“Busy, Busy” (Late Spring) vs. “Not So Much” (Early January)
If you assume that most radon remediation is done pursuant to housing transactions — specifically, the Buyer’s home inspection — it’s easy to predict the peaks and troughs in radon contractors’ workload:
Step #1: determine when the most and least housing deals get done.
At least in Minnesota, for peaks, it’s predictably mid-April to mid-May. For valleys, it’s invariably the end of December.
Step #2: add 10-15 days. That’s how long it usually takes for Buyers and Sellers to: a) resolve inspection issues, including elevated radon (over 4.0 picoliters per million parts, or pCi/l); and b) for the Seller to follow up, assuming the parties agree that the Seller will take care of it.
In other words . . . right about now is a very good time to line up a radon contractor, particularly for homeowners who have no intention of selling, but simply want a safer home.
Depending on the home’s size and existing HVAC, the cost should be around $1,500 (whether the system is passive or active is another factor).
