The job was to remove a stud wall with an archway between my kitchen and hall. Pawel was excellent from start to finish. He was good to communicate with before, and answered my questions fully. He turned up on time, was very neat and kept the noise down. He did a great job and cleaned up afterwards. I’d recommend!

Groundwork & Foundations- 7 Feb 2026
Oli carried out the groundworks and demolition at my property and was on site every day with his crew, fully committed and hands-on throughout the job. I am an architect, and this was work on my own home, so my expectations were high. Oli met those expectations fully. He has a strong knowledge of groundworks and demolition, works carefully and methodically, and you can tell he genuinely enjoys what he does and takes real satisfaction in delivering the work exactly as required. He was always in a good mood, easy to communicate with, and a pleasure to have on site. I enjoyed discussing the project and hearing about other jobs he has completed over his 23 years of experience, which clearly shows in the quality of his work. I would highly recommend Oli for any groundworks or demolition works.

Plumbing- 15 Nov 2025
Incompetent company. They were contracted to put a new shower cubicle in one bathroom and regrout and make good and regrout in another bathroom. This company are completely incompetent. We had to take out all of the grouting that they did as it was so poor and all of the sealant. It was clear that they had no experience of fitting bathrooms or tiling at all. They did not even seal the sides of the shower unit against the walls, so water would be able to run right out of the shower cubicle. They did not connect the waste pipe and water came straight through the ceiling. I would not recommend this company to do any work.

What to ask a Ashtead extension builder before hiring?

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

An extension builder in Ashtead 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 Ashtead?

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 Ashtead 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.
