Broken spring
A broken spring leaves the full door weight unsupported.
Springs and balance
Garage Door Feels Heavy to Lift
A balanced garage door should feel fairly light when lifted by hand. If it suddenly feels very heavy, the springs are probably not doing their job. That makes the door unsafe to lift and hard on the opener.
Short answer
A heavy door usually means a broken or weakened spring. Look for a gap in the spring above the door or a stretched extension spring. Do not keep lifting a heavy door by hand. Book a technician to check the springs and balance.
Likely causes
Springs losing tension
Springs weaken with age and cycles.
Added weight
Insulation, new panels or decorations add weight. See balance adjustment.
Binding hardware
Rusted rollers or tight tracks add resistance.
Most residential doors weigh well over a hundred pounds, and larger double doors weigh much more. The springs are what make that weight feel manageable. When a door suddenly feels heavy, the springs are no longer carrying their share, and lifting it repeatedly puts that load on your back and the opener's gears instead.
Safe checks you can make
- Look for a gap in the spring
- Look at cables for slack
- Think about recent changes to the door
Stop and call a technician if
- The door is extremely heavy
- A spring or cable looks broken
- The door will not stay up
What a technician may inspect
- Springs and cables
- Door balance
- Rollers and tracks
- Opener strain
Describe what the door is doing when you call. A provider may ask follow-up questions, but a reliable price normally needs an on-site look rather than a phone-only quote.
