Mold infestation in your attic can be dangerous to your health and can impact the structural integrity of buildings for residents in Victoria, Cowichan, Duncan, Nanaimo, Parksville, Qualicum, Courtenay, Comox, Campbell River, and Port Alberni.

Here are a few factors that have a major impact on making attic area a “mold friendly” environment:

 #1 cause of mold growth in the attic – inadequate attic ventilation

bathroom / kitchen / dryer vents discharging into the attic

inadequate / missing attic floor insulation

improperly insulated cathedral ceilings and skylight chases

furnaces and water heaters installed in open attic

plumbing vents open into the attic – uninsulated air ducts

poorly insulated ceiling penetrations, attic access panels

Just inadequate ventilation and dryer vents combined together could transform your attic into the steamy, mold contaminated room during the cold wet seasons we experience here on Vancouver Island and west coast towns like Port Alberni, Tofino and Ucluelet.

Any warm air trapped under the roof will form condensation on framing, decking surfaces, and roofing nails creating mold nesting habitat. Some homes have more than one attic and upper one, usually located above the bedrooms and bathrooms is always more susceptible of being contaminated, because warm air from lower parts of the house will naturally raise up, transfer through the ceiling and all its penetrations into the attic.

Mold Exposure – How Vulnerable Are You?

Inhaling or touching mold or mildew may have hazardous health effects. But, not everyone may be adversely affected by molds. Those who have other allergies or existing respiratory conditions such as asthma, sinusitis, or other lung diseases are more susceptible to the effects of mold exposure.

People with an impaired or weakened immune system will have severe reactions to molds. Pregnancy, autoimmune disease, AIDS, or diabetes are medical conditions that can weaken your immune system. Infants, small children, and elderly people are also vulnerable to mold contamination.  Read more.
