5 STAR Review! Crawlspace Encapsulation August 2020: Enclosing your crawlspace is an investment monetarily and also healthwise. I did a lot of research of other companies, their service and products before making my decision! My final decision was to go with Indoor Environmental Systems. My decision initially was based on the non toxic products they use, the thoroughness of their initial analysis, their professional prompt follow up at all times and response to my ALL MY questions! A rare thing these days in businesses I’ve found in the Triangle! Once we settled on a date, the installation, along with follow up and their continued attention to service, detail was 110%!!! Dan, Stephanie, Miguel and the team are top notch! As a detailed person I can ONLY say good things how they planned, executed, and followed up. The team onsite always showed up on time, were super hard working, polite, concerned, positive, tidy and very conscientious about everything they did whether it was inside the house with the vents/ducts or in the crawlspace. They were a delight to have around! The porta-potty, trash bin delivery/removal was all on time and removed accordingly. I am looking forward to a huge reduction in dust , mold being sucked up into the house, along with reduced electric bills with the encapsulation, new R19 insulation etc. I look forward to a continued professional relationship with IES….and further updated reviews.
