Extensions- 21 Dec 2017
Kevin and his brother carried out a single storey extension to the rear of our property. The extension was built as per the drawings we supplied. He was happy to sort out any issues we came across and was very reliable and trustworthy, always turning up when he said he would and was very approachable and happy to explain things during the build. Would recommend for similar builds.

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.

Kitchen Fitting- 29 May 2020
From initial contact to completion of the job, Sawyers Kitchens were thorough, efficient and professional. Tommy and Jake are good, honest, highly skilled tradesmen who were a pleasure to work with. This job involved fitting a new kitchen from scratch and the guys did it with ease. Even additional jobs that were required along the way were no hassle or issue for them. I couldn't be happier with the work carried and would highly recommend Sawyers Kitchens. 10/10.

What to ask a Cowes extension builder before hiring?

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

An extension builder in Cowes 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?

What experience do you have with similar extensions in Cowes?

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 Cowes extension builder’s ability to deliver a result that meets your expectations.
