There has been a lot in the news recently about the Government’s green homes grant scheme, and that made me realise that I’m now facing my fifth winter since you installed underfloor insulation for me.

Before that, my long “knocked through” living room never got really warm, and on a windy night you could actually see the rugs on the floor moving up and down. Even so, I dithered for years about getting insulation because of the disruption, and the possible ruination of my varnished floor – as all the methods I’d read about required the whole floor to be taken up,

Your team installed Retrovive insulation in two days – taking up only four boards in my 35 foot room – and they even helped to move my furniture from one end of the room to the other as work progressed.

Since then, my living room has become the warmest in the house. It even retains the heat, so that when I come down in the morning the room is still warm after the central heating has been off for hours. The only downside is that I had to re-balance the whole central heating system!

I really recommend your system and can only urge other people not to wait as long as I did.
