Fiberglass & Mold Remediation – Myth # 6

In today's post, we're gonna talk about the myth of leaving the insulation in place between the joists when removing mold. Is this a good idea?

Crawl Space Insulation

We get a lot, a lot, a lot of homeowners that tell us that the crawl space contractor that was there three days ago looking at their crawl space says that they're going to leave all of the fiberglass or Rockwool insulation up between the floor joists whenever they address the mold.

We think that is a big no-no! How in the world do you know if there's any mold back behind the insulation on the subfloor? And if there is, how can your mold treatment get behind the insulation in order to properly disinfect it?

When you leave the subfloor insulation up, all you're able to properly treat is the exposed joist, not the subfloor or the remaining joist that's covered by the insulation.

Crawl Space Mold Removal - The Right Way

What we do is take all the insulation out. All of it. We pull it down, bag it up, and completely dispose of it. That way we can see what's behind it and properly disinfect any mold. That is the best way to handle it.

If somebody tells you that they're gonna leave the insulation in place to address mold, they're only really addressing a few inches of the wood that's sticking out from underneath the insulation.

So we call that a myth. We don't wanna leave the insulation in place when addressing mold and if your contractor has, you might wanna get another opinion.

Remember that proper mold remediation is just one of the steps before crawl space encapsulation. Check out all of our services to see how we can help you get started on your crawl space project.
