Thank you to LightWeight Tiles in Lydney my dream is heading to reality. After buying a garden room with my share of inheritance money after losing my mother. I was so upset at the quality I was distraught. Lightweight tiles came to the rescue. Not only did the team in the office – Susan and Carol help us with the estimate and order, but we were shown how the tiles are produced and got to meet the whole team, who were really informative and helpful.
As a bonus Charlie and Josh even spent a couple of evenings after work putting the tiles on for me. The glazing is almost complete, and it is so lovely and warm that I can’t wait to spend more of my time relaxing inside, remembering my Mum in a lovely environment. Thank you so much
