What can I say about Christian and his father - Nicolas. They did an absolutely amazing job in our home. From the moment I spoke to him about the work to be done I knew I would hire him. He was professional from start to finish and did a stellar job on splitting a room into two and creating a hallway. Very pleased with every part of the work done and will most certainly use him again. Highly recommend.

Kitchen Fitting- 14 Oct 2026
I contacted this tradesperson to carry out several small jobs at my property for flooring and kitchen worktop. He visited in person, quoted me a price, and I agreed to proceed. He told me he could complete the work in a day. so I went ahead and purchased all the materials myself, which involved a considerable expense. However, he subsequently passed the job to another tradesperson, who visited and increased the quoted price by four times. I later contacted him for only the kitchen work already committed He agreed for weekend Instead of demonstrating a clear commitment to carrying out the work himself, he repeatedly focused on the price and continued delegating the jobs to other workers. On another occasion, he quoted approximately £500 for a single task that was expected to take a single day, but he failed to show up. I found the tradesperson unreliable and unprofessional, with poor communication, inconsistent pricing, and a lack of commitment to the agreed work

What to ask a Sevenoaks extension builder before hiring?

Before hiring an extension builder in Sevenoaks or extension building company in Sevenoaks, 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 Sevenoaks?

An extension builder in Sevenoaks 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 Sevenoaks 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 Sevenoaks?

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 Sevenoaks 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 Sevenoaks 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.
