Radon Mitigation in Lennox, SD
Call (605) 210-7667 Lincoln County, 23 miles from Sioux Falls, population about 2,400.
Lincoln County farm town southwest of Sioux Falls with a stable, mostly older housing stock.
Why radon is a problem in Lennox
Lennox sits on the till plain between the Big Sioux and the Vermillion drainage, on deep agricultural soil. Deep soil does not mean low radon, it means the gas has a longer path and more of it accumulates before it finds one.
What Lennox housing is built like
A lot of mid-century housing with block foundations, some with partial basements over crawl space, plus farmsteads just outside town on private wells. Sealing work matters more here than in a newer town.
Older block foundations leak in more places than a poured wall does, so a Lennox system is usually more sealing and less pipe.
Who calls us from Lennox
Lennox calls are mostly older houses and mostly block foundations, which means most Lennox quotes are more sealing labour and less pipe. The other regular caller is a farmstead outside town where the well needs ruling in or out alongside the soil work.

What is particular about Lennox
The defining feature of a Lennox quote is sealing labour rather than pipe. Concrete block walls behave like a network of vertical chimneys: each core is an open column from the footing to the top of the wall, and unless the top course was capped during construction, soil gas entering at the bottom rises inside the wall and comes out through mortar joints. That is a completely separate pathway from the slab and it is why a block house costs more to mitigate than a poured-wall house of the same size.
Common questions from Lennox
Why is my quote higher than my neighbour's?
Almost always block versus poured walls. Same pipe and same fan, considerably more linear feet of joint to seal and more open cavities to cap. That is hours, not materials.
Do I need to seal the whole basement wall?
No. The top course, the wall-to-floor joint and any penetration are what matter. Sealing the full wall face does very little for radon and gets sold more often than it should.
Scheduling and travel
Twenty-three miles southwest, grouped with Tea, Harrisburg and Canton runs. Partial basements over crawl space are common enough here that we would rather see the house than price it from a phone description.
