What to ask a Belsize extension builder before hiring?

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

An extension builder in Belsize 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?

What experience do you have with similar extensions in Belsize?

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 Belsize extension builder’s ability to deliver a result that meets your expectations.
