What our satisfied customers are saying about us:

"From beginning to end the experience was positive. Scott's estimate was in the middle of the estimate pack, and the way he presented the prospective work was clear and convincing. He also was available for telephoned questions before we finally chose IES. An additional reason for our choice was the distinctiveness of Scott's proposals, appropriate materials and installation procedures for the different parts of the job. Scott also worked with us on a price we could afford. Within one week of our accepting the estimate, Miguel and his crew showed up on the appointed day. They worked steadily and efficiently, finishing the entire job in less than two full days. Miguel then went over all the different steps, explaining how each was done. The day after the work was done I asked Scott to inspect it with me; even though this was not usual procedure he came right over and we looked at all the work, again with his full explanation. I'm glad I don't have reseal the crawl space or insulate the attic again, but if I did I would choose IES."

"The quality of the job was superb and we couldn't have asked for anything better. We had a person out to do work on our furnace and they said it was the best crawlspace-sealing job they had ever seen."

"Employing Indoor Environmental Systems, Inc. for this multifaceted project was an excellent decision! From the initial contract through the entire process, customer service was of paramount importance to them. Scott Jansen's initial contact with us set the stage for what would turn out to be a far better than expected experience. He was able to identify issues and convey solutions to us. By incorporating photography, he was able to help illuminate the issues at hand. His prompt turnaround of a quote, ease of contacting him, and willingness to work with our schedule were appreciated. Without having access to outside from the crawl space, Miguel’s work crew made the best of the situation. The crew of 5 demonstrated teamwork at its best! The floors were covered and the jobsite was kept clean at all times. When the job was done, the floors were vacuumed. Before leaving, the workers pitched in and moved our furniture back in place. An issue with equipment required work on another afternoon. Christina Thomas scheduled that work as soon as the part was available for the foam spraying machine. Throughout the process, she scheduled work to best accommodate us. The final paperwork, including documentation for energy credits and photographs were forwarded to us by her. From start to finish, it was a joy to work with Indoor Environmental Systems, Inc.! I would highly recommend this company!"

"From initial contact to completion this firm was very prompt, courteous, and professional. They provided references and arranged a visit to a previous customer prior to us contracting with them. Their work was completed on time and the work team who installed the product was courteous, efficient, and very respectful of our home and property to assure nothing was damaged. They have followed up to see that we are satisfied. We would recommend IES to anyone who desires to add this level of efficiency to their home."

"The project involved the cleaning and removal all the mold and fungus located on all the wood structure under our house. Once the wood was clean, they sprayed a plastic coating on all the wood to seal it from moisture and possible reestablishment of mold.

They completely foamed the wood area above the block wall foundation around the whole perimeter of the house. The ground and walls were then lined with a 1/4th inch thick Mylar foam Radiant Shield material. The crawl space vents and all foundation penetrations were also sealed with foam. Next they installed a sophisticated air filtering system to draw outside air into our HVAC unit, eliminating bringing in crawl space air into our house. Finally, they modified our HVAC system to deliver
filtered and conditioned air to our crawl space.

One last comment. When has a contractor done some work for you and then cleaned up after themselves? Gosh, these guys not only raked, cleaned and leveled the crawl space ground before installing the radiant shield; they also picked up all debris in our yard where they staged their equipment. They even vacuumed the carpets inside our entire house!

We now have a clean, dry, insect and mold free crawl space. Fortunately, about a third of our crawl space is high enough to walk around and it is now suitable for safe and clean storage of our personal property. And, we can now breathe easy in our house knowing that our air is free of mold, fungus, pollen and other contaminants.

This company is the best! What a great job, we couldn't’t be happier!"

"I sought three proposals for this service and IES's price was competitive. Their approach to this project, however, really stood out. Compared to others, they seemed exceedingly thorough and knowledgeable, and that turned out to be the case. Their work was completely professional and their superior expertise clearly reflected in the finished product. Pride in their work was evident throughout the project. My formerly sorry crawl space looks like a clean room. They far exceeded my expectations and I feel they delivered great value. Although this may seem trivial, I must say it is symbolic of their work that a five-man crew working two full days left not a trace of litter, cigarette butts, or anything else for me to clean up."
