Recent Attic Mold Remediation Example
Work #: 202034
Project Information
Mold Growth:
- Inspection of attic revealed moderate mold growth throughout significant areas of attic sheathing. At this time, the mold growth has not lead to significant structural damage of the underlying materials. However, the mold growth is an indication of a failure of the home to adequately exhaust damp air created by the occupants.
Moisture:
- Elevated moisture noted throughout select portions of the attic sheathing. It is necessary to allow the the framing and sheathing to dry prior to the application of encapsulant.
Leaks:
- No obvious roof leaks were observed on inspection of the attic. Environix is not a professional roofing contractor and cannot guarantee the condition of any roofing structure.
Insulation:
- Insulation shows no signs of significant water damage, or mold growth. Spores may be present in the insulation, and it can be removed at the customer’s request, but once the recommended steps are performed the spores are unlikely to negatively impact indoor air quality.
Ventilation:
- Current ventilation is adequate to exhaust normal amounts of humidity.
- Insufficient ridge area ventilation installed throughout attic. This limits the exhaustion of humid air through the roof assembly. 3 additional 50 square inch passive vents will need to be added in an evenly spaced manner.
Insufficient soffit ventilation throughout the attic. No soffit ventilation currently installed. At least 2.75 SF net free area of evenly spaced soffit venting will need to be added. - Proper ventilation is necessary to minimize condensation and subsequent mold growth. All areas of elevated moisture or improper ventilation must be addressed to ensure the effectiveness of our process. Current code calls for 1sqft of ventilation for every 300 square feet of attic space, distributed evenly between the ridge and soffit area.
- Gable vent is currently installed and must be blocked to prevent the short-circuiting of the needed convective currents.
