An interesting experience.
Had a visit from the garage door man.
First question. "What are you trying to achieve?"
"We are finding it increasingly difficult to open our garage door and would like to consider an automatic door opener."
Door inspected - it's a large double garage up and over door.
Verdict. All in good order but the problem will be solved by fitting new springs - total cost inc. VAT. £406.
Two options for automation.
Use existing door with springs replaced and fit start/stop operator. Total £946.
Fit new automated roller door. £2903.
We are going to visit the company to look at the operator in action as well as the automated roller door. Although I'm happy to consider each option my wife seems keen on just replacing the springs to see how she copes before spending any more on automation.
