Bricklaying- 27 Aug 2021
Mitch and his team were efficient at building the retaining wall in my garden, working on a Saturday to get the job done. The work was completed to a very high standard. The wall had to be left slightly unfinished in order for other works to happen first, so Mitch promised to come back and finish off the wall at no additional cost later in the week. After some chasing, Mitch came back to finish the wall by himself the following Saturday. This was also completed to a high standard. We would highly recommend Mitch’s service for an efficient, high standard output.
