Just had a cold call from someone offering me FREE cavity wall insulation. Apparently funded by the levy on energy companies. We're not on benefits and we're home owners. Both working with decent jobs. We have dependent kids but they're not eligible for any benefits either. All seems a bit too good to be true? Does that mean it IS too good to be true? He was offering to get a cavity wall insulation company in my area to give me a call to arrange a no-obligation assessment visit.
I've had this before, where some incompetent crowd of clowns doubled my loft insulation thickness for me (twice, because they made such a dog's breakfast of it the first time) but at least it was indeed, absolutely free, so I'm wondering if maybe this is NOT a scam after all?
As an aside, does anyone have any experience of cavity wall insulation that they'd be willing to share, please? All he could tell me is that it wasn't the "foam" type, it was the "ball" type. I've heard worrying things about condensation and penetrating damp? Cumbria is notoriously damp and our house is in a windy spot, facing the prevailing wind. A visitor once said "you don't need a porch, you need an airlock"!
Also wondering about rodents. We live in a rural area and every Winter, we get the odd field mouse.
The house was built in 1995. It already has the sort of cavity insulation that is basically about an inch of foam sprayed on to the surface of each of the concrete blocks that make up the inner leaf, but there's nothing on the mortar joints. Basically, this was applied to the blocks before they were made into a wall. I know modern builds need to use continuous sheets.
