What Is a Crawl Space Encapsulation Cost Calculator?
A crawl space encapsulation cost calculator provides quick and personalized cost estimates based on your crawl space’s size, condition, and material preferences. It simplifies budgeting by breaking down expenses for insulation, vapor barriers, drainage systems, and optional dehumidifiers.
By using this tool, you can explore various scenarios and make informed investment decisions for your home.
Detailed Cost Components
Crawl Space Insulation Cost
Insulation materials like spray foam or fiberglass vary in price. Spray foam is more effective but costs an extra $1 to $3 per square foot.
Crawl Space Vapor Barrier Cost
A polyethylene vapor barrier typically costs $2–$4 per sq. ft. Thicker barriers last longer and resist moisture more effectively.
Cost to Seal Crawl Space Vents
Sealing vents costs between $150 and $450 and improves encapsulation integrity by blocking outdoor moisture.
Crawl Space Drainage System Cost
A drainage setup—including sump pumps or drain tiles—costs between $500 and $4,000, essential in wet environments.
Dehumidifier Cost for Crawl Space
Expect $800–$1,600 for a high-efficiency dehumidifier. It maintains optimal humidity even after sealing.
