Mold in Crawlspace: Remediation expert says remove insulation.

[Gregory Cottarel]

Hi All,

I have mold on my crawlspace joists/beams.

I contacted CrawlSpaceNinja as a remediation expert here in NC. 

We agreed on Soda Blasting to remove mold. So, they will need to remove insulation to access all joists/floor boards.

We agreed Dehumidifier to be installed to prevent the issue from reoccurring.

I already have vapor barrier installed.

Crawl Space Ninja stated that the fiberglass blanket insulation between the joists in my crawlspace can remain removed post remediation. They said I don't need the insulation - because the DeHu will keep the temperature in the crawlspace mild, year round. 

They stated my HVAC will actually run more efficiently without insulation - because the warm crawlspace air will rise in the winter. (And cool air in summer).

Any thoughts/questions/concerns regarding before I permanently removing hundreds of dollars worth of insulation from the crawl space? Does their logic make sense?

Thank you.

Greg
