work as intended.
Our goal is to restore convenience and reliability while extending the life of your opener system.
Panel and Track Repairs
Safe, Precise Spring Replacement
Bent panels or damaged tracks can compromise both the appearance and safety of your garage door. We offer panel and track repair services that restore the structure and function of your system without requiring a full replacement.
Whenever possible, we match new panels to your existing door to maintain a consistent look. If the damage is extensive, we provide honest guidance on whether repair or replacement is the better long-term investment.
