Mold & Toxic Material Test - For Business
Travis, who was amazing, came out to test my residence. He was early, down to earth, and professional. He reassured me that I was not crazy, that he could tell after 10 minutes of being in my apartment that I had a mold issue. Travis continued his testing, which was very detailed, efficient, yet a quick process. My tests were sent in for lab testing and it came back as positive for mold throughout my apartment. Travis and the team at Critical Environment helped me prove that my residence was the cause of my illness and was the proof I needed to get my lease terminated. This was an absolute answer to my prayers. In my opinion, there is no better company to test your home than Critical Environment. A month after Travis tested my place a client of mine was complaining about health issues, I told them about my experience with critical environment. They called and Travis came out the NEXT DAY and tested. You will not find a more professional and proficient company than CE.

Mold & Toxic Material Test
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.

Mold & Toxic Material Test
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

I left a voice mail message for this company at 2 a.m. on a Sunday morning. I had a phone call from them at 8:00 a.m. on that same day! They stayed in touch with me and from beginning to end, we are very pleased with this company!

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.
Response from

"We came out and did our mold test but discovered she had a dust issue that we tested as well due to a lack of fresh air coming into her HVAC system. I did explain to Peggy that adding a fresh air intake to her HVAC system was a bit outside of our wheelhouse but we would try to find a good HVAC company to fix her issue. Unfortunately, we could not get find anyone we knew willing to travel down to Muskegon. I called her back and told her about our dilemma but that we had a team member that has great HVAC experience that would be willing to come over at (no charge) to review her system and come up with a suggested fix and quote on us adding a fresh air intake. Peggy decided not to take me up on the offer. We wish Peggy and her Husban well and hope they find the help they need."
