In real estate transactions a lot of buyers ask for the home they are purchasing to be tested for radon gas prior to the purchase. This beautiful home in Door County tested high for radon gas and A-1 installed the radon mitigation system so the new owners would feel safe. Any questions about radon testing or mitigation give me a call direct to discuss. Adam 920 639-6542 cell 262 977 7799. We service the entire state of Wisconsin.
