Great job. Back garden looked like it did the day we finished it last year, brand new stone again .can't believe how well it looks.will definitely get it done again when needed.

Excellent job on the balcony in @ SkerriesGC. I would have no hesitation in recommending him to anyone looking any external cleaning done.

Hi, I have a lovely natural slate roof which is slowly being crippled by moss, algae and fungus. Your websites are very informative as I sought to better understand how to restore my roof and render. Clearly, your product and the soft wash application seemed perfect. I called the office and Rosa could not have been more helpful. She mentioned that a local contractor in Skerries does a very good job using Algoclean. I called Matt Derham, he visited the same afternoon at the time he promised, provided me with a quote which I thought fair and arrived at 9.30 sharp. With good humour and a ton of knowledge he and his crew set about a thorough soft wash meticulously prepared and applied. Every slate and wall was treated with professional care and courtesy. Everything was explained, nothing was too much trouble and even my kayak got a wash for the algae on the amas. They left my home spotless tidying everything and moving pot planters back in place. And so I want you to know that I'm very impressed with the product and phenomenally grateful to Matt for doing a great job with good humour and grace. I have no doubt that the product will work and solve the problem. So please have no doubts about recommending Matt for any future jobs. His attention to detail, good humor and focus on doing a great job is simply superb.
