What should I know about up-and-over to roller door conversion in Grantham?
- We check the lintel and reveals at the survey, and price a new lintel or building out the reveals before you agree.
- Electric conversions are commissioned with force testing to BS EN 12453 and a Declaration of Conformity at handover.
- Clear width can improve slightly after a conversion, because there are no swing-out arms at the sides of the opening.
- If headroom behind the lintel is short, the roller box can go under the lintel or be face-fixed on the wall.

Rules that apply in Grantham
Structural work
Widening the opening, removing a central pier or fitting a new lintel is structural work that needs Building Regulations approval from building control before it starts.
Planning
Replacing a garage door is not usually development that needs planning permission. Check first if your home is listed (listed building consent covers works that affect its character), sits in a conservation area with an Article 4 direction, or is on an estate where planning conditions or covenants control garage doors.
Up-and-over to roller door conversion in Grantham: questions
Do you charge more for Grantham than other towns in Lincolnshire?
No. Guide prices are the same for Grantham as for anywhere else we cover in Lincolnshire. The written quote reflects your opening and the door you choose, not your postcode, apart from islands and remote areas where any travel cost is shown in advance.
Is the survey in Grantham really free?
Yes. For a new door, a replacement or a conversion, the survey is free and there is no obligation to go ahead. We measure the opening, check the lintel, headroom, side room and power, and send a written quote afterwards.
Can I get a price for Grantham without anyone visiting?
Yes. The guide price tool takes four steps and gives a range for your opening and door type. It is a guide, not a quote: the written quote comes after the survey or once the visit price is agreed.
How long does it take to fit a roller garage door in Grantham?
Most single domestic roller doors are fitted in a day once the door has been made, including removing the old door. Wider doors, conversions that need building work and jobs where power has to be run can take longer; the quote says what to expect.
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.
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.
