Where garage door installs go wrong
Garage door problems show up as noise, imbalance, opener failure, and in the worst cases, safety incidents. Most trace back to spring selection and calibration. The rest trace back to opener compatibility, inadequate weatherstripping, and skipping the balance test after installation.
The 10 pitfalls
Installing extension springs when torsion springs are the better choice
Extension springs fail at lower cycle counts, are more dangerous when they break (they can fly if not properly contained), and do not provide the same smooth operation as torsion springs.
Not testing balance after installation
An unbalanced door strains the opener motor, wears out faster, and can fall unexpectedly when the opener is disengaged.
Low R-value on an attached garage door
The garage door is one of the largest uninsulated surfaces in an attached garage.
Incompatible opener for door weight
Openers are rated by door weight.
Reusing old tracks without inspection
Old tracks that are bent, misaligned, or wrong gauge for the new door cause binding, excessive wear, and noise.
Photoelectric sensors at wrong height
Safety sensors (photoelectric eyes) must be within 4-6 inches of the floor to detect a person or pet in the door path.
Inadequate bottom seal
The bottom astragal seal must contact the floor across the full width of the door.
Standard-cycle springs for high-use garages
Families who use the garage door as the primary home entrance cycle the door 6-8 times per day or more.
Not testing the auto-reverse function after installation
Auto-reverse should be tested with a 2x4 laid flat on the floor: close the door on it and confirm it reverses immediately on contact.
Paying in full before the door is installed
Once the door is installed, your leverage for resolving balance issues, weatherstripping gaps, and cosmetic problems is limited.
The bottom line
Balance test after installation. Confirm spring type and cycle rating. Verify safety sensor height and auto-reverse function. For attached garages, specify a minimum R-value. Those four things determine whether your garage door installation is safe and durable.
