Why Montgomery Homes Need Crawl Space Encapsulation
Central Alabama averages over 50 inches of rainfall per year, and summer humidity regularly exceeds 90%. An unencapsulated crawl space acts like a sponge - absorbing ground moisture and outdoor humidity. This moisture condenses on floor joists and subfloor, accelerating wood rot and mold growth. Over time, moisture damage compromises structural integrity and creates persistent air quality issues throughout the home.
What Our Encapsulation System Includes
A complete Montgomery Foundation Repair Co encapsulation installation includes: a 20-mil reinforced vapor barrier sealed across the entire crawl space floor and up the walls, foam-sealed foundation vents (sealed in conditioned crawl spaces), drainage matting under the barrier for ground moisture management, sealing of all penetrations, and a properly sized dehumidifier to maintain indoor humidity below 55% year-round. We also inspect and address any existing moisture damage before sealing.
Encapsulation vs. Vapor Barrier - What's the Difference?
A standard vapor barrier is a thin plastic sheet that limits (but doesn't eliminate) ground moisture transmission. Encapsulation is a complete system - thick reinforced liner, vent sealing, and active humidity control - that converts the crawl space into a semi-conditioned space. Encapsulation is significantly more effective in Alabama's climate and qualifies for energy efficiency incentives in some cases.
Frequently Asked Questions
Do you offer free estimates in Montgomery, AL?
Yes. Montgomery Foundation Repair Co provides free on-site inspections and written estimates throughout Montgomery County - no obligation. Call (334) 835-5928 to schedule.
Why is crawl space encapsulation important in Montgomery?
Montgomery's humid subtropical climate creates ideal conditions for mold, wood rot, and pest infestation in unprotected crawl spaces. Standing water from clay soil drainage worsens structural damage. Encapsulation seals out moisture, improves indoor air quality, and protects floor joists.
How long does crawl space encapsulation last?
A properly installed encapsulation system with a quality vapor barrier lasts 20–25 years. The dehumidifier requires annual maintenance. Montgomery Foundation Repair Co uses 20-mil reinforced barriers and provides a written warranty on all encapsulation work.
Will crawl space encapsulation lower my energy bills?
Yes. Sealing air gaps in the crawl space reduces HVAC load significantly. Montgomery homeowners typically see 15–25% reductions in heating and cooling costs after full encapsulation, often paying back the investment within 5–7 years.
