"First he was late, approximately 15 minutes late, which was disappointing since I understand now that many inspectors arrive a little early so that they can finish looking at the perimeter of the house. He had my realtor, my husband and me waiting after we rushed from work. He was also late when picking up the radon test when my realtor was waiting for him.
Overall, Mr. Polo knows his stuff. He spoke very knowledgeably about things. He also went under the deck to do a good oil tank sweep even though he said he usually doesn't do that. So I give him credit for thoroughness in that regard. In the end, if you just want a guy who will walk through the house, point out stuff you need to pay attention to while you take notes, then he's your guy. But if you are a first-time homebuyer and need someone who will do more hand-holding, show you how to turn off the water main, and stuff like that for example, or give you a really detailed report with pictures and arrows, then Mr. Polo is not the one for you. I learned this the hard way, but due to time constraints I couldn't get the inspector I originally wanted. Mr. Polo though accommodated my schedule, but in the end his services fell short.  His report is almost incomprehensible. There are unfinished sentences and no pictures, but he does get it to you quickly.  So if time is a factor that's another reason to hire him. But like I said, if you're a new homebuyer and need the report as a reference for future fixes and are not good at jotting notes during the inspection, then I would recommend going elsewhere if possible.

"A two-man team worked very efficiently to remove each vent cover and vacuum inside the vent openings throughout the townhouse. One man removed the vent covers while the other man vacuumed inside the vent openings. No problems with how they worked but I think there are other companies who perform a more thorough cleaning of ductwork using other methods. This company did a superficial cleaning and worked very quickly. In and out within an hour.

"What a surprisingly wonderful experience we had with BioClean. I was able to schedule a same day appointment, and Brian and Dennis showed up exactly on time. Both men are absolute professionals, and are extremely honest! Within minutes of entering the home, they measured the air for particulates, and said that it wasn't a high reading at all. They proceeded to test around our home, and also up in the attic where the air handler is. The thought to look in places we never would have thought to look, but they said everything was actually in good condition. We did figure out that there is moisture in the basement coming from what may be a leaky toilet on the main floor - which we never would have known. The took their time, were very thorough, and made no money from us (with the free estimate coupon they posted here on Angie's List). They could have told us anything, and we would have believed it (and probably paid through the nose). But - these guys truly are wonderful, honest, and professional. If we have more work to do after the plumber comes to fix the leak, we will DEFINITELY call them to do the work. On a scale of 1 to 10, they are a 43."

"As a realtor, I found Rich from Expedient Environmental Solutions while searching for a client who needed mold remediation. He and his crew did an excellent job at a fair price. They finished on time and left the home clean. So, when I was looking personally to have basement waterproofing (interior french drains and sump pump) along with radon mitigation, I received 3 quotes, of which theirs was the most comprehensive plan, and again not the highest quote overall. They finished the work ahead of schedule by bringing four workers the second day, were respectful throughout and left the area reasonably clean. I'm confident that my days (and nights!) with the shopvac and flooded basement are finally over, and grateful they stand behind their work for a full year. Good contractors are hard to find. Glad I found them. Thanks and I highly recommend!"

FAQs for radon gas abatement projects in South Salem, NY

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
