Decking- 31 May 2024
Firstly they came on time and job was finished on time, I would have given 4 1/2 stars overall. There was a couple of things I would have given 4 1/2 stars for and a mostly I would have given 5 stars. They was always on time every morning and was nice and polite. Overall I'm satisfied and looking forward to completing the rest myself. I had so many nice builders come to look and price the work, it was hard to choose. I am very happy with the outcome of the work.

Hard Flooring- 2 Apr 2019
We are thrilled with our new floor! I’m so pleased we went with Treewood to lay parquet flooring in our downstairs lounge. Andrew has done the most amazing work and his attention to detail is fantastic. We moved out of the house while the work was going on as we have a baby, and Andrew kept us to up date each day with his progress and he even sent pictures. I would highly recommend Treewood to anyone needing new flooring at exceptional quality! Carly

Extension Builder in Dulwich Village
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.
