What should I know about double and wide roller garage doors in Welwyn Garden City?

Think about electric operation for any opening over 4 m, since the wide doubles in our price list are all electric.
Ask whether pier removal needs building regulations approval before planning to turn two openings into one.
Check whether the floor slopes or dips across the opening, as a wide bottom rail needs to sit evenly when closed.
Measure the width of your opening at the top, middle and bottom, and use the narrowest figure for your guide price.

Rules that apply in Welwyn Garden City

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.

Double and wide roller garage doors in Welwyn Garden City: questions

Is the survey in Welwyn Garden City 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.

Do you cover Welwyn Garden City?

Yes. Welwyn Garden City is part of the area we cover in Hertfordshire, including AL8, AL7 and AL6. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Do you charge more for Welwyn Garden City than other towns in Hertfordshire?

No. Guide prices are the same for Welwyn Garden City as for anywhere else we cover in Hertfordshire. 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.

Can you remove my old garage door in Welwyn Garden City?

Yes. Every door price includes removing and disposing of an old roller or up-and-over door at your Welwyn Garden City 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 if my garage opening is wider than 5.5 m?

We price it on survey. Openings over 5.5 m fall outside our standard price bands, because the door, the lintel and the fixing points need to be checked and specified individually. You can still use the online tool to tell us about the opening, and we'll arrange a free survey and give you a 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.
