Ben is a highly competent and reliable builder. He completed our kitchen/garage conversion and bathroom work efficiently and to a great standard. Ours was a complex job with many different components all of which Ben tackled with no complaints, routinely offering practical solutions to any issues that arose which enabled us to retain our look and feel while keeping to budget. With us for nearly 7 weeks, Ben was very friendly at all times and we felt totally happy leaving him alone with keys to the house.

We had them in to install insulation in our upstairs floor, replace the sub floor, replace some lights, install a loft hatch, and board out our loft. On top of this they discovered a problem in our roof that they fixed. We were incredibly impressed by all of the staff that attended on site. They were friendly, polite at all times, and worked really hard, to a high standard. I couldn't recommend James and his team more, and we've already started talking to them about a further project.

SOUTHAM PLASTERING

Reviewed by Mel on 27/5/2018

BE WARNED! OK plasterer, APPALLING BUILDER. Put rubber roof on when wet, so now roof is blistering/bubbling. Tried to use piece of aluminum and wood to hold up roof--told by builder inspector he needed lintel. Lied to us, ignored inspector & tried to carry on using aluminum. Tired to get us to pay for insulation included in the quote. Got angry when we asked him not to smoke in our house. Three weeks after said work would be done (and with no changes to original job), walked off job without work completed.

I would recommend Andy. He spent time evaluating the job required with a view to looking at less costly but effective options. Most of the time I was out at work, he called everyday when he was leaving to update me on progress. He communicated clearly and so there was no confusion with what the job involved and the final cost. He was also very nice to my dog. Thanks Andy.
