Tacoma Black Mold Inspection Reports

Project Type > Black Mold Inspection for Several Rooms in Tacoma

PROJECT SUMMARY

REASON FOR INSPECTION:

• Client is purchasing home and was made aware of some mold issues by a home inspector. Environix hired to insect the areas of concern and provide a bid for remediation.

PROPERTY DESCRIPTION:

• This single family 2 story residential property was built in 1919 and is 4,347 ft².

LABORATORY RESULTS

ANALYSIS OF YOUR RESULTS:

• Extreme Amplification: Mold spores were detected at levels many times greater than the threshold, indicating a site of high mold amplification and growth. Please refer to the attached report for more detailed information.

The most likely contributor of the elevated mold spores is:

• Elevated humidity.
• Recent water intrusion.

Recommendations:

• Due to the elevated levels of mold spores, the operation of a commercial HEPA air scrubber is highly recommended. This will rapidly lower the indoor mold spore levels. Please see included pricing.

RELATIVE HUMIDITY, CO2, & TEMPERATURE READINGS:

LOCATION: Basement Living Room

GENERAL OBSERVATIONS:

• An Indoor Air Quality sample was collected in this room.
• Visible mold growth and dark water staining observed on the ceiling against the exterior wall. The home has been vacant for a while, making identification of the leak source difficult. The leak is assumed to either have been from the garbage disposal in the kitchen above, or possibly from drainage of rain water on the back deck traveling along the floor joint to the exterior wall. Without opening the wall for the inspection, the identification of the leak source was not able to be confirmed.
• The exterior wall has wood paneling, limiting its inspection. Mold is assumed to be present behind the wood paneling, which will require removal.
• Slightly elevated moisture detected on the ceiling close to the wall joint in the basement living room. The drywall in this area will require removal.

Recommendations:

• 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 attached pricing.

LOCATION: Basement Bathroom

OBSERVATIONS:

• Visible mold growth observed on the exterior wall and the ceiling of the bathroom. This mold growth is due to the same cause that affected the neighboring basement living room. This mold growth is not the result of condensation; it is the result of a leak from above.

Recommendations:

• The damaged walls and ceiling require professional removal.

LOCATION: Room 3

OBSERVATIONS:

• Visible mold growth observed on the bottom of the drywall on an interior wall in this room. This is likely the result of a water intrusion from a rainwater flood, from the failure of a sump pump or similar issue. This issue looks to be old and is dry.

Recommendations:

• Removal of the bottom 2’ of this wall is necessary.

LOCATION: Kitchen

OBSERVATIONS:

• The dishwasher was pulled out to inspect the cavity behind it. No evidence of water leaks was found on the subfloor below the dishwasher. No visible mold growth or elevated moisture was detected behind the dishwasher. This is not the source of the water leak that has affected the rooms below.
• The cabinet floor under the kitchen sink has evidence of water damage present. The materials currently have no elevated moisture, and this is assumed to be from an old issue.

Recommendations:

• Have a qualified plumbing contractor review the kitchen plumbing to ensure no leaks exist in this area.
• Replace the cabinet floor.

LOCATION: Master Bedroom Closet – Upstairs

OBSERVATIONS:

• Condensation-based mold growth observed on the closet wall within the Master Bedroom. This is often due to limited air flow and insufficient heat.

Recommendations:

• Keep contents and furniture a minimum of 2-3 inches away from exterior walls to help prevent mold growth on these surfaces.
