Crawl Space Encapsulation in Western PA
Your crawl space may be out of sight, but the moisture it harbors affects your entire home. Up to 50% of the air you breathe on your first floor comes from below. Crawl space encapsulation seals this area with a heavy-duty 20-mil reinforced vapor barrier across the floor and walls, eliminates moisture with commercial-grade dehumidification, and transforms a problem space into a protected asset. The vapor barrier is the foundation of every encapsulation system -it blocks ground moisture from evaporating into your crawl space and home above.
What We Provide
Signs You Need Crawl Space
If you notice any of these warning signs, contact us for a free inspection.
Musty Smells on Your First Floor
If your first floor has a persistent musty or damp smell, your crawl space is likely the source. The stack effect pulls crawl space air up through your living areas.
High Humidity in Your Home
Excessive humidity that your HVAC system struggles to control often originates from an open, vented crawl space pulling in moist air from outside.
Sagging or Bouncy Floors
Moisture in your crawl space can cause floor joists and beams to weaken over time, resulting in floors that feel soft, bouncy, or visibly saggy.
Condensation on Pipes or Ductwork
Water droplets forming on crawl space pipes, ductwork, or floor joists signal high humidity levels. Without a vapor barrier, ground moisture continuously evaporates into the space and condenses on cooler surfaces, accelerating corrosion and wood decay.
Pest or Insect Problems
Open crawl spaces are an invitation for pests. Termites, carpenter ants, rodents, and other pests thrive in dark, damp environments.
How Our Crawl Space Process Works
Crawl Space Inspection
We thoroughly inspect your crawl space -checking moisture levels, structural integrity, existing insulation, drainage conditions, and signs of mold or pest damage.
Preparation & Remediation
We address any existing mold, remove debris, repair structural issues, and prepare the space for encapsulation.
Encapsulation Installation
We install a heavy-duty vapor barrier across the entire crawl space floor and walls, seal all vents, and install a dehumidifier and any necessary drainage.
Final Inspection & Monitoring
We verify moisture levels, test all systems, and provide documentation. Many of our dehumidifier systems include monitoring capabilities.
Crawl Space Questions Answered
Common questions about our services. Can't find your answer? Call us.
How much does crawl space encapsulation cost?
Crawl space encapsulation in Western PA typically ranges from $5,000 to $15,000 depending on the size of the crawl space, condition of the existing space, and whether additional work like drainage or structural repair is needed. We provide free estimates with detailed pricing.
Is crawl space encapsulation worth it?
Absolutely. Encapsulation reduces energy costs (often 15-20% savings on heating/cooling), eliminates mold and moisture problems, improves indoor air quality, prevents pest intrusion, and protects your home's structural integrity. It also increases home value.
Should crawl space vents be open or closed?
Modern building science has conclusively shown that crawl space vents should be sealed. Open vents allow humid outside air into the crawl space, where it condenses on cooler surfaces and creates moisture problems. Encapsulation with sealed vents and dehumidification is the current best practice.
How long does crawl space encapsulation last?
A properly installed crawl space encapsulation system lasts 15-25 years or more. The vapor barrier itself is extremely durable. The dehumidifier may need replacement after 8-12 years. We provide warranty coverage on our installations.
What is a crawl space vapor barrier and why does thickness matter?
A crawl space vapor barrier is a heavy-duty polyethylene liner installed across the crawl space floor and up the walls to block ground moisture from entering the space. We use a 20-mil reinforced vapor barrier -significantly thicker than the 6-mil sheeting used in basic installations. Thicker barriers resist tears and punctures, last longer, and provide a genuine moisture seal rather than just a moisture reducer. A proper vapor barrier is the single most important component of any crawl space encapsulation system.
