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.

Gelu is hard working and dependent guy, will not fuss about the job like many do, but will crack on with it. Stayed late to finish it at many times. I am quite happy with the finish and work. shower fit, washbasin, toilet, tiling all done to my satisfaction. After seeing the work I asked him to do more like kitchen cabinets and skirtings.

Extensions- 19 Sep 2022
Man Ho or Calvin Ho' or Man Fu Ho, who owns Carve Engineering Co. Ltd. He also has a Hong Kong branch carve-eng.com . I didn't know he subcontracted the whole project to a group of Chinese mainlanders who couldn't speak English. And he asked a British Gas gas engineer to sign off the plumbing work. I obtained the planning in December 2021. The work started on 31/1/2022 and almost finished now 19/9/2022. It supposed to end in three months time as they promised. It's only a single storey side extension and shouldn't be left unfinished with pipes broke. The workers only came to work once a week and sometimes the work stopped for a month or so. The price included the purchase of a boiler and installation. But there's no timer or thermostat and I was asked to purchase these and install them with extra cost. The workers' van broke down five times and they didn't turn up for five different days. There's no windowsill and they called this a standard window people would install. The exterior wall was painted inconsistent to our original wall and I had to argue to get them pebbledash and repainted. They left the fences on our neighbours. The pipes are still leaking. Shower leaked for 3 months. They even charged extra for the electricity sockets they installed in our kitchen. They took down the mains water supply switch and never install it back so our house has no in house mains water stop valve! They didn't hoover and didn't have a hoover. Avoid this company!
