John Burke Carpentry
Rating: 5 out of 5
Extension Builder in Henley On Thames
Hi there, I hope you're well. My name is John and I ve been in the building trade for 20 years. I'm a qualified master carpenter, and there isn't much left I haven't done. Im a bathroom fitter as well, so plumbing, tiling, plastering, is all second nature to me. I ve done jobs in every trade, when I was an apprentice all those years ago, that's how my boss at the time worked. Knowledge is power as they say. I based in Bracknell, and I can travel up to an hour from there. So as far as Dorking to the east, and the same distance in the other directions. As I said, in my 20 years of working in the trade, I ve done nearly everything there is, I'm a friendly guy and happy to answer any questions. I won't be the cheapest, but I LL be one of the best. I look forward to hearing from you. John

Latest review:
We required two extensions - to the rear and above the garage at the side. We contacted Darek as he was recommended to us by a work colleague who lives in our area. We found Darek's prices to be competitive and he was very reasonable to work with, being flexible when our plans changed slightly. Having building work undertaken is never a pleasure, in our view However, we're pleased with the completed work and we found that working with Darek was as stress-free as it could have been. We would (and have) recommended him to friends.
