Spent the last year testing radon, received two quotes to remediate the radon! First quote stated that due to the size of the crawlspace approx. 1200 sq ft ((2ft average ht) several rooms due to previous owner add-ons)) we would need to draintile the whole area and might need 1 - 2 systems ($6000+). Another business stated that a radon system or two was not cost effective and recommended sealing the sump pump and adding a air system to vent air into and out of the basement. After and air system was installed the radon went down by half. It was then recommended to seal the crawlspace. We have two options...Crawl space encapsulation, neurocrete, or concrete crawlspace sealing? Who has any experience with any of these products? Moisture has not been an issue...we have a couple cracks in the outside concrete block...only issue...mice...we have cats! We are close to the water so it is damp frequently.
