How Much Does It Cost to Install a Vapor Barrier Under a Mobile Home in Flagstaff, Arizona?
Installing a vapor barrier under your mobile home is one of the most important steps you can take to protect your property—especially in Flagstaff, Arizona, where seasonal weather conditions can lead to moisture buildup, mold, and structural damage.
Whether you’re dealing with ground moisture during snowmelt, heavy rains in monsoon season, or just want to prevent long-term damage, a vapor barrier provides critical protection for your crawl space and home’s foundation. But how much does it cost to install one in Flagstaff?
Let’s break it down.
What Is a Vapor Barrier and Why Do You Need One?
A vapor barrier is a thick sheet of plastic or reinforced polyethylene that’s laid on the ground beneath your mobile home. It acts as a moisture shield, preventing damp air and groundwater from rising into the crawl space, where it can lead to:
Mold and mildew growth
Wood rot in floor joists and beams
Insulation damage
Pest infestations
Higher energy bills due to moisture-heavy air
Flagstaff’s cooler temperatures, higher elevation, and snow during the winter months make it even more important to protect your home’s underside from moisture-related problems.
Average Cost to Install a Vapor Barrier in Flagstaff
The cost of vapor barrier installation depends on a few factors, including the size of your mobile home, the type and thickness of material, the condition of your crawl space, and whether you choose DIY or professional installation.
1. DIY Installation Costs
If you choose to install the vapor barrier yourself, you’ll need to purchase materials such as:
6 to 20 mil polyethylene sheeting
Seam tape
Ground stakes or anchors
💰 Typical DIY cost range:
$300 – $800 for materials (not including tools or labor).
Keep in mind that DIY vapor barrier installation is time-consuming, and working in crawl spaces can be challenging and unsafe if not done properly.
2. Professional Installation Costs in Flagstaff
Hiring a professional ensures that the vapor barrier is:
Properly sized and sealed
Laid flat with no gaps or tears
Anchored securely
Installed with attention to any existing moisture or pest issues
💰 Typical professional cost range:
Standard installation: $1,500 – $2,500
High-end or reinforced barrier with full crawl space prep: $2,500 – $3,500+
Additional services like removing old insulation, debris cleanup, pest-proofing, or installing ventilation systems will increase the cost, but also enhance the lifespan and effectiveness of the barrier.
Factors That Affect the Final Cost

Single-wide = Lower cost
Double-wide = Higher material and labor cost

Additional Upgrades
