Radon Action Plan
+ Cost Calculator
Start with the situation you are in right now, then open the county plan that matches it.
The goal is simple: decide whether to test, retest, budget mitigation, or turn the result into a buyer/seller number without bouncing between generic articles.
Path 2
I need to test first
Use the testing guide if you do not have a confirmed reading yet. It covers kit choice, placement, timing, and when it is still too early to price mitigation.
What to buy
Short-term kit first, then a monitor only if you need ongoing tracking.
Where to place it
Lowest livable level, under closed-house conditions, before you worry about quotes.
When to price
Only after you have a real number or a repeated borderline reading.
Decision first
Use one page to decide whether to test, retest, budget mitigation, or turn the result into a repair number.
Local price anchor
County-level receipt logic keeps the number grounded before you ever talk to a contractor or seller.
Transaction ready
Buying and selling paths stay inside the same flow instead of forcing you into a separate generic article.
