Crawl Space Encapsulation in Shrewsbury, NJ

How We Solve Dampness, Cold Air and Crawl Space Problems for Local Homeowners

Homeowners in Shrewsbury recently contacted our team after noticing something many Monmouth County homeowners experience — cold floors, damp indoor air, and rising humidity inside the home.

The culprit?

👉 An unsealed crawl space allowing moisture and outside air to enter the living environment.

This project is a perfect example of how crawl space encapsulation can dramatically improve comfort, air quality, and energy efficiency.

🚨 The Problem: Damp Crawl Space & Cold Air Entering the Home

When we inspected the home, several issues were immediately clear:

Exposed soil releasing ground moisture
Cold outside air entering through vents and gaps
Elevated humidity beneath the home
Insulation performance reduced by moisture exposure

Many homeowners don’t realize this, but up to 40–50% of the air inside your home can originate from the crawl space.

That means moisture, odors, and cold air don’t stay below — they rise directly into living areas.

Common symptoms include:

❄️ Cold floors in winter
🌫️ Musty odors
💧 Indoor humidity problems
📈 Higher heating bills

🔎 Why Crawl Spaces Cause Problems in Shrewsbury Homes

Homes throughout Shrewsbury and coastal Monmouth County often face crawl space challenges due to:

Seasonal groundwater moisture
Coastal humidity levels
Older vented crawl space designs
Temperature swings between seasons

Traditional vented crawl spaces were once believed to “dry themselves out,” but modern building science shows the opposite often happens.

Instead, vents allow:

Humid summer air inside
Cold winter air beneath floors
Condensation buildup year-round

✅ Our Crawl Space Encapsulation Solution

To permanently address the issue, we performed a full crawl space encapsulation system installation.

Our process included:

✅ Installing a heavy-duty vapor barrier across floors and walls
✅ Sealing vents and air entry points
✅ Isolating the crawl space from outside moisture
✅ Creating a clean, controlled environment beneath the home

The transformation was immediate.

The crawl space went from damp and exposed → clean, sealed, and protected.

🌡️ Immediate Benefits After Encapsulation

After completion, the homeowner experienced:

✔️ Warmer floors throughout the home
✔️ Reduced indoor humidity
✔️ Improved heating efficiency
✔️ Elimination of musty crawl space odors
✔️ Long-term moisture protection

Encapsulation essentially converts the crawl space into a conditioned part of the home, rather than an outdoor environment underneath it.

🧠 Building Science: Why Encapsulation Works

Moisture moves through homes via three main pathways:

Air movement
Vapor diffusion
Temperature differences

An exposed crawl space continuously feeds moisture upward through what’s known as the stack effect — where warm air rising pulls crawl space air into living spaces.

Encapsulation interrupts this cycle by:

✅ Blocking ground vapor
✅ Preventing humid air intrusion
✅ Stabilizing temperature below the home

The result is better comfort and healthier indoor air.
