Ryan recently built a small brick wall for me, and I couldn’t be happier with the result. He turned up on time, was clean and tidy throughout the job, and was always polite and helpful. Ryan was clearly very knowledgeable and completed the work efficiently and to a high standard. The whole experience was great from start to finish, and I would happily recommend his work to anyone looking for a reliable builder.

Loft Conversion- 12 Dec 2017
Mark and Will did an amazing job. They communicate well throughout and tried their very best to not disrupt the house. Though this sort of work is major and takes a lot of time it was a pleasure to have them around. They are always cheerful and I was happy for them to have access to the house to work while I was away at work. Top job, I highly recommend them.

What to ask a Bath extension builder before hiring?

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

An extension builder in Bath 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 Bath 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 Bath?

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 Bath 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 Bath 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.
