Cavity wall insulation - holes left in wall!

[daisy5678]

Had this done today. Guys very quick (2 hours) and very nice; however, they have left a couple of the holes totally unfilled (no jokes please ) and I am guessing that it does matter as presumably if the insulation material gets wet when it next rains, it's not a good idea! Is this me being fussy or do I need to ring them to come back to fill the holes or do I need to get some concrete/ something similar and fill the holes myself?

get them back. no doubt about it

Definitely get them back. They should fill every hole as they finish.

Ta - have done! Felt a bit girly about it, but couldn't even reach one of them.

Thanks.

Was it the Mark Group?

Hopefully it's been resolved, as this is a 4 year old thread
