Dryer Vent Through Floor Joist

A 4 1 8 hole saw through the band joist drilled from the outside of the home.

Dryer vent through floor joist.

The only way to get up and out in my preferred location is to go through ceiling and make a 90 degree between floor joists and out through header joist. Whether you re installing a new vent or upgrading an existing one the first step in installing dryer vents is to determine where the dryer duct will run. The sill plate is atypical too. As for the location of the dryer vent that depends upon the dryer.

Remember the flex pipe and elbow coming out of the dryer and up down to the vent line count as elbows in the total run of the dryer duct. The dryer vent will go down into a 4d the turn right for about 4 feet within the flooring then moves into unheated uncooled attic space before the up and over and then down through the soffit with a lambro soffit dryer vent another 11 ft in the attic. It s right in front of my glass block window. Then the hole saw with a right angle drill through the doubled up floor joist from the inside of course.

Is there a way to pass through the double stringer. Except the doubling up on the 2x10 would make it an actual 3 thick x 9 joist and the hole saw is only good for 1 3 4 depth. I am trying to figure out what this is poking it with a screwdriver it appears to be hard as stone and would quickly dull my hole saw. Clamp the vent pipe to the dryer s vent outlet with a pipe clamp and tighten the clamp with a screwdriver.

I recommend keeping the duct under 12 long if possible. I have 2x8 floor joists and 16in on center so i m sure there s more than enough room in there to place the vent pipe. Yes cutting anything on the i joist is a no no and wouldn t or shouldn t pass inspection. It may be easier to take another route even if it s slightly longer.

Any ideas would be appreciated. Dryer vent installation can be a bit of a challenge. Dryer on basement floor with duct running up block wall and out rim joist. You could run 4 vent pipe parallel to the joists without any problems.

My washer and dryer are located on the second floor of a two floor townhouse with crawlspace foundation. It s basically a closet that fits the two machines only with very limited space front to ba. It looks to be more like a 4x6 with the floor joist notched and resting on it. There is room above this beam for the dryer vent but i don t want to open a can of worms.

I want to avoid a cross over and sofit where a hvac duct loops under a joist into an adjacent cavity see duct jpg.
