Eastbourne, Lewes, Battle and the villages around them are full of houses with joinery worth keeping. Original doors, deep skirting, panelled reveals and turned balustrades are usually better made than anything that would replace them, and once they are gone the room loses a good deal of its character.
So the first thing we do on a period property is work out what can stay. Rot is usually local, and a spliced repair in matching timber, treated and painted, will outlast the rest of the frame. Where something has to be replaced we copy what is there, including the moulding profile and the glazing bar sizes.
On a listed building or in a conservation area, and there are several around here including Old Town, parts of Meads and much of Lewes and Battle, that matters for consent as well as for appearance. Like for like repair generally avoids an application where replacement would need one, and we are happy to talk to your conservation officer about what is proposed.
The coast adds one more consideration, which is exposure. Salt air and driven rain are hard on external timber and on fixings, so we use treated timber suited to the position, prime end grain before it goes in, and use stainless or suitably coated fixings where ordinary ones would stain and fail early.
