FAQ

Vapor Barrier Installation Questions We Hear Every Week

What mil thickness do I need for my crawl space?

Most residential spaces do well with 12-15 mil; heavier foot traffic or storage use often calls for 20 mil for durability.

Can you repair a damaged vapor barrier instead of replacing it?

We inspect the full barrier during the visit to make that call honestly.

Do you wrap support piers and posts?

Yes, pier and post wrapping is included in a proper crawl space vapor barrier installation, since unwrapped supports are a common moisture bypass.

Is a vapor barrier the same as full encapsulation?

We can scope either depending on your budget and how severe the existing moisture issue is.

How long does vapor barrier installation take?

Most standard-size crawl spaces or basements are completed in a single visit.

Will a vapor barrier alone fix my musty basement smell?

It often helps significantly, especially if ground moisture was the primary source, though persistent odors may point to an additional issue worth investigating.
