I cant fault Rhidian and his team- they were professional from start to finish. It was a refreshing change to have builders that kept in touch throughout, who did the work swiftly and left the house cleaned up afterwards. They are clearly experienced and work to a high standard. They woyld be the first people I go to if I ever need more work done

Bricklaying- 19 Jun 2024
Despite bad weather the work went very well. The brickwork was of a high standard and Craig was very reliable. He was contracted to do the walls to roof level but helped with recommending other trades and supplying valuable advice about other aspects of the work and sourcing materials. Addition work was a knock through to an existing wall and installation of cavity lead flashing and trays for the roof tie in I would have no hesitation in recommending Craig and would use him for any other work that I would require in the future

Plastering- 4 Nov 2024
LMG have just completed a full silicone render of the back of our house, over 3 floors. Really pleased with the work, and the general standard of updates and quality throughout. To find a company so reliable, with such great work is really hard, and wouldn’t hesitate to use them again. Chose SeaMist colour for the Johnson’s render, and it looks amazing. Also very pleased at the scaffolding provided, and then very swiftly removed.

Groundwork & Foundations- 22 Mar 2025
Conscientious, hard working, polite, easy going and nothing was too much trouble for Mathew and Callum. From first meeting to finishing the job (including extras) they both worked tirelessly, advising me of alternatives when we came upon a problem- nothing was too much trouble for them - not a problem is their fav words. Matthew also gave me the option of sourcing and paying for supplies (unlike other builders who usually add at least 10% onto the invoice) which I loved as it kept me involved with the job and also helped me keep an eye on the budget. They also installed 2 doors and 3 windows (in a solid stone wall that was 3 foot thick) and fitted a rubber roof perfectly. I can not praise Mathew enough. If you are looking for a professional hard working reliable honest builder Mathew is your man. I can not rate him highly enough.

Extensions- 29 Sep 2025
Our job started out as a small kitchen extension and shower/utility room but grew to also include fitting of a new kitchen, new kitchen ceiling, new double glazed windows to back of house, new garden wall approximately 50ft long and 5ft high and insulation to two internal bedroom walls. Rob and his team are extremely versatile and very approachable. I would certainly recommend them and we are hoping to have some more double glazing work done in the near future.

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.

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.
