The current one we have is old-fashioned, it moves on a roller which is a faff - you open the side door, hook it into the rail and heave it around noisily. Now the wood is warped after decades and I don't suppose they sell those now with good reason.
Before a new gargage door is installed I guess I'd have to get someone to take up that rail along the base of the concrete floor.
A builder made the point that garages tend to be too narrow for cars because these old 1930s properties were in the day of Austin 7s and so on - narrow little runarounds that could take a smaller garage! No way to renovate them or widen them now if you're up against the neighbours.
He also pointed out that it's best to have a garage without moveable parts unless they beak. This makes sense - except, surely if you have a side-hinged door that makes it hard to open with the car in the drive? You'd have to park a way back. And move the car if you just needed to get into the garage, to check the meter (not done very often I know.) This didn't occur to me in our chat. Surely an 'up and over' garage is really the only option in most cases? Yet I do see garages with side-hinged doors along our street. Any thoughts?
