Loft Conversion- 11 Jun 2026
We recently completed a loft conversion with Dean and his team at Blakeon, and I couldn't be happier with the result. The workmanship has been excellent throughout, and the new loft space has completely transformed the house while feeling fully integrated with the rest of the property. What really stood out was the communication, reliability and flexibility. As the project progressed, I refined several design decisions before they were finalised, and Dean was always patient, accommodating and willing to discuss options. The project included a number of additional complexities, all of which were handled professionally and pragmatically. I also remained living in the house throughout the build, and the team were consistently respectful, considerate and easy to work with. I would have no hesitation in recommending Dean and his team and am already discussing future projects with him.

Extensions- 3 Oct 2022
The Guys were great, excellent work, put the hours in to get the job done, 99% of the work is done they're just coming back to install the windows once they've been manufactured. But the rest of the work, I can't fault it having had a terrible experience whilst building the house a few years ago these guys went above and beyond, and proved there are good builders around. Great attention to detail and skilled. Would happily recommend them and use them again on future building projects.

Bricklaying- 3 Dec 2021
Paul did a fantastic job taking down my existing 30m fence and replacing it with a 2m high block wall, and rendering it to my chosen colour. Paul listened to every request I had and carried them out perfectly. He managed to put a really nice curve on the wall rather than the normal stepped approach, which I was less keen on. He managed to save a fir tree and line of bamboos that I felt sure would be impacted or need removing during the building work. Paul and Rob cleaned up after themselves every day, and were very respectful nice chaps. The job did take longer than expected, but each delay was beyond Pauls control, and overall I am delighted with the result.

Excellent completed work from Walid. Friendly, fast and polite communication with every question I asked, the work was booked in quickly and completed, and Walid even added in additional work when I asked him, with very fair pricing. I highly recommend Walid and have asked him to quote for some new work.

What to ask a Cowbridge extension builder before hiring?

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

An extension builder in Cowbridge 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 Cowbridge?

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 Cowbridge 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 Cowbridge 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.
