Roofing (Pitched)- 8 Jul 2026
Really happy with the work James and the team did. From the start, James was easy to speak to, answered all my questions, and gave a fair quote. They changed our flat porch roof into a pitched roof and did a great job with the tiles, leadwork, fascia and guttering. The roof looks really good, everything was left tidy afterwards, and the whole process was straightforward. I’d happily recommend Ridgewell Roofing and Building Ltd.

What to ask a Beckenham extension builder before hiring?

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

An extension builder in Beckenham 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 Beckenham 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 Beckenham?

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 Beckenham 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 Beckenham 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.
