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.

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!
Your company has quickly become our go-to. Excellent responsiveness, fast scheduling that accommodates the fast-paced real estate world, and stellar professional completion on each and every job keep us coming back again and again. Thank you!
This company is the best. Customer service is exceptional. We needed an inspection and mold remediation right away due to a closing deadline, and they made their schedule with so they could accommodate us. I am so grateful for them and their willingness to work with our needs. Their work quality is also grest and professional.
We have used your services twice and both times we had an excellent communication, step by step explanation of the professional services. Both times workers came on time, were friendly and answered all questions! We had an issue last time when workers were unable to access the roof. Hailie called right away,…
I love this company! Very knowledgeable , friendly, efficient and prices are very fair.
We called Certified Indoor to check out a mold problem in a home we were buying. They were very quick with their response. Once they provided an estimate, the sellers agreed to pay for the remediation. Certified Indoor completed the job within a few days. The folks that work there are friendly, helpful and thorough. We would call them again!!
In the process of buying a new house in the middle of covid-19 pandemic. It was recommended by our realtor to have the house inspected. On the inspection of our new house mold was found in two of attic spaces. To fix problem we just needed to make a appointment and these awesome professionals at Certified Mold…
I highly recommend Certified Indoor Environmental company. They’re knowledgeable, professional and on time! My water heater was leaking for a while and unfortunately I totally missed it until it caused significant damage to the wall and created nasty black mold. These guys fixed everything perfectly!
The guys were amazing that showed up. Very professional and friendly. I would highly recommend this company!!
This company was super responsive, communicative and most importantly, honest. I had another company come out to give me a bid and it was obvious they just wanted to make a buck, they barely looked at the smaller side storage areas and just wanted to see the attic. Their bid was more than double. Certified was…
Love this company. They have amazing prices, are professional, and timely. I am a real estate broker and they have saved several of my deals.
My experience started out awful - I came home to a house that reeked of bleach and was uninhabitable. Worse, I was days from closing the sale of the house - and I feared my buyer would balk. As it turns out, a series of unexpected circumstances and minor mistakes had come together into a perfect storm. That's when…
These guys came recommended from my realtor and her company. The inspection felt thorough and we were given options and honest takeaways. No brainer to schedule them due to the guarantee they offer and seemingly quality of work. The job done exceeded my expectations with the friendly servicemen and prompt resolution. A+
These guys have a great team! They were friendly, efficient, great communicators and the quality of work was excellent. CIE - Thank you for making the repairs process a smooth one for my Sellers!
CIE was a fantastic company to work with! We hired them for a massive mold mitigation project. They were professional, knowledgeable and I felt like their prices were extremely reasonable. Great follow up and communication from their staff, too!
Very professional and friendly staff! I definitely recommend them!
Both workers were nice and did their jobs efficiently. The before and after photos were an essential touch!
I would highly recommend this Certified Indoor to anyone. I had no idea how they could remove the mold and make the roof sheathing look like new in the attic. I assumed there would be no option but to tear all the roof sheathing off and replace it. I cannot think of any more dismal place to have to work in, as…
I'm a Realtor and my clients have used Certified Mold for years for their attic mold remediation and were very pleased. Great value, before and after pictures, warranty and professional and reasonable.
We were able to get a no-cost inspection and recommendations for the remediation in our home's attic area while we were in the buying process it and then had the work completed after we closed. They kindly accommodated us with the Estacada fire evacuation and rescheduled for a later date. All finished now. On the…
Very knowledgeable, helpful and thorough. I appreciate their work.
Always a pleasure and my clients are always happy - thank you! Good people, professional and kind, competitive pricing and good warranty.
Got the job quickly and efficiently. Provided photos of the work done which is a valuable resource in a real estate transaction.
We appreciate your coming to us with a discount on the project due to the time it took to do certain tasks. Unprecedented customer service!
Very professional, reasonable price, have used them on several transactions.
