Ceiling and Drywall Removal After Water in Syracuse

Why must wet drywall come out instead of drying in place?

Wet drywall loses its strength and holds moisture in its core and its paper facing, so it cannot be dried to a safe level in place. Once the board is wet to the core, it is removed and replaced.

Gypsum board is made to hold a surface finish, not to stay wet. Water breaks down the bond between the core and the paper, and the board can then sag, crumble or grow mold on the back. A board that reads wet to the core will not return to its original strength by drying.

A board that is wet only at its surface and reads dry at its core may be left in place. The crew makes that decision from the readings, and records it, so the owner knows why a board stayed or went.

What is the wet line, and how is it found?

The wet line is the highest point on the wall or ceiling where the moisture reading is above the dry level. Cutting a short distance beyond it removes the wet material and leaves the dry board in place.

The crew uses a meter at a series of points up the wall to find where the readings change from wet to dry. Each point is marked on the wall with a pencil so the cut line is clear. A stain above the line does not mean the board is wet there, since the stain may be dry.

The cut is made a short distance beyond the wet line, so that no wet material is left behind the edge. The cut line and the readings are photographed and recorded for the owner.

What happens to insulation above a wet ceiling?

Insulation that holds water loses its ability to insulate and can hold moisture against the framing. It is removed where it is wet and replaced once the cavity is dry.

Fibrous insulation absorbs water and holds it, and it cannot be dried in place to a safe level. The crew removes the wet insulation from the affected bays and bags it for disposal. The dry bays are left in place where they read dry.

The removal is recorded by bay, so the owner knows what was taken out and where. The replacement insulation is installed by the trade that does the rebuild, after the framing has been read and found dry.

What should a homeowner do with the ceiling before the crew arrives?

Place a container under the lowest point of the stain, move furniture out of the room, and keep people away from the area under the ceiling. Do not push on the sagging board or try to drain it by yourself.

A container placed under a drip catches the water and slows the spread across the floor. Move the furniture and electronics out of the room, and cover anything that cannot be moved with plastic sheeting placed above it.

Take photographs of the stain, the sag and the water on the floor before anything is touched. The photographs are part of the record the insurer will ask for, and they show the condition of the ceiling when the crew arrived.

• Furniture and electronics moved out of the room
• Anything left in place covered with plastic from above
• Photographs of the stain and the sag before touching the board

How is a drywall repair finished after the drying?

Once the cavity is dry and checked, the new board is installed, taped, finished and painted by the trade that does the repair. The work should match the existing wall and meet the local building rules.

The new board is cut to fit the opening, fixed to the framing and finished with tape and compound. Priming is done before the final paint, so the stain from the old leak does not show through. The finished surface should be checked for any lingering moisture before it is painted.

Ask the trade to note the dry readings and the work done, so the file holds the record of the repair from the drying to the finish.
