Frequently Asked Questions
As one of the best garage door companies Portsmouth, NH has to offer, our team knows that garage door issues can happen unexpectedly and impact your safety and daily routine. Explore our frequently asked questions below to learn more about our repair offerings.
How do I know if my garage door springs need replacement?
Garage door springs are essential for smooth and safe operation, but they wear out over time due to repeated use. Signs that your springs may need replacement include difficulty opening or closing the door, uneven movement, visible gaps or breaks in the springs, loud banging or snapping noises, and the door failing to stay open. Attempting to repair springs yourself can be extremely dangerous because they are under high tension. Our professional technicians at D&D Garage Door Co can safely inspect, repair, or replace torsion or extension springs, ensuring your garage door operates reliably. Timely spring replacement prevents further damage to the door system and ensures the safety of your home and family.
How can I maintain my garage door to prevent costly repairs?
Regular maintenance is key to extending the lifespan of your garage door and preventing unexpected repair costs. Simple steps include lubricating rollers, hinges, and springs, cleaning the tracks to remove debris, inspecting cables and hardware for signs of wear, and testing the safety sensors and opener functions periodically. Scheduling professional maintenance can help identify potential issues early, ensure proper alignment, and verify that all components operate safely and efficiently. Regular upkeep not only reduces the likelihood of emergency repairs but also enhances performance, energy efficiency, and the overall appearance of your garage door.

Broken garage door springs can prevent your door from opening or closing properly and pose serious safety risks. As one of the leading garage door companies in Portsmouth, NH, our technicians at D&D Garage Door Co can safely remove the damaged spring and install a high-quality replacement, calibrated for your door's weight and size. We carry various spring types to fit most residential and commercial doors, ensuring reliable performance. Prompt repair restores functionality and prevents further damage to your garage door system.
How do I know if my garage door cables need repair?
Garage door cables are critical for balanced, safe operation. Signs of wear include fraying, broken strands, uneven door movement, or the door becoming stuck. Our technicians inspect cables during routine maintenance or emergency service. We replace damaged cables with durable, properly rated options, ensuring your door remains secure and operates smoothly. Timely cable repair prevents further system damage and reduces safety risks.
When should I schedule garage door opener repair?
If your garage door opener makes unusual noises, opens or closes inconsistently, responds slowly to remotes, or fails to operate, it may require repair. Our technicians are skilled in repairing all types of openers, including LiftMaster models. We diagnose the problem, replace worn components, and calibrate the opener for smooth, quiet, and reliable operation, ensuring your door functions safely and efficiently.
