"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."

"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."

"After a home inspection I was told that I needed to <br /> remediate a ?black substance? aka mold from the roof of my attic crawl space. <br /> The black stain covered most of the plywood and some rafters. I was told it was <br /> probably due to poor ventilation. <br /> I had less than two months to remediate before closing. This <br /> was a first for me so knowing where to begin and who to call was the most <br /> difficult decision to make. Not many people talk about mold in their home so <br /> finding a contractor was going to be a challenge. <br /> I went right to Angieslist and started looking and I came <br /> across Enzyme Life Sciences. I read the many reviews and saw pictures from one <br /> customer who had the same issue I had. There were before and after pictures of <br /> the job performed. I thought if my roof sheathing could look like that I would be happy. <br /> So I called and talked to Mike Partlow who understood my problem and he talked <br /> me through three part process of cleaning the mold and removing the stain. Mike <br /> is out in Albany but has trained contractors throughout the NYS region so being <br /> in Buffalo was not an issue. I talked with a few other contractors and some <br /> were either booked for the next few months or were on vacation ? (during <br /> December). Ultimately, I decided to go with Enzymes Life Sciences and I?m so <br /> glad I did. Within a week, Mike sent out a gentleman named Scott who cleansed <br /> the mold from the attic. The attic looked clean as promised. Mike also gives a <br /> 5 year warranty that is transferrable to the new owners which was very <br /> advantageous when adding it to the amended home contract with the buyers. <br /> Mike also stuck with me after the job checking in with me to make <br /> sure the sale was going through with the cleansing completed. That's one other thing <br /> to look for when shopping for a contractor; Mike is there for you and stands behind his work. <br /> Finally, the house closed on schedule within a few days of the final inspection. <br /> I can?t say enough about Enzyme Life Sciences, if you need to get rid of any <br /> mold in your home Mike is your guy. <br />"

"John did a full inspection of the condo unit and produced a 16-page, highly detailed report. Ninety percent of the information in the report was something that I would have never thought to ask. I took his recommendations for repairs and submitted them to the seller with a request to fix the problems. John was very professional and knowledgeable. I would highly recommend his services."

FAQs for radon gas abatement projects in Hartsdale, 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.
