I had a great experience with this company from my first point of contact with them until the final inspection report was delivered. They are great with client communications, they perform great work - Craig (the inspector who came onsite) was very professional, detail oriented, and thorough, and their rates were reasonable. Highly recommend this company if you are in/around Portland.

Craig was extremely thorough and careful as he went through the house. While he didn't find any water intrusion/mold, he gave us some suggestions to perhaps eliminate the order I was smelling (which of course my husband couldn't smell). He was personable and spoke to us in lay terms, but not like we were 5 year olds.

We were very happy with the service from start to finish! When making the appointment, the entire process was described in detail, including prices, and when Craig got here, he went over how the inspection would go. Having that context—the people being good communicators—makes a big difference! Craig was happy to answer our many questions. He wrote up recommendations for lab tests in 5 places and we elected to do 4 of them. There was absolutely no pressure to do more, and no "selling" of any kind at all. We felt that Craig was mindful of what tests would be useful, and explained that well. We also felt he was earnest, helpful and there to get a job done well, rather than to make the company as much money as possible. The report came on time as promised and was easy to understand. A lot of people would say the service is overpriced just because they aren't too thrilled to spend a good amount of money. I think it's reasonably priced—people don't tend to consider all the costs for service like this: time spent traveling, sending samples to the lab, writing the report, time on site (several hours), lab fees, the inspector's experience and expertise, and the people who manage scheduling and bookkeeping and payroll... and I'm probably missing something.

Craig was professional, knowledgeable, prompt and courteous. He gave me a good idea of what to expect in dealing with the mold problem, which was a big help since I've not dealt with such things in the past.

Craig was prompt, professional, thorough and very knowledgeable. He took time to explain things to me and answer my questions. His report was easy to read and his partner called to go over the report and answer any questions. Every contact I've had with the people in this company have made me feel comfortable. It is clear they care about providing a good service for their customer.

Craig's mold sampling results came back quickly with very high degrees of compromised air quality. Craig recommended Oregon Restoration to do the cleanup, which resulted in removing everything from the contaminated rooms, sealing off the back of the house, removing sheetrock, carpeting, flooring, and insulation. Craig then returned after the mold was mitigated and did further mold samplings. The house is now mold free.

I researched mold inspection companies and read excellent reviews on Craig Cooper the local Mold Inspection Sciences inspector. I met Craig I told him he had a great reputation and I expected him to live up to it. He did and far more. Craig's pre-remediation inspection identified the type of mold. But Craig went beyond that. He is a great teacher and he educated me on the probable cause of the mold, various methods of mold removal, and provided the information I needed to select a remediation company. Brad of the MIS staff was also extremely helpful. I selected a firm that used a remediation method that Craig and Brad had recommended. The work was completed in a timely manner and passed with flying colors.

All went well. I would highly recommend Mold Inspection Sciences as a company with a high standard of expertise. We now have a clear picture of how to bring our basement back to its former pristine condition. Because this company does not perform mold remediation, but only makes recommendations based on data found, there is not a conflict of interest. For this reason as well as the knowledge and professionalism of the inspector, we have confidence in their assessment.

We had a great experience with Mold Inspection Sciences; Craig was prompt in setting up an appointment, punctual the day of the appointment, and very patient and friendly as he explained a number of technical factors related to our house and the characteristics of mold. We will hire him again once our remediation is complete to do the post-remediation verification of our contractor's work. Highly recommended. The only reason I gave them a 'B' on price is simply because I haven't hired this type of work from any other company before and therefore I don't have anything to compare them to, so I didn't feel like I could give them an 'A' because of that; but I certainly thought their price seemed reasonable for the scope of work completed.

I had an outstanding experience working with Mold Inspection Sciences. After discovering mold in my home, I engaged Mold Inspection Sciences to perform an analysis. Craig came out and did a thorough examination of my entire house, identified risk areas, and took several air samples. Afterwards, he provided a very detailed report, which noted both the outcomes of his testing and specific remediation steps for each area of concern. After I had my home remediated, I asked Craig to come back and retest. Once again, he did a very thorough examination and provided great documentation of the results. On both occasions, Craig was professional, knowledgeable, thorough, and informative…and was really nice to boot! He was also very responsive to my follow-up questions after his visits. Without hesitation, I would highly recommend Mold Inspection Sciences!

Craig was very professional and informative.he explained everything in great detail. <br />He also listened very well to all of our concerns. <br />There was some additional optional testing that we learned about and he was very honest about how it can be viewed by insurance companies and left it up to is as to how to proceed. <br />We received the test results quicker than I had expected and he every called and left a detailed <br />Voice mail explaining a summary of the state of our house. <br />

They came out and investigated, and while they did not find evidence of mold they did find evidence of animals. <br>They were very professional and thorough and I would use them again for any mold problem.

Mr. Craig Cooper was punctual. He listened and observed. Then he explained what he was going to do. As her performed the testing procedures, he patiently explained what he was doing and why. At the end of the inspection, he indicated taht the analytical results would be completed by the next Wednesday. The report was emailed on that date and was followed up by a telephone call which explained the results in detail. I was very impressed with Mold Inspection Services- Portland, Oregon!

<p>Craig Cooper was the specialist who worked with us. I talked with Craig on the phone prior to the inspection visit and all the charges were exactly in line with what he had laid out in the phone call prior to the visit. He was prompt, very thorough, explained all the steps he was doing, and explained what some possible next steps would be. He gave me some contact names for local mold remediation companies since his company only does inspections and does not handle remediation. Craig was very friendly as well and answered all of the questions that we had.</p> <p>The samples that were obtained onsite were completed right when he said they would be. We appreciated him coming out on such short notice right before the holidays started up. I would definitely recommend Mold Inspection Sciences, to others.</p> <br />

Craig was amazing. Very professional and very thorough not only in his explanation of services before making the appointment but in performing the actual inspection. He was prompt---and he was very kind. He explained my options and he laid out the costs so everything was clear....he allowed me to make the decision regarding more testing without any pressure from him. He never tried to up sell me or get me to purchase more tests than what I wanted. It was very comfortable doing business with him. He got back to me on the day he said he would with the test results. We are actually going to use him again for our business location because he was so above board. There was no guessing as to what it would cost. It was all laid out very clearly before hand. He is not the cheapest out there but the quality of his service was AMAZING!!! <br /> He knows his stuff. He answered all my questions without getting frustrated with me and he seemed to genuinely enjoy his work. I would highly recommend him and this company. <br />

It went very well. We have a big house so we didn't want to do all areas but they came up with a plan that would keep costs reasonable and cover the areas we knew to be the real potential problem zones. Every step was explained well and I asked a ton of questions which were answered in detail. Also the report we got after we sent in samples was very clear and helped me to put my mind at ease. The rep was a good guy, not in a rush so we talked at length while the tests were running and I followed him around for most of the inspection which was kind of fun, I learned a lot and I'm now resting assured that we don't have sneaky mold issues around the house. <br />
