JSJ have recently completed a full insulation of a large attic space in my home. There are 2 things to note working with the company. First is the Icynene product itself, which having submitted our first gas meter reading since it was fitted we have seen a 43% reduction in our monthly direct debit averaged over the year. Secondly, and equally as important, it is the standard of service that they provide. It is clear that the company as a whole take great pride in their work and their customer service. I can honestly say that after 2 days you wouldn't have known they had ever been there, apart from the house being significantly warmer!

We had our roof space insulated last year and saw a reduction in energy bills of 20% over the winter so following on from that, we had our first floor walls insulated three weeks ago to make our old draughty house properly cosy. We haven't switched the heating on upstairs yet and only a couple of times downstairs so I'm looking forward to further reductions in our energy bills! It is a lovely cosy house now. Also, it is a pleasure to have Jim and his crew in the house - very tidy and enthusiastic about the product.

I've seen these guys in action. Amazing work and filled every nook and cranny for an air tight sealed home.

Exceptional service from JSJ Foam Insulation during and after the install of Icynene under my floor. My property is an old tenement flat, cellar underneath, so it can be drafty to say the least. I've noticed the flat is significantly warmer since having this product installed.

Great product and service to match, always a pleasure to deal with.

The team were an absolute pleasure to work with from start to finish. Each one of them was passionate about what they did and in delivering excellent customer service. Our main reason for getting icynene insulation in our attic conversion, apart from having a warmer home and saving money, was to ensure our young baby would be warm enough through the night to be moved into his own room. Despite reading all the wonderful testimonies I was slightly sceptical, not believing such dramatic improvements would be achieved in OUR old house. Susan and Jim took the time to explain things and answer my questions, making sure I was completely happy before we went ahead with the installation. To make sure our bedroom is warm enough for our baby we have a room thermometer and I have already witnessed a marked improvement in the heat retention of our home. I can actually see the difference the insulation has made and no longer do we rush to put the heating on in the morning. The heating, in general, has been on much less and I our son has also been successfully moved into his own room. I am looking forward to seeing the difference in our fuel bill.

The level of service from enquiry to installation is second to none. We had our ground floor joists insulated and the guys made light work of challenging conditions, going above and beyond to make sure 100% client satisfaction....which we are! Would not hesitate recommending to family and friends Looking forward to feeling the warmer benefits this winter Thanks very much to the team at JSJ Foam Insulation

I was vey happy with the job they did on my barge. I'm looking forward to my first winter knowing it's going to be warm. All the other bargees were very impressed with it also. I can thoroughly recommend JSJ.
