Andover lies east of Wichita along US-54/400 (Kellogg), across the line in Butler County. Many of its neighborhoods were built with full basements, often finished as family rooms, offices or guest bedrooms. Because radon readings are usually highest at the lowest level of a house, those finished basements are exactly where Andover families should test.
Same state rules, different county
Being in Butler County doesn't change the rules. Kansas law requires anyone who tests or mitigates radon for someone else to hold KDHE certification, wherever in the state the home is. For test kits, the K-State Research and Extension office for Butler County is the closest extension source, and kits are also sold at hardware stores and online.
Homeowners' associations and the pipe route
A radon system has a visible part: a PVC pipe and a fan that vent soil gas above the roofline. Many Andover subdivisions have covenants about what can be added to the outside of a home, so check before you sign a quote. You usually have three route options:
- Exterior: pipe runs up an outside wall, usually on a side or back elevation. Simplest and often cheapest, but the one most likely to need HOA approval. It can often be painted to match the siding.
- Through the garage: the suction point is in the basement or garage slab and the pipe rises inside the garage and out through the roof. A popular compromise in attached-garage homes.
- Interior: the pipe runs up through a closet or chase to the attic, with the fan in the attic. Least visible from the street, usually the most expensive.
Ask the installer for a simple sketch of the route and exhaust point you can send to your association if needed.
Working around a finished basement
In a finished basement, the installer looks for a spot that doesn't disturb living space: an unfinished utility or mechanical room, under the stairs, or the sump area. They'll also seal accessible cracks and the sump lid. If you're planning to finish a basement, test and install first; it's much easier to place a pipe before the drywall goes up.
After installation
Check the U-tube manometer on the pipe now and then; it shows the fan is pulling suction. Retest within 30 days of install, then every two years, as the EPA recommends. See radon fan care and replacement.
Request a quote with your ZIP code and a note about your HOA or finished basement, and one KDHE-certified professional serving Andover will follow up.
Common questions
Will my Andover HOA allow an outdoor radon pipe?
It depends on your covenants. Many associations allow it if the pipe is on a side or rear wall and painted to match. Ask before installation, and ask the installer about a garage or interior route if an outside pipe is not allowed.
Is a KDHE certification valid in Butler County?
Yes. KDHE certification is statewide. Any Kansas-certified radon mitigation professional can legally work in Andover.
Should I test before finishing my basement?
Yes. Test before you finish it. If the level is high, installing the system before walls go up keeps the pipe out of sight and usually costs less.
