How to Install a Vent Hood Through Concrete Walls

By Nicole Brown ; Updated September 21, 2017

If you plan on building a kitchenette in the basement, a vent hood is essential to remove smoke, grease and odors from the area. A hood vent attached to duct work transfers air to the outside of your home and helps reduce odors more efficiently than a non-vented hood. However, choosing a vented hood may require you to run the vent through a concrete wall.

Step 1

Determine the location of the vent hood on the concrete wall above the stove. Place the hood on the wall in the desired location then mark the screw holes and outline the vent hole on the wall.

Step 2

Drill a 1/4-inch diameter hole at each screw hole mark with a drill equipped with a masonry bit. Drill a 3/8-inch hole at one edge of the vent hole outline.

Step 3

Cut the concrete along the vent hole outline with a reciprocating saw equipped with a masonry blade.

Step 4

Insert plastic anchors into the screw holes in the concrete. These anchors expand against the concrete, once inserted, to provide support for the hood.

Step 5

Run a 4-inch flexible vent through the vent hole in the concrete. Connect the flexible vent to the back of the hood. Place the hood in the desired location and insert screws through the screw holes into the plastic anchors with an electric screwdriver.

Step 6

Fit a vinyl vent cap mounting block over the end of the vent and against the exterior wall. Mark the screw holes on the concrete through the mounting block. Remove the mounting block, drill 1/4-inch-diameter holes at the marks and insert plastic anchors into the holes.

Step 7

Replace the mounting block and fit the vent cap over the block. Insert the included screws through the cap and block then into the anchors.

Step 8

Plug in the hood vent and test it to make sure it works properly. A fan is typically already installed in the vent hood, so it just needs to be plugged in.
