Travis and Critical Environment responded quickly. Called me back right away on a Sunday morning. He did a job for me earlier this year and had an issue come up while that job was under warranty still. He took care of the problem no questions asked standing behind the warranty.

If you’re looking for a pro to help you with mold issues, I can’t recommend SGS enough. When I discovered the toxic effects mold was having on my health, I couldn’t believe it. I researched and did my homework to understand mold and how to effectively remediate. I was shocked to find that I knew more than most “mold restoration” companies out there and how unregulated it is in Michigan. I sought out true professionals and that’s how I found SGS. They know their stuff, go above and beyond, communicate effectively and efficiently, take the necessary steps, and have helped us through home inspections and remediation support. I wouldn’t trust anyone else. SGS services were higher in cost but that’s because they actually do what is needed to remediate the problem and not make the problem worse like many companies do (which end up costing more in the long run and have health consequences). I’m so grateful that SGS does what they do!

We received verbal confirmation that our asbestos test was negative for the ceiling tile samples but have not received the written lab report yet (2 weeks). This is a minor complaint as i am sure they will mail it to us

Scott Fisher and his team are exceptional! They went the extra mile in helping me remediate a home that was in poor condition. They were informative and positively engaged and were communicating with me regularly on our progress. I would highly recommend SGS to anyone who needs help in the Environmental Testing and Contracting space.

Morgan called back on memorial day which I was shocked about. Was able to come by and collect the samples the next day. Results came back in 5 business days. Very professional, great overall experience.

We experienced a bit of sticker shock at the cost but, how do you put a price on the health and well being of your family? All associates were friendly, extremely helpful, and courteous to a fault. Morgan and Scott were over and above helpful and answered all our questions. I would recommend this company to anyone.

Morgan and his team at SGS were very patient and understanding with me and my questions. They took their time to ensure my family and I have a safe enviornment to live in. They also gave me tips on how to keep the mold from growing and becoming a problem again. They were all so very friendly and professional and I will definitely hire them again for any future needs!!

We contacted SGS in December in order to determine the cause of excessive dust in our house emanating from our heating/AC ductwork and remedy the situation. This has been an ongoing issue that was not corrected by duct cleaning. They came out within a couple of days completely focused on the idea that we had a mold problem and took some samples. Testing showed that mold was not the issue and we were told that the Fresh Air Return was probably insufficient. We were told that they could connect us with someone who could determine what was needed. After multiple inquiries, they have been unable to find anyone to help us. We spent a lot of money for a few test samples and lab reports, with absolutely no plan to fix our dust problem.
