One roller of our shower enclosure door broke off. We advertised the job and only Urban doors gave us a reasonable quote. They came to look what needs to be done before completing the work. It was done as per our convenience. We are very pleased with the work.

Extension Builder in Westminster
Hello, my name is Henry, I am a 25 year old bricklayer from South east London. I wanted to become a bricklayer after learning of the history behind the bricklaying, particularly Victorian bricklayers. I often look at old buildings and think of what an honor it would be for future generations to look at my work in years to come and be proud of their ancestors' craftmanship, built with care and attention to detail that will have withstood the test of time.

What to ask a Westminster extension builder before hiring?

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

An extension builder in Westminster 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 Westminster 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 Westminster?

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 Westminster 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 Westminster 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.
