Extension Builder in Chelsea
Hi, I’m a skilled and reliable multi-trade construction specialist with several years of hands-on experience across a wide range of domestic building work. I originally started as a handyman and have since developed a strong all-round skill set through practical on-site experience. My main areas of work include kitchen fitting, bathroom installations (including toilets, showers and fittings), tiling, flooring, media walls, patios, and painting & decorating. I also have experience in general building and repair work, which allows me to take on a variety of projects from start to finish. I hold qualifications in bricklaying and plumbing from City & Guilds, which support the practical experience I’ve gained working on real projects. This combination allows me to deliver work that is both structurally sound and finished to a high standard. I take pride in being punctual, tidy, and easy to communicate with. I understand how important it is for customers to feel confident in who they hire, so I always aim to be clear with pricing, honest about timelines, and committed to delivering quality results. As I’m currently building my profile on MyBuilder, I’m focused on providing excellent workmanship and earning strong customer feedback.

What to ask a Chelsea extension builder before hiring?

Before hiring an extension builder in Chelsea or extension building company in Chelsea, 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 Chelsea?

An extension builder in Chelsea 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 Chelsea 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 Chelsea?

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 Chelsea 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 Chelsea 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.
