"Kieran was a delight to deal with from speaking on the phone to arrange a quote to completing the job. Such a nice guy, he totally understood what I needed, didn't over complicate things, completed the job within a few days of the quote and it was done to an excellent standard at a very fair price. I recommend Kieran very highly"

"A previous builder never finished the work and left us in a bit of a bind with an annexe we were building in the back garden. I found Kieran on TrustATrader and he met with my wife and I on very short notice. He quickly came up with a plan and a cost (which did not increase), and dates for when he would finish. He did everything he said he would, when he said as well, and given the stress that the previous builder left us with, was very much appreciated. The quality of his work is unquestioned, he even had other contacts for other things we needed and organised all of that as well. 5 stars! Easy to give in this case. And very affordable. And a nice guy too! Thank you Kieran!"

Gary - Image 1 "Kieran did an amazing job. His quote was very reasonable and he was able to start the job promptly. Him and his assistant arrived every day spot on time. They worked neatly and respectfully. He is very friendly and helpful and always on hand to offer advice and suggestions. I would not hesitate to recommend Kieran, and I will definitely be using him again for my next project."

Bernie Moriarty - Image 1 "I just want to say how thrilled I am with the work done on my new bathroom. From the very first conversation, Kieran was clear, honest, and upfront about everything — no surprises, no stress. He and the team talked me through each stage as they went, and were always happy to explain things or adapt where needed. The quality of the work is absolutely top-notch, and it’s made such a difference to my home. But just as importantly, they were a genuinely lovely bunch — respectful, friendly, and easy to have around. I felt safe, listened to, and really well looked after. If you’re looking for tradesmen who are trustworthy, reliable, and take real pride in what they do, I wouldn’t hesitate to recommend Kieran. Thanks Kieran for a fantastic job."
