What should I know about insulated roller garage doors in St Austell?

Check whether the garage has other weak spots, such as a single-glazed window or a gappy side door, that will still let heat out after the new door goes in.
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.
Check whether the floor dips or rises across the opening, because an uneven floor can leave a gap under the bottom rail that lets draughts in.
If the garage is integral, consider how much cold air and noise currently reaches the rooms that share a wall or ceiling with it.

Insulated roller garage doors in St Austell: questions

Can I message you a photo of my garage in St Austell?

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

How much do insulated roller garage doors cost in St Austell?

Our guide price for insulated roller garage doors is from £1,495 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 St Austell as elsewhere we cover.

Can you remove my old garage door in St Austell?

Yes. Every door price includes removing and disposing of an old roller or up-and-over door at your St Austell 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.

Can I get a price for St Austell 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.

Is an insulated door more secure than a single-skin one?

Not automatically. Insulation and burglary resistance are separate qualities. How well a door resists attack depends on how that specific manufacturer's model has been tested, for example to LPS 1175 or STS 202. If security is a priority, look at our security-rated doors, which are also insulated, and we'll show you the certificate for the exact model.

Can insulation be added to my existing roller door?

Not in a practical way. The foam sits between the two aluminium skins of each lath when it's made, so a single-skin curtain can't simply be filled or lined. Getting insulated laths means a new curtain, and because the box and barrel need to suit the larger roll, that normally means a new door, which we can quote as a replacement.
