Quality people and good communication. Unlike many contractors they showed up on time and were efficient and did a good cleanup.
i love using certified. I always get residents who would rather trust someone who works in the field, than a manager who doesn't work with growth. You guys are always so willing to come out and explain to the residents what's causing the growth. Very nice to work with as well! You guys are usually the first to call in terms of vendors
Very polite and professional
Great experience with customer service, scheduling and tech's doing the work. Good communication. Terri Boughton, Licensed Realtor in Oregon
We are extremely pleased with the work done. The technicians were great! They worked nonstop, in rain that alternated between drizzle & pouring AND it was very windy. They were courteous & professional, did an excellent job, and an excellent clean up before they left. Great work! Amazing looking results! Not ten stars..more like 20 stars!! Thanks!

Great work!
I can always trust Certified Indoor Environmental to provide thoughtful recommendations and, further, to understand and accomodate my clients goals and concerns.
Terrific service, they even contacted me over the weekend when I sent email request through the website. I was really happy with how quickly you were able to get out to the property and the text messages, as much as we hate having this issue come up in a Real Estate transaction, it's awesome to know you are a dependable company.
On time and did professional way..
Certified Indoor Environmental was fantastic to work with. They were able to schedule an estimate and the work to be done very quickly, and were considerably cheaper than other companies I talked with. I would definitely use them again.
