Understanding the Cost of Installing a Moisture Barrier

For construction professionals, installing a moisture barrier is crucial for maintaining structural integrity and indoor air quality. The cost can vary significantly based on several factors. In the Dallas-Fort Worth area, the average cost ranges from $1.35–$2.00 per sq ft per square foot. For a 1,000 sq ft crawl space, this translates to $1,350 to $2,000. However, factors such as labor availability, material type, and site conditions can influence the final cost by up to 40%.

Key Cost Factors in Moisture Barrier Installation

Material Type: Options range from basic 6-mil polyethylene to 20-mil reinforced films.
Crawl-Space Size: Larger areas increase material and labor costs.
Access and Clearance: Tight spaces require more time and specialized tools.
Seaming and Sealing: Proper sealing adds labor hours.
Preparation Work: Includes mold remediation and debris removal.
Insulation Upgrades: Often paired with moisture barriers.
Permits: Some areas require inspections and fees.

Material Options and Current Prices

Stay updated with real-time pricing for materials:

6-mil poly sheeting: $0.15–$0.50 per sq ft
12-mil reinforced barrier: $0.70–$1.25 per sq ft
20-mil premium barrier: $1.50–$2.00+ per sq ft

Labor Costs and Considerations

Labor accounts for 55-70% of project costs. Standard access allows for 200-250 sq ft per installer per day, while limited access reduces this to 80-120 sq ft. Current labor rates in the Metroplex are $30–$100 per hour.
