John Burke Carpentry
Rating: 5 out of 5
Extension Builder in Marlow
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

Kitchen Fitting- 24 Oct 2025
Installation of new kitchen. Professional from start to finish. Klejdi made the whole experience of having a kitchen install a wonderful experience. No job seemed too difficult even when he ran into unforeseeable snags, he made me aware and just cracked on and did it at no extra cost. He has such an easy going personality which makes you feel comfortable having him around your home. The work that he had done was perfection. So pleased with the outcome that we asked if he happened to do tiling, to which he said he did. So had Klejdi to do this also. We had a difficult bit of wall to work with that he seemed to have no issues with. Again another job I’m very happy with. Thank you Klejdi and look forward to working with you again when I get the bathroom done.

What to ask a Marlow extension builder before hiring?

What qualifications and experience do you have as an extension builder in Marlow?

An extension builder in Marlow should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Marlow extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Marlow?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Marlow extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?
