Extensions- 8 Oct 2025
Jason and his team have just completed our wraparound extension, and the result has exceeded all expectations. Their workmanship, accuracy, and attention to detail are outstanding, and the whole process was smooth and stress-free. They stuck to timings, kept the budget in mind, and made everything feel effortless. Partway through the build, Jason had to undergo an operation and was signed off for five weeks. Remarkably, nothing was delayed — his team carried the project seamlessly, and with Jason still on site when he was able to be, everything ran perfectly. It’s a real credit to how capable they all are and the consistently high standards they work to. The only negative thing I can say is that we were sad to see them leave – they’ve been such a positive part of our daily lives over the past eight weeks. The finish is exceptional and we’re absolutely over the moon. We couldn’t recommend Jason and his team highly enough.

On visiting to quote Andi impressed us with his professionalism so he was awarded the job over two other applicants. The job was completed on time and to an agreed specification. He was not the least expensive quote but we are happy that we chose him. If I had any further work I would happily employ him again.

Disappointingly all the door linings were fit incorrectly and as a result, no door handles and locks are flush. Didn’t come back to rectify mistakes around the house and stopped responding to messages.

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

An extension builder in Farnham 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?

What experience do you have with similar extensions in Farnham?

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