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

Measure the headroom above the opening carefully, because insulated laths make a bigger roll than single-skin and need a deeper box.
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.
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.
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 Harwich

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.

Electrics

An electric door needs a power supply near the roller box. Electrical work must meet BS 7671, and in England some domestic electrical work is notifiable under Part P, so it is done by a registered competent person or signed off by building control.

Insulated roller garage doors in Harwich: questions

Do you cover Harwich?

Yes. Harwich is part of the area we cover in Essex, including CO12 and IP11. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

How much do insulated roller garage doors cost in Harwich?

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 Harwich as elsewhere we cover.

How long does it take to fit a roller garage door in Harwich?

Most single domestic roller doors are fitted in a day once the door has been made, including removing the old door. Wider doors, conversions that need building work and jobs where power has to be run can take longer; the quote says what to expect.

Can I get a price for Harwich 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 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.

Will an insulated door fit the same opening as my old single-skin door?

Usually, yes, but insulated laths are thicker, so the curtain makes a bigger roll in the box. If your old door had a small box, the new one may need more headroom, a box fitted under the lintel, or a face-fitted box. We check this at survey and explain the trade-offs before you choose.
