How to Cut an Opening in a Non-Load Bearing, Internal Wall
The hardest and arguably most important part of this project is determining if the wall you want to cut the opening in is a bearing or non-bearing wall.
A load-bearing wall (or bearing wall) is a wall that bears structural weight and transfers that structural weight down to the foundation or a footing. A non-load bearing or “curtain wall” provides no significant structural support beyond what is necessary to bear its own materials.
Reducing Dust:
Cutting any drywall or plaster will create dust so we’ve included some dust controlling tips and techniques. Plastic off areas and cover all furniture. Additionally use a HEPA vacuum to collect the dust as you cut or score the wall board.
Check for Wires and Pipes:
Prior to cutting any walls look at the wall for indications that there may be plumbing or wiring present. Sometimes by looking directly below and above the wall to cut you can see indication of other services inside the wall.
If still unsure make inspections holes in the wall. Remove all lines; call a plumber, electrician or gas company to have lines relocated.

Painter’s tape helps assist visualization
Layout the Opening: When trying to figure out what the opening will look like, use painters tape and mark the wall to help visualization. Once you have your opening size, measure and layout your opening by using levels to draw plumb and level lines for your opening.
Once I have determined my opening size, I used 16-inch long metal, insulation support rods to drill, at each corner, through to the opposite side of the wall. This gives me four points to “connect the dots” and draw my cut lines.
Tip – Remember to factor in additional space for jamb trim or studs, if needed to support a door or window.
How to Cut an Opening in a Non-Bearing Wall: Use a vacuum to capture dust at source
Cutting and Removing the Wall board: There are several ways to cut the opening, from using utility knives and hand saws to power tools.
I prefer to use a multi-tool because it offers more control and is less damaging to the wall surface. When using a multi-tool, have a helper hold a HEPA vacuum at the working end of the tool to capture dust.
Using a multi-tool to completely cut through the wall board all along your layout lines makes for a cleaner job and more accurate cut outs.
Once the cutting if complete, use a hammer to lightly tap along the cut lines and then use a pry bar to pry the board off the studs in large pieces. Once one piece is off, the rest can be pulled off the wall studs by hand. The wall board will break off along your cut lines, leaving you an opened cavity.

Expose all wall studs and then move to the other side of the wall and remove that wall board.

Using a reciprocating saw, cut the wall studs flush using your wallboard cut as a guide. Cut the top and bottom of the opening to remove the studs.
Adding Support for Fasteners:
Once the wall is opened you will need to determine if additional nailers or wall studs need to be added. This is useful for fastening and support if installing a door or other trim.

Prior to installing trim you will need to make and install a window jamb. I like to make my jamb on the floor or bench and install it as one piece.
Measure the thickness of your wall by hooking a tape measure on one edge of the wall and measuring to the other side, outside edge of wall. Do this all around your opening and note the thickest measurement.
Cut one by stock to the thickness of your wall thickest wall measurement. For a window opening, you will need a top, bottom and two sides to make a jamb. Measure and cut your four pieces ¼-inch short of your opening size to allow for fitting and shimming.
Butt the part together and assemble your jamb on the ground or work bench with finish nails.
Place the assembled jamb into the opening and then level and plumb it, using shims as needed. Once satisfied, fasten it into place with finish nails.
