Radon Testing in Brandon, SD
Call (605) 210-7667 Brandon is 9 miles from Sioux Falls. You hear back from a person, not an autoresponder, within one business day. Call before 3pm on a weekday and it is usually the same afternoon.
Two reasons Brandon homeowners call for a test. Either a purchase agreement is running and the mail-in kit will not come back in time, or the house has had a system for years and nobody has verified it since the day it went in. Both are 48-hour jobs with a continuous monitor.
What we see in Brandon
Brandon's housing is uniform enough that the readings cluster, and the pattern that shows up is elevation near Split Rock Creek where the till thins over the quartzite. Houses on the older streets by Split Rock Park and McHardy Park frequently read higher than the newer subdivisions off Aspen Boulevard, which surprises people who assume older means safer.
Practical notes for Brandon homeowners
If there is no deadline, order a free kit from the state first. South Dakota DANR gives away 500 a year and it costs you postage. Continuous monitoring is for closings, disputes and post-mitigation verification, not for satisfying ordinary curiosity.
Radon Testing in Brandon: the technical part
Closed-house conditions are where most Brandon tests go wrong, and it is nearly always the garage door. On these builds the basement stair or the mechanical room often connects to an attached garage, and a garage door standing open for an hour during a 48-hour test changes the pressure relationship across the slab enough to move the reading. Keep it shut and keep the house shut.
What the job looks like in Brandon
The monitor goes in the lowest livable level, on a stand rather than the floor, away from the furnace return and away from the hopper window. We log the start time, you keep windows and exterior doors closed for 12 hours beforehand and throughout, and we collect it on the third day. The report comes back with the hourly trace and the average, printed and emailed.
How Brandon houses are built
The overwhelming majority of Brandon housing went up between 1995 and 2015, which means poured concrete walls, a full basement, drain tile to a sump crock and a slab that was almost never sealed at the cold joint. That is the single most mitigable foundation type there is.
Brandon radon questions
Can I run the air conditioning during the test?
Yes, on normal recirculating settings. Not on a fresh-air or economiser setting, which brings outside air in and dilutes the reading into something that does not describe how the house normally sits.
How fast can you get a result for a closing?
Device in on day one, out on day three, signed report the same day it comes out. That fits most inspection periods, but call early rather than on the last day of the window.
