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

Compare steel with insulated aluminium if a warmer garage is a priority, as it's the foam-filled lath that reduces heat loss.
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.

How does it work in Portslade?

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 Portslade

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.

Steel roller garage doors in Portslade: questions

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

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 Portslade. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.

How much do steel roller garage doors cost in Portslade?

Our guide price for steel roller garage doors is from £1,345 inc VAT. The figure for your garage depends on the opening size, the door specification and any extras, and is confirmed in a written quote after a free survey. The guide prices are the same in Portslade as elsewhere we cover.

Is the survey in Portslade 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 charge more for Portslade than other towns in East Sussex?

No. Guide prices are the same for Portslade as for anywhere else we cover in East Sussex. 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.

How do I open a steel roller door in a power cut?

Use the manual override, normally an internal crank or winding handle that turns the barrel by hand. Keep it somewhere you can find quickly. A steel curtain is heavy, so take your time and wind steadily. If you'd rather not crank it, battery backup keeps the door running for a limited number of cycles while the power is off.

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.
