Our Mold Remediation Process

01

Inspection & Testing

We inspect visible mold and may conduct air quality and surface sampling to determine the extent of contamination and mold species.

02

Containment Setup

Affected areas are contained with plastic sheeting and negative air pressure to prevent spores from spreading to unaffected areas.

03

Mold Removal

Porous materials with mold (drywall, insulation, wood) are removed and disposed of. Non-porous surfaces are HEPA-vacuumed and treated with antifungal agents.

04

Moisture Source Repair

We address or coordinate repair of the moisture source — leaks, condensation, or drainage issues — to prevent recurrence.

Mold Remediation FAQ for San Francisco Homeowners

How often should San Francisco homeowners get mold remediation?
Given San Francisco's karl the fog: persistent summer fog from the pacific keeps temperatures at 55–65°f on the west side, most homeowners benefit from mold remediation at least once a year. Year-round fog moisture causing wood rot and paint peeling on west-facing Victorians often makes spring or fall the optimal time to schedule service.
What home types in San Francisco most need mold remediation?
Victorian Painted Ladies and Edwardian flats (most common exterior) and Spanish colonial and stucco in the Sunset and Richmond districts are the most common home types in San Francisco and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
How dangerous is household mold?
Mold exposure can cause respiratory symptoms, allergic reactions, and in sensitive individuals, more serious health effects. Black mold (Stachybotrys) gets the most attention, but any significant mold growth should be addressed.
Can I remediate mold myself?
Small areas (under 10 sq ft) can be DIY-cleaned with appropriate precautions. Larger infestations, mold on HVAC systems, or cases involving black mold should be handled by certified professionals.
Will mold come back after remediation?
Mold returns if the moisture source isn't addressed. Remediation removes existing mold; preventing recurrence requires fixing leaks, improving ventilation, or reducing humidity.
Does homeowner's insurance cover mold remediation?
Coverage varies widely. Sudden water damage from a covered peril (like a burst pipe) that leads to mold is often covered. Mold from long-term neglect or flooding is often not.
