"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.

"Very pleased, not only because the professional services, but also truely fully insured business. Many contractors only carry liability insurance, which might be the minimum requirement to be listed in HomeAdvisor, but in real world, it's necessary to have Worker's comp and E&O. I'm very glad Supra has them all, and send me the copy of the certificate insurance before doing the job. Highly recommended."

"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.

FAQs for radon gas abatement projects in Larchmont, 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.
