Moisture Control • Mold Prevention • Energy Savings • Structural Protection
Crawl space encapsulation transforms damp, mold-prone crawl spaces into clean, dry, controlled environments that protect your home's structural integrity and indoor air quality. Atlanta's humid subtropical climate creates perfect conditions for moisture accumulation, mold growth, wood rot, and pest infestations in unprotected crawl spaces. Our professional encapsulation process installs heavy-duty vapor barriers, seals vents and gaps, controls humidity with dehumidifiers, and creates a conditioned space that significantly reduces energy costs while preventing mold, eliminating musty odors, and protecting floor joists and subflooring from moisture damage. Properly encapsulated crawl spaces improve HVAC efficiency, enhance indoor air quality throughout your home, increase property value, and provide long-term protection against moisture-related problems that plague traditional vented crawl spaces in Georgia's challenging climate.
Unencapsulated crawl spaces in Atlanta create numerous problems affecting health, comfort, energy costs, and structural integrity.
Ground moisture vapor rises through exposed soil creating humidity levels above 70%. Condensation forms on cold surfaces, pipes, and HVAC ductwork. Chronic dampness promotes mold growth and wood rot.
Damp crawl spaces provide perfect environment for mold colonization. Spores spread throughout home via stack effect. Black mold, Aspergillus, and Penicillium thrive in wet conditions.
Moisture deteriorates floor joists, sill plates, subflooring, and support posts. Wood-destroying fungi and termites attack wet lumber. Structural integrity compromised causing sagging floors.
Damp dark crawl spaces attract rodents, insects, spiders, and termites. Pests enter living spaces through gaps and cracks. Droppings and nesting materials contaminate insulation.
Up to 50% of indoor air originates from crawl space via stack effect. Musty odors, mold spores, allergens, and contaminants circulate throughout home. Residents experience respiratory issues.
Vented crawl spaces allow unconditioned humid air infiltration. HVAC systems work harder cooling and dehumidifying. Air leaks through floor account for significant heat loss and gain.
Professional crawl space encapsulation following building science best practices for moisture control and energy efficiency.
Comprehensive crawl space evaluation identifies moisture sources, existing damage, structural issues, and mold growth. We measure relative humidity, check for standing water, inspect foundation walls for cracks, examine floor joists and subflooring for rot, evaluate drainage around foundation, and assess ventilation system. Thermal imaging detects hidden moisture in walls and insulation. Detailed assessment determines encapsulation scope, necessary repairs, and optimal moisture control strategy specific to your property conditions and budget requirements.
Complete crawl space cleaning removes debris, contaminated insulation, mold-damaged materials, and pest waste. We remove old fiberglass insulation hanging from floor joists, clear construction debris and stored items, eliminate rodent nesting materials and droppings, remove damaged vapor barriers and plastic sheeting, and clear vegetation growth from soil. Professional cleaning creates clean slate for encapsulation installation. HEPA vacuuming removes dust and mold spores from surfaces. This critical preparation ensures vapor barrier adheres properly and encapsulation system functions optimally.
Proper drainage prevents water intrusion and standing water accumulation. We install perimeter drainage systems channeling water away from foundation, add sump pumps in low areas where water collects, regrade soil creating positive drainage away from house, extend downspouts directing roof water away from crawl space, and repair foundation cracks allowing groundwater seepage. French drains, interior drainage channels, and exterior waterproofing address severe water problems. Effective water management eliminates moisture source before encapsulation preventing future flooding and humidity issues.
Moisture-damaged structural components require repair before encapsulation. Our licensed contractors replace rotted floor joists, sill plates, and subflooring compromised by wood rot. We sister damaged joists with new lumber providing additional support, install supplemental support posts and beams correcting sagging floors, replace deteriorated rim joists and band boards, and treat wood for termites and wood-destroying fungi. Structural repairs restore load-bearing capacity ensuring safe, stable flooring. Proper repairs prevent future problems and maximize encapsulation effectiveness protecting your investment.
Heavy-duty polyethylene vapor barrier forms foundation of crawl space encapsulation. We install reinforced 10-20 mil thick white barrier covering entire crawl space floor, running material up foundation walls 12-18 inches, overlapping seams minimum 12 inches sealing with waterproof tape, mechanically fastening barrier to foundation walls using termination bars, sealing around piers, posts, and penetrations preventing moisture bypass, and creating continuous moisture barrier blocking 99% ground vapor transmission. White surface brightens crawl space improving visibility for inspections. Durable reinforced material resists tears and punctures providing decades of protection.
Complete air sealing and insulation maximizes energy efficiency and moisture control. We seal crawl space vents permanently with foam board and spray foam preventing outside humid air entry, seal rim joists with closed-cell spray foam stopping air leakage into living spaces, insulate foundation walls with rigid foam board maintaining conditioned environment, seal penetrations including plumbing pipes, electrical wiring, and HVAC ductwork, and caulk gaps and cracks in sill plates and foundation preventing pest entry. Proper sealing creates conditioned crawl space within building envelope dramatically improving energy efficiency and indoor air quality.
Commercial-grade dehumidifier maintains optimal humidity levels year-round. We install properly-sized dehumidifier based on crawl space volume, position unit for optimal air circulation and drainage, connect condensate drain line to sump pump or exterior drainage, set humidity controls maintaining relative humidity below 55%, and install hygrometer monitoring humidity levels continuously. Dehumidifier removes moisture from air preventing condensation, mold growth, and musty odors. Automatic operation requires minimal maintenance while providing constant humidity control. Energy-efficient units operate economically protecting your investment through superior moisture management.
Thorough final inspection verifies complete installation and optimal system performance. We verify vapor barrier continuity with no gaps or tears, confirm proper sealing of all vents and penetrations, test dehumidifier operation and drainage, measure humidity levels confirming target range, inspect structural repairs and support systems, photograph completed work for documentation, and provide maintenance instructions and warranty information. Comprehensive warranty covers materials and workmanship. We schedule follow-up inspection ensuring system performs optimally. Professional installation provides long-term moisture protection, energy savings, and structural preservation.
Encapsulation investment varies based on crawl space size, access difficulty, existing damage, drainage needs, and system components. Professional installation provides long-term value through energy savings, structural protection, and mold prevention.
Professional crawl space encapsulation service encompasses:
Encapsulation investment pays for itself through lower energy bills, prevented structural damage, and improved home value.
Delaying crawl space encapsulation leads to escalating problems and exponentially increasing costs. Chronic moisture causes extensive wood rot requiring tens of thousands in structural repairs including floor joist replacement, subflooring reconstruction, and foundation work. Mold contamination necessitates expensive remediation procedures. High energy bills waste thousands annually from HVAC inefficiency. Property value decreases significantly when inspections reveal moisture damage and mold. Insurance claims for water damage and mold may be denied if maintenance neglect is evident. Professional encapsulation prevents these costly problems providing immediate and long-term financial benefits.
Preventing moisture damage protects your largest investment. Floor joist replacement costs exceed crawl space encapsulation investment by 300-500%. Termite damage treatment and wood replacement runs thousands of dollars. Foundation repairs from moisture deterioration cost tens of thousands.
