Windows & Doors (uPVC & Metal)- 7 May 2026
Following contact with the trader and resolution of the initial communication issues, this review has been updated as a temporary placeholder while works are ongoing. At present, the customer has confirmed that communication has resumed and the project is proceeding as agreed. As the works have not yet been completed, a final review cannot fairly be given at this stage. The customer remains hopeful that, upon successful completion of the project, this review can be updated to reflect the full experience positively.

What to ask a Farnham extension builder before hiring?

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

Your Farnham 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 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.

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 Farnham 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.
