"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."

"Paul Jose inspected the attic for possible mold and ventilation. He found none, and air humidity was in normal limits that would not support mold. He checked all my vents that go through the attic for leaks or other problems. He made a recommendation to improve air quality in attic. When he was running a little bit late, he called me to tell me he would be there soon. Very personable."

"If you have or even think you have mold/fungus issues in your home, Virgil Pelton is the man to call. Not only is he knowledgeable, and professional, he will hold your hand and help you to resolve your issue. I used his recommend remedial company and they were fabulous. He helped me every step of the way from the time I called him to when all was done and no more mold/fungus!! He is honest and reasonable. Please, anyone out there who may have mold issue PLEASE contact Virgil. You want the air tested before and after remedial work. To make sure there is NO more mold spores in the air. He answers any and all questions. And explains everything in detail. He is a very calm guy and he prayed for wisdom before work. And prayed after the final visit. Wow!! He is God sent for me. We dealt with this mold issue since 10/2020. We should have called him first and saved a lot of headache and money$$$."

"I thought he did a good job explaining what he did do but very disappointed they didn't explain that you had to pay a lot extra money to actually find out what kind of mold if any you had. The $199.00 fee they only looked for mold & tested the air quality. If they found any mold it cost a lot more to find out what type. He did say we had mold in our crawl space but not what kind, that cost more money. Overall good for what he did do."

"I recently had Pure Air come out to do an air quality test for my home, and I’m really impressed with their service. They arrived on time, explained everything clearly, and made the whole process super easy to understand. They tested the indoor air and also compared it with the outdoor levels so I could see exactly what was going on."

"Jose was very professional and prompt. He came out in 90 degree heat and did full inspection in non-air conditioned home. Everything came back clear. In February it started raining constantly and I started seeing mold on one of my walls that I was concerned with before.  He came back out to recheck since it was so dry in July. Was very thorough and came the day after I spoke to him. I have a very weak immune system and was very concerned and he helped me tremendously by checking everything and giving me recommendations on how to remedy the issues. Would recommend him to anyone.

FAQs for indoor air quality testing projects in Seattle, WA

You should test your home's air quality if you or your family experience health problems like allergies or respiratory issues, as these could be linked to indoor contaminants. Also, consider testing if you're concerned about mold, radon, carbon monoxide, or if you've recently had home construction, demolition, excavation, or remodeling that could have released chemicals into your indoor air.

An indoor air quality test typically takes one to three hours to complete. After the inspection, you'll receive a detailed written report within two to 10 days. The evaluation includes comprehensive air sampling from all designated areas in your home. Your specialist will review the findings with you and provide clear guidance on steps to take if any issues are found, helping ensure your indoor environment meets health and safety standards.

A certified indoor air quality consultant or inspector is the right professional to perform your indoor air test. While some home inspectors have certifications, they often subcontract this specialized work to trained professionals with advanced tools. This expert will thoroughly evaluate air samples from every area in your home and clearly explain the findings to you. Be sure to confirm your tester's credentials before scheduling your service.
