              Indoor Environmental Management installed French drains for me recently. From the beginning the plan was well conceived, carefully thinking out the solution to my wet basement and how to implement a solution. The teams doing the work were headed by Justino and Carlos who did a competent, thorough and perfectly executed job. They were very reliable and I highly recommend them. Excellence is how to describe the whole process. Susan

    Customer Testimonial

              I am a very satisfied customer of Indoor Environmental Mgmt. John Hassler and the entire team were true professionals. They went above and beyond to insure that our crawl space concerns were addressed. He (John) took ownership of the problem which gave us confidence that the remedy (encapsulation and structural) would be done the right way even if it exceeded the original quote. Additionally, our job was completed ahead of the schedule and I have never seen such a hard working implementation crew as Carlos's team. Everyone we dealt with at IEM was responsive and professional.

    Donald G. of Tallahassee, FL

    Customer Testimonial

              It was about a year after we bought our house we started to notice flooding in the basement. On a consistent basis whenever it would rain back to back we would get about an inch and half to two inches of rain and then it would slowly go away. Then after one very heavy rain the basement had about 7 or 8 inches of standing water; you can see the line on the basement walls. It was finally time to call a professional. We first reached out to the previous owner of the home to see if they recommended anyone, and they gave us Mr. Hassler’s name. We also met with other groups and did some research. When we did a walk thru with Mr. Hassler I was more than pleased with his outstanding knowledge and historical data of the problems. He not only knew some ideas of where the problem could be coming from, but he also knew information regarding the rain patterns. Apparently when the house was built there was not as much rain as we get now. He explained that the detailing of the house needs to be updated for the upper trending of rain in our region. I was very pleased to have him on board. At the beginning of the project, Mr. Hassler gave me a quote for the entire job. Not one time did he ever change that quote or add expenses that were not discussed with me prior. I thought that was very honorable, and would love a chance to work with him again, but hopefully we won’t need his help or services! At first I was nervous about the pump because of the amount of water, I wasn’t sure if it would work. We turned it on during a super heavy rain and it worked like a charm. The basement already feels drier. Mr. Hassler is such a great guy, I have already referred him and Indoor Environmental Management to my neighbors and co-workers.

    John L. of Tallahassee, FL

    Customer Testimonial

              When John L. was trying to sell his Tallahassee. FL home. a home inspector told him that the fiberglass insulation that was once installed in the crawl space, between the floor joists was in really bad shape and under such conditions, it was impossible to make a proper assessment. John L. had insulation removed and a second inspection revealed even more problems: there was mold and dry rot was beginning to compromise the structure. The high humidity was causing condensation and water was dripping from the air ducts onto the floor, creating puddles on top of a newly installed moisture barrier. In an attempt to find someone to fix these problems, John called several contractors. HVAC companies. Indoor Environmental Management and another area company that provides crawl space encapsulation services. "Only Indoor Environmental. not only said they would cover all of the basics: fixing the wood rot, fixing the moisture. the duct work, and basically cleaning it all up. They were also going to guarantee it for the future." -- explains John. "Going with Indoor Environmental, everything was finished, everything was done, the price was definitely better than having each thing done separately. So I can't recommend them anymore than that!"
