Crawl Space Repair Photo Album: Bad Odors from Salem, OR Crawlspace

The homeowner called sought help from John's Waterproofing because she felt like her house smelled a little 'fishy' and she didn't know why. She thought that it might be coming from dead rodents that had gotten into the crawlspace. She was not wrong that the smell was coming from her crawlspace, and upon inspection, we found evidence of rodents and water intrusion. The odors that Karen was smelling was caused by something called the 'Stack Effect'. This means that the house acts as a vacuum from the roof by pulling up air from the foundation and bringing into the living space. 50% of the air that is in the crawlspace is entering into the first floor, which means that whatever is in the crawlspace is being breathed in by the homeowner.
