Bathroom Fitting- 10 Nov 2013
Andy and his team did a good job replacing our bathroom and cloakroom. The job overran due to a couple of logistical problems with different tradesmen, but Andy did his best to minimise the disruption. Good communication and accurate quote, which was stuck to. Overall, we're happy with the outcome.

I recently had the pleasure of working with Iulian Isac, who built the brickwork for my driveway fence, and Iulian showed professionalism, great skill, and a real eye for detail. The quality of his craftsmanship is outstanding – the brickwork is neat, solid, and perfectly finished. He was punctual, hardworking, and kept the site tidy throughout the job. Iulian also communicated clearly, listened to what I wanted, and made sure everything was completed to a very high standard. It’s rare to find someone so reliable and dedicated, and I would highly recommend him to anyone looking for excellent brickwork.

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!
