What Are The Signs Of Mold
Mold starts out as a little spot but expands quickly. Youll usually notice it early on, unless its in an out-of-the-way location.
Mold can be black, white, spotted, or just about any color, and may appear powdery, cottony, or velvety.
If you notice a spot and arent sure if its just an old stain or a splotch of dirt, heres how to tell if it could be a sign of mold:
- It has a musty, earthy smell.
- Theres a nearby source of moisture, but not much light.
- You see warping, cracking, or peeling of whatever material its growing on.
- A drop of bleach lightens its color in a minute or two.
- Unchecked, mold will continue to grow. Dirt and old stains wont.
Having mold in your home wont necessarily make you sick. But it does have the potential to cause certain health issues.
Touching or inhaling mold spores can cause allergy-type symptoms such as:
- runny nose and congestion
- lung irritation
- wheezing
In many cases, you can get rid of household mold yourself. Mold can be removed with:
- commercial products
- a bleach solution of 8 ounces of bleach per 1 gallon of water
Before you begin:
- Wear protective eyewear, nonporous gloves, and a face mask or N-95 respirator.
- Never mix other cleaners or ammonia with bleach, as it can create toxic fumes.
Use a brush to scrub mold off surfaces, making sure you get it all. Porous materials, such as carpeting, furniture, and ceiling tiles, may have to be discarded. Dont paint or caulk until youre sure all the mold is gone.
The Problem With Petri Dishes
When you notice or suspect mold somewhere in your home it isnt uncommon to want to test your home and get some concrete answers or proof about what is happening. This feeling is completely understandable as mold in your home can be a cause for concern, especially if someone in the home is experiencing health symptoms that may be related.
Often the most accessible and affordable option is a DIY mold test kit available online or in most hardware stores where you can get results in about 48 hours.
However, the DIY mold test kit option comes with more than a few drawbacks including no accredited lab certification or chain of custody for legal verification, inconsistent lab results from location choice, expired collection plates, and uncontrolled shipping/handling.
But the biggest issue is that it cant answer your most important questions is the mold I have a problem and where is it located?
Petri dishes are designed to grow mold spores and since there are mold spores in the air everywhere all the time, you should expect to get mold spores growing on the plates. But since plates can only capture a limited group of spores , most spores will go undetected. You wont get enough of the whole story to be able to determine if the sample is or isnt representative of what is going on in your home.
So what does growth on the plates actually mean? It means you have mold spores in your air. Which almost everyone does.
What else your plate or mold test kit wont tell you:

Testing For Hidden Or Airborne Mold
Air Quality Testing For Mold
Most people are not aware of how severely mold can affect their health. Because mold spores are so small, they can become airborne easily and spread quickly. Just because you cannot see a mold contamination in your home doesnt mean that its not there.
Mold and mildew are the result of moisture and water damage. Rooms that are prone to leaks, condensation and flooding often experience mold growth. These include bathrooms, attics and basements.
Property owners have to be careful because moisture problems are not always obvious or visible. They can remain completely hidden from sight . If left untreated, they will lead to black mold contamination.
Exposure to black mold can cause or aggravate health conditions like asthma and allergies.
Over time, it can also lead to more serious conditions such as chronic bronchitis, problems with the nervous system, cancer and heart conditions.
Luckily, you have two types of air tests to help you detect unseen mold: viable sampling and non-viable sampling. Each has its advantages and drawbacks , but both are effective means of assessing indoor air quality.

Health Symptoms That Can Be Caused By Mold In Your House
Mold doesnt bother everyone. In fact, out of thousands of mold species, only a few dozen will trigger any health problems at all, according to the Asthma and Allergy Foundation of America. Still, some of us are sensitive to molds. People who are allergic to an indoor mold can experience year-round symptoms like a sore throat, cough, stuffy nose, and more for those who also have asthma, mold can trigger an asthma attack. People with a weakened immune system or a chronic lung condition like chronic obstructive pulmonary disease can develop a serious infection in the lungs if theyre exposed to mold.
People without allergies and asthma arent immune to the effects: In 2004, the Institute of Medicine concluded that people without pre-existing lung conditions can also experience symptoms like nasal congestion and a sore throat if they live in a house with damp floors or moisture accumulation.

Getting A Mold Checkup
Getting rid of the mold in your home is your first priority. Since CDC guidelines don’t distinguish between different types of mold and recommend the prompt removal of all mold in your home, testing beforehand isn’t a priority if you’ve already decided you have a problem. Testing can be useful when you want to make sure your property is free of mold after a cleanup, though.
There are a couple of ways you can arrange for a test. You can purchase an in-home test kit, follow the directions and submit the resulting sample to a lab. The costs for this can vary quite a bit, anywhere from $40 to more than $200, and the results might not be reliable. Consumer Reports conducted an evaluation of home mold testing kits in 2006, and none of the four kits they looked at received a recommendation. The problems ranged from the kits having no expiration dates, potentially compromising the results, to being difficult to use .
There is a third choice. After a cleanup, you can make periodic, careful evaluations of the infected area yourself and monitor your family’s health to see if the problem recurs. The time and effort you take with the clean-up and the extent of the mold damage may have an impact on how comfortable you feel with this option. If a foul smell alerted you to a mold problem in the first place, using your nose to check the area periodically might be a good way to gauge the success of your cleanup efforts.
How Do Doctors Diagnose Mold Allergy
To diagnose an allergy to mold or fungi, the doctor will take a complete medical history. If they suspect a mold allergy, the doctor often will do skin tests or allergen specific IgE blood tests. Extracts of different types of fungi may be used to scratch or prick the skin. If there is no reaction, then you probably dont have an allergy. The doctor uses the patient’s medical history, the skin testing results and the physical exam to diagnose a mold allergy.

- Empty and clean refrigerator drip pans if necessary.

- Avoid leaving damp clothes in the laundry basket or dryer. Wash and dry them promptly.

In this case, assessment by a qualified professional is recommended but in most cases a medium amount of mould may be cleaned up using proper procedures and protective equipment .
An area of mould is considered large if a single patch of mould is larger than three square metres. Health Canada does not recommend that an unqualified person clean up large areas of mould. You may need a professional assessment to determine why the mould is there in the first place and how to clean it up.
Can You Get Sick From Mold In Your House
