Latest review:
I recently had a full kitchen installation carried out and I’m really pleased with the results. From start to finish, the work was completed to a high standard and everything was done with great attention to detail. The installer was professional, punctual, and easy to communicate with throughout the project. Any issues or questions I had were dealt with quickly and clearly, which gave me confidence that the job was in good hands. The workmanship is excellent – everything is level, neatly finished, and exactly as discussed. They also kept the workspace tidy each day and made sure everything was cleaned up properly once the job was complete. The kitchen looks fantastic and has completely transformed the space. I would happily recommend them to anyone looking for a reliable and skilled kitchen installer, and I would definitely use them again for future work.

What to ask a Feltham extension builder before hiring?

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

An extension builder in Feltham 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 Feltham 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 Feltham?

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 Feltham 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 Feltham 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.
