They came in and did some investigating and got back to us quickly with a plan of action, cost, and schedule. They followed through on everything in a timely manner and gave us tons of pictures and reports for our records and to help our tenants feel safe.

Very knowledgeable.
Great company to work with on mold remediation!
Simply the best! My job crew were highly trained and professional -- and they were not to busy for being plesant to talk with. All my questions were answered and I had full confidence the Job was being done right! Arrived in a new truck - all of their equipment was well maintained and organized -- the job site was…
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!
Tilly and Efran at Certified Indoor Environmental were incredible to work with! They were on time, courteous of our space, clean, professional, educated us on what they were doing, and the finished work looked so much better! I highly recommend Certified to anyone needing mold removal, and recommend you ask for…
Jose and his team were great, very professional and cleaned up after as if they were never here. Very thorough job and excellent customer service overall from estimate to the job.
Certified Indoor Environmental was a pleasure to work with from start to finish. Everyone we spoke to was helpful, professional, and friendly. We originally received a quote after finding mold in the inspection conducted on our new home. Once we closed on the property, we were able to schedule the job quickly.…
Everyone from start to finish were pleasant and professional to work with. We feel confident in the completion of our project that everything was done right! Thank you!
The crew did everything we expected and did very well. We are very happy with the seervice and with the work.
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.
They were professional, efficient. Very work oriented and, by the way they carried themselves, they were well trained. They took pride in their jobs and worked well as a team. Very impressive for relatively young men.
The staff was on time, professional and done on time. The improvement was immediate and they put it new vent ducts and vent screens under the eaves which look much better than the vent holes.
It is always an absolute pleasure to work with your team. All of your staff is always professional, kind and efficient. THANK YOU!
Awesome responsiveness and professionalism. They did a fantastic job!
I really like this company. They answer their phones, and are very responsive. They find ways to schedule within your timeframe. They are aware that, in real estate, we are bound by deadlines and they seem to really want to help in meeting those deadlines. In addition, their pricing is reasonable,
Great communication from both the onsite staff and the office staff. Easy to set up an appointment, great followthrough, timely. They came to do exactly what was in the estimate/quote. No surprises. Professional all the way.
The two guys that did the work were on time, very nice, and they even alerted me when they left :)
Everyone I spoke to was professional and very friendly. They were on time and they were clean.
Thank you for helping us with repairs in our attic and crawlspace! Service was professional and well done.
Certified was great. They remedied the mold problem and fixed a detatched vent that was non-functional. They let themselves in via lockbox and accepted payment via escrow closing and sent comprehensive follow up photos to show all the results. Everything was totally professional and made getting this issue addressed very easy.
I looked up 4 company's to fix my mold problem and decided on certified do to response time, professional explanations, nice and friendly, good pricing, and proved why they have the best reviews. Great job and I have given their names to a couple home owners on my street. Mike
Technicians were on time, friendly and helpful. Pictures of all work completed before and after. Work area was clean and job was done in the budgeted estimate given! Great company
Reasonable quote, good responsive communication and professional workers
I highly recommend Certified Indoor because of their professionalism and follow through. The entire process was clear, prompt communication, and I knew what to expect during and after my mold removal. I am also receiving support after my job to ensure the job is done right. To work with this company because of the items listed above is a refreshing change.
Clearly communicated regarding what needs to be done, was on time and provided before/after image to confirm, which was helpful. I would recommend.
Got this done super fast and at a very competitive price.
Our attic had a lot of mold on the underside of the roof. The guys from Certified Indoor Invironmental were super friendly from start to finish. They were careful throughout the house with ladders and tools. When they left there no more mold. Plywood was clean as a whistle. I give them 5 stars ⭐️ ⭐️⭐️⭐️⭐️
Thank you for the excellent service! Fairly priced, timely and provide great communication.
Had them out for mold mitigation and to install better ventilation. They had great customer service and they made scheduling very easy. They performed the work quickly and it passed inspection. Very good company to work with.
Excellent customer service and thorough work!
