Full systems with polyurea plus spray foam and a dehumidifier commonly run $8,000 to $20,000+.

How long does crawl space encapsulation take?

One widely cited planning estimate says encapsulation usually takes three to five days once prep is complete.

Ask the pro to confirm your project meets current code.

How long does an encapsulated crawl space last?

Full systems with polyurea plus spray foam and a dehumidifier can last 25 to 30+ years, according to an encapsulation guide. That long service life is one reason the upfront cost ranges higher than basic liner-only systems. Compare liner-only and full-system options in your quotes.
