Always checking and double checking everything to make sure our home was safe and radon free. Our first system was installed in the basement where they drilled into concrete and installed a system to vent outside of the house. They work they did was truly impressive and professional. Plot twist, the contractors mistakenly turned off the system so our first test was a fail, but they quickly had the system rerouted so it couldn't be turned off accidentally and followed through by retesting it. Our second smaller system was installed due to the re-test which found we needed another system to bring it down to safe levels. Janryk said this was one of a handful of times in his entire career they needed to add an additional system. They came in to take core samples around the house and discovered the other corner of the home was the highest in radon. They installed within a few hours, had another test done, and voila! Our high radon levels became trace amounts!! I feel incredibly satisfied and safe that our home is now radon-free! You couldn't meet more professional and diligent people doing high quality work. Thank you!

Janryk is one of the most professional contractors I've worked with for my house. He came to our…read morehouse, provided a quick quote, and came to install a radon abatement system shortly after. Angela is also immensely helpful with scheduling and with any issues that come up. Our house has two levels that needed abatement so Janryk installed a system on one level that connected both and pulled from both to get the radon out. The levels dropped quickly but then popped back up. So he came back, investigated, and installed a bigger fan. That also wasn't getting the levels to the point we needed but Janryk came back again and installed a supplemental system. He stands by his work, and guarantees it. He and his team are such a pleasure to work with.

All of the basics were covered: there on time, took samples carefully and from inconspicuous areas, polite, tests came back reasonably quickly, etc. I imagine that any company that wants to stay in business would meet those standards. Where Geller Labs went from perfectly competent to AMAZING is in the patience Mr. Geller displayed with answering questions. My dad had come along with me for the test, and my dad had a ton of questions informed by his own experience as a builder and with indoor air quality. Mr. Geller spoke at length, answered every question, opened up an air vent to check inside the duct work, and basically covered everything twice. Professional, patient, competent, and a genuinely nice individual. Would totally recommend Geller Labs if you've got shady stuff happening in your house and you want it professionally investigated.

I had evidence of mold in my home from testing and told Mr. Taylor that I smelled mold in the bedroom corner and the kitchen. He gave me a 34-page "bid" (estimate), which I read in full, only to find that it was entirely boilerplate and did not explain anything about the findings or proposed remediation plan or explanation of why they needed to charge $6,000 to do what he had explained to me was simply uncaulk, dehumidify, recaulk, clean the ducts, and clean the HVAC, which is about $1300 of work. I repeatedly requested a short summary of the work to do be done, only to be told that it had to be discussed instead. I called him, and he verified the scope of work I mentioned. His explanation was that it had to be done to industry standards, which included putting the house under negative pressure and doing the work all at once, so that there was no mold flying around or cross-contamination. I told him we could not afford $6,000 and would seek to do the indicated work with other contractors, which we did. The duct cleaning guy begged me not to waste my money on duct cleaning, since he'd cleaned our ducts the year before and mold does not live in ducts, but we got it done anyway, following Mr. Taylor's general work plan. Duct guy was right; it made no difference. The two issues I had identified Mr. Taylor incorrectly indicated were caused by the HVAC (bedroom) and the kitchen drips, and that once the source of water was stopped and the area dried, we wouldn't need to close up the gap in the kitchen cabinet wall. He was wrong on both counts. I continue to smell mold coming from the bedroom wall and the kitchen cabinet. I called him to ask for additional diagnostic help with the bedroom wall issue. He did not return my call. When I called the next time, he had no recollection of the service and attributed our poor results to our not having used his state-of-the-art plan, which would not have made any difference, because he misdiagnosed the two main issues. I requested his additional help, which he refused to provide.

I figured I would call around for estimates but after having Radon resolvers come out and check things and let me know how much it would be I was ready to go immediately. I had also gotten a few recommendations from other neighbors from this company so that was an added plus. After putting down our deposit they were able to come out the following week. They didn't play. They came, did the work and showed us how everything worked and we paid them the remaining balance and they left. I feel safer and happy with this company. They were very professional and went over everything prior to digging and drilling. They even had to extend the pipe due to a change in the placement and they didn't try to up charge us. We are very happy and thankful to have had them do the work. 100% recommend!!!!
