Mold Inspection Reports from Kent

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

Project Type > Mold Inspection for Bedroom & Bathroom in Kent

PROJECT SUMMARY

REASON FOR INSPECTION:

  • Client’s son is experiencing health issues when he is in the home. They are concerned with mold and air quality problems. Environix hired to inspect the areas of concern as well as collect an indoor air quality sample.

PROPERTY DESCRIPTION:

  • This single family residential property was built in 1957 and is approximately 2000ft².

LABORATORY RESULTS

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:

  • 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. The use of a HEPA grade air scrubber should be used during the cleaning process to remove airborne mold spores.

OBSERVATIONS

ENTIRE INSPECTION AREA:

  • Excessive dust noted in the home. The client notes prior mold issues in the home, and mold spores can settle in dust and on surfaces and continue to affect sensitive people.

Recommendations:

  • Recommend a deep thorough cleaning of the home including the replacement of all carpets. Ensure all surfaces are cleaned with a damp cloth to control dust. The operation of a commercial HEPA scrubber would benefit the indoor air quality significantly, especially while the carpets are being removed. Contact your Environix inspector for HEPA scrubber pricing.

LOCATION: Master Bathroom

OBSERVATIONS:

  • Moderate condensation-based mold growth noted on bathroom windows.

CEILING:

  • Evidence of water stains are present on the ceiling from high relative humidity resulting in condensation on the cool surface of the ceiling.

SHOWER:

  • Grout and caulking is in good condition and shows no signs of recent water intrusion.

LOCATION: Master Bedroom

OBSERVATIONS:

  • Client notes mold was present on exterior wall and on contents placed against the wall.
  • Client noted mold issues when this room was occupied with guests. This is due to elevated humidity caused by occupants. When the humid air comes in contact with a cold surface it will condense and eventually lead to mold growth. There is no current mold growth but the previous mold issues can still affect people fi the room was not thoroughly cleaned.
  • Client noted mold on exterior wall that has since been cleaned off. There was an insulation issue in the past on the exterior wall which was causing this wall to become very cold. This increase condensation and promotes mold growth. The wall has been properly insulated and there are no current condensation issues.
  • Normal temperature differentials noted with IR camera.
  • Relative humidity is currently high in this room even though the temperature is warm. There is a significant amount of warm, humid air in this room that requires additional ventilation.
  • A dehumidifier is being used in this room. It is preferable to use better quality exhaust fans rather than dehumidifiers, to ensure the air is being replaced.

Recommendations:

  • Keep contents and furniture a minimum of 2-3 inches away from exterior walls to help prevent mold growth on these surfaces.
  • The air sample detected a slight elevation of mold in this room and it is likely due to poor ventilation and the previous mold issue. This room should be thoroughly cleaned to remove dust by damp wiping and mopping floors. Soft goods should be machine washed to remove settled mold spores. Once room is clean sensitive individuals can return.

LOCATION: Basement

GENERAL OBSERVATIONS:

  • Client reports white fuzzy mold has growth on exterior and interior walls, book shelves, cupboards, and other furniture. The client has cleaned this mold off with Clorox wipes and vinegar in the past, and the mold returns in the winter months.
  • Only a very small area of a mold was discovered near the basement entrance, by a book case. No other areas of interior mold were identified in the basement.
  • Client reports they do not always heat the basement. The cool temperature of the basement coupled with humid air can result in a lot of mold growth on surfaces and would explain why mold is growing on more than just exterior walls.
  • Concrete residence was observed on the underside of the upper subfloor/ceiling. This is not mold growth.
  • Evidence of severely dusty walls and flooring. Dirt and dust can provide a growth medium for mold to settle on, and given a humid environment, mold will blossom there.

General Recommendations:

  • General housekeeping of dusting, sweeping, mopping, and vacuuming must be performed on an increased schedule to prevent mold regrowth.
  • Consider vacuuming with a HEPA-filter equipped vacuum cleaner to reduce the presence of mold spores and other allergens.
  • Carpets and padding should be replaced. The current carpet in the basement is holding mold spores from previous issues caused from condensation. The carpets can be cleaned but will likely still have mold spores left over. Replacing the carpet and installing hard surface flooring like vinyl or hardwood is preferred. Sensitive individuals should not live in houses with carpeting.
  • Basement is inadequately heated. A minimum indoor temp of 65ºF must be maintained to minimize excessive humidity and mold growth.

Project Type > Roof Leak Inspection for Mold for a house in Kent

PROJECT SUMMARY

REASON FOR INSPECTION:

  • Owner has been consistently sick for four months and has had some prior damage to roof due to a roofing contractor. Concerned about mold and water damage caused by roofing contractor. Noted that roofing contractor had up to 6 individuals walking on this fragile roof assembly.

PROPERTY DESCRIPTION:

  • This single family residential property is a manufactured home constructed in 1977 and is 864 ft².

CAUSE OF MOLD:

  • The cause of mold is due to a water intrusion from the roof assembly along with high humidity levels in the home.

LABORATORY RESULTS

ANALYSIS OF YOUR RESULTS:

  • No Amplification: No mold spores were measured at levels equal to or above the threshold, and do not indicate a site of probable mold amplification and growth. Please refer to the attached report for more detailed information.

OBSERVATIONS

OBSERVATIONS APPLICABLE TO ENTIRE INSPECTION AREA:

  • An odor associated with cohabitating with pets was present at time of inspection.
  • The home has moisture ants on the property. Moisture ants were found in the bathroom behind the counter, on the kitchen ceiling where the drywall is separating, and on kitchen counters.
  • Most of the ceiling in the home is warped and bowing at least 1 to 2 inches. The roof framing looks to have been compromised due to the amount of roof workers on the roof while doing a repair. The ceiling looks to have had a second layer installed during a remodel to cover existing drywall ceiling that may have been molded. The screws in this drywall show evidence of rust from ongoing exposure to high humidity in the home.
  • Inspection holes were made in two locations to investigate the status of the wall cavities, one in the kitchen and one in the hallway. Mold is growing on all paper backing of both layers of drywall. Mold growth was visible in both wall cavities. Mold growth found inside the vapor barrier of the inspection hole in the hallway. No visible mold growth noted on insulation or roof rafter framing at the two inspection holes cut.

LOCATION: Bathroom

OBSERVATIONS:

  • Light mold growth present on the bathroom window.

CEILING:

  • Light mold growth noted on bathroom ceiling near the closet. This mold growth was the result of a prior roof leak. This leak has been repaired.

SHOWER:

  • Grout and caulking is in good condition and shows no signs of recent water intrusion.

FLOORING:

  • Elevated moisture detected in flooring adjacent to toilet. Often this is due to a slight failure of the toilet seal. No evidence of significant structural damage was observed.

Recommendations:

  • Contact a plumbing contractor to investigate the toilet seal. Replace if necessary.

LOCATION: Guest Bedroom

OBSERVATIONS:

  • The bedroom is equipped with vinyl framed double paned windows with light condensation-based mold growth present.
  • The area under the window appears to have been affected by wind-driven rain water while the window was open. This has affected the drywall tape and resulted in light mold growth on the baseboard below the window.

Project Type > Mold Inspection After a Water Leak for a Home in Kent

PROJECT SUMMARY

REASON FOR INSPECTION:

  • Owner of property found a water leak in the main sink drain from the upstairs. It has been leaking into lower bedroom and caused water damage to flooring and wall substrates.

PROPERTY DESCRIPTION:

  • This single family 2 story residential property was built in 1975 and is 2,240 ft².

CAUSE OF MOLD:

  • Prolonged leak at the kitchen sink drain. Water intrusion.

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.
  • 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:

  • Although your indoor mold spore count is slightly 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.
