There was an issue where the builders created dampness on the neighbour's internal wall. I called Adam and he came the next day and identified the problem immediately. He also came to my house and surveyed a problem that I was concerned about (a crack in an internal wall) that was nothing to do with the party wall agreement he was overseeing. He was there for an hour and did not charge me anything even though it was not paid for in the party wall award (it would have cost around £225 otherwise)-he said he was not far away on a job so it was ok. He gave me some additional advice about managing the builders. He really knows his stuff and is a really decent guy.
