After a thorough evaluation of three competitive quotations for a conservatory, this firm was found to have both a superior specification and a price considerably lower than the others. The technically experienced Director who dealt with us throughout attended to every detail and the finished job was completed almost on schedule with no requirement for a return to fix problems. It was a pleasure to deal with the company.
