Extensions- 14 Nov 2025
I hired Reliable Roofing and Building to build a rear extension at my property. Unfortunately, the project did not progress as agreed. Communication became very inconsistent, and several promised return dates were missed. Despite the next milestone not being reached, I was repeatedly asked for early payment. When I refused Jamie was aggressive and threatened to knock down the work. Due to all the issues I decided to remove them from the project. Due to concerns about the quality of the work, I arranged for two independent professional inspections. Both reports stated that the structure was not built to an acceptable standard and would need to be demolished and rebuilt. Following this, I asked the builder to refund the amount paid, but no refund has been provided. I issued a formal request for repayment and have now begun the court claim process to recover the losses. The company has been reported to trading standards and MyBuilder. I do not recommend using this company.

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.

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.

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

An extension builder in Knottingley 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.

What experience do you have with similar extensions in Knottingley?

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