Restoration & Refurbishment- 27 Nov 2017
After a few teething problems and unclear plans from B&Q, Lee, Jacob and Artur did a very good job, not only with all the new plasterboarding, skimming, electrics, plumbing, joinery and all tiling, but also with the complete installation of our new kitchen as well. Multi-skilled tradesmen who were knowledgeable, punctual and committed to the job in hand. In the end we are happy with the finished kitchen. I would be happy to let them do further work in our house.

Extensions- 7 Nov 2023
I hired Cyrus from CTherm Ltd for our rear and side house extension and I am extremely happy with the results. Cyrus was very professional throughout the project, communicating with me regularly and addressing any concerns I had. He completed the project on time and on budget, which was very important to me. The quality of his workmanship was excellent, and he paid great attention to detail to ensure that everything was done to my satisfaction. He and his team are very knowledgeable about what they do and are well experienced. I would highly recommend Cyrus @Ctherm to anyone looking for property and extension services. Kind Regards Ash

Groundwork & Foundations- 25 Jul 2023
I needed my back yard reslabbing. All the slabs lifting up and cleaning. And a new hardcore laying. Ryan and his team worked really hard while keeping a professional role and respecting my home environment. The outcome of Ryan's work is amazing and I am so happy with the work. I can't rate Ryan and his team highly enough. If I had more work for Ryan and his team I would have them back in a flash. Anybody hiring RT Construction, you won't regret it. I don't give good reviews lightly, but Ryan went above and beyond. Thank you RT Construction.

I had Phil around to build my double storey extension on the rear of my property. He is such a polite/ friendly and easy chap to get along with, nothing was ever a problem and went above and beyond to make sure I was happy with the works carried throughout the build. The quality of his work really shows and I couldn’t be happier. When we came to the knock through into the existing house he put my family’s needs first and kept the job clean and tidy which made life so much easier to live in whilst the works was been carried out. Cannot recommend Phil enough!

Conversions - General- 8 Aug 2019
I'll start by saying i very rarely write reviews but I couldn't rate Saxon-Wells highly enough. Everything they did for us was completed in such a professional manner and with the up most care and quality. We had a garage converting into a utility room, downstairs WC and a hallway, a single extension to join original house and then walls taken out to make a big family room. Everything was done through Saxon-Wells, including the kitchen fitting, boiler moving, flooring and all wood work, etc From the very first meeting to price the job to the last piece of skirting board going down, they have completely transformed our house in to an amazing family home. I originally planned to do some of the easier work myself but for speed and quality and a more than fair price we had them do all the work. I think the sign of real quality is when things take an unexpected turn, like with any project of this size, things don't always go to plan but Saxon-Wells solved it every time amd they didn't use it as an opportunity to push the price up, they were always honest and upfront and gave their professional and personal opinions to help. We have 2 children and a dog running around the house, both Danny and Craig were always very polite and friendly to all of us, keeping the site clean and safe at all times. I really couldn't rate them highly enough. I'll be getting any future work done through Saxon-Wells and I will be recommending them to friends and family Thank you both

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

What to ask a Mirfield extension builder before hiring?

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

An extension builder in Mirfield 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 Mirfield 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 Mirfield?

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 Mirfield 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 Mirfield 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.
