Here are some signs you should be aware of and look for to determine whether or not there is water damage present:
1. Odors
When hidden water goes unnoticed for prolonged amounts of time, it will begin to foster mold and bacterial growth. Odors associated with hidden water damage do not go away and tend to be stronger in the area of the damage.
2. Water Spots And Stains
As water leaks behind drywall, or seeps into walls and ceilings, it will leave behind discolored water spots. These water spots may also grow larger over time as the water spreads.
3. Ruined Walls And Paint
Bubbling and peeling paint on walls is a result of water and moisture build up behind the wall. The excess moisture will end up pushing its way through the wall, ruining the bond in paint and causing it to separate from the wall.
4. Structural Changes
Changes to walls, ceilings and floors should not be taken lightly. They will begin to swell and cause ceilings to sag and crack, walls to bow and buckle, and floors to warp and feel spongy.
5. Mold
Mold grows and spreads through microscopic spores that can adhere to many different surfaces in your home. Mold can have different appearances and colors; it often appears fuzzy and has different shades of green, brown, black and even white.
