If I could I would give this company 0 stars. They are not honest and totally misrepresent their work in a highly unethical, illegal manner. They utilize fear mongering sales tactics to rope you in and charge astronomical prices for work that they do (in reality don't do). They are very good at this shady sales tactic.
We contracted with Indoor Environmental Systems (IES) for several projects and ended paying almost $100,000 when all was said and done. Because of the issues we have experienced as detailed below, I am going to utilize an independent inspector to review all of the work that IES has done for us to make sure the rest is legit, safe and performed as contracts indicate.
One of the projects was for 'Closed Crawl Space Repairs'. The scope of work detailed: Ground & foundation walls covered using insulation liner; Foam/foil (150mil) radiant barrier - Provides moisture, radon & temperature control.
The main intent for these repairs was to eliminate (at the least reduce) radon. The IES salesman indicated that their process will 'most likely eliminate the radon completely' but that there was a small chance it would not and in that case we would need to contact a radon mitigation company.
The completed work had zero impact on the radon levels, so I reached out to a radon mitigation company. They came and did their inspection and informed me the product used by IES is not safe for crawlspaces and does nothing to help with the control of radon. Not only is it highly flammable (they showed me by holding a lighter up to the material and it instantly combusted) but is also against building code ASTE E1745-11 CLASS A, B, C.
I contacted IES with this information and was provided with a link to a general product page https://www.insulation4less.com/house-insulation-stop-cold-moisture-air-and-heat by the owner Stephen McLeoud. Nowhere on this page, or any of the specific product detail pages is there any mention of radon, let alone being able to control radon as the scope of work indicates.
In a very poor attempt to further divert from being held responsible/liable, Mr. McLeoud also sent me this link: https://www.insulation4less.com/installing-insulation/how-to-insulate-a-crawl-space. He stated, "When reviewing the HOW TO INSULATE A CRAWL SPACE refer to Benefits of Prodex Total Insulation In Crawlspaces, find #7 which states radon resistant." This link talks about sealing the ceiling with the product that was used, however our ceiling wasn't sealed. And using Prodex Total Under Concrete for the floors, which wasn't used on our project and is specific for being used under concrete slabs. Therefore, the statement of being radon resistant is false.
Important to note that I tried contacting insulation4less.com (sole distributor of the product used) multiple times over several days to get feedback from them. It went straight to some sketch voicemail every time and I have yet to receive any call back. I even tried to contact the product manufacturer and their phone number is disconnected, and their is no email address on the website. Crazy... read more
