Extensions- 20 Mar 2020
Fantastic job constructing a side extension to create a new front door and hallway, and blocking up the existing door. Theo worked efficiently, and worked with us through a few 'design changes' along the way - without any complaint. Many thanks Theo - we're absolutely delighted with your work.
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

Extensions- 1 Jun 2022
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. Elliot and the team were professional and a pleasure to work with and we would highly recommend them.

We highly recommend James. He completed the stair refurbishment in a day and was very efficient, polite, worked with professionalism and respect to my home.

We were very impressed with James standard of work and have since hired him again to carry out an understair cupboard revamp which was carried out to the same very high standard. We will definitely use James again the future and recommend his to all.

What to ask a Marlow extension builder before hiring?

Before hiring an extension builder in Marlow or extension building company in Marlow, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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?

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 Marlow 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.
