Local Council ad in the paper for energy efficiency, so I'm wondering
about cavity wall insulation, will it leave the outside of the house
peppered with dots !!, what size hole for injection and at what
intervals?
And are the savings worth it?
Cheers,
Just make sure you do not have a garage on the side of your house or it will
cost you about £600.
