The radon fan can be installed on the outside of the home. We take care to make the system as inconspicuous as possible. The exhaust is upgraded to 4” diameter PVC and the fan raised to reduce the backpressure. Two 45 degree elbows are used to provide the safest radon levels and reduce the potential for freeze-ups in the winter. -

Exterior single-story building with transition fitting. If you like the appearance of the transition fitting, we try to install the transition fitting as long as the following is true: masonry exterior and the vertical structural member (that will support the riser) is within ¾”. -
Based on our extensive experience, we highly recommend using PVC pipe as the exterior exhaust pipe over aluminum downspout for the following reasons: PVC is a better insulator so the system will be quieter and there will be less chance of the system freezing up in the winter. Allows complete sealing of seams so there will be no leaking of radon or condensation and no chance for mold growth. This photo shows the PVC exterior exhaust pipe painted to match the home for a more aesthetic look. -
This home’s Home Owner’s Association wanted the system to be located on the backside of the home. We were very creative in our solution to meet the HOA’s requirements. This is a picture of the exterior exhaust with the fan underneath the deck and exhaust running along the downspout on the rear of the house. -
exhaust pipe,Exterior Fan Installation,radon exhaust,radon mitigation,thermal imaging,thermal imaging cameraWe use a thermal imaging camera to identify the location of the exterior studs to properly fasten the exterior exhaust. Why is this important? This extra step ensures the quietest system that will not fall apart even in the strongest winds. These extra steps provide the safest system so that the exhaust does not fall down and hurt someone or damage the house when there is severe weather. Why do we do all the extra work? Because our clients are worth it. We are always making improvements in the safety and longevity of our systems so that we can better serve our client for many years to come. -
This picture shows why aluminum downspout isn’t a good solution as PVC pipe for the exterior exhaust pipe. Downspout can leak air and moisture at the seams. This photo shows mold growth at one of the seams. If downspout is used, it should be sealed at all the seams. Otherwise, radon gas and moisture will be illegally discharged. -
This photo shows how we attach the exhaust to keep the fasteners and pipe as straight as possible, eliminating any unnecessary bends and turns, improving efficiency and aesthetics. The brick and siding was not even, so to properly fasten the exhaust a spacer was used to bring out the exhaust an inch to seamlessly flow from the brick to the lap siding. Yes, this extra care takes time but lasts a lifetime. This extra care is what our clients receive and deserve.
