Extensions- 11 May 2026
These guys are the real deal. So very impressed with the work that that have done. You can tell a lot about a building company with what condition they leave the building site and they left it spotless and very clean. Which lends itself to the high level of craftmanship they have put into converting my brick shed into a gym. Nothing is a problem for them and they turn up on time when they say they are and crack on with it. Mark offers recommendations for the work and due to this what I initially requested is even better than I expected. It has been a real pleasure having them on site and would offer them future work for sure.

What to ask a Eastleigh extension builder before hiring?

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

An extension builder in Eastleigh 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 Eastleigh 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 Eastleigh?

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 Eastleigh 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 Eastleigh 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.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
