I called Rich the day before for an appointment and he agreed to come in next day morning. He arrived early and started the work and finished on time. He also agreed to mark the tests as urgent for the lab as I was running short on time for repair. I got the report back in 2 days and Rich emailed it to me and also called me up to let me know that the results are in. I am very happy with the services he provided and will go to him again if needed

It was actually for my aunt's house, not for my own home. It was an individual, he came in and took some air samples of where the affected areas where and took some outdoor air samples as a comparison to indicate that there was more in the house than what occurs naturally outside. We just kind of had to take his word on what the results were. I thought he was very good.

Description of Work: He checked both bathrooms for moisture under the floor and in the walls. He found a suspected leak of the shower valve in the wall of the hall bath. He took samples of the air quality in two bedrooms and sent them to a testing lab for analysis.

Richard was simply great. Our kids loved him and he was able to work even with our four-year-old shadowing him and asking him what he was doing. He identified several issues that could be corrected inexpensively and quickly. (Our house is apparently way more humid indoors than we realized.) Most of the intial recommendations centered on improving ventilation and removing moisture from the air. He clearly explained how the moisture was accumulating in certain areas of the house and reassured us that even if more invasive treatment were warranted, it would cost far less than we feared. He is very knowledgeable, a good listener and has a very reassuring manner about him. I wish I had called him months ago and I would recommend him to anyone.
Description of Work: Richard came to our house on a weekend morning so we could avoid needing to schedule later. I told him about our issue briefly over the phone and when I advised him that our kids' room was an affected area, he seemed duly concerned and recommended coming out sooner. He took samples of indoor and outdoor air, inspected our house, checked wall tempuratures and looked for moisture in the walls and advised us of ways we could remedy the moisture in our home that was causing the mold.

Rich is very professional, thorough and responsive. We were forced out of our house due to a highly toxic mold situation. Rich conducted the tests over the weekend and got us the results as soon as possible. He also helped us mediate a difficult situation with the provider. I would definitely highly recommend Rich.

Everything went fine. He was an enjoyable person and he was very thorough. So we enjoyed it. Luckily we didn’t have any problems and so that made it even better. There were no additional services. He didn’t find any problems and everything looked good. The price was a real good deal.

My first concern was that this company is located approximately 5 hours from my home. Next, over several days, I was provided with the names and eventually telephone numbers of four individuals that were going to call me (within hours) to schedule the appointment. As of this writing no one has contacted me to confirm a scheduled date. I do not appreciate what has transpired thus far and do not care to continue with this company. Please provide the refund. Thank you.

Not good at all. First, he charged me $450 which I later found out other service providers will do the inspection for free. Second, his recommendation was to "repair the leak in the shower". So, I called a plumber and took time off from work. There was no leak. I ended up not only wasting my time, and the plumber's time, but paying $200 to have a hole put in the wall. I then had to have the drywall put back in, sealed, and repainted. It did not look the same. The plumber went into the crawlspace to look for the "mushroom growth" that was indicated in Richard's report. The plumber did not see such evidence; and spoke on the phone with Richard about it. Richard then back peddled and said he had a picture of one small mushroom. Richard said he could not believe that his testing equipment and report were incorrect about the leak in the shower. He offered to help pay for the expense. Only he did not. Instead, he came over and provided the test again...this time for "free" "at his cost." He never reimbursed for my out of pocket expenses for $200 for the plumber as he promised. Richard also recommended pasteurization from his favorite referral partner, PW Stevens. This cost me over $2500. I later found out from a real estate agent that it was her experience that these don't need to be done as there is always evidence of mVoc in the air. So, Richard made money for himself and his referral partner and provided suspect recommendations. Call someone who does the test for free.
Description of Work: He did show up on time, was courteous, and professional dressed. He performed a moisture inspection ($150)and air quality lab tests ($340). Angie Discount $40.

MY BAD! This project was completed over a year ago and we have not heard from this member since the pasteurization was completed and certified. I am very sorry they were left with so much anger, of course if I were promised something which was not delivered I would be upset to. In reviewing the project, I do remember making that promise and have as of 5/3/14, sent the member the reimbursement My characterization of the project is that we resolved the members’ issue of mold in their rental and all liability that comes with it. The tenant in fact moved out of the rental complaining of mold of which the lab report clearly substantiated. In 2013 the member contacted Richard Gray CMI, CMR, CRIE. and with the help of affiliate members of Certified-environmental the problem was resolved which allowed the member to re-rent the property with no further risk of liability. All of which was done at a fraction of the cost of conventional mold remediation thanks to pasteurization.

Rich and his daughter Jayce were great. Very nice people, very diligent, and prompt. They checked the walls for moisture and did all the required mold testing. And Rich told me what his nose was telling him?that he didn't smell any mold. The test results, which came just two days later, backed him up. It's one of those businesses where you hope you never need anybody, but when you do, you want to deal with people as nice and competent as Rich and Jayce.
