Equipments for homes with a crawl area, no gravel under the piece (typical in older homes), or an entirely finished cellar, reduced level, a garage attic installment, and so on may cost even more. Radon can not be seen, scented, really felt, or otherwise discovered, apart from with an examination. That's why, according to the EPA, the only way to know for certain if you have a radon trouble is to test. This approach uses suction points that are drilled in the subslab (usually four to 6 inch openings that appear like hollow pits).
