Client has noticed mold growth on ceilings and walls in several rooms and is concerned with the source of mold and resulting air quality. Environix hired to inspect the areas of concern and provide a bid for remediation.
Property is a church.
CAUSE OF MOLD:
Previous roof leak and condensation on cold walls.
ANALYSIS OF YOUR RESULTS:
Moderate Amplification: Mold spores were detected at levels above the threshold, indicating a site of probable mold amplification and growth. Please refer to the attached report for more detailed information.
The most likely contributor of the elevated mold spores is:
Recent water intrusion.
Although the indoor mold spore levels are only moderately elevated, the on-site examination of the property revealed significant mold problems that require action. Please see included pricing.
Air sample collected in back storage room
Mold growth observed on ceiling
Mold growth observed on walls likely from previous roof leak
Walls are not wet
Roof leak traveled down wall and affected framing at bottom
Roof leak ran down gable wall to rooms below, mold observed on gable wall in attic
Mold affected walls need removal to treat wall cavities for mold growth.
OBSERVATIONS APPLICABLE TO ENTIRE INSPECTION AREA:
A roof leak was discovered recently, and repaired approximately 3 weeks prior to the inspection date.
Mold was observed in the building. Some of the mold is the result of the roof leak, and some of the mold is the result of condensation in the building from insufficient ventilation, insulation, and heat.
A small amount of mold was found in the attic. This mold is not significant enough to warrant professional remediation.
LOCATIONS: Back Storage Room, Room 1, Room 2, & Hall
A recent roof leak came down the gable side of the attic, and affected the walls in the rooms below. These walls need removal to treat mold growth.
Moderate mold growth observed on ceiling drywall in all locations listed above. The drywall was inspected from above within the attic, and did not appear to be severely damaged from that side. This drywall will not require removal.
Missing or low insulation was noted above all of these affected areas. This is likely contributing to condensation and mold growth on these surfaces, as the cool ceiling temperature will encourage warm humid air to condense here and result in condensation-based mold growth.
The walls in the back storage room, room 1, and the hall will require drywall removal to treat mold growth within the wall cavity. The leak came from above, so the drywall needs to be removed from ceiling to floor in these rooms.
Professional mold remediation is necessary to properly address the existing mold growth and to prevent cross contamination. During remediation, HEPA filtration, negative air pressurization and proper personal protective equipment must be utilized. Please see included pricing.
Recommend adding insulation in the attic to stop the cold ceiling issue.
The areas with visible mold growth should not be occupied until the mold remediation project is complete.
