15–30% reduction in energy bills
Eliminates mold, musty odors, and pest-friendly conditions
A proven, methodical approach refined over 20+ years of professional installation.
We thoroughly inspect your crawl space — moisture levels, existing insulation, structural condition, drainage, and ventilation — to design the right encapsulation system.
Old insulation, debris, and standing water are removed. The crawl space is cleaned and any drainage issues are addressed before encapsulation begins.
Vents are sealed, a heavy-duty vapor barrier is installed on the floor and walls, seams are sealed, and wall insulation is applied. Optional dehumidifier is installed.
We verify complete coverage, sealed seams, proper insulation thickness, and — if installed — dehumidifier function, ensuring your crawl space is fully protected.
A vented, unencapsulated crawl space is one of the most problematic areas in Denver homes. Ground moisture rises continuously, cold air infiltrates through vents during winter, and the humid, dark environment provides ideal conditions for mold growth, pest infestations, and wood rot. These problems don't stay in the crawl space — they migrate upward into your living areas, affecting indoor air quality, comfort, and energy costs. Crawl space encapsulation solves these problems comprehensively. The process involves sealing crawl space vents, installing a heavy-duty (20+ mil) polyethylene vapor barrier over the floor and up the foundation walls, insulating the walls with closed-cell spray foam or rigid foam board, and optionally adding a dehumidifier for active moisture control. The result is a clean, dry, conditioned space that functions as part of your home's thermal envelope rather than working against it. Sky Insulation provides complete crawl space encapsulation for Denver homeowners. Our process addresses every aspect of crawl space moisture and energy management — from vapor barrier installation and insulation to vent sealing and dehumidification — delivering 15–30% reductions in energy bills and dramatically healthier indoor air quality.
Encapsulation stops ground moisture from entering your crawl space, eliminating the conditions that cause mold, mildew, and wood rot.
A sealed, insulated crawl space reduces energy loss by 15–30%, with warmer floors in winter and reduced HVAC workload year-round.
Up to 50% of the air in your home rises from below. An encapsulated crawl space means cleaner, drier air throughout your living spaces.
Heavy-duty vapor barriers and sealed insulation provide decades of moisture and energy protection — a permanent improvement to your home.
Crawl space encapsulation is the process of sealing your crawl space from the ground and outside air using a heavy-duty vapor barrier, sealed vents, and insulation. This creates a dry, conditioned space that prevents moisture problems and improves energy efficiency.
A vapor barrier alone covers just the crawl space floor. Full encapsulation includes a vapor barrier on floors AND walls, sealed vents, insulation, and sometimes a dehumidifier — providing comprehensive moisture and energy management.
Yes. Encapsulation eliminates the moisture and humidity that mold needs to grow. By sealing out ground moisture and controlling humidity levels, an encapsulated crawl space creates an environment where mold cannot thrive.
In most Denver crawl spaces, the combination of a vapor barrier and sealed insulation provides sufficient moisture control. In cases with persistent high humidity or previous flooding, we may recommend a dehumidifier for active moisture management.
Quality encapsulation materials (20+ mil vapor barriers and closed-cell insulation) are designed to last 20+ years with minimal maintenance. The dehumidifier, if installed, may need periodic servicing.
