Latest review:
The job completed was a garage conversion into another bedroom. They bricked up the garage door to create a large window. Then knocking out the opposite wall to create another large window. They made a good door way into the room at the same time increasing the size of our hallway. The room was fully insulated, with plenty of electrical features before a very good plastering job was completed. During the job, I asked for additional work and they were happy to do this and quote me at the end. Both Robert and Stuart are friendly and approachable, and were happy to work round our family during the work. Having a family of 3 kids is demanding when there are building projects on the go in your home but they made the project be carried out without any stress on the family. Fully recommend them and will use them again in the future.

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.

Bathroom Fitting- 30 Jun 2025
Unprofessional and discourteous. Accepted my invitation to quote. Agreed a date and time to attend to quote. I rushed home from work to be available for the meeting. Trader didnt turn up. I sent an SMS messaged to query. No response. I sent a message on this platform to query. No response. No message to cancel. No message to apologise and explain. No courtesy. No respect for peoples time. Be mindful of this when selecting GC Home Improvement. In my experience, this kind of disregard can sometimes translate into similar disregard when it comes to workmanship.

What to ask a Brecon extension builder before hiring?

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

An extension builder in Brecon 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 Brecon 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 Brecon?

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 Brecon 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 Brecon 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.
