"I had a fantastic experience with Greene Solutions! Every point of contact was professional, from office associates to the company's owner. I own an old house (100 years old) with knob-and-tube wiring. That old wiring threw a spanner in the works, i.e., the old wiring had to come out in order to install insulation. I had a devil of a time finding an electrical company to do this job. Finally I called Greene Solution's owner (I was in tears) and said I was giving up; no one would do the job. He told me he'd try to find a company while I was vacationing in VT. Well, when I got back, he'd located a company and my contacts with that company (Brett Short Circuits) were completely satisfactory. There were several phases to my project, and all went splendidly. The solar attic fan was installed and I'm very pleased. Basement ductwork was sealed (Aeroseal). My goodness! Positive results were immediate: I moved one entire category higher in efficient usage with both the gas and electric companies! The old attic insulation was removed before the electrical work started. Greene Solutions did this attic cleaning. What a dirty job! Given the age of my house, the workers had to contend with a mega-buildup of old coal dust. Yuck! The electrical company (Brett Short Circuits) then did the rewiring of my entire house. This was a huge job and I was completely satisfied with their work. The team of electricians assigned to my job was excellent, extremely hard workers. They were very conscientious about cleaning before they left each evening. They used canvas drop cloths to cover my furniture as they moved from room to room. Finally, they kept me entirely 'in the loop' re their schedules. I appreciated their courteous and respectful attitudes. Their work was approved and signed off on immediately by city inspectors. New wiring in place, the project then moved to the insulation phase of the project. Greene Solutions did this phase of the project. It took two days to get this job done. Attic, walls, and basement were insulated. This was another hugely dirty job, given the old coal dust in my house. For those of you who don't have experience with coal dust ... thank your lucky stars. It gets into everything (even wood grain) and it stays. This particular phase of the project took two days. I was very pleased with Greene Solution's team of workers. They were courteous, respectful of my space, and were heads-down workers. Another great team! Door installation awaits delivery of the doors. Of course, all had to be custom-made, given the age of my house. Greene Solutions will do this phase of the project and I anticipate no problems. I highly recommend Greene Solutions. I am very pleased with the partnership we forged as I took steps towards reducing my carbon footprint."

"Very well! Josh was very informative and professional. I was a little nervous about using a company based solely off of other people’s opinions but I was more than impressed! I would certainly recommend By-Lyons."

"Do not use Kustom Home Inspection for your home inspection. We utilized the company in July of 2020 to inspect a home we were in contract for. There were multiple instances where the inspector was not thorough, and or, utilized an excuse to not inspect further. For example, the inspection report stated, "Sump pump was not accessible for testing due to being sealed for radon mitigation system." The house is sealed for radon, but the sump pump is easily accessible by removing an unsecured cover. Shame on me for not inquiring further, but isn't that what I paid them $400 for?"

"I found that the home I had just bought in December of 2023 was tested and recorded a radon level of 40 piCu/l [micrograms of radon gas in a litre of air]. The safe level recommended is to be below 4 piCu/l. This was an unfortunate set back on an expensive investment. I was very concerned with getting the radon level down to safe livable level when I contacted Radon Systems. After talking with Lucas I was somewhat assured that they could mitigate the radon gas from its current levels down to below the acceptable 4 piCu/l and maybe even exceed reading. I was worried about them not being able to accomplish this and asked Lucas the "What if" question. He assured me that they could expand the system to get there if the after action test showed the level was still to high. "We've mitigated houses with levels in the hundreds" he said. I contracted with them to start within two weeks. After the mitigation my level was recorded as 0.8 !!!!!! I am so happy and satisfied with the installation and the results. THANK YOU Lucas and David! Great to work with and lots of professional integrity. Ken"

FAQs for radon gas abatement projects in Delaware, OH

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.
