Bathroom Fitting- 18 Feb 2026
Excellent work from Mike and his team. They kept me informed throughout with regular progress updates and pictures, which I really appreciated. They pay close attention to detail and do the job right rather than cutting corners. As a landlord, I was able to stay completely hands-off and let them get on with it. No chasing for updates or wondering if they'd show up – they were reliable and professional throughout. They started early each day, put in a full day's work, and left everything neat and clean. Would recommend and use them again in future.

What to ask a Bargoed extension builder before hiring?

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

An extension builder in Bargoed 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 Bargoed 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 Bargoed?

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 Bargoed 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 Bargoed 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.
