The door's gone heavy, lifts crooked or went bang
Why it happens
These are the classic signs of a broken or worn spring. You might also spot a gap in one of the springs above the door.
Why it matters
A door with a broken spring is too heavy to lift safely. Springs hold a lot of force and can cause serious injury if they let go.
Response
Leave the door down and call. Tell Thom the door type when you ring, so he brings the right spring. On a door with two springs, it's usually worth replacing both at once, since they wear at the same rate.
