Likely moisture source: exterior grading or drainage directing water toward the foundation. Recommend correcting grade/downspouts at the marked wall.
Before and after
Surface after dry ice blasting, same angle as the pre-work photo. Growth removed from the substrate without added water or chemicals.
Moisture readings
Each reading is set against a dry standard taken from the same material, unaffected, nearby. A reading with no reference is reported as unjudged, not as acceptable.
- Instrument
- Delmhorst BD-2100, pin-type, %WME
- Atmospheric
- 68°F, 41% RH at completion
| Stage | Location | Material | Reading | Dry standard | Assessment |
|---|---|---|---|---|---|
| Pre-remediation | rim joist, NE corner | framing lumber (SPF) | 24.1% | 11.8% | Elevated +12.3 |
| Pre-remediation | joist bay 4, above grade line | framing lumber (SPF) | 19.8% | 11.8% | Elevated +8.0 |
| Post-remediation | rim joist, NE corner | framing lumber (SPF) | 12.4% | 11.8% | At reference +0.6 |
| Post-remediation | joist bay 4, above grade line | framing lumber (SPF) | 12.0% | 11.8% | At reference +0.2 |
Method and controls
Dry ice blasting (solid CO₂ media), followed by HEPA vacuuming and waste removal. No water and no chemical biocides were introduced.
- Scope
- Joist bays and rim joist at the NE corner, ~180 sq ft.
- Standard
- Work performed following the practices of ANSI/IICRC S520, the Standard for Professional Mold Remediation, which sets source removal as the objective and defines the Condition classifications used in this report.
- Containment
- Containment established with 6-mil poly sheeting and zip-wall at the affected area. Negative air maintained for the duration of the work.
- Pressure differential
- -0.03 in. w.c.
- Certification
- not recorded
Verification
Visually clear of growth · No musty odor remaining
Same meter, same locations as the pre-remediation readings. Substrate returned to the reference range for this material.
The verification recorded here is the remediation contractor's own visual and moisture check on completion.
It is not third-party clearance. No air or surface samples were collected and no laboratory analysis was performed.
Where independent clearance is required — by an insurer, a lender, a tenant dispute, or your own policy — engage an indoor environmental professional independent of this company to perform post-remediation verification.

What this report promises, and what it does not
The water is the job
Growth returns wherever moisture returns. Correcting the source named in this report is the client's responsibility, and the condition recorded here holds only for as long as that source stays corrected.
We report what we could see and reach
No walls, floors or ceilings were opened. Conditions in places nobody could observe on the day of service are outside this report, and we offer no opinion on them.
No one can certify a building free of mold
Spores exist in every building, indoors and out. What a remediation can honestly claim is that the growth found was removed and the area returned to a condition comparable to the unaffected parts of the same building. That is what this report records, and it is all it records.
This is a record, not a laboratory result
The readings and observations here were taken by the technician with the instrument named in this report. No samples were collected and no laboratory analysis was performed. Where a third party requires laboratory clearance, an independent professional should be engaged.
- This report covers only the areas and materials listed in the scope. Areas not listed were not inspected, and no opinion is offered on them.
- Findings describe conditions observed on the date(s) of service. Building conditions change, and moisture can return whenever its source is not corrected.
- No destructive investigation was performed. Conditions inside wall cavities, beneath flooring or above fixed ceilings were not observed unless specifically noted.
- No air or surface samples were collected and no laboratory analysis was performed as part of this work.
- This company performs remediation. It does not provide medical opinions, and nothing here should be read as an assessment of health effects.
- Determining the cause of a water intrusion may require a licensed plumber, roofer or engineer. Where a probable source is named here, it is the technician's field observation, not an engineering finding.
- Photographs are representative of the conditions observed. They are not a complete record of every surface in the work area.
- This report is prepared for the client named on it, for this property and this date of service. Anyone else who relies on it does so on their own judgement.
- The work addresses growth and the surfaces it was found on. It does not correct the source of the water, and the result holds only while that source stays corrected.
The observations and work recorded in this report were made and performed by the undersigned.
