We have hired Andrew to do quite a lot of work for us including replacing our conservatory and work on the exterior walls of our house. He is great, he is really friendly. I believe him to be completely trustworthy, after he had worked for us the first time I was more than happy to leave him with a house key when I went out. Andrew has always called us shortly after he has finished jobs to confirm that we are happy. I highly recommend him and give him 10 out of 10!

What to ask a Hampshire extension builder before hiring?

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

An extension builder in Hampshire 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 Hampshire 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 Hampshire?

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 Hampshire 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 Hampshire 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.
