Good work but painfully slow and continually extended finish date. There were however, a couple of extenuating reasons.....but literally a couple. A few of small jobs still need to be completed but unfortunately, still waiting.....and waiting....and waiting for him to call back. If he does, I may alter the rating.

They are so much more than your average tradesmen; multi skilled, (great tiling and bathroom installation) tidy (put our team to shame), when we changed a main colour they were fab and just took it in their stride. We forget to order materials so they collected it for us. The quality of the work is second to none and has been admired by all. I have no doubt that it will be their work will sell our project.
