Mold & Dust Mite Health Facts

  1. Dust Mites & Mold Eat Organic Materials: That means any organic material at all. Dust, fabric, fiberglass resins and dyes, drywall, wallpaper, glue, paint, wood, or anything else is enough to keep it growing. As for dust mites, 1,000 of these critters can live in a single gram of dust, each one creating 20 waste pellets per day.
  2. Mold Can Live In The Cold: Ever see mold in a refrigerator? Research shows that as long as the temperature is above 40 °F (4 °C), mold can grow and spread.
  3. Mold & Dust Mites Grow Fast: Mold can begin to grow in a home in as little as 24-48 hours, with a billion mold spores growing on a single foot of drywall. A single female dust mite can lay upwards of 250 eggs in its three-month life span.
  4. Mold Leads To Insurance Woes: Due to tens of thousands of mold-related lawsuits being filed, most general liability and property insurance companies now exclude mold insurance from their policies.
  5. Mold Destroys Your Home: Professional Builder Magazine warns that mold will dramatically lower the value of your home. A home worth $250,000 can have $100,000 in mold problems. Mold can even lead to structural damage to your home!
  6. Mold Spores Can Damage Your Health: Mold spore exposure can occur through inhalation, ingestion, and skin contact. Mold and dust mite waste is connected to allergies, asthma, and other breathing issues. Even dead mold spores can be damaging to your health.
  7. Dust Mite Waste Is Highly Allergenic: 90% of patients show dermal reactivity to dust mite waste and 10% of the general population is also sensitive. Dust mite waste makes up 80-90% of the allergic component of house dust, containing 15 potent allergens that sensitize and trigger allergic reactions. In fact, American Family Physician states that "controlling dust mites is the most important thing you can do in your house to make your asthma and allergies better."
  8. Mold & Dust Mites Are Sneaky: Mold can grow in fiberglass insulation, behind drywall panels, and behind wallpaper. Dust mites can live in furniture, cloth, and pillows. Just because you don't see a problem does not mean that one does not exist.

To Sum It Up: As Glenn Fellman, executive director of the Indoor Air Quality Association states, "If you are reacting to a problem because somebody's been sick, you've waited way too long to address indoor air quality." The best way to protect yourself is to prevent the mold or dust mite problem before it begins!

A waterproofed basement that has been finished into a family room in Medford

Remodeling a basement is not the same as remodeling elsewhere in your home. Humidity makes its way straight through your concrete walls and into your home. If that humidity meets paint, drywall, fiberglass, wood, or other products with organic material, you can expect mold to grow there. And with a basement, it's just a matter of time before a plumbing or groundwater leak occurs.

When finishing a basement, use inorganic materials and a vapor barrier to protect your investment from water and mold damage.

Stack Effect Causes Mold & Moisture in Your Crawl Space

When hot air leaves the house through the attic and upper levels of your home, this creates a vacuum, which pulls air from the basement, crawl space and other lower levels of your home.

This phenomenon is called the stack effect and it is responsible for common problems related to moisture in your home, including mold and dry rot damage.

In order to prevent moisture damage in your crawl space and other parts of your home, it's important to seal the crawl space and install a vapor barrier and other moisture-control solutions in order to prevent further damage to your home.

Professional Solutions for Mold, Rot & Dust Mites Problems

Mold, rot and dust mites all have a common weakness: they all need ample moisture and humidity to survive.

Both mold and dust mites need moisture from the air to survive. When humidity levels drop below 60% they will not be able to thrive.

By sealing out humidity from outside air and installing a dehumidifier, you can protect yourself from mold and dust mite problems.

Common Home Mold

Mold spores are present nearly everywhere, growing when they meet sufficient temperature, moisture, and organic material to grow.

50% of homes have at least one resident with allergies, with The American Lung Association showing that 88 million Americans suffering from some sort of respiratory distress. 90% of people with allergies show sensitivity to mold spores.

Dust Mites

Dust mites are microscopic arachnids that live in your home, most often in carpeting, sofas, pillows, and other cushioned furniture.

Dust mites create allergenic fecal material, which they release into the air as much as 20 times a day. Dust mites live in humid areas, absorbing moisture directly from the air.

Black Mold

Black Mold is a highly toxic mold that is rare but dangerous when it grows in the home.

Black mold spores host a fungus that produces carcinogenic "mycotoxins" that are linked to ailments such as liver cancer, lung cancer, chronic liver damage, acute or chronic nervous system damage, endocrine problems, and others.

Rot and Decay

Mold and rot can begin to form in damp wood in as little as 24-48 hours.

If allowed to damage wood unchecked, rot, mold, and dry rot can lead to many thousands of dollars worth of damage to a home. In the case of dry rot, a 75% loss of toughness can be caused by a 1% weight loss. Rot and mold in wood should be addressed as soon as possible.
