A 1930s detached house taken all the way round: floor, walls and roof, with structural steel going in along the way to open up the ground floor.
The suspended floors came up first, insulated with Gutex wood fibre over Pro Clima Solitex Plus, made airtight with Pro Clima DA membrane and Tescon Vana tape, then reclaimed boards went back down. Steico wood fibre board wrapped the outside, carried into every reveal, round the bays, under the eaves and down to an insulated plinth, finished in breathable silicone render. The roof was insulated with Gutex thermoflex and sarking board with a ventilated cavity above it, then re-tiled. Downpipes, soffits and the porch were all reset to the new wall line.
Adam and his team are the best kind of builders - hard working, paying attention to detail in every circumstance, listening to what you want and genuinely caring about the end result. Their tidying, snagging and completing was second to none. I can't speak too highly of them and we are absolutely thrilled with the end result. High quality work done by people who take pride in what they do.
