    Caroline - Image 1 "Have used J Shirley for several jobs - fitting Velux windows with shutters, extending a porch roof, installing some drainage. Very happy with all aspects of the work and would not hesitate to recommend (and have already done so)."

    David Lloyd - Image 1 "We were looking for a reliable contractor to construct a new ensuite and dormer in a loft space adjacent to a bedroom. We went out to tender and appointed Jamie Shirley who impressed us with his quotation and previous work he had done. It proved to be a good choice as he carried out the work completely to our satisfaction so can be highly recommended"
