Building Type: Residential Home
Primary Complaint: Attic Mold
Project Number: 104051
Relevant Project Info:
Mold Growth:
- Inspection of attic revealed mild to moderate amounts of 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 may be a health concern and is an indication of a failure of the home to adequately exhaust damp air created by the occupants.
Moisture:
- At the time of inspection no increased moisture content was noted in the framing or sheathing, but the mold growth suggests that moisture content is likely increased at specific times of the year.
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:
- Insufficient soffit ventilation throughout the attic. Existing ventilation blocked by improperly installed insulation. This limits the influx of fresh air through the soffit vents, leading to excess condensation and mold growth. It is recommended that blocked soffit vents be cleared and all soffit venting be protected by the appropriate baffling.
- 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.
Air Seal:
- The ceiling currently lacks proper air sealing, allowing excess moisture and heat to escape into the attic area. This air leakage is a key cause of energy loss, attic condensation and mold growth.
Ducting:
- No exhaust ducting exists.
Other Contamination:
- No evidence of past or present rodent infestation was noted,
Trash and debris:
- The attic is currently free from excessive amounts of trash and construction debris.
