I couldn't recommend Fitzsimons Insulation more. They were organised and professional throughout. They really did a great job insulating my attic which was not an easy job and it was priced very reasonably for the work involved.The crew went above and beyond to make sure all areas were insulated properly even if it was very difficult to access. I could feel our house was instantly warmer and easier to heat when the job was complete.Great work!

Fitzsimons were very easy to organise insulation with. Along with that all the insulation work was done to a high standard and quickly. If anyone needs insulation this is where I would send them!

Attic Insulation & part flooring with shelving. Very happy with Peter and the team and the work carried out. The difference in the heat retention is amazing. Highly recommend.

Highly recommended. Very professional from initial assessment to completion of the job. Noticeable difference in heat retention straight away. We got cheaper quotes, but it was clear from the start that Fitzsimons were much more thorough. Some vendors did not even come into the house when quoting, but Peter came, showed us the areas where heat was being lost and talked us through the process. Once we decided to proceed, work was scheduled promptly and the team came when promised and carried out to a high standard.

What a fantastic service! Peter and his team were very kind and they cared about every single detail.On the day of the service, Peter popped up to make sure that the crew knew exactly what needed to be done, which is a plus.At the end, the lads called me to make sure I was happy with the insulation before they leave. They also left the spot spotless like if nothing had happen at the house. Brilliant work.Photos: check out the pre/post insulation. Solid work!!I highly recommend them.

I would just like to share the fantastic experience I had using Fitzsimons Insulation. Peter was very professional, knowledgeable and courteous. The installation team were on time, did an amazing job and left the place spotless when they finished. Peter called back to check I was happy with the completed work and Michelle and Susan in the office were lovely to deal with. You can tell it’s family business from the passion and pride in their work. I give this company 5* rating.
