Same first question as Harrisburg: does the house already have a stack? Tea has been building steadily since the early 2000s and a lot of those homes have most of a radon system sitting unfinished inside the walls. Adding a fan and a manometer to existing pipe is the cheapest job in this trade.

What we see in Tea

The subdivisions off Heritage Parkway and Sundowner Avenue are the newest and the most likely to have passive piping. Older Tea nearer Main Avenue and the interstate at exit 73 tends to need a conventional install. Walkouts are common on the sloped lots, and a walkout with an accessible mechanical room is about the cleanest install there is.

Practical notes for Tea homeowners

Full install in Tea runs $1,100 to $1,600. Activating an existing passive stack is typically a few hundred. We will tell you which one you have during the walkthrough, and the honest answer is often the cheaper one.

Radon Mitigation Systems in Tea: the technical part

Walkouts change where the suction point goes. On a Tea walkout the lower level slab often sits at two different elevations, with the below-grade portion against the uphill wall and the at-grade portion by the patio doors. Suction applied at the shallow end has less soil above it to work against and can short-circuit to the outside air, so the point belongs in the deepest section.

What the job looks like in Tea

We start with a small test hole and a vacuum reading at two or three candidate locations before anything permanent happens. That takes twenty minutes and it decides the whole layout. Once the point is chosen, the pit is dug out under the slab, the pipe is set and sealed, cracks and the cold joint get routed and filled, and the riser goes up through the garage or a closet chase.

The ground under Tea

Tea sits west of the Big Sioux valley on flat glacial outwash and till, which drains well and moves soil gas laterally without much resistance. Good ground to build on, and good ground for radon to travel through.

Tea radon questions

Does a walkout basement have less radon than a full basement?

Not reliably. A walkout has more wall exposed to outdoor air, which helps a little, but the below-grade portion still sits on soil and the stack effect still pulls. Plenty of Tea walkouts test well over 4.0.

Can the system run through the garage instead of the house?

Usually yes, and on a Tea walkout it is often the better route. Keeps the fan noise away from bedrooms, keeps the pipe above freezing, and hides the discharge on the back of the roof.
