Mold growth is a sign that the leak is relatively new. Fresh mold develops within two days of new water damage. You may get mildew if you see white or black spots on a surface that look like dust, cotton, or velvet. You can tell if the mold is old or new by studying its appearance.
Active (new) mold has visible filaments that make it look bushy. These filaments can adhere to the surface and make it difficult to clean. Inactive or old mold is dry and dusty and can be easily removed from the wall with a brush. Mold is a dangerous substance, so be careful not to inhale it.
Call a professional who specializes in mold damage immediately for an evaluation. Sensing the place that has suffered water damage is a good way to find out if the damage occurred recently or if it has been there for a long time. Freshwater damage will get wet, but the material will remain firm and not soft. Damage caused by old water will create a soft, soft stain due to the time the material has had to absorb moisture.
The type of materials exposed determines the period of time during which water-damaged stains are identified. Knowing this, if you find mold growing in your home or building, there is a good chance that water damage has occurred somewhere. The chances of water damage increase significantly after a heavy rain or part of your home is not functioning properly. Water damage is known to be the most common form of property damage due to the numerous ways in which it can occur.
Therefore, finding out if a material has been damaged by fresh or old water can give you an idea of the magnitude of the damage, as well as the urgency of restoring the damage. If the wood or drywall feels soft, it means that the water has had time to fully penetrate the material, so the initial leak or incident most likely occurred a few days earlier. There are methods to estimate when the water damage occurred, as well as to identify the source of the problem if it is new. You can use these tips on how to know if water damage is new or old to get important information.
Rings most often occur in places where water leakage is occasional, such as a spot under a roof leak that only gets wet when it rains. Natural phenomena, such as storms and floods, can easily cause water damage, but there are also internal problems, such as pipe breaks and wastewater accumulations, that can allow excess water to enter a residential or commercial property and, in the process, damage it. If mold has spread beyond where water damage is directly visible, it may indicate damage caused by water that has been accumulating over a longer period of time. If you see mold, damp spots, or water stains on hard material, you're most likely seeing signs of damage caused by old or existing water.
The last signal you can use to estimate the length is to touch the point damaged by water. Soft building materials will form rings if the water has suffered repeated damage over an extended period of time.
