What should I know about insulated roller garage doors in Dorchester?

If the garage is integral, consider how much cold air and noise currently reaches the rooms that share a wall or ceiling with it.
Decide whether you want extras such as battery backup or a wireless keypad, so they can be included in the written quote rather than added later.
Wider openings usually suit 77 mm laths for rigidity, so expect the lath size to be confirmed once the width has been measured at survey.
Look for a socket or fused spur near the top of the opening, as every insulated door in our price list is electric.

Rules that apply in Dorchester

Powered door safety

Every powered door we fit is commissioned with force testing to BS EN 12453 and handed over with a Declaration of Conformity and UKCA or CE marking, as the Supply of Machinery (Safety) Regulations 2008 require.

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.

Insulated roller garage doors in Dorchester: questions

Do you charge more for Dorchester than other towns in Dorset?

No. Guide prices are the same for Dorchester as for anywhere else we cover in Dorset. 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.

Do you cover Dorchester?

Yes. Dorchester is part of the area we cover in Dorset, including DT1 and DT2. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Is the survey in Dorchester 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.

What do you check at a survey in DT1?

At a survey in DT1 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.

Are insulated roller doors available in different colours?

Yes. Insulated doors come in the manufacturer's standard range finishes, and you can choose a RAL colour or a woodgrain effect as a priced extra. Colours outside the manufacturer's range are priced on survey. If you're matching windows or a front door, have the RAL code to hand when you ask for a guide price.

Is an insulated door worth it for a detached garage?

It depends on how you use the garage. If it's only for parking or storing tools, single-skin laths may be enough. If you work out there, store anything that dislikes the cold, or want it quieter, insulated laths are worth the extra cost. Remember the walls, roof and floor also let heat out, so the door is only part of the picture.
