Landscaping- 20 Mar 2026
Dan and his team did an excellent job carrying out some hard-landscaping work in our garden - they transformed our old patio, built a retaining wall for an embankment with reclaimed railway sleepers and installed a new fence after removing a wall. We were really impressed with the communication from start to finish and they carried out the work to a high standard in the exact amount of time planned. Dan, Joel & Alfie are also the loveliest and most respectful people you could have working on your home. I would highly recommend D.Cooper Building - thank you again!

Richard and team are absolutely one of a kind! They can do absolutely anything you can think of! It’s the first time I’ve used MyBuilder and to find Lionheart Builders, I’ve hit the jackpot! They completely put my mind at ease, very professional and knowledgeable. The work was completed to a very high standard and not to mention they are very reasonably priced too!! We’re definitely keeping their contact details for all of our future jobs and will recommend them to all our friends and family. Thank you both for such an amazing experience!

Bricklaying- 8 Jul 2026
APR Building and Construction Limited are a fantastic choice for a building company. They were quick to response with a quote and any communication regarding the wall being built. They were very attentive and eager to do the best job they could. Within a few days of confirming the task, they came, knocked the wall down and rebuild the wall to a good standard. Finally, they came and cleared all rubbish, materials and all equipment away in a professional manner. I would recommend these to other people who are looking for a good building company and we will be looking to see them again for other projects in the future.

Landscaping- 22 Jul 2026
Thanks to the team we are set to have a fantastic summer in our new garden room and freshly laid lawn! Jack listened carefully to all our ideas and gave us a really competitive price. He took the time to create a bespoke layout, knowing all it would take extra effort, just to ensure it perfectly suits our needs. The quality of the finished build is top tier! Throughout the project, Jack proved to be a honest, trustworthy, and incredibly knowledgeable guy. His attention to detail and craftsmanship are second to none. He also patiently answered all our questions in detail. Like many big building projects, we hit some minor snags (roof drainage issues and a few delays). But to his absolute credit, he took full responsibility, came straight back to carry out the remedial work, actively suggested solutions to sort everything out. While scheduling can be busy in peak season, his commitment to doing the job right was what mattered most. We’re so satisfied and wish the team every success!

Damp Proofing- 13 Apr 2026
Bryan visited my house to assess the issue on the day that I posted the job on MyBuilder. He was friendly and knowledgeable, and put me at ease. He provided a price the following day, and was able to carry out the work the following week. The two operatives that attended to carry out the work were polite and thorough, and ensured the work was carried out to a high standard. They talked me through what they'd done and answered any questions I had. Finally they cleaned up and took all mess away with them. I would highly recommend Bryan and his team for any damp/building issues you have.

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.

Will my home extension meet all building regulations and planning requirements?

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.

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 Knottingley 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.
