Ceiling Leak Water Damage in Manchester, NH

In a city full of two- and three-family houses, a ceiling leak is often somebody else's water. A tub that overflowed on the third floor, a toilet supply line in the unit upstairs, a washer drain hose or a leaking shower pan all end up in the ceiling below. Inside a single-family house the usual sources are an upstairs bathroom, a laundry room or a heating pipe running through the floor.

Signs the ceiling is holding water

• A brown ring or spreading stain, often darker at the edges
• Paint that bubbles or a drywall seam that sags
• Water dripping from a light fixture or smoke detector
• Cracks opening in old plaster, or plaster that sounds hollow when tapped

A sagging ceiling can hold a surprising amount of water and can come down without warning. Keep people out from under it.

How ceiling water damage is dried

The tech who does the walkthrough traces the water back to its source with thermal imaging and pinless meters, often from the floor above. If a ceiling is bellied with water, the restoration team drains it in a controlled way before it fails. Drywall ceilings that are soaked or sagging usually come down in the wet section. Plaster on wood lath is heavier and holds water longer; sometimes it can be dried in place with a small opening, and sometimes loose plaster has to come down for safety.

With the bay opened, air movers and LGR dehumidifiers dry the joists and subfloor above. Wet insulation in the bay is removed. Readings are taken daily until the framing matches a dry reference in the same building.

When the leak starts in another unit

In multi-family buildings the source unit, the unit below and sometimes the building owner are all part of the claim. Photos, the moisture map and daily readings show where the water came from and what it reached, which helps every party sort out coverage.
