Crawl Space Services in NJ, NY & PA
Crawl space problems? We handle the whole thing. One crew.
Encapsulation, insulation, pest exclusion, and moisture control. Full cost in writing before work starts.

The short answer
Attic Fanatics does crawl space work in New Jersey, eastern Pennsylvania, Staten Island, and Rockland County, NY. Cleanout, rodent exclusion, insulation, vapor barrier, and full encapsulation, with moisture handled first. NJ encapsulation starting points: $3,600 to $18,000 and up. Free inspection, written estimate first; same-day generally available when the schedule allows.
Most companies do one thing down there. We do all of it.
Call a pest company and they will trap mice but ignore the moisture that attracted them. Call an encapsulation company and they will seal it up but leave rodent contamination behind the vapor barrier. Call us, and we handle the whole picture: contamination cleanup, pest exclusion, moisture control, insulation, and encapsulation.
One crew, one plan, one visit. No subcontractors. No coordinating three different companies. No guessing about who is responsible if something comes back.

Family-owned. 5M+ sq ft restored.
Signs your crawl space needs attention
Not sure? That is what the inspection is for. Free, no obligation.
How crawl space air enters your home
Your crawl space connects to your living space through gaps in the subfloor, plumbing penetrations, HVAC ductwork, and natural pressure differences in the structure. Whatever is down there (moisture, mold spores, rodent contamination, musty air) migrates upward into the rooms where your family lives. Fixing the crawl space fixes the house above it.
Before
AfterRepresentative before and after from our attic restoration work. Contaminated insulation out, clean install in.
How crawl space encapsulation works
One call, one crew, one plan. Here is the process from start to finish.
We crawl under the house and show you everything.
Free inspection with photos. We check moisture levels, entry points, insulation condition, and contamination. You get the full cost in writing before any work starts. No surprises.
Clean out the contamination.
Animal droppings, destroyed insulation, debris. It all comes out. We decontaminate the surfaces so you are starting clean, not sealing problems under a vapor barrier.
Seal every gap that lets pests in.
Every foundation crack, vent opening, and pipe penetration that gives rodents or wildlife access gets sealed with hardware cloth and metal flashing. Screwed in. Not foamed.
Encapsulate and insulate.
Vapor barrier down, vents sealed, insulation installed. When we leave, the crawl space is dry, sealed, and working for your home instead of against it.
Why we do pest exclusion and encapsulation together
Seal the crawl space without removing the pests, and you have trapped them inside a vapor barrier. Remove the pests without sealing, and new ones move in within weeks. We handle both in one plan because that is the only way it actually works.
We stand behind every crawl space we seal.
Every entry point is sealed with hardware cloth and metal flashing, screwed into solid wood. If pests get back in through a sealed area, we come back at no charge.
