What should Welwyn Garden City homeowners know about replacement sectional doors?
What happens to the old door?
We remove it, including its springs and frame, and take it away for disposal or recycling where quoted.
Does the sectional door go behind or in the opening?
Fitting behind the opening usually gives the best clear width and seals well against the inside face of the wall. In some garages fitting within the opening is necessary; the survey decides.

Will the local district or borough council need to approve my new garage door?
Usually not.
