Liam and his team worked quickly and to a high standard to complete the job on time. Following this work we hired Liam to install worktops and storage units all made to our requirements and specifications.

What to ask a Christchurch extension builder before hiring?

What qualifications and experience do you have as an extension builder in Christchurch?

An extension builder in Christchurch 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 Christchurch 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 Christchurch?

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

How long will the extension take to complete?

Do you offer a guarantee for your work? Most Christchurch 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.
