Attic Mold Removal


Most homeowners do not usually suspect they have mold in their attic until a home inspector discovers it.  Attic mold is, however, a common occurrence in areas where climate norms include rain and humidity in the summer and snow and ice in the winter.  Though these climate conditions are not the sole cause of attic mold, they can contribute when combined with other aggravating factors.

If you have a mold problem in your attic or would like a mold inspection done to see if you have visible mold, Certified Indoor Environmental can help. We are a residential and commercial mold removal and remediation company that serves Oregon’s Portland and Salem metropolitan areas. We work with homeowners, realtors, home inspectors, home sellers, home buyers, property managers, and anyone who needs mold testing or mold remediation performed.

Our family-owned and operated company is well familiar with the damp climate of the Pacific Northwest, and experts specializing in attic mold remediation. Our customers consistently give us a 5 star customer service rating.

Attic mold is directly attributable to four main causes:

  1. Lack of adequate ventilation and/or improper ventilation to eliminate moisture
  2. Roof and/or roof flashing leaks
  3. Improperly exhausted bathroom fans, kitchen fans, and dryer vents
  4. Attic bypasses leaking warm air into the attic or attic air leaks that cannot escape the attic

Mold causes damage to your home’s structural components – wood, drywall, insulation, etc.  Mold also destroys personal belongings stored in the attic, such as books and papers, clothing, photos, and any other type of organic substance. Mold can worsen symptoms in people with allergies and asthma, and be especially dangerous to children and older people.  Mold contamination requires prompt and proper treatment if you want to minimize the damage and restore your home to a safe, healthy condition.

The best way to control mold growth in your attic is to control the moisture that gets in.  For example, in cold weather, moisture condenses on cold surfaces such as attic roof sheathing, or warm air leaks into the attic space from the rooms below, or ice dams build up on the roof and force water inside – all situations that present an optimum environment for mold to grow if the moisture has no way to escape.  Attics should be properly ventilated so that moisture that enters also has a way to get out.  Without ventilation, moisture and dampness have nowhere to go.  As a result, mold spores quickly settle in and thrive in the dark, damp environment.

Our Attic Mold Remediation Process

The experts at Certified Indoor Environmental put into action a proven step-by-step process for removing and cleaning attic mold – a process that obtains the best results possible no matter what the cause.

  1. The first step is to assess the situation and determine the cause of the mold, whether from a lack of proper ventilation, a leaky roof, improper exhaust fan venting, or attic air leaks.
  2. Next, we take steps to protect your home. For example, we lay protective canvas along the walkways of the house that lead to the area where we will be working. We isolate the attic from the rest of the house to prevent the further spread of mold and minimize the disruption to you and your family.
  3. Once the attic space has been isolated, we don protective gear and get to work on remediating the mold. We HEPA vacuum the mold, sand and scrape all visible microbial and apply a stain remover to the attic sheathing.
  4. Job completion includes performing a final walk-through and inspection of our work.
  5. We provide homeowners with a certified mold report that contains photos of the attic area both before and after our work, the mold removal process steps we followed to clean and eliminate the mold, and our recommendations for preventing future infestations.
