Martin did a great job fixing my leak last winter. It was done quickly and professionally. The only minor downside was when he re-plastered the wall (which is already huge that he did that!) some of the areas were thinner than others so you can see a corner of what looks to be netting - it was easy to cover up before repainting. But again, in terms of the whole project it's very minor thing. I'm already talking to him about a new project in my new place!
