Fix your crawl space for Good

Like many homeowners in Philadelphia, you probably don’t think about your crawl space unless a problem appears. Your crawl space is the area between your home’s main floor and the ground, usually just one to three feet high. Since it’s not easily accessible in many city homes near Fishtown or Roxborough, it’s often ignored.

Crawl space moisture can become a serious concern if left untreated. While small amounts of water may not seem problematic, heavy rainstorms and snowmelt can lead to moisture buildup beneath your home. Some water is absorbed into the soil, but the rest evaporates upward into your living space. Up to 40% of the air inside your home can come from the crawl space, making moisture control important for indoor comfort.

Older homes with unconditioned crawl spaces are especially vulnerable. Ongoing dampness can lead to biological growth, wood damage, ductwork issues that restrict airflow, and in severe cases, plumbing or sewer line concerns.

Crawlspace Encapsulation Really Works

The best way to protect your Philadelphia home is to stop moisture problems before they lead to long-term damage.

Advantage of Encapsulation

A crawl space encapsulation solution typically includes a drainage system and sump pump to help manage groundwater and reduce flooding. A professionally installed encapsulation system is one of the most cost-effective ways to protect against structural damage and indoor air quality concerns. The vapor barrier is installed across the dirt floor to prevent moisture from evaporating into your home.

Crawl space encapsulation in Philadelphia, PA helps reduce moisture from rainfall and snowmelt, limits biological growth, protects your foundation, and can help prevent sagging floors. We evaluate each crawl space individually and recommend solutions based on your home’s unique conditions.

Before encapsulation begins, existing damage should be repaired. Our treatment process addresses biological growth that can impact your home’s airflow. Always work with a qualified and experienced contractor when investing in crawl space repairs.

An untreated crawl space can lead to costly structural repairs and indoor air quality issues. Installing an encapsulation system now can help prevent future damage.

Crawl Space Encapsulation FAQs

What problems does encapsulation solve?

It reduces moisture that can drive biological growth, musty odors, wood rot, and cold floors—improving comfort and air quality in living areas.

What’s included in a proper encapsulation?

Seam-sealed vapor barrier, sealed vents, insulated rim/band as appropriate, drainage to a sump (if needed), and a dehumidifier for long-term humidity control.

Do I need a sump pump or dehumidifier?

Often yes. Many local crawl spaces see groundwater or seasonal humidity; pumps manage water, dehumidifiers control moisture in the air.

How long does installation take?

How do I know if I need foundation repair?
