What should I know about up-and-over to roller door conversion in County Londonderry?
- The old up-and-over panel, its springs or counterweights, tracks and arms are removed and taken away as part of the price.
- Clear width can improve slightly after a conversion, because there are no swing-out arms at the sides of the opening.
- We check the lintel and reveals at the survey, and price a new lintel or building out the reveals before you agree.
- Taking out the up-and-over tracks frees the garage ceiling for shelving, storage or better lighting.

Rules that apply in Northern Ireland
Structural work
Structural alterations, such as widening the opening or fitting a new lintel, need building control approval from your council under the Building Regulations (Northern Ireland) 2012 before work starts.
Planning
Replacing a garage door is not usually development that needs planning permission in Northern Ireland. Listed building consent applies to listed buildings, and conservation-area controls, planning conditions or covenants can restrict changes to how a garage looks, so check before ordering.
Questions about up-and-over to roller door conversion in County Londonderry

Which towns do you cover in County Londonderry?

Can you keep my existing up-and-over frame?
Sometimes. If the frame is sound, square and securely fixed, it can stay as a finish around the opening and the roller door is fitted to suit it. If it's rotten, damaged or out of square, we take it out and prepare the opening for the new door. The survey decides which applies to your garage.
Does a roller door need more headroom than an up-and-over?
A roller door needs headroom above the opening for its box, while an up-and-over needs space inside the garage for its tracks and for the panel when it's open. Domestic roller boxes are commonly around 205 to 300 mm or more, depending on door height and lath size. If there isn't room behind the lintel, other box positions are possible.
