It was perhaps a small "bitty" job with a few complications (my fault) along the way but it was completed in time with good communication and expertise. It was done exactly as I requested at a good price so I have no hesitation in recommending.

This family have been marvelous, getting a very urgent collection sorted out for me mega quickly, so that l would not lose my property permanently (which was likely to happen imminently), and which would have caused me great distress. Now l can relax and sort things out with them once the worst of the pressure is off. Many thanks, boys, for being so kind. You will be first in consideration when l need someone with any of the large range of abilities that are on your list. Many thanks.

Shortly after finishing our renovation the floor began to lift, after a 2-year battle and almost court they admitted it was a fitting fault. Not ideal for a 12k job. Now our sink has fallen in, turns out he has used the world's smallest bit of wood and some sealant to fix it to the underside of our granite worktops rather than correctly fitting it using the fixings on the actual sink. Add to this, gaps between drawers and misaligned cupboards and you get the idea.

George responded quickly to my request, gave a very reasonable quote, did a really quite tricky and complicated job above a conservatory, to fix cracks in the pebbledash of an external wall, and seal all around the windows. A fortnight later he re-plastered internally. George gives the impression of being somewhat chaotic! But he is extremely experienced, knows what he is doing, and actually did a very good job. The timings and quote agreed to were respected, he was polite and cordial, and communicated well
