We have foundation vents, kind of!

Recommended Posts

When I pulled up to inspect this home the AHJ was just leaving from issuing the CO.

Do you see anything wrong with the foundation vents from inside the crawlspace? Better yet, do you even see the foundation vent!

Educate me Scott, what is that plastic doing? Besides blocking the vent. Is it under the sill plate? Looks like it's stretched tight.

I asked the same question to the builder. He said that it is to keep moisture from wicking up into the sill plate. Yes, the sill is treated wood.

I had a termite guy tell me that some builders put the plastic down so that when the CMU is insulated with spray-on cellulose or foam they can come back and remove the plastic and have a clean 6-8" line with no insulation.

Honestly, I do not see any good reason for it. Old school before treated wood was to keep the moisture out of the sill plate.
