Crawlspace encapsulation in Myrtle Beach.
Encapsulation seals off your crawlspace with a heavy-duty vapor barrier, controlling humidity, reducing odors, preventing wood rot, increasing energy efficiency, and making the entire home more comfortable. In coastal South Carolina, where humidity rarely backs off, encapsulation is one of the highest-impact upgrades you can make.
Benefits of crawlspace encapsulation:
- Keeps humidity levels under control year-round
- Reduces musty odors and indoor allergens
- Prevents wood rot and structural damage
- Increases HVAC efficiency and lowers energy bills
- Makes the home more comfortable in every season
Temperature-controlled vents.
CPM installs temperature-controlled crawlspace vents that automatically open and close based on weather conditions. They open when conditions are dry and beneficial, and close when humid air would otherwise be drawn into the space. The result: less moisture, less mold pressure, and fewer pest-friendly conditions under your home.
Boracare wood treatments.
Boracare is an EPA-registered wood preservative applied directly to exposed wood in the crawlspace. It provides long-term protection against:
- Subterranean and Formosan termites
- Carpenter ants
- Wood-decaying fungi
- Old house borers and other wood-boring beetles
Combined with encapsulation, Boracare treatments form a long-term defensive layer for the entire substructure.

Crawlspace FAQs.
What's the difference between a vapor barrier and full encapsulation?
A vapor barrier is heavy plastic sheeting over the soil that blocks ground moisture, the essential first step. Full encapsulation seals the entire crawlspace: sealed liner up the walls, sealed vents, and usually a dehumidifier, turning the space into clean, dry, conditioned storage. Which one your home needs depends on how much moisture it's fighting; we'll measure and tell you honestly.
Can a damp crawlspace really cause pest problems?
It's the engine behind most of them. Subterranean termites need moisture and follow it to your framing; roaches and camel crickets breed in damp darkness; rodents nest in fallen insulation. Fix the moisture and every one of those pests loses its foothold, which is why a pest control company doing crawlspace work makes more sense than it might sound.
Do I need a dehumidifier if I encapsulate?
Usually, yes. Sealing the crawlspace stops outside moisture from getting in, but coastal South Carolina humidity still needs to be actively removed. A properly sized crawlspace dehumidifier holds the space below the ~60% humidity line where mold and wood rot start.
Why is crawlspace moisture such a problem near Myrtle Beach?
The Grand Strand sits on a shallow water table with high year-round humidity. Vented crawlspaces here actually pull in humid outdoor air all summer, which condenses on cool framing and ductwork. That's why so many local homes have musty smells, cupped floors, or fungus findings on their CL-100: the vents that were supposed to dry the space are feeding it.
Will encapsulation help my energy bills?
Typically, yes. A sealed, dry crawlspace means your HVAC isn't conditioning humid air leaking up through the floor, and ductwork running through the space stays efficient. Most homeowners notice more even floor temperatures and a modest drop in cooling costs, plus a house that just smells cleaner.
