Extensions- 12 Feb 2025
From the first communication with Stewart this has been the most easy and amazing process.. I honestly can't praise him and his whole team enough. The process has run so incredibly smoothly and quickly it's been amazing. It's difficult choosing a builder and we worried we would choose the wrong one, worried about how it would go..but we choose the best option. I would highly recommend Chez Construction to anyone looking for builders. It's taken around 3/4 weeks give or take from start to finish. Stewart was always on the end of the phone to respond to any questions wr had and dealt with the architect and council for us aswell. We are very very happy with our new extension.

We hired Iain to complete a rear single storey extension, to create an open plan kitchen and living space. Iain and his team were very efficient and open throughout the whole build. The work was completed in less than 3 months. Iain was very approachable and informative about the process and decisions to be made, and offered expert opinions throughout the project. We have young children and Iain and his team were very accommodating to our family life and ensuring the area was safe! We are really happy with the build overall and the quality of work produced. I would highly recommend IML Building and I would definately use for future projects.

Extensions- 2 Jul 2025
We were really happy with our experience with YBF Pearson. The project was a single storey extension, and Rod project-managed it all from start to finish. He was always on top of what was going on, and communicated to us at every stage. We've never done anything like this before and so we didn't know what to expect, but we were really kept in the picture and were able to direct how we wanted things to be. The quality of the work is great, everything looks fantastic. We were able to have open discussions with Rod about budget and he was clear about what we could achieve for what we were willing to spend, and there were no unexpected costs or bumps in the road. Rod is a pleasure to deal with and overall we have come away really happy.

Bricklaying- 8 May 2026
Joe did a fantastic job for us raising our front garden wall. He came out to quote to understand what we wanted and matched the bricks perfectly for us within our budget and supported with the delivery of the bricks. Most of all turned up when he said he would and worked hard. He cleaned up after each day. This is the first time I’ve used the my builder app and with Joe. He’s a lovely young man who just cracks on and gets the job done. I will be using Joe again.

What to ask a Castleford extension builder before hiring?

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

An extension builder in Castleford 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 Castleford 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 Castleford?

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 Castleford extension builder’s ability to deliver a result that meets your expectations.
