"These guys are the best in the business. I suspected a mold issue in my bathroom, so I called up PNW Mold Masters. They were able to get a technician out in less than 24 hours. Service tech was extremely knowledgeable, professional, and very friendly, which made for a delightful interaction. They did detect mold in my bathroom and promptly came up with an action plan to correct the issue. All in, I had mold problem resolved within 48 hours of my initial call. I would highly recommend PNW Mold Masters to anyone looking to get a test or removal of mold at very market competitive pricing. 10/10 experience. Will call them again for any future issues."

"It went great. I love Angies list. Brandi from Armored Restoration contacted me immediately and we went through the details and she had the crew come out and figured out my water problems. They had to work in the worst conditions where other companies didnt even wanna touch it or even call me back. It was a lengthy process to get everything back to new but was to be expected with how long everything was wet and damaged. At first I was mad cause I had to pay so much to fix everything that was wrong. But now after its fixed I dont have any respiratory problems or allergies or running nose and headaches. I had no clue how bad the mold was affecting my life. Glad I waited to post a review. Thanks for saving me!!"

"I wanted to give them an F for fantastic, but your rating system wouldn't get it! I was selling my house and an inspection came up with mold in my attic. I was devistated, but called the best. Ryan came out first, to look things over. He gave me an honest appraisal of what was there. His crew showed up and it was total professionalism from the start to the finish. During the process my family and I were protected from the mold. Set up and clean up each day was precise so I could have a normal life. I have dealt with many companies in the past, but they go way above in all things! If I could rate them higher than A I would."

"Yoni did a great job removing mold and fixing the source of the moisture which is the broken exhaust fan ducts. Would definitely work with him again on other projects."

FAQs for mold & toxic material test projects in Portland, OR

Some companies offer a no‑cost phone or video consultation that screens for red flags. If the discussion points to a real issue, the pro will recommend a paid on‑site inspection. The complimentary call clarifies whether you need full testing, but it isn’t a substitute for samples, lab work, or a written report. Always confirm what the free service covers before you schedule.

A standard inspection, which includes basic air and surface samples, takes an average of two hours. If the pro needs to probe hidden spaces, such as wall cavities or ductwork, plan on up to six hours. Extra time allows the inspector to reach tight areas, collect additional samples, and document findings. Lab analysis is a separate process and often adds several business days to the overall timeframe before you receive the full report.

Mold thrives where moisture lingers and air flow is poor. Common hotspots include bathroom walls, kitchen backsplashes, window sills, HVAC vents, fireplaces, crawl spaces, and enclosed attics. Check these areas regularly—especially after leaks or high‑humidity weather—to catch growth early and avoid costly repairs.

Unchecked mold can knock 20% to 37% off a home’s market value because buyers worry about hidden damage and health risks. Even after remediation, visible staining or a history of major moisture issues can still lower offers and prolong the time on the market. Addressing mold quickly protects both your property’s structural integrity and its resale appeal.
