home inspection, basement waterproofing, air duct cleaning, dryer vent cleaning
+ 2 moreThey are definitely at the high end from a price perspective, but I think that the quality and professionalism supports this price. We now have the Cadillac of crawl spaces and no mold in our ducts. We would definitely use them again when we need to get our ducts cleaned. Excellent job!!
Description of Work: We contracted to have them fix a problem with moisture in our crawl space (waterproofing and insulation) and cleaning our air ducts. During the cleaning we determined that the air ducts need to be replaced and they did this work.

home inspection, insulation, basement waterproofing, air duct cleaning, energy audit
+ 3 moreFrom 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.
Description of Work: 1. Cleaned and sealed crawl space. Removed mold from wood and sealed it. Insulated perimeter walls with expanding foam and foil-foam-foil insulation. Laid a moisture barrier on crawl-space floor. Sealed duct joints with expanding foam. Insulated crawl-space door and attached secure latches. Sealed crawl-space external vents and installed a furnace filter. 2. Reamed and cleaned downstairs air ducts from furnace to registers, and cleaned cold air return. Applied mold inhibitor to the ductliners. 3. Installed radiant barrier on attic floor and knee walls, adding insulation above finished bedroom over garage. Put an insulating flip cover over attic access ladder. Installed insulating lamp covers over recessed-lighting cans.

Employees were friendly and responsive, however did not explore fully the water's path before quoting an estimate and doing the work. It wasn't until they were nearly finished with the 2nd floor remediation that I asked the question "if it came this far, shouldn't we also check the 1st floor and crawl space?" They admitted the oversight, and when they checked, found that both of these areas had damage as well. We ended up needing to schedule another visit to treat these areas, and incurred the additional expense as well. Overall I think the job was adequate (though one can never truly be sure when treated areas are largely unseen!), but I would advise diligently following the work to be sure nothing is overlooked.
Description of Work: Attic furnace had been leaking for some time before it became evident to us, causing wood rot and mildew along its path.

insulation, air duct cleaning
+ 0 moreEmploying Indoor Environmental Systems, Inc. for this multi-faceted 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, Miquel's work crew made the best of the situation. The crew of 5 demonstrated teamwork at it's 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 accomodate 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.!
Description of Work: This project included an initial, thorough inspection by Green Building Inspector, Scott Jansen. He explained all of our options after his assessment of the property. We opted for cleaning all the air ducts including supplies, returns, supply registers, return grills, and the coil. The main trunk was brushed and vacuumed. Mold remediation of the ductliner including a painting of the metal ducts with an anti-microbial coating was included. Throughout this process, a HEPA air scrubber was operational, cleaning the air. The 2nd phase of the project was creating a closed conditioned crawl space. (Air sealed, clean, dry, energy efficient, mold and insect free.) This included air sealing the perimeter walls with expanding foam, covering the ground and walls with radiant barrier insulation and ventilating the crawl space and living area with a fresh air venilation system. Again, the HEPA scrubber was used during this phase. All existing insulation was removed from the crawl space as well as the ground moisture barrier. Mold was removed from flooring, ducts, plumbing lines and hanging wires were secured. CleanSeal was applied to wood surfaces. 150mil thick moisture, radon and insulating radiant barrier ground cover was installed. The perimeter wall was sealed and insulated with fire resistant expanding insulation foam. A foil/foam/foil insulation was installed on perimeter walls and a crawl space supply vent with backflow damper was installed, also. The 3rd phase of the project involved some energy-saving measures. Radiant barrier insulation was wrapped around the water heater and an attic ladder radiant barrier cover was put in place.

energy audit
+ -1 moreDid not hire IES but hired another company. ADDENDUM ****On 3/17/11 I was pleasantly surprised to receive a refund of my evaluation which I think was excellent customer service. I did not request the refund, but it must be that my report of Angie's prompted them to "make things right" with me since they did not meet my expectations with the evaluation. Therefore, I am changing my overall evaluation to fair.
Description of Work: I did not use IES. I was expecting a better energy audit since I had to pay for the evaulation ($125). I was hoping for a blower door test to show all the areas of leaks. All the $125 got me was a walk thru and a minimum look through an attic skuttle (unlike another company whose owner went through the skuttle and into the attic walking and crawling to thoroughly investigate). He found holes in the construction that I was unaware of. IES was proposing to install radiant barrier. The quote was prohibitively expensive. The main thing that irritated me was paying $125 for the evaluation, which I was not charged by two other companies.

basement waterproofing
+ -1 moreOriginal quote and visit was very encouraging, however, the person who did our estimate left the company and the new project manager neglected to do a site visit before sending the crew out to perform the work - resulted in quite a few communication and specification discrepancies. The new project manager and on-site crew did do an amazing job of trying to make it right, but overall experience was a little frustrating. Could have gone smoother. Did do very clean work, but would likely investigate other companies if I were to require the same service in the future.

heating & air conditioning/hvac, insulation, air duct cleaning
+ 1 moreThe 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 breath 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 be happier!
Description of Work: This company did a complete crawl space remediation and duct cleaning service on our house. The experience with this company was outstanding from the first visit by their salesman to the final visit by their work crew. The job started on time and was completed on schedule and there were no additional costs beyond their original proposal. This is the first company I found to be completely competent and well managed. It was an informative and great experience. The salesman, the company’s owners and even the work crew all had great patience in explaining the processes they performed and to answer all questions. They also did follow up during the work and even after the job was completed.

insulation
+ -1 moreScott Jansen scheduled an appointment at our convenience, was prompt, efficient & professional. He talked to us about some of our insulation issues and explained the extensive services IES provides. He had a quote to us the next day, which included applying CleanSeal in crawl space- a non-toxic, clear, odorless, antimicrobial coating with lifetime warrantee against microbial growth. The CleanSeal was $385. Insulation batts were $2,002, and attic radiant barrier cover was $325. We were also eligible for a Senior discount of approx 10%. We decided to forgo the CleanSeal as our crawlspace is very dry. Also, we went with another quote for insulation that was about 50% less. We did, however, have the radiant barrier installed, and are very pleased. I believe it will save significantly in energy costs. The installer was AJ, who scheduled a time at our convenience. He was very polite and professional. He did have to come back one more time to finish the job, but that was no problem. Again, he came at our convenience and was professional and quick. He did an great job and also cleaned up extremely well both times. What impressed me most about Scott and IES is that they didn't "loose their cool" because they lost the insulation bid. They maintained a positive, eager, professional attitude and were every bit as responsive to my calls and questions, even though this was a small job for them. I definitely intend to consider them strongly when we're ready to re-insulate our attic, which will be a bigger job.
Description of Work: We wanted R-19 insulation batts installed in our crawlspace, aprox 1400 sq ft. We also wanted a cover for our leaky attic access door.

With their help we were able to sell the home. They were very responsive and timely. I couldn't ask for better service.
Description of Work: They did mold remediation, applied clean seal, and covered the crawl space. It was not a total encapsulation, but they partially encapsulated the crawlspace. The crawlspace was encapsulated up to ground level. It reduced the humidity tremendously. They installed a dehumidifier and a pump to keep the humidity down. They also bricked over one of the foundation vents to prevent water penetration.

They did an excellent job for the mold remediation. They did run into challenges for the finished work; they had to remove some of the drywall where the mold was and replace it. The quality of the repair work on the drywall was very bad. We had to call them back out to do further work on the drywall. After they came out the second time I had to personally go and do some more sanding and finish work in order to give it a more decent finish. For the actual mold remediation the quality of work and the cleanliness was excellent. It was just for finished work and the repair on the wall that they need further training. The clean up was very good; I couldn?t tell that they were there.
Description of Work: Indoor Environmental Systems Inc did mold remediation for us. They also did the air ventilation system treatment.

basement waterproofing, air duct cleaning
+ 0 moreI used IES to take care of my crawlspace. We needed some mold remediation, as well as a new moisture barriers and insulation. They also cleaned our vents. However, during the work they damaged the freon line to my air conditioner causing it to all leak out. I had to spend $400 on a service call to Bolton for new coolant. IES eventually reimbursed me, but only after a couple hours of arguing. They also installed an option that I did not want, and did not agree to, and only one of the crew at my house spoke english passably. The mold remediation, moisture barrier, and insulation look amazing. The Bolton repair man even commented on how good it looked in my crawlspace. They did a great job installing the stuff and cleaning down there, but the secretary that sets up the contracts seems a little disorganized and it was frustrating that I had to argue with them to get them to reimburse me for the AC repair.

basement waterproofing
+ -1 moreI 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.
