"Lance and his crew showed up right on time, explained clearly what they were going to do, and answered all of my questions. After the installation was completed, they cleaned everything up, so there was nothing I needed to do afterwards. I realize that every house is different, and radon mitigation results will vary from house to house. Also, my house had ideal conditions for a good radon mitigation outcome - a 4 inch gravel bed under a basement concrete slab with no cracks or other places radon gas could enter from below. Having said that, my radon levels before mitigation averaged 4-6 pCi/L, with occasional peaks to 10-12 pCi/L on some days. After mitigation, the levels have been below 1.0 pCi/L since installation 2 weeks ago. Needless to say, I am very pleased with the result. I would not hesitate to recommend Lance and his crew for any work you might need for your home."

"Paul cam to assess the mold on my basement walls and he didn't just come in a look. He went above what we thought he'd do and inspect the baseboard in the entire basement. He also checked oitsode to see where the moisture could be coming in from. He was very efficient and helpful with providing information on air filters, remediation, and potential causes and how to prevent. We would use him again."
Ground water infiltration occurred through the concrete slab in two rooms on the ground floor of the house causing water damage and mold growth on the overlying flooring. The cause of the water infiltration appears to be associated with cracks and a crater in the concrete slab, which is believed to have been caused by pile driving work being performed during the construction of an adjacent building.
Mold in HVAC Coil Compartment
Construction/demolition work in an  apartment unavoidably released high levels of dust that migrated into adjacent apartments. Dust containment methods, such as negative air filtration and poly sheeting, should have been used to prevent dust migration into adjoining spaces. Settled dust samples were collected from a table & curtain rod in a nearby apt, which revealed the presence of substantially elevated levels of silica and asbestos in the dust. Asbestos and silica are known carcinogens.

"Fernando answered my call and was at my house the same day. I had a 19 year old radon mitigation system in place, but I had not had it inspected since I first purchased the house. The basement which was normally never used for other than a laundry room was to become a teen hangout/crash pad. I read that it should be inspected every few years and Fernando confirmed that. I wanted to make sure that the system was working properly before turning this space over to kids. Luckily, the fan was still working all those years later. He replaced the pipe outside of the house with PVC and extended it past the gutters and roof. He also replaced another tube like/straw that I forgot what it was called. All in all, Fernando was prompt, attentive, and knowledgeable. I did mention to him that I may have my roof replaced and he gave me some tips so that no roofing debris will fall in the pipe while they're working. I feel confident that if I need to contact him again, he will be as prompt and diligent as our first meeting. Thank you!"

"Andy from Poseidon Home Inspections provided us with an extremely thorough examination of our home.  He was more than punctual, arriving early and starting his survey before we arrived.  We went through every single nook and cranny of this property from the roof to the basement, and at every step of the way Andy explained what he was looking for, why he was looking for it, and how each system of the home was supposed to operate. <br /> As first time home buyers purchasing a home with unfamiliar amenities (well water, septic, etc.) we are pretty green and we needed to have a lot of the information presented to us in layman's terms.  Andy understood this and was extremely patient, making sure we had a firm grasp of the condition of the various aspects of the property before moving on.  The entire inspection took more than three hours for a 4000 square foot home on 1.3 acres of land. The report he provided us was equally as thorough. <br /> His assessments were accurate, unbiased, and came with recommendations for companies to contract to alleviate some of the issues.  It was also clearly stated that Poseidon Home Inspections worked for us, and that no information would be shared with a third party without our consent.  Most importantly Andy made and continues to make himself available to us to answer any questions that we have even weeks after the inspection.   <br /> Poseidon Home Inspections has become a valuable resource for us as we settle into our new home.  We whole heartedly recommend this company. <br />"

"House: Mid 1800s farmhouse, approximately 4000 square feet Inspection Components: General home inspection, plus termite, radon, well water, and septic tests Time to complete: approximately 3 hours. Inspection report was provided the same day and other tests came in a week and a half later. Inspector (Chuck): Was responsive and and accommodating for scheduling the inspection. He arrived early on the day of inspection to begin his prep work. Chuck took his time to explain the inspection process and walk us through each part of the home. He gave us detailed overviews of similar homes and potential issues, then explained how this home compared. He also helped explain how the mechanics of the house work and how to operate components of it effectively. Quality: As far as we can tell, Chuck's inspection was very thorough. He pointed out a number of issues and look his time to triage and assess potential problems. His equipment is top notch, and includes a drone for roof shots and a thermal camera for assessing the heating system and finding heat leaks. He collaborated well with a second septic inspector we had on site and even found a minor plumbing leak in the basement that had previously been undetected. Value: For the size of this home and quality of his service, Chuck was a great value. His price includes a discount for finding him via Angie's List. Summary: I recommend Chuck based on his service. Chuck arrived early, was detail oriented, and provided a high quality report. Other reviews on Angie's List seem to be accurate reflections of his work. I did have to send him a reminder e-mail to get our well and radon results although Chuck responded back with the results very quickly. This was around the holidays so, considering, that minor delay was understandable and not a big deal."

"My house had excessive levels of radon in our lower level. The Lance Dorfi team installed a pump to pump out the radon and release it up above the roof of the house. Since then, radon levels in that part of the house have been very low, so the problem was resolved. The work was done on budget, and they did an excellent job with scheduling and customer service. I recommend them for dealing with radon."

FAQs for radon gas abatement projects in New Rochelle, 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.
