HOW TO USE IT
How to use the Crawl Space Encapsulation Cost Calculator
- 1
Measure the crawl space area in square feet.
- 2
Choose the vapor barrier and its price per sq ft.
- 3
Enter prep and labor per sq ft, then review the total.
THE MATH
Encapsulation formula
Total cost = area × (barrier price + prep & labor)Crawl space encapsulation is priced per square foot and includes the heavy-duty vapor barrier plus prep (cleaning, drainage) and installation.
PRACTICAL EXAMPLE
A 1,000 sq ft crawl space
1,000 sq ft × ($3.50/sq ft barrier + $2/sq ft prep & labor) = $5,500.
FAQ
Frequently asked questions
When should I encapsulate?
When there is moisture, mold, odors or pests. Encapsulation stops ground moisture from rising into the home and protects the floor system.
Barrier or coating?
A heavy 20-mil polyethylene barrier is the standard for floors; coatings work on walls. Most pros recommend both.
Do I need a dehumidifier?
Often yes — encapsulation alone doesn't control air moisture. A dehumidifier keeps the space dry year-round.
