Have you found mold in your attic?

Effective attic mold remediation involves two components: (1) removal of the attic mold and (2) addressing spores in the air and on surfaces within the attic.

Removal of attic mold used to require removal of the affected roof decking.   One of the best alternatives to whole roof replacement is an abrasive cleaning method called dry ice blasting.  This method is not only less labor intensive than sanding or scrubbing, it is more effective because the dry ice freezes the surface of the moldy substrate.  Dry ice blasting also facilitates cleaning of crevices and hard to reach areas.  As with all mold remediation, appropriate containment measures, personal protection, and engineering controls must be employed.

Attic Mold Removal

Attic mold can hold up the sale of a home.

Homeowners don’t usually notice it until it’s pointed out by a building inspector. And they don’t call an inspector until they’re getting ready to sell or buy a home. This leads to costly delays.

In 90% of moldy attics, the sheathing (boards or plywood covering the roof framing) will be black (possibly with the infamous ‘black mold‘). If you can see attic mold then removal is necessary.

Eliminate the causes, eliminate the mold.

The major source of mold in attics is improper ventilation:

• Soffits (overhangs) aren’t ventilated or they’re blocked by insulation.
• No gable vents (at the inverted “v” of the roof).
• No ridge vent (going the length of the roof at the top).
• A bathroom’s exhaust venting into the attic. Moisture escaping the bathroom hits the sheathing, and cold air outside creates condensation inside, creating mold-optimal conditions.

The other major cause is water, such as from:

• Leaks in the roof
• Chimneys with improper flashing (material used to prevent leakage).

These issues, coupled with other mold-friendly conditions, creates attic mold problems and must be corrected.

The Attic Mold Removal Process: Phase I (Abatement)

First, the ventilation and water issues must be addressed. There’s no sense in removing the mold until you remove the conditions that let it grow. When you eliminate the cause, only then can you eliminate the mildew and mold.  In some cases the ventilation and water issues cannot be addressed until the attic mold has been remediated.

The attic mold removal and abatement process includes correcting any ventilation defects, and removing and replacing insulation. It is not usually necessary to replace sheathing.

Attic Remediation Process: Phase II (Removal)

We use a multi-step process for attic mold treatment that includes but is not limited to the following:

1. Contain any materials not
   receiving treatment with 6 mil. poly plastic .
2. HEPA vac all surfaces
   recieving treatment.
3. Remove Insulation.
4. Dry Ice Blast all areas of visible mold growth.
5. Apply an antimicrobial product throughout (preventing mold from regrowing).
6. Supply negative air (for all
   jobs) to keep any contamination from spreading.

All our mold remediation products are environmentally friendly, and very green!
