Cavity wall insulation removal
Anonymous user 17/03/2026 - 3.11 PM
I have CWI which i am pretty sure has failed. Do companies come out & do inspections to check or is it something i could do myself. I'm assuming it's just a matter of drilling a hole into the cavity & putting a camera through, or would using a camera that shows up any heat loss be better. Is CWI better nowadays than it used to be? Many thanks
