Mold Inspection Reports from Everett

Below are recent mold inspection projects we’ve completed in the Everett area.  These reports can help provide you with an idea of the issues we typically encounter in your region.

Project Type > Mold Inspection and Remediation Project in Everett

PROJECT SUMMARY

REASON FOR INSPECTION:

  • Client found mushrooms growing from behind the stove. He requested an inspection to determine the source of the problem.

PROPERTY DESCRIPTION:

  • This single family residential property was built in 2007 and is 2,589 ft².

CAUSE OF MOLD:

  • Previous leak from the fridge provided the moisture for the mold and fungal growth. Leak appears to have been properly addressed.

RELATIVE HUMIDITY & CO2 READINGS:

Pic1

VENTILATION:

  • Relative humidity levels are normal. Generally, indoor RH levels should remain under 55% or under 50% in homes with poorly insulated exterior walls.
  • CO2 levels are near the threshold. While not a direct health problem, elevated CO2 levels are an indication of stale indoor air and poor ventilation. This can lead to a buildup of pollutants and humidity, which can cause mold growth. Following the ventilation recommendations listed below will lower the CO2 levels in the home.

LOCATION: Kitchen

Observations:

  • An old leak from the prior refrigerator has resulted in water damage to the cabinet between the stove and fridge. The leak is no longer an issue.
  • Mold growth observed on the floor under the cabinet between the stove and fridge.

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 included pricing.

Project Type > Full Home Inspection for Mold in Everett

PROJECT SUMMARY

REASON FOR INSPECTION:

  • Client has been experiencing health related issues when in her bedroom. They are concerned with mold and air quality issues.

PROPERTY DESCRIPTION:

  • This single family residential property was built in 1948 and is 1,897 ft².

CAUSE OF MOLD:

  • Elevated humidity causing condensation and mold on surfaces.

LABORATORY RESULTS

ANALYSIS OF YOUR RESULTS:

  • Minor Amplification: Mold spores were detected at or near the threshold. This indicates a possible site of mold amplification. Further testing and/or comparison with the results of a visual inspection are necessary to determine the likelihood of indoor amplification.

The most likely contributor of the elevated mold spores is:

  • Elevated humidity.

Recommendations:

  • Although your indoor mold spore count is elevated, the levels are not high enough to warrant professional remediation. By following the recommendations listed in the report and implementing regular cleaning, the mold spore levels should return to normal.

RELATIVE HUMIDITY & CO2 READINGS:

Pic1

VENTILATION:

OBSERVATIONS:

  • Relative humidity levels are elevated. Generally, indoor RH levels should remain under 55% or under 50% in homes with poorly insulated exterior walls.
  • CO2 levels are elevated. While not a direct health problem, elevated CO2 levels are an indication of stale indoor air and poor ventilation. This can lead to a buildup of pollutants and humidity, which can cause mold growth. Following the ventilation recommendations listed below will lower the CO2 levels in the home.
  • Home may have been inadequately heated in winter months. A minimum indoor temp of 65ºF must be maintained in the winter months to minimize excessive humidity and mold growth.
  • Home suffers from insufficient ventilation. This leads to a buildup of indoor pollutants and increases the relative humidity, creating conditions conducive to mold growth and dust mites.

LOCATION: Hall Bathroom

OBSERVATIONS:

  • The bathroom fan has been removed from the ceiling. This has resulted in a humid environment and creates conditions conducive to mold growth.
  • The bathroom windows have been updated to double paned vinyl framed.
  • The bathroom has been painted with a matte paint. This absorbs moisture and contributes to an environment conducive to mold growth.

CEILING:

  • Moderate mold growth noted on bathroom ceiling. This occurs when the warm, moist air generated by shower usage interacts with the cool surface of the ceiling. Without adequate ventilation, this causes condensation and subsequent mold growth.

Recommendations:

  • See ventilation section above for recommendations to eliminate condensation. Installing a bathroom ventilation fan that has exhaust ducted to the exterior of the home is critical.

LOCATION: Mom’s Bedroom

OBSERVATIONS:

  • A faint odor of incense was present at time of inspection.
  • Client notes an “earthy” odor often present in this room. This may be the result of the prior incense use, or from the ongoing high relative humidity in the home. Elevated humidity can amplify odors, mold spores, and allergens which can trigger asthmatic response. The client notes that she has asthma.
  • The hatch to the crawlspace is in this room. This could be allowing odors from the crawlspace to accumulate in this room.

LOCATION: Crawlspace

OBSERVATIONS:

  • Vapor barrier missing. Exposed areas of soil in the crawlspace allow significant quantities of water vapor to migrate upward into the home, increasing the relative humidity. Additionally, exposed areas of soil often allow odors to move upward into the home. The lack of vapor barrier in the crawlspace could be contributing to the “earthy” odor the client has described.

Recommendations:

  • First implement the ventilation revisions described above. If the odor problem persists after addressing the ventilation, then contact a crawlspace service company to install a vapor barrier in the crawlspace.
  • Consider improving the air sealing around the crawlspace hatch to reduce air movement into the bedroom above.
