Hi,
I would be grateful if you could advise me on the replacement of my existing bathroom extractor fan. The wiring is no problem, I would like to know which sealant has been used to firmly secure it in the circular hole. obviously when replacing I would like to replace the sealant like for like.
With thanks
Paul
