Byron replied to a job quickly, quote was what we have expected and he accomodated specific date we needed this done by. Communication from the beginning until the end was great, he explained everything clearly, advised day before what time will they be arriving and arrived in time. Did a fantastic job plastering living room ceiling and cleaned up the floor afterwards as well. Very pleased and will definitelly be employing again for any future jobs. Thank you!

What to ask a Uxbridge extension builder before hiring?

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

An extension builder in Uxbridge 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 Uxbridge 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 Uxbridge?

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 Uxbridge 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 Uxbridge 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.
