    Great guy to work with. We needed our well water tested prior to selling. Had our results on time as promised! Thanks!

    I hired this company to mitigate radon in my 1950s home, which has clay soil under the slab and an…read moreinterior French drain system around the basement. In my opinion, they did very little investigation before starting the job. Their first attempt was simply installing a sub-slab suction point without tying into the French drain system at all. They left a monitor for a few days, and the radon levels did not change. About a month later, they came back and added another suction point. This time, they ran piping across the basement to tie into part of the French drain system. The frustrating part is that there were easier access points near the original system, including the sump area or the channel leading into the sump, that could have been evaluated first. Again, they left the monitor for a few days, and the radon levels still did not change. Another month later, they returned and added a 2nd sub-slab suction point in the center of the basement. Still no real improvement. At that point, they told me I needed to seal cracks around the basement, so I did. That also did not fix the problem. Their next suggestion was to stack two fans to increase suction. I did not feel comfortable with that approach. I felt it made more sense to use a properly sized higher-suction fan rather than stacking fans and hoping for the best. Eventually, I decided to stop using this company and troubleshoot the issue myself. During that process, I discovered they had only tied into half of my French drain system. My house actually has two separate French drain sections, which they never identified. Once I added a suction point into the second French drain system and upgraded to a higher-pressure fan with good airflow, the system finally started working the way it should. My setup is now basically a hybrid system: three sub-slab suction points and two French drain suction points. In hindsight, I believe if both French drain systems had been properly investigated and tied in from the beginning, some of the extra sub-slab work may not have been necessary. Overall, my biggest frustration is that there did not seem to be a real diagnostic process. It felt like they were guessing, waiting weeks between visits, and hoping the numbers would eventually drop during warmer weather. But radon is often worse in the winter because of stack effect, so a temporary drop in summer does not necessarily mean the problem is fixed. Based on my experience, I would not recommend this company for a difficult radon mitigation situation, especially in an older home with interior French drains and clay soil. If the house was built with gravel under the slab, they would probably do great. However, my experience with them has been terrible . So terrible that I had to figure this out on my own. If I could give them 0 stars, I would.

    I would not recommend Airtech to anyone. I bought a house with an Airtech system in it, and when…read morelevels were going up, I called AirTech and they told me that another fan need to be added to the system. That didn't help. With levels high, they refused to come out quickly and I had to get another company to come in to evaluate the problem. The other company said there were obvious problems with the system that should have been corrected. Then on the day before the scheduled AirTech appointment, AirTech refused to come out unless I told them what extra work was going to be done, or they would not drive out to my house because it didn't make "business sense".

    Insulwise team was professional and thorough, and completed the project on time. We had our attic…read moreand part of the garage insulated in October, in time for the frigid winter weather. We have yet to see any energy savings, as promised on their website. Taking weather changes into account which was about 25% colder so far, we also used about 25% more gas to heat the home at the same settings. On the plus side, the room above the garage and second floor bedroom below the attic are more comfortable and less drafty, so we 'll keep tabs and hopefully we'll see better results in the summer with a/c usage.

    We had our house insulated this past year, but I didn't want to leave a review until the cold…read moreweather came. And, today, January 28, 2026, it has come. And the results of the work done by Insulwise is now clear. In the past, we could feel the cold coming right through our walls which meant putting on additional clothing even as we turned the thermostat up. That is no longer the case. Strikingly, we can touch the inside walls, facing the outside of the house, and not feel the cold at all. There are no longer cold spots in the house that we avoid. We have turned down the thermostat and still the house is much warmer than it was last winter when it wasn't nearly as cold outside. My daughter and son-in-law noticed the change immediately when they visited and commented on it. In summary, the work done by Insulwise did exactly what we had hoped for. In terms of economics, we are in our 70's and may or may not be here long enough to recoup the savings on our heating bills. But we are so much more comfortable now than we were in past years that we will never regret getting this done; our only regret is not getting it done sooner. Thank you so much, Insulwise!
