EXCELLENT Based on 29 reviews Megan FitzsimmonsTrustindex verifies that the original source of the review is Google. Great service 10/10 Tracey WoodsTrustindex verifies that the original source of the review is Google. I approached Tristan at Diamond Property Maintenance having seen a Tik Tok video demonstrating their impressive approach to cleaning gutters! A conversation with Tristan led me to decide to engage other services as well, keen as I was to do what I can to protect the house against damp. Tristan explained the benefits of cleaning my roof of all mud/moss and talked about how the protective coating applied would protect my roof for the long-term. There was no hard-sell, just a knowledgeable approach that put me at my ease. The team were great, and I am delighted that we have had this work done, one to protect our home, but I am even more delighted at the significant improvement to the house’s appearance. The colour of the original roof tile is just lovely, and they also cleaned our patio and driveway, again using their protective coating to prevent the unsightly green/brown staining from re-emerging. I would definitely recommend Tristan and his team. Very impressed by the service received. Doreen McGuinnessTrustindex verifies that the original source of the review is Google. Brilliant work!!
