What should I know about steel roller garage doors in Welwyn Garden City?

Measure the width of your opening, because our steel price list covers singles up to 2.4 m and doubles of 3.0 to 4.0 m, and other widths are priced on survey.
Check the lintel above the opening for cracks or sagging, since a heavier steel curtain relies on sound fixings at the top.
Look at the brick or blockwork on each side of the opening, as the guide rails for a steel door need solid reveals to fix to.
Decide where the override handle will be stored, because you'll need it to wind a steel curtain up during a power cut.

Rules that apply in Welwyn Garden City

Steel roller garage doors in Welwyn Garden City: questions

What do you check at a survey in AL8?

At a survey in AL8 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 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.

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.

Can I repaint a steel roller door later?

When you order a new steel door, you can choose a RAL colour or woodgrain finish as a priced extra, and colours outside the manufacturer's range are priced on survey. If you're thinking of repainting the door years later, check the manufacturer's care guidance first, as their warranty terms for the door are set out in writing in your quote.

Why are steel doors over 4 m wide priced on survey?

Our standard steel price list covers single openings up to 2.4 m and doubles of 3.0 to 4.0 m; other widths are priced on survey. A wider steel door needs the opening, lintel and fixing points checked individually before the right door can be specified, so we price it after the survey rather than from a table. For openings up to about 5.5 m, insulated aluminium doors have a set price band you can see online.
