I contacted St. John’s Environmental to inspect and test suspected Aspestos in a building I planned to demolish. They came out within a couple days and I received the test results and a full report by the next business day. Thanks to these guys help, I was able to satisfy all requirements for DNR and assure that everyone involved in the demolition is safe from hazardous materials. The cost for their services were very reasonable compared to other companies who wanted to charge much more and would not have been able to conduct the inspection for weeks.
Ian and his team were very professional. I called for their help and they arrived the next day to support us. 5 stars are not enough - I’d give 10 if I could!
At 22 weeks pregnant with my first child our older home was being remodeled exposing previous layers of paint. We decided to purchase lead test strips off Amazon that came back positive. I frantically called Ian on a Friday night and he responded instantly and had someone at my home first thing Monday morning. With their state of the art equipment they tested all areas of concern that came back negative! It is very clear to me that this business is ethical and cares for families while also being experts in what they do. The at home test kits are not reliable and I wish I would’ve saved myself the panic and found this company first. Thank you to both Ian and John again!
I don’t know that I could say enough about this guy. I called as a panicked momma, and he answered all of my questions before knowing if I would be a customer or not. Truly, truly a wonderful person. He never made me feel rushed or like I was overreacting. I couldn’t have expected to get someone so nice and caring. This is your guy! You’re lucky to live near him!!
