Cavity Wall Insulation

Pistorius

I own a semi detached property, and have obtained quotes for cavity wall insulation and loft insulation.

Installer is happy to do the loft insulation, but cannot insulate the cavity walls because our adjoining neighbour has had their cavity wall insulated and the material has spilled onto my side of the boundary. The installer advises that their original installer should have put up a divider to stop this exact problem, but because they haven’t, they are now obliged to return and insulate our cavities for free. The installer states he cannot do it himself as the material he uses may cause a chemical reaction with the unknown material that the adjoining neighbours installers used.

I have spoken to the neighbour (tenants) and asked them who who they used to do the original CWI. She cannot remember. She has called and emailed her landlord as he might have records, but he doesn’t answer or respond; which she says is normal for him.

I’ve requested land registry details to write to the landlord myself. Sadly his address is listed as the property address despite the fact it is tenanted. All I have is his name and mortgage lender.

I’ve contacted CIGA to see if they hold the certificate for the installation = negative.

I spoke to local building control as it should have been notified at the time = it wasn’t.

I’ve spoken to 5 other insurers who provided guarantees for CWI to see if they hold any details about the installation = negative.

I’ve called the landlords mortgage company to explain the problem and the fact that the owners address details are incorrect on land registry, but they cannot contact him on my behalf due to data protection.

It’s proving impossible to find out who did the original CWI, impossible to get in contact with the owner and impossible to find any installer willing to insulate my side of the property with the current overspill.

Any ideas?

Even if you find them, they aren't going to insulate your house for free, I don't know why he said that.


You could look at using polystyrene balls as an insulator, instead of a sprayed chemical

But before you go ahead with it try googling it or looking on this forum for threads relating to Cavity Wall Insulation,there were several all complaining about damp problems and trying to get some sort of remedial help.

Cavity wall insulation in our old house made it way too hot in summer, wouldn’t have it again personally!

Ours used to be too hot in summer and too cold in winter. Now with CWI its reasonable all year round.

Im guessing you have a lot of south facing windows?

I was under the impression this had been largely resolved. I thought it was the early CWI jobs that hadnt been correctly assessed for its suitability that caused problems and since the problems started companies are now required to assess and guarantee that assessment?

Im not certain on this but thought it had moved on a bit, anyone know or confirm?
