Transcript
00:00Someone cut an HVAC vent right in front of the door,
00:02but tearing up the floor joist to fix it would take hours.
00:06Instead, he cuts a backer board
00:08two inches wider than the opening
00:10and drives a center screw to use as a temporary handle.
00:14Heavy-duty subfloor adhesive lines the perimeter
00:16before sliding the board diagonally beneath the subfloor.
00:20Pulling it flush from the top,
00:22he anchors it through the existing plywood,
00:24creating a rock-solid bridge.
00:26The original cutout drops right back into place,
00:29making this patch stronger than the original floor.
