This sash window had been subject to a previous repair, where the lower section of the sill had been removed and a new section of sill simply screwed into the remaining piece of sill.
The screws had rusted over the course of just a few years and drawn moisture deep into the timber of the sill, rotting both the repair and the remaining piece of original sill.
We removed the entire sill, took careful measurements of the window and made an entire new sill in Accoya wood to fit perfectly. By joining it into the original window, we restore its structure whilst the choice of acetylated pine gives one of the most vulnerable areas of the window the greatest rot resistance.
Some new beading and a new solid brass catch complete the job, ready for final decoration.
