What should I know about double and wide roller garage doors in Caernarfon?

Ask whether pier removal needs building regulations approval before planning to turn two openings into one.
Measure the width of your opening at the top, middle and bottom, and use the narrowest figure for your guide price.
Check whether the floor slopes or dips across the opening, as a wide bottom rail needs to sit evenly when closed.
Allow extra headroom for a wide door, since larger laths make a bigger roll and need a deeper box.

Rules that apply in Caernarfon

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 in Wales before it starts.

Planning

Replacing a garage door is not usually development that needs planning permission in Wales. Check first if your home is listed (listed building consent covers works that affect its character), is in a conservation area with an Article 4 direction, or is on an estate where planning conditions or covenants control garage doors.

Double and wide roller garage doors in Caernarfon: questions

How long does it take to fit a roller garage door in Caernarfon?

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.

Do you cover Caernarfon?

Yes. Caernarfon is part of the area we cover in Gwynedd, including LL55. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Can you remove my old garage door in Caernarfon?

Yes. Every door price includes removing and disposing of an old roller or up-and-over door at your Caernarfon address, along with standard fixings and making good to the reveals. If the frame or lintel needs work, we price it at the survey before you agree.

What do you check at a survey in LL55?

At a survey in LL55 we measure the width and height of the opening, the headroom above it for the roller box, the side room for the guide rails and the floor level. We also look at the lintel and where power can come from for an electric door.

Can I convert a double up-and-over door to a roller door?

Yes. We remove the old door and its frame, or keep the frame if it's sound, then check the lintel and reveals. The box is fitted behind the lintel and the guides to the reveals. Any extra work, such as a new lintel or building out the reveals, is priced on survey and listed separately in your written quote.

Will a roller door give me more width than my double up-and-over door?

Possibly a little. An up-and-over door has a frame and swing-out arms at the sides, and a roller door doesn't, so converting can improve the clear width slightly. The guide rails still need some side room at each end. We measure the clear width you'd get at survey, so you know before ordering.
