I was recommended Bear Construction by a friend, and it turned out to be an excellent suggestion. From the initial consultation with the architect to the final handover, Bear Construction provided an exceptional experience. Here are the key highlights of working with them: Smooth and Transparent Communication: Each step of the process was clearly explained, and I received daily progress updates, which I found incredibly helpful and reassuring. Respectful and Considerate Team: The work site was kept tidy and well-contained. My neighbours also mentioned how respectful the team was, which was especially important as my property is mid-terrace. Impeccable Quality and Efficiency: The project was completed to an exceptionally high standard, and impressively, it finished three weeks ahead of schedule. I couldn’t be more pleased with the results and would happily recommend Bear Construction to anyone seeking reliable and high-quality building services.

Extensions- 1 Jun 2022
We are absolutely thrilled with our extension. Elliot and the team completed all elements of the project, which included numerous steels to replace existing supporting walls and the re-fit of our existing kitchen +new kitchen fit out. The work is finished to a very high quality and far exceeded our expectations. Product selections such as doors, windows and tiles were proposed by Elliot and were exactly what we wanted. Elliot and the team were professional and a pleasure to work with and we would highly recommend them.

What to ask a Petworth extension builder before hiring?

What qualifications and experience do you have as an extension builder in Petworth?

An extension builder in Petworth 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 Petworth 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 Petworth?

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 Petworth 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 Petworth 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.
