We had 9 hardwood double glazed window units fitted by Dean Spencer and his work mate Danny. They were very polite, clean and very professional. 3 of the windows had to be removed from reveals with glazed tiles, and not one was damaged and you couldn't tell they had been there apart from the new look of the frame [excellent]. I would recommend them to anyone thinking of replacing any windows. A first class company with top grade workmen. Can't include copy of proof of purchase as I don't know how to do it on the computer, but you can all details from the EYG records.
