John, thank you for the recent insulation retrofit which you completed on our home. Your knowledge of your product, your professional approach and the workmanship displayed by your full team left me in no doubt that I was getting a good job done to my home. The clean as you go approach left nothing untidy and the quality of your product with your attention to detail was evident immediately, leaving our home far warmer as a result. Thanks you for a great service. We have already recommended you to our friends.

Fitzpatrick Insulation installed our Attic Insulation. We found them to be highly efficient and professional and we are delighted with the result. We were having problems with keeping the building warm and that is now rectified. We would be happy to recommend them to anyone

We found John and his team very professional. John was hands on, has a real grasp of his work, showed real attention to detail in every aspect of the job, and was very available afterwards. He takes great pride in his work, and it shows. It was a welcome relief to finally find someone, who actually knew what he was doing, and who’s top priority was the quality of the finished job, and our complete satisfaction with the end result. I couldn’t recommend him highly enough.
D Farrell • Thomastown, Kilkenny
It was impossible to keep our house warm and with two small children was a huge concern. Our home has been noticeably warmer since (from the very first night onwards. My only regret is that we did not contact you sooner and get this done years ago.
R Limpkin • Weir View, Kilkenny
Thank you John. You provided exactly what you said you would. House stays warm for much longer after turning off heating, and is surprisingly still warm in the morning without putting on any heating. We are very happy with the installation.
T Roche • Stonyford, Co. Kilkenny
The work carried out by Fitzpatrick Insulation (attic and wall insulation) was to a high standard in terms of effectiveness, attention to detail (impossible to see where exterior walls were drilled) and cleanliness. All works carried out were done so with minimum disturbance. I am happy to recommend Fitzpatrick insulation to anyone who is contemplating having similar work carried out.
B Lorimer • Jenkinstown, Co. Kilkenny
Fantastic professional service provided by a fantastic team. Our home has seen a significant difference since the works were completed to a high quality with little or no mess. Guidance from start to finish by John made the process quick and effortless for us.
Homeowners • Callan, Kilkenny
Thanks John. Money well spent. Delighted with your work, our house is much warmer and we have turned down the heating and reduced our cost on oil. You provided excellent service, explained all details of the job, and left the house the way you found it.
M Carey • Callan, Kilkenny
Fitzpatrick Insulation recently completed cavity wall and attic insulation work at our home. They did a terrific job – a thorough review of all requirements was agreed beforehand, great attention to detail on the entire project and everything completed to agreed timescales. We believe this was definitely a worthwhile investment and we have already recommended Fitzpatrick Insulation to friends and family. Thanks again for the great job – we are enjoying a warm winter as a result of all your hard work.
R. Mooney • The Weir, Kilkenny
Best job we ever got done. Our heating bills have reduced by over 50% and job will pay for itself in a few years. We are sorry we didn’t get it done 20 years ago. House is much more comfortable and stays warmer for much longer.
