radon crawl space cost can sneak up on you, especially if encapsulation and venting aren't done right. I've seen estimates from a few hundred for a simple fan setup to a couple thousand for full sub-membrane depressurization, including labor and sealing. The trick is getting a proper radon test first, because if levels are high, you're not just paying for peace of mind, you're preventing serious health risks down the line.
