Broken Garage Door Spring
in Plano, TX
A broken garage door spring is the most common reason a door won't open or opens only a few inches. The torsion spring above your door does most of the lifting. In Plano, garage temperatures regularly hit 110 degrees in July and August, and that repeated heating and cooling wears the metal down faster than the spring's rated cycle count suggests. Leave it alone and you risk the door crashing down on a car, a bike, or a person.
Quick Answer
Garage door springs break because they wear out after a set number of cycles. Plano summers push attic and garage temperatures past 100 degrees, and that heat ages the metal faster. A technician replaces the broken spring and checks the cable and drum at the same time. Call (361) 470-4268 if your door stopped working overnight or you heard a loud bang.
Telltale Signs
Warning Signs to Watch For
- Door won't open at all, even with the opener running at full force
- You heard a loud bang from the garage, often at night
- The door opens 6 inches and then stops or reverses
- You can see a gap or separation in the coiled spring above the door
- The cable on one side has gone slack or is hanging loose
- The door feels extremely heavy when you try to lift it by hand
Root Causes
What Causes Broken Garage Door Spring?
Normal Cycle Wear
Most residential springs are rated for about 10,000 open-and-close cycles. A busy household in West Plano can hit that number in 7 to 10 years, and the spring simply breaks when the metal fatigues. There is no warning sign before it snaps.
The Fix
Torsion Spring Replacement
A technician removes the broken spring and installs a new one sized to the exact weight of your door. Upgrading to a higher-cycle spring, rated for 25,000 cycles, means you go much longer before replacing it again.
Heat and Temperature Cycling
Plano garages routinely reach 110 degrees in summer and drop below freezing a few nights each winter. Metal expands and contracts with every swing, and that repeated stress cracks the spring's surface coating and starts rust. Rust removes the protective layer and speeds up metal fatigue by years.
The Fix
Rust-Resistant Spring Installation
Replacing the spring with a galvanized or oil-tempered coil and applying a rust-inhibiting lubricant twice a year slows the corrosion cycle. The technician also checks the cable ends, which corrode at the same rate.
Improper Spring Size
Homes built in older parts of Plano near downtown sometimes had springs replaced by the previous owner with the wrong size. A spring that is too light for the door weight is under constant extra stress and breaks years ahead of schedule. You usually can't tell by looking at it.
The Fix
Correct Spring Sizing and Replacement
The technician weighs the door panel and matches the spring's torque rating to that exact weight. Installing the right size means the spring works at the load it was designed for.
