How to Cut a Door in Sheetrock

Cutting a door in sheetrock need not be performed to exacting measurements as tight joints may cause sheets to crack when they are being pressed into place. Wood framing provides a guide for the installation and cutting of the sheetrock at door openings. Finish trim will cover at least one inch of the sheetrock around the door opening, so providing a space of 1/2-inch between your cut and the framing is recommended. Large areas such as those needed for doors and windows are best cut using a drywall saw. Keyhole saws are usually reserved for finer cuts around electrical boxes.

Instructions

    • 1

      Attach a piece of sheet rock extending from the ceiling to 2-feet below the door's header frame by screwing the panel into the door's side studs at approximately 12-inch intervals.The bottom of the door opening will be left open to reveal the framing studs beneath.

    • 2

      Leave the bottom of the door opening uncovered to reveal the framing studs. Do not attach the sheet rock to the door heading until the opening is completely cut out.

    • 3

      Measure 1/2-inch inward from the inside edges of the side frames. Mark the points with your pencil.

    • 4

      Place your drywall square against the pencil mark so that it lies parallel with the side frame. Draw a line upward to just below the header. Mark both sides of the opening the same way.

    • 5

      Place your drywall square on the marked lines and score the sheetrock along the straight edge using your utility knife.

    • 6

      Place your drywall saw through the door opening below your sheetrock panel. Saw upward along the scored line until you feel your saw hitting the header.

    • 7

      Cut both sides of the panel using the method outlined in Step 6.

    • 8

      Score the sheetrock on the back side using your drywall square and framed header as guides. Apply pressure to the cut, causing the sheetrock to break cleanly.

    • 9

      Score the paper on the front side of the sheetrock. Remove the piece that is now completely cut.
