Hello,

Should the duct for the range hood be built into the wall or installed later using a core drill? The site manager prefers to have it built in, while the kitchen installer suggests a core drill. The kitchen installer said that building it in was common in the past, but now core drilling is preferred to easily install backdraft dampers; otherwise, it will be more difficult! However, the second kitchen installer recommends building it in.
Does anyone have any advice?

Best regards

Planned passageways do not need to be drilled; they are left open.

So, neither of the two, but a wall opening of the appropriate size, left out during the masonry work.

So, neither of the two, but a wall opening of the appropriate cross section, left out right when building the wall.

Building an opening for a round pipe with rectangular bricks?

That is probably highly inefficient. Just build the wall up and then create an opening exactly the right size. That way, it will also be properly sealed.

A matter of personal taste – I would say the same about building solid first and then perforating it: two wrongs don’t make a right. To me, that would seem like a foolish approach.

I prefer drilling. This way, you have a defined gap of a few millimeters (inches) to insert and seal the pipe. We have facing bricks, so that was a clean job and took only about 10 minutes to go through the two masonry walls.

As I said before: it’s a matter of personal preference. The two methods are opposite approaches, and from the perspective of each side, the other seems complicated and, logically, the second-best choice. Tossing a coin is a fair way to choose between these equally valid solutions ;-)
