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
