Conversions - General- 22 Aug 2025
I hired Chris to install an RSJ, and I couldn’t be happier with the service. From start to finish, communication was excellent — he took the time to explain the issues uncovered during the work and talked me through the best solutions. His professionalism and problem-solving skills really stood out, especially when dealing with the poor building standards left behind by a previous builder. He also took care of building control and ensured everything was signed off properly, which gave me complete peace of mind. His team were polite, professional, and worked efficiently. The job was completed in a timely manner and with real attention to detail. I’d highly recommend Chris to anyone looking for reliable and skilled builders — a true professional you can trust.

What to ask a Bolton extension builder before hiring?

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

An extension builder in Bolton 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 Bolton 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 Bolton?

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 Bolton 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 Bolton 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.
