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 back pressure. Two 45 degree elbows are used to provide the safest radon levels and reduce the potential for freeze-ups in the winter.

The radon system exhaust pipe must extend up the side of the house so that radon is exhausted above the highest eave of the home. Here the exterior pipe is neatly installed behind the fireplace chimney.

This exterior system is hidden behind a fireplace and tucked behind the AC condensing unit.

The two extra rubber couplings near the fan provide optimum efficiency and noise reduction. NEW! We now offer white rubber couplings for a clean look!

Our proven state-of-the-art noise reduction techniques are now available! This includes 4" PVC exhaust pipe and 2 additional rubber couplings that help to isolate and eliminate vibration noise transfer. Also included are mechanical pipe supports (not pictured) that are wrapped with rubber to isolate the noise. The fan is raised to reduce back pressure inside the system.

An on/off switch is installed within 4' of the radon fan and in view. The electrical and pipe penetrations are sealed with caulk to make water tight.

Based on our extensive experience, we highly recommend using PVC pipe as the exterior exhaust pipe over aluminum dowspout 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.

Supports were extended to eliminate any unnecessary bends in the system to reduce noise and increase performance and safety.

Due to the beautiful but uneven flagstone surface, a threaded rod was used to extend out and support the exhaust pipe.

Our client wanted to hide the system and go through the first soffit. In this picture the system goes through the first soffit and around the second rear soffit.

This is how the exterior exhaust pipe may look if you have a mansard style roof.

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.

We 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 improvement in safety and longevity of our systems so that we can better serve our client for many years to come.

This photo shows an optional exterior fan housing that encloses the in-line vacuum fan. This housing can be painted. Installation of this housing is an additional charge.

This picture shows why aluminum downspout isn't a good solution as PVC pipe for the exterior exahaust 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.
Exterior Fan Installation,radon fan,radon mitigation

There will be an on/off switch within 4 feet of the fan. It should always be "on".
Exterior Fan Installation,noise reduction,radon mitigation,vibration collar

We are the only contractor making improvements on reducing the radon system noise by installing vibration collars on the exhaust pipe support system.

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.
Exterior Fan Installation

To prevent unnecessary bends in the pipe, which would increase back-pressure, a threaded rod is used to attach the exhaust to the house. It also helps the exhaust withstand severe weather. Having these fasteners allow our team to provide a professional product.

For this home we installed the exhaust pipe through the roof instead of going around the soffit to protect the architectural features of the home.
