Signs of mold can mean you need a mold inspection.
If mold is hidden then you will only find out about it by noticing mold signs. By noticing mold signs you can find mold early. This can save you a lot of money and a lot of trouble, since you can stop mold before it becomes a much bigger problem.
MOLD IN HOMES HAVE BEEN ASSOCIATED WITH THE FOLLOWING HEALTH RELATED SYMPTOMS
Asthma like reaction
Runny or Blocked Nose
Often people do not realize these symptoms are caused by mold in the home. Instead they think they have a cold or something else causing these symptoms.
One sign that these symptoms are from mold is that the symptoms decrease when you leave your home. Another sign is that multiple people in your home suffer these symptoms. Some molds such as black toxic mold (Stachybotrys)can also cause toxic symptoms. These are only suggestions based on research produced by health care providers. ” Please do not take these as health related advice ,“Contact your healthcare provider”
SIGNS YOU MAY HAVE MOLD IN YOUR HOME
Another sign of hidden mold is a moldy smell. If the smell is worse in certain rooms then the mold is probably growing near that area. If the mold smell gets worse when the air conditioning or heating is on then there could be a mold problem in the HVAC, or in your air conditioner or heater.
Sometimes people see mold without realizing. You might have to look closely to identify mold. People often have mold growing in their bathroom, on the grout between tiles. However they do not realize it is mold.
People also might ignore small amounts of mold, even though they can see it. However small amounts of mold means there is enough moisture for mold to grow. It can mean there is more mold in the home.
For example, mold hidden behind a wall eventually grows through. This leads to small spots of mold on the inside wall.
Another potential mold sign is humidity. High humidity can lead to condensation and water accumulation. Things also take longer to dry out when the air is humid. Some molds can live off humidity in the air.
A humidity level above 60% can lead to mold growth. It’s best to keep humidity between 30% and 60%. You can buy humidity monitors to keep an eye on the humidity in your home.
If you live near water, such as the coast or a lake, the humidity may be high. Using air conditioning and HVAC can also change the humidity levels indoors.
Condensation may create moisture problems, because the water from condensation can build up. Condensation is also a sign of humidity.
Condensation often occurs on cold surfaces, such as windows and metal pipes. This is because when water vapour in the air touches a cold surface, it cools and becomes liquid.
If you often see condensation, it could be a sign of a moisture problem, and perhaps a mold problem.
Water leaks can be a sign of mold. Leaks in pipes and roofs are the most common. Cracks in walls can also let in moisture. Leaking taps can also create moisture problems.
Leaks are often hidden (for example inside wall cavities or in the attic). If a leak is undetected for a long time, it is very likely to cause mold. If you discover a leak then you should check for mold.
Leaking Roof or Attic
Signs of a leaking roof are water damage on the ceiling below the attic. There will also be signs of water damage in the attic.
Cracks and splits in the roof are another sign. Beams that have gotten moisture in them become weakened. This can lead to the roof sagging.
Another sign you could have mold is if your house has been flooded in the past. Flooding that left materials, like drywall, wet for more than 24 hours probably caused mold.
Past flooding can be a sign you have hidden mold (eg inside wall cavities). It can also be a sign of mold problems in the basement.
The basement is one room which usually doesn’t get much ventilation. It is usually cold too, which can lead to condensation. Water can end up running down into the basement, also. If it floods, the basement is usually the worst affected room. If you notice your basement is often damp, this could be a sign of a mold problem.
Another sign of a water problem is water stains on walls, ceilings and other surfaces. Often stains will be yellowish. If there is mold growing the stain might be darker.
Ceiling leaks often cause water stains in the walls and ceiling. Stains around windows can also be a sign of water intrusion.
When there is a lot of moisture, paint may start to come off surfaces. Paint, or wallpaper, may be peeling, cracked, bulging or bubbling, if moisture is building up behind it.
Rust in the home is a sign of a moisture problem. You might see rust on nails or metal pipes. This could mean you have high humidity, condensation, a water leak, or some other water problem.
When moisture gets into wood, drywall and other materials it can cause bowing. If you see warped walls, or other surfaces, you probably have a moisture problem.
Water problems can deteriorate materials in your home. Seeing building materials which have deteriorated from moisture can be another sign of mold.
When it rains, you may see water building up on the ground near your house. This is usually caused by blocked gutters, or ground sloping towards your house.
It can be a sign of indoor moisture problems, because the water can seep into the walls or the foundation. Blocked gutters can also cause water to run down into the roof, or down the walls.
Look out for rooms with poor air flow. This can be a sign of moisture problems. Ventilation helps to dry out moisture. A lack of ventilation allows moisture to remain much longer.
You might often see water building up, or pools of water around your home. This can lead to mold problems. Sometimes you might be able to see moisture on walls and other surfaces too.
There is often a lot of standing water in the bathroom or kitchen. Steam in these rooms can also create problems.
History of Water Problems
A history of water problems can also be a sign of mold. If your home has previously been flooded, or has had water leaks, then you could have mold.
A dirty or dusty home is more likely to have mold. Mold grows on dust. Dust can also transport mold spores around the home.
