Hi - we are about to replace an extractor hood with (hopefully) a quieter and more efficient and quieter model as part of a kitchen refurb.
The existing hood extract uses 100mm dia ducting thro' the cavity wall to outside. The new hood spec is for 150mm. Happy to enlarge the hole and easy to do on the inside (lightweight block) but not as easy on the outside.
The outer leaf is simulated "random" Cotswold stone i.e hard concrete block with "stone" facing. The house is approx 40 years old....
