I need to remove a drywall so the electrician can access it. The problem is there's a smaller board on top (towards the ceiling) and additionally, the first beam in the floor joist is on top of it. I can't see a simple way to remove the board (and put it back after the electrical work).
The wall will not be plastered or anything. There will be plywood on top against which the new kitchen will be mounted.
My thought is to cut the drywall in half approximately. Install a noggin at the seam and then screw the drywall back again. Or how would you solve it?
What should be done? If that hose is going down to a switch or an electrical outlet, cut this hole with a hole saw and open a small hole at the top. Then you should be able to maneuver a fish tape down to the larger hole. Then use the fish tape to pull up a pull string, which you then pull down the flexible conduit with.
The fish tape is stiff sideways and therefore works well to push between the board and insulation.
Need to install two boxes. One for an electrical outlet intended to be placed on the wall under the overhead cabinet. And also a connection for the dishwasher, which needs to be situated just to the right of the water pipes.
Take a Fein saw and cut off the board under the first plaster, it also works with a handsaw. If it's going on plywood on top, then it doesn't really matter how it looks underneath.
Cut out the hole where you need it. Make sure to have 5 cm free to the stud behind the drywall that remains on the wall. Then insert thin studs and screw them to the remaining drywall. Reinstall the cut-out drywall and screw it to the studs you installed.
You can also recess so-called ROT-dosor (available in single or double) from outside into the drywall and thread the cable down to it as mentioned above. ROTdosor are anchored to the board, no cross studs or braces are needed. In your case, you install them after you have mounted the Plywood, and they will then be rock solid.
Make the cut where you want, for example, cut the whole board across and unscrew the bottom part.
For reassembly, use something like lathing (28x70), 22mm boards/rough sheathing, strips of OSB/plywood that you place halfway over the cut edge in the remaining drywall, then screw back what you opened.
