Hard Flooring- 16 Jun 2026
I chose Tom from a few quotes because he did the most thorough inspection and am so glad I did. The kitchen subfloor needed some extra prep work to get it level, and Tom handled it with ease. The communication was excellent, the job was completed right on schedule, and the new flooring is perfectly fitted. Highly recommended workmanship.

Extensions- 16 Apr 2026
I would not recommend this builder based on my experience. Instead of using crushed concrete they used soil to fill the house flooring for underfloor heating. 1 The project suffered from poor communication, repeated delays, and a lack of clarity around responsibilities. There were serious issues with the foundation works, which failed Building Control inspection and now require remedial engineering input before works can proceed. The site was also left incomplete and not in an acceptable condition. Despite substantial payments being made, key documentation, technical responses, and follow-through were lacking, leaving me to resolve major compliance and structural issues independently. My experience has resulted in delay, additional cost, and considerable stress. I would strongly advise others to ensure there is a detailed written contract, clear scope of works, and defined accountability

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

An extension builder in Cranleigh 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 Cranleigh?

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