A door that's slowly got heavy to lift by hand
Why it happens
Springs lose tension slowly as they wear. Most torsion springs are rated for around 10,000 open-and-close cycles, which is roughly 7 to 10 years in an average home.
Why it matters
On an older door the change is so slow that people blame the opener. The opener then works harder to make up for tired springs, and it wears out sooner too.
Response
Spring tension and balance is the first check in every service. Tell Thom the door type when you ring, so he brings the right spring.
