Kitchen Fitting- 20 Sep 2022
Efficient, accurate, hassle free!!! I appreciate the can-do and trouble-shooting attitude of the ENE Team. Although there were some unexpected hiccups in my job. I received clear explanation what was going on the spot, and how the team was going to help. A member helped me clean up my kitchen after the fixing job was done, in a responsible manner. If you would like to have some improvement / maintenance jobs at your home, and you don't exactly know how to do, I recommend you talk to ENE. You can receive their feedback and a quote within a very reasonable time frame. For my case, I got their quote in a morning. My job was done in the next working day before lunch.

Kieran removed my old front door and rebuild the loose bricks to the front porch. Then fitted a new door and sealed the door. This was a job I started but could not finish so even being a Sunday kieran still attended and was one of the most polite and friendly builders I have worked with. The overall quality of the work was excellent and way better than I expected.

We are absolutely thrilled with our extension. Elliot and the team completed all elements of the project, which included numerous steels to replace existing supporting walls and the re-fit of our existing kitchen +new kitchen fit out. The work is finished to a very high quality and far exceeded our expectations. Product selections such as doors, windows and tiles were proposed by Elliot and were exactly what we wanted.

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

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

An extension builder in Crowthorne 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 Crowthorne 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 Crowthorne?

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 Crowthorne extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Crowthorne extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
