Kitchen Fitting- 27 Apr 2019
Our experience with sonny was great. He was very professional including giving a detailed broken down quote and was always quick to communicate. Once the job started he was on time everyday, he tidied up after himself and he got the job done to a high standard. As the build happened he was flexible with changing things that we wanted to change and to help with solutions when things needed to be done differently. He was always very friendly and happy to answer questions and pick up items we needed for the build. I would definitely recommend Sonny and I would use him again in the future.

What to ask a Westerham extension builder before hiring?

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

An extension builder in Westerham 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 Westerham 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 Westerham?

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 Westerham 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 Westerham 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.
