Drywall installation


Hello.  I have a question about drywall installation.  My house was built in the 1960’s and the walls are covered with what appears to be 3/8″ drywall followed by 1/2″ of some type of plaster board.  So the wall covering is a total of 7/8″ thick, give or take.  I am wanting to tear down this old wall covering in several rooms and install 1/2″ drywall.  My question pertains to the door casings and finished wall thickness.  As I mentioned, the current wall covering is about 7/8″ thick.  New drywall will obviously be only 1/2″ thick.  How will this affect the re-installation of the door casings and what can I do if the wall covering thickness difference creates a problem?

Thanks for your help!

  1. Hi, I would first remove some of the trim just to see if it’s laying next to the existing wall boards or if it’s on top of it. I’ve seen stranger things. If it’s on top you’ll either need to cut down the doors and window jambs, yeah lotas of work. Or pad out the walls before installing new rock.
