I couldn’t be happier with the incredible job this company did on my full home renovation including the bathroom, living room, flooring and doors. From start to finish their professionalism, attention to detail and craftsmanship were second to none. The team was reliable, punctual and always kept me updated throughout the process. They transformed my space beautifully. The bathroom looks modern and luxurious, the living room feels warm and inviting, and the new flooring and doors have completely elevated the overall look of my home.

Extensions- 3 Aug 2019
Can’t speak high enough of this fella. The work he done is amazing and the standard is fantastic. Bit dubious using a website rather than a recommendation, however the price quoted was very reasonable and we went for it. Gareth built us an extension/sun room and the result is top draw. Not just a good tradesman but a really nice guy to go with it. Kept us informed throughout, gave us ideas on what would be beneficial or look aesthetically nice (from his experience). The result is beyond what we envisaged. Honestly, give Gareth a call, you will not be disappointed. Thank you Gar - we love it, the whole family love it, and the various neighbours that have been in to see love it!!!

Had a patio, decorative walls, 1.8m high boundary wall, (rendered with coping), greenhouse base, path sub-base, lawn edge and land drainage carried out. Sean turned up very soon after first contact and produced a quote within a week (even though it was over the Christmas break). Once the quote was agreed Sean turned up within a few weeks and has worked without interruption until complete. Didn't fail to turn up unless due to weather. They worked unsupervised and always did a solid days work. Always very polite and I can't find any faults with their work. Would definitely recommend him. In fact I already have to family, friends and colleagues. As a Building Surveyor I see lots of work of various standards and Sean is definitely one of the good ones.

What to ask a Llandeilo extension builder before hiring?

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

An extension builder in Llandeilo 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 Llandeilo 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 Llandeilo?

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 Llandeilo 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 Llandeilo 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.
