Bathroom Fitting- 18 Jul 2019
Chris and his team have transformed our dingy bathroom into a lovely bright and clean space, replacing our boiler at the same time. He advised on what was possible to maximise space in our small bathroom and managed the whole process taking the hassle out of it for us. No issue was too big or small and Chris went beyond the call of duty to ensure we were happy. Letting strangers into your house can be worrying but I can’t speak highly enough of how respectful Chris an his team were. We’re so pleased with the final result, we’ve already lined Chris up for another job we need doing. Wouldn’t hesitate in recommending Flo.

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!

Driveways (Paved & Loose)- 6 Jul 2026
Jeromy and his team did a fantastic job on my new driveway. They arrived on time, worked efficiently, and kept everything tidy throughout. The finish is neat, durable, and exactly what we agreed. Great communication, fair pricing, and reliable service. I’d highly recommend Jeromy to anyone looking for a trustworthy builder.

What to ask a West Ham extension builder before hiring?

Before hiring an extension builder in West Ham or extension building company in West Ham, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in West Ham?

An extension builder in West Ham should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your West Ham extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in West Ham?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the West Ham extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most West Ham extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
