Questions Crowborough homeowners ask about new windows

Usually not, for a house. Replacement windows that look broadly similar are permitted development. The exceptions are flats, listed buildings, and houses under an Article 4 direction, and none of the town's older Article 4 directions cover house windows. The villages differ; see the planning guide.

A white chamfered uPVC casement at £815 to £1,200 per window, which suits the 1950s semis at Alderbrook and similar houses. A small 600 x 900 mm window in flush uPVC is £765 to £1,085.

A white uPVC sliding sash, the usual replacement on the Victorian terraces of Railway View and Western Road, costs £1,505 to £2,190 supplied and fitted, including VAT. A timber box sash costs £2,650 to £3,800.

Yes. Every price on this site is a range per window or door, supplied and fitted, including VAT, with the old frames removed and the opening made good inside and out.

Scaffold, if an upstairs window on a small job needs it, adds roughly £500. A bay that needs new support, a rotten sill or a dropped brick arch is priced after the survey.

Casements and tilt-and-turn windows that close onto compression gaskets, tested for an exposed site, with drainage that pine needles will not block. See windows on high ground.

Only if the house is listed or under an Article 4 direction, or you simply prefer it. A timber flush casement costs £2,000 to £3,800 against £1,100 to £1,950 for uPVC flush, and painted timber needs repainting every five to eight years, sooner on exposed elevations.

Bifold and sliding patio doors are not offered. Roof lanterns are not priced online because the cost depends on the structural work; send an enquiry if you need one.

Enquiries made on this site go to a FENSA-registered installation company, which surveys, quotes and fits in its own name. See how enquiries work.
