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.

Myself and my partner had a positive experience with Justin and the team, the three directors initially came out to our house and assessed the job, we immediately had a good feeling. We subsequently received the quotation not too long after and together we made some tweaks before giving them the go-ahead. Communication was good throughout the project even with material delays and unexpected issues with the build, we also added some extra works throughout the project which was accommodated and costs discussed. The project did run over slightly but that was due to the latter. The guys were a pleasure to have on site as well as any subcontractors that were used. We are really happy with the finished project. The extension has made our space into a now useable family home, we love it!

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.
