Radon Mitigation Pictures
The Good (our radon mitigation systems)
Following you will see some radon mitigation pictures some from systems we installed and some I have come across in home inspections or service calls and a couple I found on the web. All of our systems and any good radon mitigation system will incorporate proper design and skilled installation of high quality materials. This makes for a safe, long lasting and efficient system that requires almost no maintenance. Aesthetics, including the placement of the system components, also play a role.

Below we take a four inch vent pipe for this mitigation system up through the soffit and terminate above the roof surface. Alternatively the pipe could have been routed out and around the large overhanging soffit and then up in front of the gutter but that would not have looked as nice.
We strive to make every installation as cosmetically acceptable as possible with in the given budget. For example, can you spot the radon mitigation system in the radon mitigation picture below?
Answer: No, because it is hidden from street view by placing the fan and vent pipe behind the chimney. We always try to use a chimney, or bush or mechanical equipment like an air conditioning unit to help conceal the radon system as much as possible.
The Bad (dangerous stuff we've seen)
In this radon mitigation picture the radon vent is in an unsafe location right on a deck where people could be standing. Any radon vent should always be at least 10 feet above ground and never where people could be sitting or standing. The air exhausted from this vent pipe may have extremely high radon levels many times that of what the indoor radon level was prior to system installation.
The fan in the radon mitigation picture seen below is mounted inside the living area of the home, specifically, in the basement. This is not safe because if the fan or any fitting inside the house: 1. develops a leak, 2. comes apart or 3. is damaged, this fan could pump extremely high levels of radon into the house. This would cause radon gas levels to be many times higher than before the system was even installed. All radon fans should be installed in non-living areas, such as attics or on the exterior of the home.
See our page on "Testing for Radon" before redoing your radon mitigation system
And The Ugly
Exhibit A: if you look closely, you can see black mildew growing on the wall above the vent pipe due to the moist air blown on it from the pipe. The air pulled from under the basement floor by the radon fan can have high amounts of moisture (up to several gallons a day). This vent should have either a 45 degree fitting to direct the air away from the home or it should extend above the roof line.We shortened the pipe and put a 45 degree fitting on to direct the air flow out away from the wall and soffit.
VERSUS: HOW IT SHOULD HAVE BEEN INSTALLED... see the radon mitigation picture below and notice the 45 degree angle on the top of the pipe to direct the air out away from the wall and soffit to prevent mildew, peeling paint etc.
Exhibit B: NOT SURE WHAT THIS EVEN IS? It is a radon fan mounted horizontally, (not proper and voids any factory warranty) which can allow moisture to pool in the bottom of the fan casing and could damage the fan. The vent is plastic insulated duct designed for a furnace, totally unsuitable for a radon vent, and attached with electrical tape. Nothing about this installation is safe or permanent or comes close to meeting the EPA's set of radon mitigation standards.
In the following radon mitigation picture you can see the condition of the plastic vent that was removed from the radon fan mentioned above. This vent will not hold the radon gas very well and is not a safe vent material even if it was not torn.
Exhibit C: Here a furnace heat duct booster fan was used to vent radon gas using a dryer vent. This fan housing is not designed for radon and is not air tight in any way. This dryer duct is not safe or in any way suitable for radon mitigation. I can only surmise that it was used because it's price was a fraction of the cost of a real radon fan.
Some of these radon mitigation pictures are illustrative of how the current radon mitigation landscape is a lot like the wild west centuries ago. Lawlessness and every man out for himself; you never know what you might come across. In the early days of radon mitigation (1980's and early 1990's) there were no real standards. In December 1991, EPA published "Interim Radon Mitigation Standards" as initial guidelines for evaluating the performance of radon mitigation contractors and serves as the basis for the more detailed and final Mitigation Standards that have been developed subsequently. Even today however, most states have no specific regulation or oversight for proper installation of radon mitigation systems. Hence, "Buyer be-ware".
As with any job that needs to be done, it helps to have the right tools and experience or a knowledgeable guide and instruction to help get you through.

Over the years I have received help and instruction from many people in many places. This web site is under construction in an ongoing effort to try and put as much information and help in one place to make it easier for others looking for radon instruction, radon information or radon resources to help with all needs radon related.
