Ceiling Repair: Fixing a "Stubborn" Crack Finders Fixers helps solve the mystery of the ceiling crack that just won't leave. From "Finders Fixers" episode DFFX-112

Extra support in the attic holds the key to getting rid of a recurring ceiling crack.

A mysterious ceiling crack keeps re-appearing in Scott and Teresa Taylor's house. The crack in the ceiling drywall never seems to grow, but every time they patch it, it just comes back.

In this DIY project, Tim Hockenberry, home inspector and host of DIY's Finders Fixers, investigates and finds the cause. He then shows Scott and Teresa how to fix the crack so that it won't return. The key to the fix is in the attic.

To get started, Scott joins Tim in the attic to find the crack site and sees the stress created from above. Tim then shows Scott how to properly add extra bracing tied to the ridge beam to support the center beam from sagging. They also add blocking between the joists to support drywall below.

Safety Alert: When working in a hot attic, make sure to drink plenty of water and take frequent breaks. It also helps to work early in the morning when the temperature isn't as high.

• First, clear the workspace and cover the furniture and floor with a drop cloth.

• In the attic, roll the insulation back just so that it's out of the way (figure A). Later you'll roll the insulation back into place.

• Measure the space between the joists.

• Measure and cut the wooden boards to size.

• Don't force the blocks into place. That could put more pressure on the ceiling joists and could force them to move over time.

• Cut down the boards if necessary.

• Lay each board flat against the ceiling and screw into place (figure B).

Adding Support To The Center Beam

• First, fasten plywood spacers, or pads, on the ridge beam where you'll tie in each strap. This will help keep the vertical straps plumb.

• Install the straps in an alternating pattern. Half on one side of the beams, and half on the other for added support and strength (figure C).

• Use screws to hold the straps in place. Avoid using nails because the pounding could cause breakage.
