This dormer window was a victim of poor material selection in the form of untreated softwood. Unfortunately, it wasn’t worth repairing, so we made a new pressure treated softwood window and fitted it with the latest argon filled double glazed units.
Pressure treated softwood has superior rot resistance to hardwood and once decorated, it will far outlast a uPVC window.
To ensure the window was weather-tight against the tiles, we fitted rebated linings which seal the edges.
