Did an excellent job rebuilding our wall, including going to extra trouble to blend in with older brickwork. Left the site spotless. Remy the bricklayer was very considerate and went out of his way to minimise disruption during 4 days he was here.

Jun 2017 This review is only my personal experience of one set of work with Colwins so I have no idea what they may be like with other work. To date our experience has been absolutely shocking. Colwins were contracted via our insurers to do some work on our house following some subsidence. Part of the work included the filling of a crack in the front wall of our house. Most of the work was done but the crack wasn't repaired. This was over 4 YEARS ago and we have been chasing them ever since. Every time my wife phones they take note, promise to have a look into it and find someone to come around
