I mention this so my clients have full confidence in me as a positive skilled builder. I have worked for 8+ years and all have been under the same boss and teammates so its fair to say i love doing what i do!! Its been a long time coming but i have finally decided to take “the leap” and start my own business so this leads me to this page.

I know to never cut corners when doing a job, always build to last and build for the correct strength needed, clean job is a happy job, problem solving not problem making, communication is key to clients and my work force and finally if any doubts always speak to my clients to make sure they are educated with the job and are happy to continue.

Conversions - General- 30 Sep 2026
Dan and his team helped me with a full refurbishment of my house, and I couldn’t be happier with the result. They completely transformed the property and made it almost unrecognisable compared with before, especially considering the timeframe they had. Was great to communicate with throughout and always kept me updated on progress. Whenever anything unexpected came up, he was helpful in finding a solution and getting it sorted without unnecessary delays. The whole team were professional, reliable, hardworking and clearly took pride in their work. The quality of the workmanship was excellent, with great attention to detail throughout. I’m extremely happy with how everything turned out and would definitely recommend Dan and his team to anyone looking for reliable, professional builders. I’ll certainly be working with them again on my next project!

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 Porth extension builder before hiring?

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

An extension builder in Porth 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 Porth 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 Porth?

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 Porth 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 Porth 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.
