Extensions- 29 Feb 2016
John was impressive, he delivered on all aspects of the work and did make attempts to make sure snags and workmanship was of an acceptable standard. Where he contracted work out, it was good quality delivered, especially in terms of the brickwork to the main extension, windows and roofing including Velux windows. However some of his general labourer workman did not deliver a good quality of work, resulting in a patio area needing to be relaid by another contractor at cost to myself, poor quality brickwork on the garden retaining walls and when digging the foundations for the extension damage to drainage pipes, with a poor attempt at repair. As a result of this we have had the pipe block three times and have been told it will need to be replaced as it is collapsing.

Landscaping- 22 Jul 2026
Thanks to the team we are set to have a fantastic summer in our new garden room and freshly laid lawn! Jack listened carefully to all our ideas and gave us a really competitive price. He took the time to create a bespoke layout, knowing all it would take extra effort, just to ensure it perfectly suits our needs. The quality of the finished build is top tier! Throughout the project, Jack proved to be a honest, trustworthy, and incredibly knowledgeable guy. His attention to detail and craftsmanship are second to none. He also patiently answered all our questions in detail. Like many big building projects, we hit some minor snags (roof drainage issues and a few delays). But to his absolute credit, he took full responsibility, came straight back to carry out the remedial work, actively suggested solutions to sort everything out. While scheduling can be busy in peak season, his commitment to doing the job right was what mattered most. We’re so satisfied and wish the team every success!

Extensions- 7 Oct 2026
We originally had DSF come and revamp our porch and ended up asking them to do our garage conversion too! Dean and his team are friendly, honest and keep you up to date with how the work is progressing including timescales, costs and any changes. The site is kept clean and tidy and has been left like it was when they first arrived. Great attention to detail and kept in the loop every step of the way. Highly recommended and will definitely be getting back in touch for a couple of other projects in mind for next year. Thanks again!

Extensions- 11 May 2022
Craig has recently completed a garage to kitchen extension with an added downstairs toilet and utility room. The whole process has been positive, Craig was confident in his quote and advise but was keen to listen to our ideas and was happy to discuss various options around budget and function etc. Craig's initial quote was agreed and didn't differ, although I appreciate building materials may have increased during completion, which made the whole project manageable and we weren't worried about hidden charges etc. I would highly recommend Craig and he also has great contacts within the industry for electrical, plumbing, roofing and windows / doors to ensure all jobs are completed to standard.

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.
