Extensions- 13 Jun 2020
Carlos and Luzianna did our kitchen extension in 2017 and we were very pleased with the quality of the work they did. We hired them again in 2019 to redo our living room and front garden. Again we were pleased with the result. In both cases we were living in the house during the construction and they did everything they could to be considerate and clean. We would definitely recommend them.

What to ask a Amersham extension builder before hiring?

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

An extension builder in Amersham 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 Amersham 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 Amersham?

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 Amersham 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 Amersham 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.
