Garage Door Spring Repair in Merrimack, NH

A loud bang from the garage, followed by a door that suddenly feels too heavy to lift, almost always means one thing: a broken garage door spring. Freedom Garage Door Repair offers same day garage door spring repair in Merrimack, NH and the surrounding Hillsborough County area, with common spring sizes carried on our trucks so most repairs are finished on the first visit.

Springs do the heavy lifting on every garage door – the opener only guides the door up and down. When a spring fails, the door becomes unbalanced and unsafe to use, so it is worth getting it fixed properly and quickly. Call (603) 375-3366 any time, day or night.

Signs Your Garage Door Spring Is Broken

• You heard a loud bang or snap from the garage.
• There is a visible gap in the coil of the spring above the door.
• The door is very heavy to lift by hand, or slams down when released.
• The opener strains, lifts the door a few inches and stops, or reverses.
• The door rises unevenly, or a cable has come loose.

Torsion and Extension Springs

Most garage doors in Merrimack use one of two spring systems. Torsion springs sit on a metal shaft above the door opening and wind up as the door closes. Extension springs run along the horizontal tracks on each side and stretch as the door closes. Both store a large amount of energy and must be matched to the weight and size of your door. We repair and replace both types, and we can convert an older extension spring setup to torsion springs when that makes sense.

Why Spring Repair Is Not a DIY Job

Garage door springs are under extreme tension. Releasing or winding them without the right tools and training can cause serious injuries, and an incorrectly sized spring leaves the door unbalanced and wears out the opener. We use proper winding bars and spring-sizing methods, so the job is done safely and the door is balanced correctly.

What Happens on a Spring Repair Visit

• We inspect the door, springs, cables, drums and rollers to confirm the cause.
• We measure the old spring and the door to match the replacement correctly.
• We replace the broken spring (and recommend replacing a worn matching spring).
• We balance the door so it stays in place when stopped halfway up.
• We lubricate moving parts and test the opener's auto-reverse safety feature.
