How does mold develop?
Mold requires nutrients, water, oxygen and favorable temperatures in order to grow. Organic materials such as wood, paper or fabrics are a good source of nutrients for mold, making drywall, carpet and wallpaper highly susceptible to mold infestation. Some synthetic products such as paints and adhesives can also serve as food for mold. Once mold spores are brought into a building, the right combination of moisture, darkness and temperature will enable it to grow and spread.
Are there harmful and non-harmful molds?
There are many types of mold. About 100 types are known to cause infection in healthy people, while other molds cause infections only in persons with compromised immune systems. Most people tolerate exposure to moderate levels of many different molds without any apparent adverse health effects, while others may have severe allergic reactions to even the slightest amounts.
Some molds produce powerful chemicals called "mycotoxins" that can cause illness in both animals and people. Scientific knowledge about the health effects of these toxins is quite limited.
What is Mold Remediation?
Mold Remediation is the process of isolating, removing and/or cleaning materials contaminated by a fungal organism. This may be as simple as removing a small section of moldy sheetrock or completely remodeling an entire basement. Also critical to the role of a remediation contractor is to identify and remedy the source of moisture intrusion. Sometimes this will involve subcontracting work to plumbers, roofers, foundation specialists, or other home improvement specialists.
Can mold become a problem in my home?
Yes, if there is moisture available to allow mold to thrive and multiply. The following are sources of indoor moisture that may cause problems:
- Flooding
- Backed-up or clogged sewers
- Leaky roofs
- Humidifiers
- Pipe Leaks
- Water Heater failure
- Damp basement or crawl spaces
- Constant plumbing leaks
- House plants - watering can generate large amounts of moisture
- Steam from cooking
- Shower/bath steam and leaks
- Wet clothes on indoor drying lines
- Clothes dryers vented indoors
- Exhaust from stoves and other appliances not vented outdoor
What are common symptoms of mold exposure?
Exposure to mold spores can cause allergic reactions that vary from person to person. Symptoms are similar to other allergies and can include difficulty breathing, nose and throat irritation, burning eyes, sinus congestion, headaches and fever.
