    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."

    "Kieran and his son did a great job repairing a crack in my wall. Shared his assessment with me and undertook the work with minimal disruption and tidied up. Only a light sand of the new plaster needed before decorating and Kieran came back without prompting to replace my radiator after I finished. Would recommend."
