Mold Remediation for Commercial Properties
Mold in a commercial building can lead to health complaints from employees, liability concerns, and costly property damage. Our team specializes in commercial mold remediation using EPA-approved, non-toxic dry fog technology that treats your entire facility without demolition or extended downtime.

Our Commercial Mold Removal Process

1. Inspection & Assessment
We perform a thorough inspection of your commercial property to identify all mold-affected areas, moisture sources, and the scope of remediation needed.

2. Dry Fog Treatment
Our EPA-approved dry fog system penetrates every surface—inside walls, above ceiling tiles, and through HVAC ducts—eliminating mold spores without demolition or harsh chemicals.

Signs Your Commercial Property Has a Mold Problem
Mold can spread through a commercial building quickly, especially in the Pacific Northwest’s damp climate. Watch for these warning signs:
- Musty or earthy odors in specific rooms or near HVAC vents
- Visible discoloration on walls, ceiling tiles, or around windows
- Employee health complaints such as allergies, headaches, or respiratory issues that improve away from the building
- Recent water damage from roof leaks, burst pipes, or flooding
- Condensation buildup on windows, pipes, or cold surfaces
- Peeling paint or warped surfaces indicating moisture behind walls
If you notice any of these signs, it’s important to act fast. Mold spreads rapidly and the longer it goes untreated, the more extensive—and expensive—the remediation becomes.
The Cost of Ignoring Commercial Mold
Health & Liability Risks
Mold exposure can cause respiratory issues, allergic reactions, and other health problems for your employees and customers. Unaddressed mold creates potential liability for workplace health complaints and OSHA violations.
Structural Damage
Mold feeds on organic materials like drywall, wood framing, and insulation. Left untreated, it can compromise the structural integrity of your building, leading to far more expensive repairs down the road.
Business Disruption
Traditional mold removal methods require extensive demolition and can shut down your operations for weeks. Our dry fog system treats the problem in days, not weeks—keeping your business running while we work.
