Extensions- 13 Apr 2024
I had a lot of work done inside the house, installing a kitchen and bathroom including the plumbing and electrics, knocking down walls and changing the layout of the rooms.The work took a lot longer than expected but was completed to a high standard. We had to wait a long time for windows which held everything up and was beyond the control of Martyn or the team.The team were professional and knowledgeable and respectful of us having to live in the house meanwhile.

Plastering- 22 Jan 2026
I hired Aries through MyBuilder and I could not be happier with the work. He went above and beyond, even helping with tasks that were not part of his job. His workmanship is excellent, very skilled, respectful, polite, and understanding throughout the whole process. There were no hidden or extra costs, and he even worked weekends to make sure the job was completed on time. I highly recommend him and would definitely use his services again. The best expereince I've had a with a builder!

What to ask a Westbury extension builder before hiring?

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

An extension builder in Westbury 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 Westbury 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 Westbury?

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 Westbury 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 Westbury 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.
