WARNING SIGNS OF WATER LEAKAGE BEHIND THE WALL
PERSISTENT MUSTY ODORS
As water slowly drips from a leaky pipe inside the wall, flooring and sheetrock stay damp and develop an odor similar to wet cardboard. It generates a musty smell that can help you find hidden leaks.
MOLD IN UNUSUAL AREAS
Mold usually grows in wet areas like kitchens, baths and laundry rooms. If you spot the stuff on walls or baseboards in other rooms of the house, it’s a good indicator of undetected water leaks.
STAINS THAT GROW
When mold thrives around a leaky pipe, it sometimes takes hold on the inside surface of the affected wall. A growing stain on otherwise clean sheetrock is often your sign of a hidden plumbing problem.
PEELING OR BUBBLING WALLPAPER / PAINT
This clue is easy to miss in rooms that don’t get much use. When you see wallpaper separating along seams or paint bubbling or flaking off the wall, blame sheetrock that stays wet because of an undetected leak.
BUCKLED CEILINGS AND STAINED FLOORS
If ceilings or floors in bathrooms, kitchens or laundry areas develop structural problems, don’t rule out constant damp inside the walls. Wet sheetrock can affect adjacent framing, flooring and ceilings.
