Steve Scarrot built my double extension and I can honestly say, wow what a great job. I can’t say a bad word about it. Steves workmanship and knowledge on the building game is second to non. His hard work and dedication to work is first class. He was prompt, never late and did exactly what he said he was going to do. His quality of work was exceptional and he never tried to cut any corners he was first class all the way. An absolute professional and a credit to the industry and I’d happily have him work for me again.

What to ask a Barnsley extension builder before hiring?

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

An extension builder in Barnsley 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 Barnsley 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 Barnsley?

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 Barnsley 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 Barnsley 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.
