Top notch amazing company!! Julio was super knowledgeable, professional and pleasure to work with. I highly recommend this company!! I had the test results back in 2 days. Julio has since been helpful answering any questions I had! Look no where else if you need an indoor environment specialist.

It was a breath of fresh air to deal with someone as competent, pleasant and honest as Julio. He came to our residence to test the air quality in our basement following a leak...we were afraid of mold. He was thorough in his explanations and so helpful giving us suggestions and advice.
Professionalism, knowledge and patience that's Julio. We were so pleased with his services and would recommend him in a heartbeat!

I had a very excellent conversation when I was desperate to have an independent advice on possible mold. Julio was terrific, his input allowed me to walk away from an offer.

Julio - the public face of OIES - is a very patient and knowledgable man! We needed help after we found mold in the basement. He visited us on a number of occasions before we finally committed to ultimately more work than we originally envisaged. The work entailed taking air samples, extensive removal of drywall, insulation, framing, carpet and subfloor, followed by mold removal, scrubbing and cleaning. As well as more work in other places, HEPA filters and more. A lot of work was performed in a week while we were on vacation!
We received updates and pictures and were fully consulted and informed before we moved back into the house. Now, the house is clean and will allow us to move on with renovations. Thank you!

I asked Julio of OIES to come out and do an estimate and mold test, and he seemed very knowledgeable and patiently answered all my questions. Of the 3 contractors I had an estimate from, OIES gave me the best feeling. The did the work during a week in March, and Julio's team worked hard and carefully. I was able to work concurrently on other attic upgrades and they even assisted me for part of it. I am very satisfied with the results and would not hesitate to hire them again.

We found OIES to be a company that is excelent at their work and in ensuring high customer satisfaction. Julio came to our house, found and explained the mold situation very well. Their work over two days was impeccable and their attention to detail was astounding. They went over and above the call of duty and they cared! We are really satisfied customers. We highly recommend them .

Hello, I met Julio from the OIES Team during a crisis situation. I had been issued a stop worker order and needed a quick turnaround to obtain a Designated Substance Report (DSR). Julio was there the same evening and he carefully went over the sample collection requirements with me and went about his business. He expedited the sample lab analyses and provided his report in 48 hours. His fees were very reasonable however what impressed me the most was his kindness and professionalism. I wish I would have consulted him earlier so that he could have gone over the Ministry of Labour requirement with me at the onset of the project. Julio knows his stuff and can provide you with excellent advice on how to handle and dispose of asbestos or other substances if some are found, although in my case, it wasn't needed as I had an abatement done earlier. I highly recommend the OIES Team for your renovation projects.

When we bought a house that needed work, we called OIES for some testing for asbestos. They were quick to respond, and walked through the house with me to point out which materials could have asbestos and should be tested, and which were safe -- great education and peace of mind, especially since I was doing a lot of the renovations myself. They gave advice on what I could safely work on, where I should take precautions, and what needed to be dealt with by professionals. Their lab work was quick, and the prices less than other labs we had contacted. Very professional throughout. I highly recommend OIES if you have any suspicions about potential asbestos in your home.

I hired Julio as a newly built studio apartment in the basement of my house was growing mold. The mold started once we turned off the heat at the beginning of the summer. I hired Julio based on some of the reviews that I read on HomeStars as this was something totally new for me. Our appointment was booked on a timely schedule for both of us and Julio was professional in every way during the process. I appreciated the fact that Julio took the time to discuss the process and answered all of my questions. The report that Julio gave me afterwards was easy to understand and I wouldn’t hesitate to recommend Julio to others.

I hired Julio to test for asbestos in our 1920s house. He was very accommodating to our schedule and arrived exactly when he promised. I appreciated the advice he gave for the amount of samples to take and he did very clean work. The report was finished on the date he promised and fortunately for us, our walls were asbestos free.
