"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.

"Amazing! Fernando was really helpful. He looked at our job, and helped us navigate an erroneous elevated radon level due to the weather. He saved us in a situation where we would have spent a thousand without solving anything. Thank you. Your guidance and engagement was very helpful."

"I would recommend Poseidon Home Inspections to anyone looking at property in Westchester. Andy was excellent and very thorough. He has clearly been deeply involved at all levels of house ownership which truest shows through in his work. Especially as a first time home buyer, Andy will reveal any and all details about the house you need to know about. Even my realtor was blown away by his level of detail and care. Cannot recommend Poseidon Home Inspections enough. This service was expensive, but wow, was it worth it. We now have a 5-10year financial plan for home upgrades and maintenance which aligns to all the inspection findings."

"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."

"Lance made the whole process seamless and worry-free. From discovery of my homes elevated radon levels through system installation and completion of post-installation testing I felt that I was in good hands at all times. The cost of work was competitive with other quotes I requested, but the personal attention and responsiveness I received was truly the most valuable part of my experience. It was also welcome to find a company that values innovation and stays current with latest technology. No other company I spoke with offered a rapid testing alternative with time-based readings of my homes recorded radon levels. Thank you Lance for putting my family back to ease."

FAQs for radon gas abatement projects in Yonkers, 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.
