How do we do it?

We take out the timber sashes and take them off site to our workshop in Twickenham. At the workshop, the sashes are stripped back to wood, the joints are rebuilt, the glass is cleaned and re-sealed into the frames, rot repairs are carried out, then the sashes are primed, undercoated and 2 finish coats are applied using The Little Green Paint Company paint. On site we restore the sash boxes by stripping back to wood, rot repairs are carried out and new hardwood cills can be installed. The boxes are then painted to finish coat. Once the sashes and sash boxes have been restored then the sashes are re-installed incorporating a draught-proofing system and new waxed cotton sash cords. Finally new sash window furniture and locks are fitted This process takes approx one week. During this time the windows will be boarded up with security boards when we are not on site.
