**Updated/2nd Review May 2023** If you are thinking of using this company, you may want to reconsider. After using Certified in May 2022 I had insulation installed and a new mold issue arose due to poor baffle placement blocking the smart vent air flow. Certified (now Alliance) called me the day after sending the…
Project Manager Freddy Rodriguez came out to inspect my attic. He was very knowledgeable and was able to assess the ventilation issues and condition of the roofing sheathing. I appreciate his expertise.
Certified Indoor is my Go-To for all things MOLD/Fungi related. They are always quick to get out, extremely professional, and competitive with their bids. When it comes to the actual mitigation, there's no company I trust more!
Your onsite personnel we very polite and professional. They answered all my questions and made me feel comfortable about the process. I would totally use them again and recommend them to my friends.
You guys are simply the best! From start to finish you have been professional. Enviromental did some mold remediation for me. They were excellent ! From the receptionist to the technician everyone was professional and responsive.I was on a deadline and they met the deadline with ease.Call them you won't be disappointed.
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 professional experience and they took care of getting the mold out of the condo attic in a timely manner. Lots of pictures and detailed report.
They helped us inspect and resolve mold issues in the attic of the property.
The employees were really friendly and helpful. They got it done quickly and cleaned up afterwards. They knew someone else had done an estimate from the original owner of the house, they took a look at it and adjusted their prices without me even saying anything. They sent pictures of the before and after. They gave…
Very knowledgeable.
I have worked with Certified Indoor Environmental numerous time. They are professional and do a great job. I find their bids to be reasonable, and the communication excellent and clear
We were SO pleased with the Certified Indoor Environmental team. They are great at what they do and we felt taken care of with the services they provided. With kindness and hard work at the core of what they do we couldn't recommend them enough!
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…
Certified was great! Some issues were found during inspection (thanks, PDX Inspections!) and Certified provided a quote prior to closing. They honored my quote and it was easy to get scheduled They added several vents for the attic and did some mold mitigation. They did a great job and were very professional.
Great great service from the office staff and the service techs. Amity was so helpful with all of our questions and very responsive. Definitely recommend to friends and family.
Quality people and good communication. Unlike many contractors they showed up on time and were efficient and did a good cleanup.
Professional, available (quick to estimate and do the work), delivered as promised.
Certified arrived on time, responded to calls and did a professional job. The techs were friendly and responded to questions without hesitation. I would use them again without hesitation.......
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
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…
The crew did everything we expected and did very well. We are very happy with the seervice and with the work.
I was so impressed by the knowledge, detailed inspection, understanding, time and courtesy to address and explain all concerns. If they did regular home inspections, they'd be amazing! AMAZING!
Very timely, complete IAQ testing, results returned in just a few days
Excellent communication and response time. 100% recommend CIE.
Communication disappointing. Messages not returned, 2 day delay with returned call once I spoke to office. Was not on site at time of service but was told guys were great.
From office/scheduling staff, to project manager, to the techs who performed the work, my water damage issue was addressed with a sense of urgency and professionalism. I would not hesitate to recommend Certified Indoor Environmental.
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.
It is always an absolute pleasure to work with your team. All of your staff is always professional, kind and efficient. THANK YOU!
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.
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.
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
Thank you for the excellent service! Fairly priced, timely and provide great communication.
