Fix your crawl space for Good

Like most homeowners, chances are you overlook your crawl space until there’s an issue.  Your crawl space, the space between the main floor level of your home and the ground, is a hollow area anywhere from typically 1 to 3 feet high.  You don’t spend any time there – so why would you worry about it?

Crawlspace moisture can quickly become a costly problem when ignored.  A little rainwater isn’t bad, but if you do not dry the crawlspace, a heavy storm or melting snowfall can result in pools of water beneath your home.  The ground naturally absorbs some standing water, but the rest?  It ends up evaporating up into your home. As much as 40% of the air you breathe while in your home is coming from your crawl space, so conditioning this area becomes important for everyone in your home: you, your family members, and your friends.

The older the home with an unconditioned crawl space, the higher likelihood of damage.   A damp or wet crawl space can also cause hazardous mold and mildew to grow, structural wood damage, ductwork damage restricting your home’s airflow, and even sewer line or septic tank ruptures, depending on the severity.

Crawlspace Encapsulation Really Works

The greatest defense you have is to prevent moisture damage before it happens.

Advantage of Encapsulation

An encapsulation solution includes a sump pump and drainage system and should eliminate crawl space flooding. A high-quality encapsulation solution is one of the most cost-effective ways to prevent health hazards and structural damage.  An encapsulation solution is installed across a dirt floor to fight the moisture evaporating into your home.

Crawlspace encapsulation installation prevents water evaporation from rainfall and melting snow, hazardous mold and mildew growth, foundation damage, and sagging floors.  We’ll assess the needs of your specific crawlspace and determine different options based upon your unique situation.

Before crawl space encapsulation, it’s important to assess the existing damage and complete any needed repairs.  Our mold treatment and prevention coating kills most mold, mildew, and other biological growth that could be poisoning your home’s airflow.  Always use a qualified and experienced contractor when working on your home.

An untreated flooded crawl space can lead to mold and mildew growth and even severe structural damage, allergies and other breathing related problems.  Installing an encapsulation solution now can prevent costly repairs later.  Get a free estimate on our website or give us a call if you’d like to talk about crawlspace solutions for encapsulation, vapor barrier, sump pumps, and crawl space drainage.

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.
