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.
Services
Mold Testing Services of Oregon (MTSO), is based in Portland and specializes in mold inspections and mold testing in residential and light commercial properties. Our mold inspection and testing services are used by a variety of clients including home/business owners, property buyers/sellers, tenants/landlords, and realtors.
Each project begins with a discovery call where we discuss pertinent details such as project location, background and client concerns. With this information we can tailor an accurate quote to fit your mold inspection and testing needs. Upon arrival at your residence or business, we will tour the site with the client to view areas of concern.
Using a calibrated Zefon Bio-Pump Plus in conjunction with Air-O-Cell cassettes, air sampling is used to measure the genera and quantity of airborne mold spores within the target area. A minimum of one air sample from outside the structure is required for comparison purposes. Standard turnaround time is 2-3 business days.
Pre-Testing is recommended when a mold problem has been identified but prior to initiating a mold remediation. This service is useful to measure and record the types and quantity of mold spore activity prior to any remedial activities. Such information helps document a professional response and sets a baseline of mold spore activity before the remediation contractor has begun.
Every project is unique, just like the clients we assist. Are you curious about our services and whether they are the right fit for your project? Give us a call and we can quickly generate an accurate quote to meet your specific needs and budget. If after speaking, it is determined that another professional may a better fit for your project, then we can provide contact information for such a company.

Garrett was great to work with. He was responsive and through helping us to discover an issue in our attic which wasn't the reason we asked him to look at and has helped us spot an issue before it became a much bigger problem. I would definitely call MTSO again!

Garrett did an excellent job for us. He went above and beyond helping my college age daughter by inspecting her rental house. He listened to all the concerns we had and did a throughogh inspection. His identification of other issues in addition to mold and the report he wrote helped us get our daughter out of an unsafe house. He is a skilled professional and a thoughtful person that was available quickly when we needed help.
