Crawl Space Encapsulation
in Greenville
Encapsulation keeps moisture out and comfort in!
Is Your Air Dirty?
Conventional ventilated crawl spaces allow moisture and "dirty" air to enter our homes.
In Greenville's humid climate, moisture is a major threat to homes, especially in the crawl space. Crawl space encapsulation is one of the most effective ways to protect your home from excess moisture, mold, and pests. At Palmetto Exterminators, we specialize in sealing and safeguarding crawl spaces to improve your home's health, its longevity, and energy efficiency.
A sealed crawl space is 15-18% more energy efficient than a ventilated crawl space!
Why Encapsulation is Important
Without crawl space encapsulation, moisture can quietly wreak havoc on a Greenville home over time. The region's naturally humid climate, combined with frequent rainfall, creates ideal conditions for dampness to settle beneath homes. This excess moisture can lead to wood rot, warped or sagging floors, and even compromised structural supports. Over time, the persistent damp environment encourages mold and mildew growth, which can spread into living spaces and negatively impact indoor air quality, especially for those with allergies or respiratory conditions.
Moisture also attracts unwanted pests like termites, carpenter ants, rodents, and cockroaches, all of which can cause additional damage and create serious health concerns. Left unchecked, these issues can lead to costly repairs and long-term damage that could have been prevented with professional crawl space encapsulation.
How We Control Moisture
Crawlspace moisture can not only be destructive to property but has been proven to negatively impact our health. Sealing your crawlspace provides better air quality and relief to your HVAC system. A properly sealed crawlspace is 15-18% more energy efficient than a ventilated crawl space. Dry crawl spaces are less attractive to pests.
Vapor Barrier & Wrapping Foundation Piers
We'll set up a woven vapor barrier, ensuring it overlaps and seal all seams with tape. Then we'll wrap foundation piers with wall liner and seal the top with spray foam.
Exterior Wall Insulation
We will insulate the exterior foundation wall with Nisus Bora-Foam (R10) or a wall blanket (12) and sealed at the top with spray foam. The exterior band will be insulated with Batt insulation (R19).
Installation of Dehumidifier
A dehumidifier, sized appropriately, will be placed in the crawlspace. The condensation will be drained away from the home and the homeowner will be provided a remote monitor to track temperature and relative humidity.
Annual Inspection
We offer an annual inspection that includes filter replacements, minor repairs, and moisture readings of the crawl space wood to ensure optimal air quality for your family and home.
We've Got You Covered From The Ground Up
What is crawl space encapsulation?
Crawl space encapsulation is the process of sealing off your crawl space to protect it from moisture, humidity, and pests. It involves installing a vapor barrier on the ground and walls, sealing vents and cracks, and often adding a dehumidifier to maintain dry, stable conditions.
How do I know if I need crawl space encapsulation?
If you notice musty odors, mold, high humidity, cold floors, or increased pest activity, your crawl space may be contributing to the problem. Palmetto Exterminators can schedule an inspection to help determine if encapsulation is the right solution.
How long does crawl space encapsulation take?
Most encapsulation projects take 1-3 days, depending on the size and condition of your crawl space and any prep work needed, such as insulation removal or drainage improvements.
Will encapsulating my crawl space reduce energy bills?
Yes, sealing your crawl space helps improve energy efficiency by reducing humidity and preventing outside air from seeping in. Many Greenville homeowners notice lower heating and cooling costs after encapsulation.
Is a vapor barrier the same as encapsulation?
-
Not quite. A vapor barrier is part of encapsulation—it covers the crawl space floor to block ground moisture. Full crawl space encapsulation includes wall coverage, sealing vents, and adding a dehumidifier for complete moisture control.
