Tristan Colgate 36 Alexandra Road Winbledon SW19 7JZ Mob. 07775783961 To whom it may concern, I was introduced to Mariusz and Marson Engineering through my builder. Mario plumbed in a new megaflow boiler into our Victorian house that supplied three bathrooms and 14 radiators around the 3 storey house. He did so speedily and effectively, dealing with the ancient pipework and advising me of potential problem areas. The new system works perfectly and I would certainly use Mariusz again – he is that rare breed of knowledgeable, friendly, and dependable plumber.
