Bathroom Fitting- 26 Jul 2024
Catalin completely transformed both bathrooms! He listened to our requests and has come with good solutions to our problems, including recessed shelves and replacing the hot water cylinder with a combi boiler, to give us more space in the bathroom. The work was done to a very high standard and has helped us to source materials and sanitary ware. Catalin and his team has done a fabulous job! I highly recommend him!

What to ask a Barnes extension builder before hiring?

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

An extension builder in Barnes 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 Barnes 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 Barnes?

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 Barnes 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 Barnes 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.
