Extensions- 10 Nov 2025
Steve completed his work as required at the time and was professional throughout. There was a slight slope remaining, but it was a minor issue and not something I considered a major concern. Unfortunately, comments made by Probuild about Steve's work led me to question the quality of what had been done. As a customer, this left me feeling misled and confused about the situation. After learning more about what had happened, I came to understand that many of my concerns stemmed from information I had been given by Probuild rather than from Steve's work itself. To his credit, Steve remained courteous and understanding and even offered to return and help once the situation became clearer. Based on my experience, he is a genuine and humble professional who stands by his work.

Bricklaying- 5 Oct 2018
Thank you Patrick the job was completed professionally and on time. Patrick's work went above and beyond my expectations of how excellent the rebuild of a wall and installation of a window would look when completed. Patrick and his team arrived on time. I was kept informed of progress each day and Patrick and his team worked constantly throughout the day. They tidied up each day and on completion of the job. Patrick is very skilful and has great vision of how the work he does should look when finished. I would invite Patrick and his team to complete any future jobs as he is reliable, trustworthy and have restored my faith in the building trade after other no so nice experiences. Thanks once again for an excellent job, I am so pleased with the service received.

Stonemasonry- 5 Sep 2026
Really pleased with the work carried out on our property, the two fellas were fantastic from start to finish and worked really well as a team. John came up with some really innovative solutions that only someone with an extensive experience in stonemasonry skills would do, and the finished result looks great. The work was completed quickly, efficiently and, importantly, at a very fair price. Both were friendly, professional and clearly took pride in their work. We would have absolutely no hesitation in recommending them to anyone looking for similar work. We may well be getting back in touch ourselves for some further work in the future!

Extensions- 6 May 2025
Just want to take the time to say a big thank you to Carl for the new garage at my mom and dad’s house. I made it clear that I had a lot of problems with previous builders and he has definitely restored my faith. Carl turned up between 7-8am every day and gave me updates on progress. Ordered material when needed and also tried to save my parents money when he could. There aren’t many people in the trade like Carl and Im using this review to let you know you would not be making a mistake by hiring him. The work he has done is exemplary and he should be proud. Thanks again Carl, keep in touch as I’m sure I’ll have a few jobs for you in the future. Parminder

Extensions- 29 Apr 2020
Josh and his co-worker did a great job of rebuilding a brick wall in my garden and laying a sandstone patio. They had to deal with obstacles due to the coronavirus making it far more difficult than usual to get suppliers but they did their very best to get it all organised and completed it to a great standard. I would definitely use their services again if needed and would highly recommend them to others.

What to ask a Dewsbury extension builder before hiring?

What qualifications and experience do you have as an extension builder in Dewsbury?

An extension builder in Dewsbury 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 Dewsbury 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 Dewsbury?

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 Dewsbury 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 Dewsbury 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.
