Damp Proofing- 11 May 2026
My experience with Samuel was excellent. He provided a professional, comprehensive, and high-value damp survey for my basement. The final report was very thorough, including a detailed technical assessment and numerous photographs that clearly explained the situation. What really stood out was his willingness to answer several follow-up questions regarding the specific remedial work he suggested. His expertise helped clarify that the issues were environmental rather than structural, which provided great peace of mind. Highly recommended for anyone needing a clear, honest, and professional assessment.

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

An extension builder in Hounslow 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 Hounslow?

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