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!

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!

Extensions- 11 May 2018
After a rogue builder left me with 18 (eighteen) structural issues. Lez and his crew came in transformed my failed extension into a masterpiece. All aspects of the job was done to the highest quality and utmost care and attention to detail was shown to building control needs. They cleaned up after every day and made sure the house was habitable, as I had to live there. Every aspect of the build, from the carpentry, plastering and tiling was first class and their recommend electrician and plumbers were from the same stock. Total professionals. My only regret is that I did not use this builder the first time. The prices were reasonable and even building control had good word to say about their work. Thanks Lez
