Hard Flooring- 22 Oct 2025
Enea did an incredible job, and we’re beyond happy with the final result. He was very accommodating, helped us choose the right tone of varnish beforehand, and kept us updated throughout the day by sending pictures of his progress (as we were both at work). Enea is trustworthy, and even though we didn’t have the chance to meet him in person, he left the flat securely, taking care of our keys and door. We highly recommend Enea!

What to ask a Brompton extension builder before hiring?

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

An extension builder in Brompton 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 Brompton 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 Brompton?

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 Brompton 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 Brompton 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.
