Moisture Barrier Installation Costs for Professionals

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 $1.75 to $3.25 per square foot. For a 1,000 sq ft crawl space, this translates to $1,750 to $3,250. 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.

Labor Costs and Considerations
