These are representative jobs done by the Brock Garage Doors Hempstead crew. We don’t publish customer names or addresses, but the scenarios are real ones we see in Hempstead, Uniondale, West Hempstead, and Garden City all the time.

Torsion Spring Replacement on a Clopay Steel Door

BeforeAfter

The problem: a single torsion spring snapped while the door was mid-lift, leaving a 160-pound door hanging uneven and too heavy for the opener to move safely. We replaced both springs, not just the broken one. Springs wear out in pairs, and a mismatched pair will tear through the new one within a year. The result: the door balanced by hand and lifted without strain. Spring replacement on a standard Hempstead two-car door like this typically runs $280 – $430 depending on spring size and cycle rating, and the parts and labor are covered in writing for 365 days.

One note on safety here: torsion springs are under enough tension to cause serious injury if they let go while someone is working on them. We never recommend a homeowner touch these. Our techs use the right winding tools and follow a set removal and install procedure every time.

Snapped Lift Cable on a Wayne Dalton Door

BeforeAfter

The problem: one lift cable snapped at the bottom bracket, so the door jammed hard against the track and sat cocked at an angle. The homeowner couldn’t get their car out. We replaced both cables, inspected the drum and roller condition, and reset the tension. The door came down straight and quiet. Most cable repairs on a single door run $150 – $275 in this area, depending on cable type and whether the drums need replacement too. If you’re hearing a grinding noise or the door looks uneven in the track, that’s usually a cable or drum issue and it’s worth a call before the door binds completely.

Garage Door Opener Motor and Gear Replacement

BeforeAfter

The problem: a LiftMaster opener had been grinding for weeks and finally quit. The plastic drive gear had stripped and the motor was overheating. We replaced the gear assembly and the motor module rather than selling a full new opener, which saved the owner about $200 versus a complete replacement. The opener now runs with full force and the safety sensors were re-checked as part of the job. Opener repairs like this in Hempstead usually land between $180 – $340, while a full opener replacement with a new unit runs $450 – $750 installed. We carry common LiftMaster, Chamberlain, Genie, and Craftsman parts on the truck so most opener repairs are done in one visit.

Off-Track Door with Bent Roller Hinges

The problem: a teenager backed into the door before it finished opening, pulling the bottom panel off the track and bending two hinges. The door wouldn’t close and the panel was scuffed but usable. We reset the track, replaced the hinges, swapped in a set of nylon rollers, and adjusted the spring tension. The door now runs quieter than it did before the accident. Off-track repairs with parts usually cost $150 – $300, and we confirm the written number before touching the door. The owner kept the old steel rollers as a reminder to stop backing in before the door’s fully up.

Cable Drum Replacement on an Amarr Door

The problem: an Amarr single-car door kept eating lift cables. The cable drum grooves were worn smooth, so the cable slipped and bunched instead of winding evenly. We replaced both drums, both cables, and re-lubed the bearing plates. The repair took about 90 minutes and the door has held tension through a full Long Island winter since. Drum and cable combos on a single door run $200 – $350 around Hempstead, and it’s the kind of failure we see a lot in neighborhoods near Hempstead Turnpike where doors get years of salt air and humidity.

Roller and Hinge Refresh on a Noisy Genie Door

The problem: a Genie steel door was so loud the homeowner could hear it from three rooms away. The rollers were original steel with flat spots, and the hinges had never been lubricated. We replaced the rollers with nylon ones, lubricated every hinge point, and torqued the track bolts. The door now opens with roughly the sound of a refrigerator drawer. Roller and hinge refreshes run $120 – $220 and take about an hour. If your door sounds like a box of tools falling down stairs every time it moves, this is the fix that solves most of it.
