Plastering- 23 Dec 2016
Denis did a good job plastering and retiling a small area of my kitchen. He responded to my ad promtly, came round the next day to quote and carried out the work 2 days later as requested. He was professional, polite and left my kitchen clean and tidy after the work was done. I'm happy to recommend him and would contact him again if needs be.

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.

Kitchen Fitting- 7 Jun 2020
We liked Alex from the first meeting and the first impression was spot on. Alex did an amazing job on our kitchen, which was half initiated by another tradesman. He reviewed the work and fixed many issues, always explaining and communicating well. Our kitchen had to be adapted and had some non standard cabinets but Alex was able to do all the additional features we asked for and with a great result. He also recommended some design changes which we agreed to and love. He finished the work, reviewed everything and signed off, always with a smile which is a plus. Definitely highly recommended and we will call him again in the future for sure. Thank you Alex!

Extension Builder in Denmark Hill
I am an experienced builder providing both handyman services and larger building works. My background includes loft conversions, extensions, and full property renovations, with hands-on experience from strip-out and structural work through to plasterboarding and finishing. I currently work within a construction team delivering a wide range of internal and external building projects, which gives me strong practical knowledge across multiple trades. Alongside larger jobs, I also take on general home repairs and maintenance, including furniture assembly, TV mounting, door and lock repairs, plumbing fixture replacements, sealing, and other household tasks. I’m happy to help with both small jobs and more time-consuming projects. I am reliable, tidy, and focused on delivering quality workmanship. For bigger jobs, I can arrange additional skilled help if needed to complete the work efficiently and to a high standard.
