Radon Mitigation Systems
Professional Home Inspection Service has been installing radon control systems in central NY since 1991. These systems are guaranteed to reduce the radon levels in your home, commercial building or school to below the EPA action level of 4.0 pC/L. One out of every three homes in our area fails a radon test. Thousands of homes in our area are now protected from elevated radon by our systems. Radon enters the home from the soil below. These systems continuously draw the radon gas out from below the home and vent the gases harmlessly into the atmosphere. Our ventilation systems have low operating costs, require minimal maintenance, and are guaranteed. A system can usually be installed with minimal disruption in the home in one day, and can be scheduled within a week or two of your call. Please call us for a free estimate.
The EPA tells us how a radon mitigation system should be installed in a document entitled Radon Mitigation Standards. These standards can be found at www.epa.gov/radon/pubs/mitstds.html These standards have been designed to ensure that the system will be safely installed, durable and effective.
If you are receiving competing bids for radon mitigation, please be aware that low-ball estimates that you may receive are achieved by omitting services such as the radon retesting necessary to verify a successful mitigation, omitting back-draft testing that assures a safe installation, omitting the "right of cancellation" without fee as required by NYS law, and most importantly, limiting any guarantee to a specific ideal set of pre-conditions, meaning that you are likely to end up paying more in the end. Contrary to some other providers, we are a NYS listed, certified Radon Mitigation Contractor. Check the NYS Health Department website.
It may be hard to picture what a radon mitigation system will look like in your home. The basic system will include white, four inch plastic pipe extending from the basement floor to the exterior of the house and terminating above the roof line. A white fully encased fan about the size of a basket ball or smaller will be mounted on the piping somewhere outside of the living space. A new less obtrusive rectangular box fan is now available for many installations. New Low Profile Radon Fan
There are basically three standard ways to run the piping from the basement to above the roof line. We can classify these three standard piping routes as 1) "through the garage", 2) "through closets" and 3) "up the exterior".
If we have provided you with a contract for radon mitigation you can compare the proposed piping route that is in the contract with those below and then click on sample photos for that type of system. Of course your system may look somewhat different from the photos and there are often several ways the piping can be run. The piping route that is detailed in your contract represents what we think may be best. If you have a preference as to where the piping is installed, by all means let us know before the installation. We will do our best to accommodate your wishes while providing a durable system.
The three most common piping routes:
Run the pipe up the basement foundation wall, through the floor joist area into the garage, up the interior wall of the garage into the attic and then through the rear roof slope. In this case the fan is mounted in the garage attic.
Run the pipe through the basement ceiling, through closets in the first and second floor (if applicable), pass into the main attic and exit via the rear roof slope. In this case the fan is mounted in the main attic. Photos of a ranch house.
Run the pipe from the basement through the floor joist area to the exterior of the house, run the piping exposed on the exterior and around the eaves to terminate above the roof line. With this option we try to put the piping on the rear of the house or some other location where the exposed piping will not be objectionable. Photos of a large cape house.

- In some homes it is necessary to pull the radon gas out of a crawlspace in order to achieve acceptable radon levels in the home. If needed, we would seal the soil in the crawlspace with a membrane such as Dura-skrim and then run our pipe from below the membrane to one of the routes described above.
