Carpentry- 29 Jul 2026
I asked Michael to do two partition walls, with two sliding doors and also sort out a water leak. he did the job brilliantly, he was always on time, always clear in explaining my options and what to do. he went over and above the instructions and was a pleasure to have him around the house. him and his team were polite, super clean, never ever left debris around and the end results were great. Also he has a great attention to details. I am recommending him highly to everyone I know and for sure will instruct him in the future.

What to ask a Purley extension builder before hiring?

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

An extension builder in Purley 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 Purley 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 Purley?

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 Purley 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 Purley 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.
