IES was fantastic from fist contact through project completion. Steve came out for the initial consult and really impressed me with his knowledge. I was also very happy that he was willing to talk technical with me. I have some experience and like to talk details, but not all providers are willing to do that. After getting our quote and making a decision to move forward, Stephanie stepped in as the project manager. She was a pleasure to work with – knowledgeable, friendly, and responsive to all my questions. She set us up with an appointment for the project and let us know approximate timing through the course of the 2-day project. Since we were replacing HVAC ducts, there would be times when the A/C wasn’t running. Plus we would need to run the fan continuously while the materials in the crawl space cured. It was very nice going into the project with accurate expectations. The crew that did the work was also wonderful. They arrived on time and did high-quality work. As someone who’s pretty handy, I was pleased with their work. Overall, we’ve been thrilled with the sealed crawl space. We no longer have moisture or mold problems. As a bonus, the house appears to be more energy efficient. We have another job spec’d out with IES for our attic spaces, and we’ll have them out as soon as we have the other constraints completed.
