"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."

"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!"

"Fernando was very accommodating when scheduling both the initial meeting to provide an estimate and to work on the job. He arrived promptly both times and his quote was on target and did not deviate after the job was completed. The area of the basement wasn't completely cleared for him to start work when he and his son arrived, but he even helped to move things. Both of them kept things neat and clean, which made it easy for them to clear out quicker with no mess for us to pick up after. I'm picky about installation and didn't want the utility side of the house to look like an industrial area, so Fernando was able to install the exhaust up to the roof alongside the downspout. He also answered any questions on his the written proposal and his price was as stated for the work that was needed for my particular job. We needed 2 locations in the basement floor where they had to install PVC pipe to draw out the radon to a single fan attached to the outside of the house, that exhausted up to the roof. Really clean install. Also got another test kit from him, so that we can test for basement radon levels within the next 2 weeks to see if levels have been reduced to below the maximum allowed. Fernando said he will come back should we need any adjustments and advised us to remember to call him for annual service. His company is listed by the CT Dept of Health as one of the few qualified radon mitigation professionals as of July 21, 2016 - there's only a total of 6 qualified in Fairfield County, so that's definitely a positive sign that we selected the right guy for our job."

"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 Brewster, 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.
