Description
Crawl Space Science: What to Have Done and WhyBy: Larry Janesky There is no shred of evidence or science that says vented dirt crawl spaces make sense and tons of evidence, right before our eyes, that says they are a serious problem. Yet over 250,000 new homes and thousands of additions are built each year with dirt crawl spaces. There are now 26 million of them. The building code not only allows dirt crawl spaces, but actually made the problem much worse by requiring them to be vented.
