A dark spot or stain on the ceiling or walls indicates freshness, while older water damage can develop rings on the wall or ceiling. The more rings there are, the older the water damage is. As the circles change colors, it can indicate whether the water is wet, dry, or has been there for a long time.
You can test for moisture by covering the area with plastic and taping all the way around to seal it. if moisture starts condensating over a few days time in between the plastic and stained surface then you, in all likelihood, have an active leak.
As noted above, water damage will usually leave walls soft to the touch, or otherwise warped, buckled, and crumbled. It also tends to cause a musty smell and dark brown or yellow-tinted stains, lines, or rings in both ceilings and walls.
Physical appearance alone is not enough to differentiate water damage from mold. A musty, pungent, or earthy smell is a more definite sign of mold growth. Water damage does not always mean mold, but signs of water damage may indicate mold growth since mold grows where there is a lot of moisture.
Water stains: A clear sign you have a plumbing issue is water stains. There could be signs of water damage on the ceiling or walls with abstract shapes. The stains often have a yellowish-brown color.
Unlike new water damage, which appears as dark and wet patches, old water damage stains are typically yellowish or brownish. These stains may have been present for a long time, indicating that water damage occurred in the past and was never adequately addressed.
In some cases, water stains on ceilings can be caused by condensation. This is most common in homes with poor ventilation, like those with little or no insulation. If you think this might be the case, it's important to improve the ventilation in your home and address any other moisture problems as soon as possible.
mildew and mold will develop within 24-48 hours of water exposure. Even worse, it will continue to grow until steps are taken to eliminate the source of moisture, and effectively deal with the mold problem.
Older damage generated by water will have rings around it, and just like a tree, the more rings shows the age. Different shades and colors of rings tell you that the area has been soaked, dried, soaked, dried, etc.
Under most standard home insurance policies, if water damage occurs suddenly or accidentally from a source inside your home, such as a busted pipe, it will likely be covered by your homeowners insurance. If the water comes from outside your home, it will not be covered by your standard policy.
if you Prime and paint over the top of water stains, this does not actually solve the problem, and they will reappear. It's important to discover why the water stains have appeared, repair the actual problem, and then complete cosmetic repairs.
Look for visible signs of mold—stains, black spots, or discoloration on walls, floors, or ceilings. Don't forget to check inside your closets, under carpets, and behind furniture. Pay attention to odors. Even if you don't see mold, a musty smell is usually a tell-tale sign it's starting to form.
"If there is a water stain, but the drywall is still hard to the touch and otherwise undamaged, you can move forward with a primer and paint," he explains, noting that your primer choice matters. "You can't just coat over a water stain, because it will bleed through—you must first use a water or oil-based primer."

The cough is typically dry and non-productive, meaning it doesn't bring up mucus. It is sometimes described as having a "barking" or "hacking" sound.
If you have an area in your home that is damp and moist, or has experienced a long-term water leak, then that area is susceptible to mold growth. Unlike the look of water stains, look for areas that are white, blue, green, or black in color. Grout that has darkened is another sign that you might have mold growing.
The only way to prevent mold infestation in drywall following a water damage incident is to dry it within 48 hours after water intrusion. The 48-72 hour window is critical to prevent mold growth as it usually takes 24 to 48 hours for mold to germinate and grow.
