About Mayes Testing Engineers, Inc.

Mayes Testing Engineers, Inc. is a construction materials testing and inspection firm and one of the leading providers of construction quality assurance services in the Pacific Northwest.

Where you can find us:

We perform onsite inspections at some of the most recognizable landmarks in the region and perform lab testing at each of our fully certified, state-of-the-art laboratories in Seattle, Tacoma and Portland.

Where we started:

We began as a one-office company in 1984 and have expanded to three offices in Seattle, Tacoma and Portland with more than 100 employees. Before Michael Mayes founded Mayes Testing Engineers, he saw the high turnover rate of inspectors in the testing and inspection industry. He designed our company to train inspectors on a higher level with multiple inspection certifications. The result is highly-qualified inspectors with extensive experience and an in-depth understanding of their craft.

Where we are today:

Our project managers and inspection managers each have at least 15 years of experience in testing, inspection and consulting. Among the Mayes Testing Engineers, Inc. management staff are some of the most experienced materials engineers in the region. Our principals are full-time registered Professional Engineers. We have materials experts in welding, concrete, soils, masonry, asphalt and non-destructive testing.

Mayes Testing Engineers has been named a "Best Company to Work For" by Washington CEO Magazine and one of "Washington's Fastest Growing Companies" by the Puget Sound Business Journal, four times.
