I'm hoping to drill a hole in a wall for a dryer vent. I have a concrete drill and understand the concept of drilling holes in a circle and then chipping away the rest in order to make the hole. The house is Full Masonry Brick. What I'm unsure about is if it is safe to drill a large hole through a full-masonry brick wall. I've attached a picture of the corner of the house close to where I plan on drilling. I believe the brick is in good shape and I will be able to drill nice holes through it.[ATTACH]57347[/ATTACH] I also plan on drilling some smaller holes to run new wiring into the basement, but I'm much less concerned with the impact on the structural stability losses because of these smaller holes. Thanks! New to the site, looking forward to getting some help with a few projects!

Hello, We moved to the US recently and in my native country we rarely use drywalls, usually the walls are made of concrete.. The house I rent is made of wood, drywall is used for interior. First I tried to simply use short 1" screws that were included with the window rolls, but the fasteners were absolutely not steady because the drywall is of course not hard enough. After some reading I decided to buy Drywall Anchors (plastic anchors that pop up in the end and lock themselves) recommended by many people for drywalls. But it turned out I can't screw the anchors to the full length, I think because beneath the drywall there is something harder. Hard to see but it seems it's plywood or some other type of wood. [B]It seems there is about 3/8" or 1/2" of drywall and 3/8 or 1/2" of (ply)wood.[/B] Currently I just used longer (1.5-2") screws without any anchors but [B]I wonder if there is a better way to hang my window rolls and other mid-weight things (2-20lb) on my walls?[/B] I understand I can find studs and simply use screws, but what if I need to hang something exactly where there is no stud. Kind regards, Pavel
