Extensions- 17 Jun 2025
I rarely write reviews, but when someone delivers work of this quality and integrity, silence would be ungrateful. Mac renovated our entire home (extension, bathrooms, utility room, flooring, lighting, staircase, landscaping, and more). We met in December, he started in February, and finished in June with steady, reliable progress. He was the first to visit, the first to quote, and a calm, principled presence throughout. He worked with us to optimise our budget and never cut corners. Mac is a European builder (ethical, family-oriented, intelligent) and sometimes brought his young son to site to show him the value of hard work. That tells you everything. He was a pleasure to have around, and our neighbours liked him so much they hired him too. Building work is never clean or quiet, but Mac made it manageable. He handled the inspector, stayed involved, and treated our home with care. We’re deeply grateful and recommend him wholeheartedly. A true professional and a good man.

Extensions- 9 Feb 2021
From the beginning of meeting Gareth and Tristan they are friendly and professional, they came to our home to build an extension and knock a wall down. They are an amazing pair. They are very skilled at what they do and they work continuously all day. They would clean up after themselves and were very unique with ideas for the build. If they came across an issue it was always resolved very quickly and affectly. They are very pet friendly as that can be a worry to pet owners when doing a big build. They also kept to their time scale even if that meant working late into the evening, but always arrived on time and were never late. Nothing is too much for them and it was a pleasure having them in our home. The result is spectacular and we are very pleased with what they have done. I would certainly recommend them to other people as they stand our from the rest.

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?

Your Cowes 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 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.

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 Cowes 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.
