  • Conservatory rebuild

    10Verified Review

    Excellent workmanship, would definitely recommend. From start to finish Eric, Allan Leon and Arryon made the whole conservatory rebuild worthwhile. After a few years of procrastinating that a Upvc structure would not look right with our 150 year old house, It has surpassed my expectations. It is now a lovely, useable room with all the benefits of a modern structure.

  • Modern Extension to the Kitchen plus new landscaped garden

    10Verified Review

    Conservatech have just built us a modern, insulated extension from the kitchen to the garden. From our first meeting with Allan to the last day I cannot fault this company. The whole team are polite, respectful, professional and a pleasure to have met them all. They all worked extremely hard and cleaned up every day before leaving. We would like to thank Allan, Eric, Jack, Keenan, Leon, Ayrron, Phil, Craig and Steve for everything they have done for us. We wish you all much deserved continued success. Ellie and Nev Hinchliffe
