Very pleased with our finished extension. Originally we were just getting luke to do the shell of the extension but after seeing his work and professionalism we got him to do the inside aswell. We were very happy from start to finish. They are unlike other builders that come and go as they please. Luke stuck to his time scale and stayed on the job from start to finish. Would highly recommend .

Extensions- 29 Sep 2020
Kevin and his team are without a doubt the best bunch of workers you will ever meet. They work around the clock to keep us on target for the build dates. Their work is perfect and they left us with a a tidy site once they were finished. If you are having any work being done then give these guys a shout. Just keep them going with Coffee and a greggs sausage roll and they will just keep working. Happy to show you their work if you want. Thank you Kevin, Dave and Al. You made our dream home a reality. Will call on you again when we extend the kitchen 😀

What to ask a Trowbridge extension builder before hiring?

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

An extension builder in Trowbridge 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 Trowbridge 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 Trowbridge?

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 Trowbridge 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 Trowbridge 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.
