Hole in my dryer duct...
I'm new to this forum and needed some advice.
I was installing some closet shelving today and I ended up drilling a 1/2 inch hole in my dryer exhaust ducting. On the other side of the closet wall are my washer and dryer. I was drilling some holes when I noticed some metal shavings. I turned on the washer and dryer and sure enough there was warm air blowing out of the hole. I shut off the dryer and the air stopped. I looked in the attic above the wall and I could see the dryer duct is rectangular and it goes out the roof.
It looks like the wall consists of drywall, some insulation, wood, and then the duct. I was wondering what I should do to plug the hole. Is it a fire hazard? Should I have a professional come fix it? Being a novice, I'm not sure if I should start cutting away drywall and trying to fix it myself.
Any helpful advice is appreciated.
