I would highly recommend Michele! Could not have asked for anyone better! Michele did our garage conversion and a few extra jobs. He went above and beyond for us. Nothing was too much trouble. Top quality workmanship and a great guy too

Latest homeowner review

Reviewed by Michael on 17/10/2017

It was a relief to have a builder who doesn't take on other jobs at the same time. Mark and Gaz gave a reasonable timeframe and price and stuck to it. We had recently bought the property and ended up asking for considerably more work to be done than was first advertised. This is largely testament to the fact that we had built a trusting relationship with Mark and had peace of mind that the job would get done well and for the price quoted. Yes his banter was terrible at times but you can't have it all!

Came very quickly and completed the job (like-for-like electric shower replacement) satisfactorily, my only gripe is the price/cost. Said it would be about £250 - £350 at the start, on completion of the job the price had gone up to £480 and he wanted it in cash. Not much I could do when the job's finished and the guy's standing in the house wanting to be paid. On reflection I feel I have been overcharged and should have waited for the other responses to come in but needed it doing.
