Garrett Dayfield

Hi, my name is Garrett Dayfield and I am the proud owner and operator of Mold Testing Services of Oregon. I was raised in NE Portland and am a second-generation mold inspector. MTSO was founded by my father in 2002 and at that time, was one of the first companies to provide residential mold inspection and testing. I started assisting with inspections and daily operations in 2005 and assumed a full ownership role in 2010 when he retired. In most cases, you can anticipate me to perform the inspection at your residential or commercial property.

Mold Testing Services of Oregon, LLC (MTSO) was founded to provide thorough and reasonably priced mold inspections and testing services. We have assisted clients in literally thousands of residential and light commercial structures throughout the Portland Metro area. Our vast experience in this field gives us a unique perspective on mold, moisture issues and associated testing.

At MTSO we value our clients and their concerns and will gladly take the time to discuss your project to tailor a mold inspection and testing process to meet your specific needs and budget.
