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!

Chris hung a number of prefabricated doors and door frames that needed adjusting. He promptly provided us with a detailed quote and his availability. He did a job on a Saturday which was great as we really need this job to be done as soon as possible. The job was completed quickly, the adjustment to the doors are practically not noticeable and the doors and frames look great. Chris and his helper were very helpful and did a great job for us. Will definitely us Chris's services again.
