Odor soaking into original subfloor and framing
Why it happens here
Many Bessemer and Minnequa homes still have original hardwood over a crawlspace with no vapor barrier. Fluid wicks into the wood and stays there, and surface treatment does not reach it. Warm weather makes it worse.
Our approach
We map contamination with moisture and ATP meters, remove affected subfloor sections, and treat the framing with hospital-grade disinfectant. Then we run hydroxyl generators for 24 to 48 hours and verify before we finish.
