Tiling- 6 Jun 2026
Thief!!! Don’t hire him,he’s a crook!! He takes advantage of people who don’t know much about building(always he want to buy everything for you and steal at the end) Don’t fall for his first appearance. I’ve requested for receipt of things he bought for me,more than 3weeks and he hasn’t been able to provide it(he took almost the rest of the things he bought for me to his house ) I’ve again requested for the quote we all agreed on(which he wrote in his diary)same he hasn’t been able to provide it. I bought turbo drive screws(500 qualities) from trade point,he used less than 15 screws and took the rest to his house. Have a lot to say but I will meet him in court.

The work was quite a big project and went really well with minimum disruption. They carried out the building of a single storey extension to the house and a new brick double garage. They also included the full renovation of the existing house. New floors & ceilings, added a new en-suite , returned 2 bathrooms, new fitted kitchen, electrical rewire, plumbing and left the work in a completed beautiful finish, the work was very well managed and more than happy with the workmanship, would definitely recommend.

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.
