Windows · Sash · Casement · Conservation
Sash, casement and conservation windows, matched to your building.
Most of our work begins with a single sash. New sets for listed cottages in Uckfield, full reglazes for Heathfield farmhouses, sympathetic reproductions for conservation areas across East and West Sussex and Kent, all drawn around your building's actual openings, not a catalogue.
Traditional sliding sash window with internal shutters
Every Forest Joinery window is built in our Bell Lane workshop from a survey we take ourselves. Profiles are matched to the originals you're replacing, ogee horns, lambs-tongue mouldings, slim sightlines, so the new windows read as part of the building, not bolted on.
Painted exterior windows are built in Accoya as standard: a modified softwood with a 50-year above-ground warranty, dimensional stability that ordinary timber can't touch, and a paint life that comfortably doubles a softwood casement. For hardwood frames we work in oak, sapele and European redwood, quarter-sawn where the grain matters.
We work with conservation officers daily. If your home is listed or in a conservation area, we can apply for listed building consent on your behalf, preparing the survey and section drawings the officer needs to approve the work, we've done it across most of the South East.

Common Questions
Can you make double-glazed timber sash windows?
Yes. Where the building's listing or conservation area allows it, we run slim double-glazed units in narrow conservation profiles, so you get the thermal benefit without the chunky sightlines of standard double glazing. Where double glazing isn't permitted, we build in traditional single glazing or slim heritage units to whatever the planners agree.
Can you match my existing windows?
Yes. Every set starts from a survey we take ourselves, off your actual openings rather than a catalogue. We match the original profiles, horns, mouldings and sightlines so the new windows read as part of the building, not bolted on.
Do you work on listed buildings and in conservation areas?
Daily. If your home is listed or in a conservation area, we prepare the drawings and profiles the conservation officer needs to sign the work off. We have done this across most of the South East.
What timber do you use?
Painted exterior windows are built in Accoya as standard, a modified timber with a long paint life and dimensional stability ordinary softwood can't match. For frames where the timber is meant to be seen we work in oak, sapele and European redwood.
Which areas do you cover?
We work from our Uckfield workshop across East and West Sussex and into Kent, including Heathfield, Crowborough, Lewes, Tunbridge Wells and the surrounding villages, roughly a 30-mile radius of the workshop.
