Gerry arrived on time and was very personable. He said he would look in every nook and cranny including cupboards, etc. After his inspection he showed me his findings and explained about taking samples and asked permission for the air samples, as they were $100.00 each. I agreed to all procedures and costs because I felt it was important to know everything. The report was e-mailed to me on the 3rd day as promised and it was very scientific with pictures and readings and all kinds of information. They called to let me know it was done and I appreciated that. I needed to call a few times afterwards with questions and they were always there. The secretary was especially nice because she listened to my concerns regarding some one I hired whom I didn't think was getting the job done right., and also because it was someone they recommended for me because I asked them to give me recommendations.

After receiving the report, and before and after hiring their recommended company, I began looking at the surrounding areas and found more items which had mold. All of my findings were in the very rooms that had been inspected. I found mold on furnishings in our basement main room, which was not included or noted in the report. It has also since been found in our garage..........I felt sure he had looked in the garage because I saw him enter the house from the garage door at one point when I went downstairs to see if he needed anything. This mold is mostly in the insulation on the garage ceiling and some surrounding wood which was found by a home inspector I hired. ..This inspector also found that the wood floors in both bedrooms above the garage showed higher than normal humidity readings and the entire basement flooring is at a 16% reading. ( that would explain the mold found on the furniture) I am so disappointed. I feel I paid 399.00 for someone to find half the mold. I thought I was hiring experts and could rest assured that every room had been thoroughly looked at. I can only assume that checking the flooring for moisture during a mold inspection is optional.

If anyone out there is going to have this kind of inspection I highly recommend staying with the person and really looking at everything because you know your home best, making sure you and the inspector have looked at every possible place for your own peace of mind. I was worried and thought I might be in the way. There was a lot of stuff in all the rooms, however I did offer to move anything to help him get through his inspection. He never asked and I assumed all was well. I'd like also to mention that in the report, after each description of the separate findings, the statement is made that "hidden mold is possible". I learned that getting a thorough inspection is really not possible.

"We appreciated the responsiveness and professionalism of PNW Mold Control. They did the less expensive fogging method in our attic. Tests were done by an inspector after the work was completed when we were in the process of selling the house which came back negative for mold. Very satisfied!"

"I have only good things to say. Pascal was super responsive, professional, explained the mold testing process and what kind of air samples he recommended. The results were ready within 2 days, along with a detailed lab report and an explanation of the report that was easily understandable. I would highly recommend this company to anyone looking for professional testing of mold and other contaminants."

"This company is very expensive but I was happy with the detailed report that I got. They charged me $100 for a mold alarm but did not send me any instructions and will not tell me how to use it over the phone. So that was a huge waste of money. Phillipe collected the swabs and was pretty amazing. I appreciated him taking the time to show me some of his concerns. They charge $400 for two air samples and two swabs. Very expensive. The person who called me to go over my report was amazing. She was very helpful and provided me with additional resources. If you have concerns related to toxic mold or are pursuing a lawsuit then I would recommend them but they are the most expensive"

"Overall a wonderful experience. I got to experience the customer service portion and they were professional and friendly. They did some exterior mold/clean up work and we had an upstairs shower leak into the lower bathroom which turned into mold and ruined sheet rock. Colby was able make it look new. Would hire again. Good pricing too"

FAQs for mold & toxic material test projects in Seattle, WA

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.
