Crawl space encapsulation, repair, and insulation across NJ, NY & PA
Up to 40% of the air your family breathes rises up through the crawl space. If there's moisture, mold, pest contamination, or failing insulation down there, it's affecting every room above it. We handle crawl space encapsulation, crawl space insulation, moisture barriers, pest exclusion, and crawl space repair - the full scope, one crew, no handoffs.
Proof
Here's what actually happens under most NJ homes: wildlife gets in, nests in the insulation, insulation loses R-value, energy bills spike, moisture builds, mold grows, and air quality degrades upstairs. Most contractors fix one piece. We do the entire loop - pest exclusion, contamination cleanup, crawl space encapsulation, insulation, and moisture barriers.
We install heavy-duty vapor barriers, seal foundation vents, and control moisture at the source. A properly encapsulated crawl space reduces heating and cooling waste, improves comfort throughout the home, and protects the structure from long-term moisture damage.
We replace damaged or contaminated crawl space insulation with material that actually holds its R-value. Cellulose insulation is made from 80-85% recycled newspaper and delivers better thermal and sound performance than fiberglass - with 117% ROI according to national cost-vs-value data.
Most encapsulation contractors skip pest exclusion entirely. We seal the entry points that let rodents and wildlife into the crawl space before we encapsulate - so you're not sealing contamination inside a brand-new vapor barrier.
How it works
We assess moisture levels, insulation condition, pest evidence, structural concerns, and air quality impact before recommending the right combination of crawl space encapsulation, insulation, or repair work.
We clear pest debris, contaminated insulation, and moisture-damaged material so the encapsulation work goes over a clean base - not over a problem you can't see anymore.
We install the crawl space moisture barrier, replace insulation where needed, seal pest entry points, and set the space up so it supports the home above it instead of undermining it.
Scope & Coverage
A dehumidifier alone won't fix a crawl space with open vents, pest damage, and failing insulation. We inspect the full condition, identify every contributing factor, and build the crawl space repair scope around what's actually happening - not a one-size-fits-all package.
What customers say
“They showed me photos of everything they found, sealed every entry point, and the house has been silent since.”
Sarah M.
Montclair, NJ
“They were the only company that actually got into the attic with me and showed me the problem instead of just pitching a price.”
Dave K.
Staten Island, NY
“They cleared the infestation, cleaned the contamination, and got the attic inspection-ready fast. It saved the sale.”

Service areas
Crawl space encapsulation cost depends on square footage, accessibility, existing moisture severity, and whether pest contamination needs to be addressed first. The scope can range from a basic vapor barrier and dehumidifier to a full encapsulation with insulation, drainage, and sump pump work. We inspect first and provide a written proposal with exact pricing based on what we actually find.
Crawl space encapsulation seals the crawl space from the outside environment using a heavy-duty vapor barrier on the floor and walls, sealed foundation vents, insulation on crawl space walls, and a dehumidifier to maintain proper humidity. The goal is to turn a damp, vented crawl space into a dry, conditioned space that supports the home above it. Up to 40% of the air in your living space rises from below - encapsulation stops moisture, mold, and pest contamination from entering that air stream.
Yes. Up to 40% of the air in your living space rises from below. An un-encapsulated crawl space lets moisture, cold air, and contaminants into that air stream. Encapsulation with proper insulation typically reduces heating and cooling costs and improves comfort in every room above the crawl space.
Yes. Research shows homes with encapsulated crawl spaces can sell for a premium over comparable homes without encapsulation. Beyond the resale value, encapsulation prevents costly structural repairs from mold, floor joist damage, and foundation deterioration caused by unchecked moisture. We inspect first and scope the encapsulation to the actual conditions under your home.
Moisture attracts pests, and pests make moisture problems worse. Rodents and wildlife enter through crawl space vents and foundation gaps, nest in insulation (destroying its R-value), leave contamination that breeds mold, and create new entry points for more animals. Meanwhile, the damaged insulation lets more moisture in, energy bills climb, and air quality degrades upstairs. This is the full cycle we break - pest exclusion, contamination cleanup, insulation replacement, moisture barriers, and encapsulation. Most contractors only handle one piece.
