The door feels heavy, or drops the last bit instead of settling
Why it happens
Springs lose tension with use, and rust speeds that up near the beach. Most torsion springs are rated to around 10,000 open-and-close cycles, and a door used several times a day gets there faster.
Why it matters
A door that feels heavy or slams down has a spring near the end. It's worth replacing before it snaps, and the door shouldn't be used while it needs adjusting.
Response
Thom checks and adjusts the spring balance on every service.
