Garage Door Repair — Common Problems We Fix
From broken springs to motor failures, we handle all garage door repairs for homes and businesses.
🔩 Broken Spring Repair
Torsion springs typically last 10,000-25,000 cycles. When they break, the door becomes very heavy or won’t open at all. We replace springs with high-cycle units and rebalance the door.
⚡ Motor/Operator Repair
Garage door motor not working? We diagnose and repair all brands including SOMMER, Chamberlain, LiftMaster, and Chinese motors. Motor replacement available if repair isn’t cost-effective.
🚪 Panel Replacement
Vehicle impact or weather damage? We can replace individual damaged panels without replacing the entire door. Color matching and custom panels available.
📡 Remote & Keypad Issues
Remote not working? Lost remotes? We program new remotes, replace batteries, troubleshoot receivers, and install wireless keypads for convenient access.
🔊 Noisy Operation
Grinding, squeaking, or rattling sounds? Usually caused by worn rollers, loose hardware, or lack of lubrication. We diagnose the source and restore quiet operation.
🛡️ Safety Sensor Repair
Door reversing unexpectedly or won’t close? Photo-eye sensors may be misaligned, dirty, or faulty. We realign, clean, or replace sensors to restore safe operation.
Preventive Maintenance Program
Scheduled maintenance prevents breakdowns and extends door lifespan. Recommended for factories with high-traffic doors.
