We have offices in Vancouver, Portland, and Sunriver and offer the flexibility and time sensitive response required in today’s dynamic marketplace. Mold Investigations can quickly determine whether there is a mold problem, identify potential causes, offer timely and cost effective solutions, and conduct corrective actions to solve the issue.

In addition to mold and indoor air quality, our firm manages a wide range of environmental issues including hazardous materials, asbestos, lead, PCBs, underground storage tanks, etc.
