I would like to drill 2-4 holes to mount a monitor on the wall of my office. The problem is that on the other side of my plaster wall is the back of my fireplace and chimney. Can I safely drill into my wall without compromising the integrity of either of these things?

  • Is the wall drywall on the office side?

  • I'm guessing you don't know how that part of the wall is framed. Are there any vertical 2x4's behind the plaster. Typical construction for a plaster wall (depending on the age of the house) is 2x4, lathe, screed (?) undercoat, then the final plaster coat.

  • What are the chimney/fireplace made out of? Are they inside the wall, or on the other side? Commented Mar 23, 2023 at 16:07

    A picture of the wall you're drilling into, the other side of said wall, and a pic of the doorway (with a tape measure to show us how thick said wall is) will go a long way toward helping to determine an answer. You may, though, just need to start by drilling a pilot hole where one of the mounting bolts is going to go to see what you hit...
