    Super friendly and helpful team, and very reasonably priced stock. We picked up some greenhouse glass following the storm - so glad to have this local business. We’ll be back for more glass/ mirror bits and pieces!

    Excellent service and a good price. I had some single pane glass break that needed replacement cutting, Graham was able to arrange a replacement pane the same day. Would highly recommend!

    Graham has just been to repair 6 panes on our old greenhouse and he was brilliant. He did his upmost to help pull the old greenhouse into shape including moving other panes back into place that had slipped, fixing the door that was flapping around and delivered excellent customer service and was very friendly. I would definitely recommend him.
