Extension Builder in Chelsea
Uz Pro Construction Ltd is a London-based bathroom renovation and tiling specialist. We deliver complete bathrooms, ensuites, wetrooms and walk-in showers through one directly-managed team — no subcontracting the job out to strangers you've never met. Every project starts with a free home survey and a fixed price agreed in writing before any work begins, so there are no surprise costs once we're on site. Tiling services: wall and floor tiling to any specification — large-format porcelain, marble and stone-effect, herringbone and metro patterns, fluted and textured finishes. We tile bathrooms and kitchens alike, whether you supply your own tiles or we do, with exact quantities specified up front. We're Constructionline Gold and SSIP accredited, and every job comes with a 24-month workmanship warranty. Our last four bathroom renovations ranged from £11,500 to £16,000 and took two to four weeks on site — real figures from real completed jobs, not estimates. We cover Central and North London and the surrounding boroughs, including Marylebone, Islington, Woolwich, Streatham and Mill Hill. Get in touch for a free, no-obligation survey and a written quotation.

Bricklaying- 16 Dec 2021
I'm very pleased with the repair that Jack carried out on my garden wall. Even though it was a small job he took the time to do it properly and ensured the bricks that had fallen down were put back straight. It started raining a little on the day causing the cement to run. Jack returned a couple of days later to tidy it up like he said he would. On inspecting the wall today I noticed that the cement on the bricks on the inside of the wall did not look as neat as how it looks on the outside of the wall. Maybe the rain caused the cement to run too much, I don't know. Overall I am pleased though and I've asked Jack to quote for another job.

Extensions- 18 Nov 2020
Unfortunately, Stuart Helm did not even start the job let alone complete it! Each time Stuart Helm was supposed to start work on the porch, he contacted me with an excuse explaining why he couldn’t start the work. This occurred over several weeks and eventually, we mutually agreed he would not be doing the work and I would repost the job. Very disappointing and lots of time wasted.

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.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
