Extensions- 8 Jan 2025
I contacted A1 builders for a quote on an extension inside kitchen area renovated with new fitted kitchen installed. The quote was fair and we did come into some complications but it was rectified. Workers were polite and friendly although a little untidy but the end result far exceeded my expectations and I’m very happy with the work and will use A1 builders again.

Extensions- 4 Jan 2020
On budget. On schedule. Resulting in a stunning kitchen extension built by two delightful, highly skilled, creative, flexible, resourceful craftsmen who were open to incorporating ideas as they worked. We were impressed from the outset by the extremely detailed quote that was presented to us by Richard and Ian which included a complete breakdown of all materials and labour, almost to every nail and screw. It gave us the confidence to know there would be no nasty surprises along the way. Working to our plans, they dealt with any obstacles that they encountered during the build by suggesting clever, practical solutions, always mindful of our vision. Work began on the agreed day and both Richard and Ian came every day without fail until completion. We could tell from the outset that they took immense pride in their work and constantly checked that we were happy with the quality and progress. For such a large extension, they managed to keep disruption to an absolute minimum and impressed everyone with an incredibly clean and tidy site. We are thrilled with our new space and everyone loves it. We cannot thank Richard and Ian enough for their hard work and professionalism. We actually enjoyed the experience and really missed them when the work was completed, they became part of our family! We cannot recommend them more highly and consider ourselves very fortunate to have found them.

Bricklaying- 8 Oct 2018
Kieran was on time for his visit to quote and started the job on time on the day he said he would - no delays. His work is spot on and he talked me through everything he did. He pays attention to detail and has excellent customer care - cleaned up after himself and left the property neat and tidy. Trusted him with our keys while we were away. The quality of his stone work is excellent and his prices very reasonable - quote for the job and not the time it takes - this is the biggest thing for us as the price is never a worry . I`d recommend Kieren as a very conscientious and punctual tradesman with high quality work and an excellent finish on the job.

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

An extension builder in Cwmbran 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?

What experience do you have with similar extensions in Cwmbran?

Do you offer a guarantee for your work? Most Cwmbran 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.
