They left foam in my water tank.

They left isolation in my after tank, I send them email and have been ignored. On other side my house is much warmer after that work done.

Hi Monika. Sorry to hear that some insulation was left in your water tank. I have searched your name in our emails and cannot see any emails. Can you call our office and we will look in to this for you? Glad to hear that your house is much warmer now.

Rated 4 out of 5 stars

Very effective insulation

We got our wall cavity insulated and our attic insulated and the difference is very noticeable. We don't have to turn on our heating half as much as we used to. When you come home you think the heating is on but it hasnt been on for hours. I am rarely cold in the house now. I would recommend the spray insulation.

Very quick and efficient

Very quick and efficient from the time we were given the quote to having the work done. Overall happy with the service and would recommend. The attic is definitely warmer, have had no mice since installation and also hoping it will solve the black mould marks we have been getting on the ceilings due to the attic being so cold and causing condensation/moisture as a result.
