Mold Inspection Reports from Bellevue
Below are recent mold inspection projects we’ve completed in the Bellevue area. These reports can help provide you with an idea of the issues we typically encounter in your region.
Project Type > Mold Inspection for a Home in Bellevue
REASON FOR INSPECTION:
- Client has tenants living the basement of their home and requested an inspection due to mold being recently discovered.
CAUSE OF MOLD:
- Numerous active leaks were noted in the laundry room of the basement apartment.
RELATIVE HUMIDITY & TEMPERATURE READINGS:
LOCATION: Basement Laundry Room
- Multiple plumbing leaks were identified in the ceiling of this room during the inspection.
- The first plumbing leak appears to be coming from an upstairs bathroom drain. Water is actively leaking around the base of the bathtub upstairs.
- The second plumbing leak is much larger, and appears likely coming from the sewer stack coming through the floor. Water is actively pooling on the linoleum floor from this leak.
- The partition wall between the laundry room and bathroom has swollen baseboard trim and slightly elevated moisture absorbed into the drywall.
- Elevated moisture detected on the top and the interior of the cabinets.
- The furnace for both levels of the home is located in this laundry area. The furnace appears to be a standard 80% efficiency model with a 1” pleated filter.
LOCATION: Basement Bathroom
- Elevated moisture detected in the baseboard trim and lower section of partition wall behind the bath and laundry rooms.
- Access to the ceiling cavity is present in this area. The cover was removed for inspection. An active leak is visible that is dripping down through the partition wall. This is the likely source of most of the moisture in this area.
CEILING & WALLS:
- Light condensation-based mold growth noted on bathroom wall above shower. This occurs when the warm, moist air generated by shower usage interacts with the cool surface of the walls and ceiling. Without adequate ventilation, this causes condensation and subsequent mold growth.
- See ventilation section above for recommendations to eliminate condensation.
- Contact a plumbing contractor to investigate and repair the leak.
- 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.
- Remove the water damaged wall panels.
- Treat the interior building materials with an application of mildicide.
- Dry out all interior structures.
LOCATION: Upstairs Hall Bathroom
- The client has installed a bidet on the toilet in this bathroom. All bidet water line connections from the wall to the toilet are leaking and actively dripping water on the floor. Water is also dripping into the HVAC vent.
- Elevated moisture was detected in the baseboard trim.
- Bathtub sealant is severely discolored from poor quality and active mold growth on the sealant. This can lead to water infiltration and mold growth/wood rot in the wallboard and framing behind the shower surround. However, because the potential mold growth would occur within the wall cavity, the issue has no effect on the indoor air quality.
LOCATION: Upstairs Master Bathroom
- The client has installed a bidet on the toilet in this bathroom as well. As in the hall bath, all bidet water line connections from the wall to the toilet are leaking and actively dripping water on the floor.
- Significant splashing appears to be occurring from use of the bidet, as elevated moisture was detected in the wall as well as the lower edge near the shower.
- It is indeterminate if shower splashing is contributing to the elevated moisture described above.
Individually, the following types of biological particles were identified in your samples.
*results shown in particles/m3.
ANALYSIS OF YOUR ALLERGEN RESULTS:
- Abnormal Algae levels noted: This appears to be due to the numerous water leaks noted in the laundry room.
Project Type > Mold Inspection of Residential Home in Bellevue
REASON FOR INSPECTION:
Client is a builder who recently had a roof leak cause some damage in one of their homes. Client requested an inspection to determine the extent of the damage and to provide a cost for remediation of the affected areas.
This single family 3 story residential property was built in 2016 and is 4,200 ft². Report 702028
CAUSE OF MOLD:
ANALYSIS OF YOUR RESULTS:
- No Amplification: All mold spore levels were within the normal range of a healthy indoor environment.
- Although the indoor mold spore levels are within the normal range, the on-site examination of the property revealed significant problems that require action. Please review the recommendations below.
- An area of sheetrock has been removed from below the left sink basin to provide an inspection point for the wall cavity. No visible mold growth was observed within the wall cavity, however it is wet behind there which can lead to mold growth in a short period.
- Elevated moisture was detected in the trim around the mirror, and is likely present in the sheetrock behind the mirror as well as the wall that forms the 90º section of the vanity.
- Some elevated moisture was noted in the ceiling of the bathroom near the mirror.
- The areas around the plumbing lines and fixtures in this bathroom are free of evidence of leaks.
- The tile floor is in overall good condition.
LOCATION: Living Room & Dining Room
- The client has had a leak coming from the roof, and significant water damage was noted as originating from the ceiling in this room. A tarp has been laid down on the floor to protect it.
- Approximately 3 square feet of sheetrock has been removed from the ceiling. Some additional sheetrock has fallen, due to the saturated building materials.
- A very small amount of mold is present on the sheetrock that is still attached to the large glue-lam beam dividing the living and dining rooms. A minor amount of staining is visible on the glue-lam beam. This area of sheetrock is saturated, and will require removal.
- There is an area of vertical sheetrock where the dining room ceiling steps up 1’ to the living room ceiling. Elevated moisture was detected in this sheetrock as well, and this will require removal.
- Moisture has also traveled down the exterior wall of the living room, affecting approximately 40 square feet of sheetrock from floor to ceiling.
- Elevated moisture from 30% – 100% moisture content was detected in the studs and sheathing within the wall and ceiling cavity. This will require dry-out.
