Everything You Need to Know About Interior Systems

Wednesday, June 29th, 2022 by Evan Schmitt

A great option that we provide to our customers is for the system to run entirely on the inside of the house. It keeps the aesthetics of the home and it can often last longer than an outside install!

In an exterior system, we would run the pipe along the side of the house and then exhaust above the roof line. However with the interior version, we would for example run the pipe out of the basement, into the garage and then up into the attic, which is where we would put the fan. The only part you would see on the outside, is 12 inches of the exhaust pipe on the roof, which we paint the color of the shingles.

Interior systems often last longer because the fan isn’t exposed to the elements nearly as much as outside. There isn’t rain and moisture on it frequently and the sun’s UV rays aren’t baking it. These can lead the fan to last for a couple more years, especially if the customer also gets our moisture guard which makes most of the condensation and rain bypass the fan. Also the fact that 99% of the system is inside the warm house makes freeze up less common in the winter at the exhaust point.

Though an exterior system is more expensive than a traditional radon install, there can be a lot of benefits to the customer including aesthetics, lifetime of the system, and noise.

I hope that we have given you the information to make an informed decision for your mitigation system!
