Can anybody recommend a person to replace a double glazed window in a bedroom and a hopper window in a bathroom in our house. Also, my daughter and son-in-law need two windows replaced + a replacement roof on a conservatory. We only want somebody who is going to come and quote quickly, as so many companies/one-man-bands either don't turn up or otherwise take weeks to come back with quotes (obviously they don't want the work!). TIA
