Why Mobile Home Encapsulation is Critical

Mobile homes face unique moisture challenges that require specialized solutions

🏠 Structural Protection

Mobile homes are more susceptible to moisture damage due to their construction. Encapsulation prevents wood rot, floor sagging, and structural deterioration that can cost $15,000+ to repair.

💨 Air Quality Improvement

Crawl space moisture creates mold and mildew that directly affects indoor air quality. Encapsulation creates a healthy environment by eliminating moisture sources and improving ventilation.

⚡ Energy Efficiency

Unencapsulated crawl spaces can account for 30-50% of energy loss in mobile homes. Proper encapsulation reduces heating and cooling costs by creating an effective thermal barrier.

🐭 Pest Control

Moisture attracts rodents and insects that can damage wiring and plumbing. Encapsulation eliminates the damp environment pests need while creating physical barriers to entry.

💰 Home Value

Professional encapsulation can increase mobile home value by $5,000-15,000. It's an attractive feature for buyers and demonstrates proper maintenance and care.

🔧 System Protection

HVAC systems, plumbing, and electrical work better in controlled environments. Encapsulation protects these expensive systems from moisture damage and extends their lifespan.

Professional Installation Process

30+ years of mobile home experience - follow our proven encapsulation method

1

Crawl Space Preparation

Critical First Step: Remove all debris, repair any structural issues, and address existing moisture problems.

Tools Needed: Shovel, flashlight, moisture meter, safety equipment.

Pro Tip: Document with photos before starting for insurance purposes. Check for water leaks first. The EPA provides mold guidelines for safe remediation.

2

Moisture & Mold Remediation

Safety Priority: Test for mold, treat affected areas, and ensure space is completely dry before encapsulation.

Materials: Mold test kits, antimicrobial treatment, dehumidifier for pre-drying. According to the CDC, proper ventilation during remediation is critical.

Timeline: Allow 3-7 days for complete drying depending on conditions.

3

Air Sealing & Insulation

Foundation Work: Seal all air leaks with spray foam, insulate walls, and create thermal barrier.

Technique: Work from top to bottom, seal rim joists, and insulate foundation walls completely.

Energy Efficiency: The Department of Energy recommends crawl space encapsulation as a top weatherization strategy for mobile homes.

4

Vapor Barrier Installation

Critical Process: Install heavy-duty plastic sheeting with proper overlap and sealing techniques.

Professional Method: 6-inch overlap minimum, sealed with butyl tape, attached to walls 6 inches above grade.

Quality Check: No gaps, tears, or unsealed seams - inspect thoroughly.

5

Moisture Control System

Essential Component: Install appropriately-sized dehumidifier with proper drainage and controls.

Sizing Guide: 70+ pints for small mobile homes, 130+ pints for larger homes or humid climates.

Maintenance: Set up automatic drainage and monitoring systems.

6

Final Inspection & Monitoring

Quality Assurance: Complete visual inspection, test moisture levels, and establish monitoring routine.

Documentation: Record humidity levels, take completion photos, create maintenance schedule.

Warranty Protection: Keep all material receipts and installation documentation.

⚠️ Don't Make These Costly Mistakes

Avoid these common errors that can lead to thousands in damage

🚫 Skipping Moisture Testing

Encapsulating over existing moisture problems traps water and creates worse issues

🚫 Using Thin Plastic

6-mil minimum thickness required - thinner materials tear and fail quickly

🚫 Poor Seam Sealing

Gaps in seams allow moisture entry - use professional-grade seaming tape

🚫 No Dehumidification

Encapsulation without moisture control creates condensation problems

Crawl Space Encapsulation FAQ

Is crawl space encapsulation worth it for mobile homes? +
Absolutely! Mobile homes benefit more from encapsulation than traditional homes due to their construction methods and elevation. The investment typically pays for itself within 3-5 years through energy savings, reduced repairs, and improved indoor air quality. For mobile homes, it's not just beneficial - it's essential for long-term structural integrity.
Can I encapsulate my mobile home crawl space myself? +
Yes! Mobile home crawl spaces are actually easier to encapsulate than traditional basements because they're more accessible and have simpler layouts. With proper materials and our step-by-step guide, most homeowners can complete the project over a weekend. The key is using professional-grade materials and following proper sealing techniques.
What thickness plastic should I use for mobile home encapsulation? +
For mobile homes, we recommend minimum 6-mil thickness, with 10-12 mil being optimal for durability. The plastic should be white or clear (not black) to allow for visual inspection, and must be treated for UV resistance. Thinner materials tear easily during installation and don't provide adequate long-term protection.
How much does DIY mobile home encapsulation cost? +
DIY encapsulation for a typical 1,200 sq ft mobile home costs $750-1,400 in materials, compared to $4,400-7,000 for professional installation. This includes heavy-duty plastic ($200-400), seaming tape ($50-100), dehumidifier ($300-500), spray foam ($150-300), and safety equipment ($100-200). You'll save $3,000-5,600 doing it yourself.
Do I need a dehumidifier in an encapsulated crawl space? +
Yes, a dehumidifier is essential for mobile home crawl spaces. Even with perfect encapsulation, some moisture will still be present from concrete curing, minor air leaks, and humidity from the house above. A properly sized dehumidifier (70-130 pints for mobile homes) maintains optimal humidity levels and prevents condensation problems.
How long does mobile home encapsulation last? +
Quality encapsulation using proper materials should last 15-20 years with minimal maintenance. The key factors are using heavy-duty plastic (10+ mil), professional seaming tape, and maintaining proper humidity control. Annual inspections and prompt repair of any damage will maximize lifespan and effectiveness.
Can encapsulation help with mobile home belly wrap problems? +
Yes! Encapsulation works hand-in-hand with belly wrap repairs. While belly wrap protects the underside from external moisture, encapsulation controls internal humidity and ground moisture. Together, they provide comprehensive moisture protection that's essential for mobile home longevity.
What's the difference between encapsulation and just using a vapor barrier? +
Encapsulation is a complete system that includes vapor barrier, air sealing, insulation, and moisture control. A vapor barrier alone only addresses ground moisture. Complete encapsulation also seals air leaks, insulates walls, and includes dehumidification - providing far superior moisture control, energy efficiency, and indoor air quality benefits.
