Bricklaying- 11 May 2024
From start to finish Sion was very professional and very knowledgeable which was very helpful, in regard of how to repair and improve our garden patio. Sion replaced damaged bricks, created a new entrance to the patio and installed coping to the bricked wall. He also repointed the patio floor and added a new step.The finished result is of high standard and we love how it looks now. Sion worked tirelessly for two and a half days (in the heat ) and tidied up after, which we appreciated. We definitely recommend him and will definitely contact again. Diolch Sion

Carpentry- 22 Sep 2021
Cancelled on me late on the night before the job was supposed to start. These things happen but nice for more notice. Rescheduled work which was to replace 3 door frames and fit new doors and furniture. After a few days the doors started sticking. Informed Dion who said he wasn't in the area. I tried to be patient to allow him to pop over when in the area, but 2.5 months later he's ignoring my messages. He also hung one door on the wrong side so now i need to pay an electrician to move the light switch and pay someone to come fix his mess. I don't think he used enough fixings on the frames. Dion is a joiner in the father/son team he told me.........

Extensions- 30 Jun 2019
Dafydd came out and quoted the job straight away. He has done a fantastic job and went over and above what we expected. He even tidied up some of the hall paintwork and skirtings for us. We had a very old extension which leaked and was poorly built. The extension Dafydd has built is now not only watertight, but looks amazing! And has a lovely light shaft which really brightens it up. Very high standard of work. VERY pleased and would highly recommend him.

What to ask a Penysarn extension builder before hiring?

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

An extension builder in Penysarn 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 Penysarn 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 Penysarn?

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 Penysarn 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 Penysarn 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.
