Bricklaying- 26 Sep 2026
An exemplary service from this firm from the very first contact through to the end of the job. Josh was attentive and quick to respond via email while we were discussing the job, the materials and the quote. He gave a us a full breakdown of the work beforehand, along with generated images of what the finished product would look like, so there were no unpleasant surprises later on. The quote itself was competitive and was definitely the most detailed and professional one we received. We chose them because it felt like a safe pair of hands, and they didn't let us down. Josh and his team turned up when they said they would, were polite, courteous and respectful of our property and our neighbours and cleaned up after themselves very well. The work itself was done to a very high standard, and we're really happy with the results. We would recommend them to anyone, and will likely use them again.

Extensions- 31 Dec 2021
Fabulous job. Turned up on time to quote — professional, polite and prompt every time. Kept communication going throughout the build and gave his experienced opinion on adjustments and problems. Got the job done, while being conscious that we were living in a small space while the work was happening. Beautiful brick work and an artistic eye, which is hugely helpful on a small but important build. Did the work within timescale and budget quoted. Only employs other reliable, high quality tradesmen to work alongside him. Can’t recommend highly enough. Old school values and skills which is just what was needed. Book him in if you can as workmen like him are in short supply.

What to ask a Wiltshire extension builder before hiring?

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

An extension builder in Wiltshire 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 Wiltshire 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 Wiltshire?

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 Wiltshire 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 Wiltshire 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.
