Graeme Chisholm, Camberwell
London Sash Windows and Doors renovated my back door which was in a very poor state but after days of pain staking restoration work it is now draft proof and pristine. An added bonus was the revealing of details chiseled into the main panel by the original Victorian craftsman which had been completely obscured by layer upon layer of paint. Their dedication to bringing back to life tired, old wood work and the meticulous lengths that they go to to achieve this is exceptional. I highly recommend them.
