What should I know about steel roller garage doors in Windsor?

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.
Check the lintel above the opening for cracks or sagging, since a heavier steel curtain relies on sound fixings at the top.
Think about whether battery backup is worth adding, so the door keeps working for a limited number of cycles when the power is off.
Compare steel with insulated aluminium if a warmer garage is a priority, as it's the foam-filled lath that reduces heat loss.

How does it work in Windsor?

Once you accept, the fitting date is confirmed in writing, depending on installer availability. If a new spur is needed, it's shown in the quote and fitted by a qualified electrician.

Rules that apply in Windsor

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.

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.

Steel roller garage doors in Windsor: questions

What do you check at a survey in SL4?

At a survey in SL4 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.

Do you cover Windsor?

Yes. Windsor is part of the area we cover in Berkshire, including SL4, SL3 and SL1. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Can I get a price for Windsor 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.

Can I message you a photo of my garage in Windsor?

Yes. Photos of the opening, the inside of the garage above the door and any existing door help us give a more useful guide price for Windsor. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.

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.

Is a steel door the right choice for a row of lock-ups?

It can be, particularly where a stiffer curtain appeals for garages that are opened less often. Every steel door in our price list is electric, though, so each garage needs a power supply near its box. Where lock-ups have no power, manual aluminium doors may be more practical. We can survey and price a whole row together.
