Bricklaying- 26 Jul 2024
The whole job was done in a very organized way from the materials delivered, and the demolishing of the old wall, old materials taken away immediately and building commenced. Garry even got us some fine weather to complete the fantastic work along with some added extras that were the icing on the cake. Everywhere all cleaned up and left tidy when finished each day and at the end of their work. I would recommend this guy and his team anytime. Thank you for referring him.

Extensions- 18 Jul 2026
Great service from O&C construction. Had them here to help remove some old footings and to dig out the new ones for our extension. Punctual, they were here on time or early every day, which is nice. Knowledgeable gave me loads of advice and helped with building control when that was needed. Clean considering what we were doing they were very respectful of the location and surrounds. We have a lot of neighbours and not one had a bad word to say about the works we have done. Highly recommend and would use again.

Decking- 8 Jan 2019
WARNING!!! We hired joseph and his company to do some garden works for us. He seemed a genuinely nice guy and prided himself on the fact his company had been on tv doing DIY SOS. How they got the job i will never know!! After taking a VERY large deposit from me the work commenced, it was an absolute shambles. Extremely poor workmanship, turned up when he wanted and sometimes it was just his apprentice. After 2 weeks and the garden not even half done (eventually had a proper landscaping company do the works in only 3 days), Joseph failed to turn up again. He blocked our numbers, failed to respond to emails and from doing some research it turns out i am on a long list of clients he has done this too!! Please beware of any company Mr Joseph Keatley is involved with, he might seem genuine to begin with but that soon changes when he has taken your money!!!!

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 Rotherham extension builder before hiring?

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

An extension builder in Rotherham 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 Rotherham 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 Rotherham?

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 Rotherham 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 Rotherham 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.
