Crawl space encapsulation Cherry Hill NJ

Cherry Hill & South Jersey

Crawl Space Encapsulation

Stop moisture, mold, and energy loss under your Cherry Hill home with a fully sealed crawl space system.

Your crawl space affects your whole home.

An unsealed crawl space is one of the most overlooked sources of moisture, mold, and high energy bills in South Jersey homes. Humid air rises from the soil, collects under floor joists, and works its way into your living space — affecting air quality, wood structure, and heating and cooling efficiency year-round. Crawl space encapsulation seals the problem at the source.

Basement Waterproofing Cherry Hill installs complete encapsulation systems using heavy-duty vapor barriers, conditioned air or dehumidification, and sealed vents designed for New Jersey's humid climate. We assess what your specific crawl space needs and install a system that lasts.

Vapor barrier installation in South Jersey crawl space

What crawl space encapsulation includes

Heavy-duty vapor barrier

We install a 20-mil reinforced polyethylene liner across the entire crawl space floor and up the walls, sealed at seams and penetrations. This blocks ground moisture from ever reaching the air inside the space.

Vent sealing

Traditional crawl space vents were designed to "air out" the space — but they actually pull humid outside air in during summer. We seal foundation vents as part of a conditioned crawl space system.

Dehumidification

A crawl space-rated dehumidifier maintains safe humidity levels year-round. Models we install drain automatically and are sized for the specific cubic footage of your crawl space.

Drainage integration

If standing water is present in the crawl space, we address drainage before encapsulation — whether that requires a sump pit, drain channel, or grading correction at the perimeter.

Signs your Cherry Hill crawl space needs encapsulation

Musty smell in living areas

If you smell dampness or mold anywhere in your home but can't find the source, the crawl space is the first place to check. Moisture air travels up through floors constantly.

High humidity or allergy symptoms

An unencapsulated crawl space contributes significantly to indoor relative humidity. If your home feels damp or family members have worsening allergy or asthma symptoms, moisture below may be the cause.

Soft or bouncy floors

Wood subfloor and joist rot from prolonged moisture exposure causes floors to flex or feel soft underfoot. Encapsulation stops the moisture source; rotted wood may also need replacement.

High heating and cooling bills

An unsealed crawl space is essentially a hole in your building envelope. Conditioned air escapes down and outside air comes up, forcing your HVAC system to work harder year-round.
