The line of the groove can be seen in the first few photos. Over the years, the filler had cracked and allowed rain into the timber, rotting the remaining sill.

The customer was very keen to stick with timber windows to maintain the character of this lovely period family home. Joinery Shop were asked to repair the sill and any rotten sashes while we were there.

We set about removing the sashes to assess the rot to the frame of the bay. We machined away rotten areas that we found all along the sill, mullions and posts. The bay had draft proofing grooves machined into it, so we matched those with the originals in the new Accoya sill.

We then machined the bottom of the posts back to good wood before joining in Accoya to rot-proof and make good the old grooves in the corners. Finally, we carried out A repairs to the front 4 sashes which had been patched with filler.

The use of properly jointed Accoya for the bottom rails, stiles and beading means the sashes are now even better than new with a 50 year rot resistance in the key areas that are most susceptible to the weather! A really satisfying repair which restores the curb appeal of this home for decades to come.
