Landscaping- 16 Jun 2026
What can I say? Blown away. Ben led a landscape project for us involving a lot of concrete breaking, concreting, fencing etc, a lot of detail, materials, deliveries, juggling stuff. The comms, the effort, the finish, the professionalism and care were just the best I've ever experienced. Which is so important when you trust someone with extensive changes to your home. Huge huge thanks to Ben and his team for being flexible and making it happen. I wouldn't hesitate to recommend.

Carpentry- 3 Sep 2020
I would recommend Ben to anyone who wants a first class piece of joinery. Ben made 2 large double doors and replaced a section of decking. He moved his work around as the job was urgent, turned up when he said he would and worked late into the evening to get the job done. A first class service. Will most definitely use him again. Thank you, Ben.

What to ask a Falmouth extension builder before hiring?

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

An extension builder in Falmouth 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 Falmouth 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 Falmouth?

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 Falmouth 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 Falmouth 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.
