Having been let down very badly by the previous builder, we really needed help. We were most fortunate that we found Dave Minton; he was personable and easy to deal with from the outset, did what he promised and achieved a high standard of meticulous workmanship throughout. Timekeeping was spot on, the workforce was polite, cheerful and efficient at all times. Project management was fine, it was clear what was going to be done on site each day. We are delighted with the end result. Highly recommended.

Alan is very friendly, helpful and polite, he discussed the requirements in detail and any unforeseen problems were explained and dealt with. The work area was left clean and tidy each day.

We were delighted with the work on the chimney, he is a fantastic render and plasterer. cliff is now renovating our bathroom, plus our neighbours are also putting him to work. An added bonus is he is a good communicator so he was able to work with our two very different personalities with different ideas, Cliff took it all in his stride.

Terrible experience all around. First bathroom was finished 2 weeks behind schedule and left with a leaking shower and lots of snags (messy grouting, misaligned taps, uneven tiles, etc). Second bathroom was ripped out and left unfinished because he had an accident (different stories) and no backup crew. Then, came back to fix snags from first bathroom but left loads undone/incomplete and, when confronted, he accused me of wanting to hold on to £200 for nearly a £20,000 bathroom project.
