Compared to what we have done so far, this is a fairly simple step. All of the walls are up, the sheathing is up, so the next logical step is to cut out all windows and doors. You will need a reciprocating saw (sawsall) and a drill with a drill bit larger than the size of your saw blade.

  • How to drill holes to prepare for cutting.

  • How to cut exterior sheathing.

  • How to replace exterior bracing where needed.

  • How to cut bottom plates.

Cutting Out Rought Openings For Doors And Windows.

All Rough Opnenings Must Be Cut Out From Windows And Doors.

  1. How to cut holes

    • From the interior of the house, locate the corners of the window rough opening and drill a hole at each corner.

    • Holes must be large enough to allow your reciprocating saw blade to fit through them.

    • Repeat this process at all window rough openings.

    • For Door Rough Openings, you only need to drill holes at the top corners, since you will be cutting through the bottom plate.

  2. How to cut the exterior sheathing.

    • Once the holes are cut, place your saw blade into one of the holes, and begin cutting while resting your blade against the rough opening.

    • You will be cutting out the entire rough opening therefore, which direction you choose to cut out first won't matter.

    • Cut against the wood all of the way down to the next hole. You must be careful not to cut into the wood.

    • Repeat process against headers and rough sills, until the entire rough opening has been cut out.

    • Be careful not to get hit by the falling sheet as you cut the last bit. If it doesn't fall out on its own, then knock it out with your hammer.

    • When cutting out door rough openings, cut down from the holes at each corner and cut down through the bottom plate down to the slab.

    • Finally, cut across from one hole to the next at the top of the opening. Again being careful not to have the sheet fall on you.

  3. How to brace the walls

    • As you cut out each rough opening, check to make sure the wall is still plumb.

    • Nail one end of a 2"x 4" to the inside of the rough opening and the other end to a stake outside of the house.
