Conversions - General- 30 Jan 2026
Callum responded quickly to our job request and stayed in touch throughout the process, planning an alternative day when we had to cancel due to the recent storm. He is professional and friendly and works to a high standard. We were really pleased with the finished brickwork and his clearing up afterwards. We wouldn’t hesitate to recommend Patersons Builders to family and friends. Thank you John and Alison
A Shay developments
Rating: 5 out of 5
Extension Builder in Doncaster
Over 20 years experience in the building trade, from apprentice to where I am now. Confident in all aspects of building projects from a small garden wall to a full new build house and everything in between. Great customer relationship is key, with communication throughout a project to ensure the whole job is done to the customers requirements. Although I am based in Doncaster travelling to the surrounding areas is no issue. For projects such as extensions and new builds I can fully project manage and provide trusted trades to complete electrical and plumbing works. I am no stranger to the current building regulations and all major work is overseen by LABC (local authority’s building control). References available on request from previous projects. As a small business, I thrive to offer a quality service throughout.

Bricklaying- 21 Feb 2025
Wanted the concrete steps on the front to look more appealing with better use as the old steps were not that great and a bit of an eye sore. Straight from the start A Shay was very friendly, professional and understood what we wanted. During the time from giving me a quote to the night before they arrived to do the work I was kept updated. We are really impressed with the work done and couldn’t have asked for anything more,very friendly, professional workmanship, knows his stuff and clean and tidy work. 1000% would recommend and definitely use again without a doubt.

Extensions- 2 Oct 2025
I had an extension and knock-through done, and MT Builders ( Brian and Ash) did an absolutely amazing job from start to finish. The quality of the work is outstanding, and everything was completed to a really high standard. Communication was excellent throughout the project – we were always kept up to date, and any questions we had were answered quickly and clearly. They also gave us great advice along the way, which made the whole process much smoother and helped us make the right choices. Reliable, professional, friendly and hard working, we couldn’t be happier with the results and would highly recommend MT Builders to anyone considering building work. Thank you Bri and Ash it’s been a pleasure.

What to ask a Doncaster extension builder before hiring?

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

An extension builder in Doncaster 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 Doncaster 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 Doncaster?

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 Doncaster 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 Doncaster 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.
