Peter and his team did a super job for me insulating the attic. From the first meeting to assess the work, Peter was prompt and helpful. When the team arrived to do the work they arrived on-time, worked efficiently and with consideration for my working from home and completed the job as specified.I am very happy with the work, the price and the customer service.I can absolutely recommend Peter and his team, (and the insulation has made a difference to the house too!)

We had talked about insulating our attic for a long time and finally got it done through Fitzsimons Insulations. We were very happy with a number of things. The work was started at the agreed time on the agreed day; the time it took was exactly as we were told; the lads were very clean, left no trace behind and above all, were very easy to deal with,. Looking forward now to a warmer home and would highly recommend.
