Hi,

I want to vent my cooker extractor hood through an outside brick wall.

My first problem is that directly above the hood is an air brick. I could only put the vent about 18", at best, from the air brick and I'm sure that the extracted fumes will find their way back into the house through the air brick.

Could I knock a hole through the air brick and put the vent through that?

Any suggestions gladly welcomed

Many thanks

David
