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.

My immediate impression of Luke was that he is extremely professional in his manner and way of working.

Extensions- 17 Aug 2020
Justin did a great job on our small extension and kitchen knock through. He saved our backs after our original builder had let us down and was able to take on the project quickly for us. We heard back from him almost immediately after coming to look at the job and work started soon after. Justin and Craig worked very hard to get the work done and despite our old wonky house throwing in some extra challenges along they way (thanks Victorian builders!), the job was done within the timescale and for a good price. Justin kept us in the loop throughout the project, making sure we were happy with everything and communication was great. We were able to discuss any questions we had and Justin even gave us advice on other parts of our house renovations that we are undertaking ourselves. Justin and Craig were very reliable and showed up when they said they would. They are also probably the most respectful tradesmen we've ever encountered! Always being careful to tidy up after themselves and going above and beyond to keep disruption and mess to a minimum. We would not hesitate to recommend Justin or use his services again in future!

Handyman- 14 Jul 2018
Would not recommend. Grouping poor & cracking, tiles not flush causing build up of grime. Cases not fixed properly. Chipped window sill. Flooring starting to move. Didn't want to leave feedback but 2 years on and we are having to have things replaced. Don't want to ask them back as getting them to replace our bath they broke was drama enough. A lot of money spent on this project we'd of never expected to have to touch it for years. Very disappointing

What to ask a Gwent extension builder before hiring?

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

An extension builder in Gwent 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 Gwent 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 Gwent?

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 Gwent 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 Gwent 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.
