Closed-Cell Spray Foam
Closed-cell spray foam insulates the crawl space walls and rim joists while sealing air leaks. It resists water, so it holds in damp crawl spaces.

The Service
Crawl Space Insulation in New Jersey
The crawl space has a bigger effect on your home than most people realize. Air from the crawl space rises into the living area, carrying cold, damp, or musty conditions with it. Fixing the crawl space fixes problems you feel one floor up.
Sky Blue Insulation seals, insulates, and encapsulates crawl spaces in New Jersey homes and businesses. We use closed-cell spray foam, rigid insulation, and vapor barriers to lock out cold air and moisture.
Moisture is the real enemy in a crawl space. Standing water, damp soil, and humid air lead to mold, wood rot, and pests over time. We seal those sources and add a vapor barrier so the space stays dry.

The Two Approaches
Crawl Space Spray Foam and Encapsulation
A crawl space needs the right mix of insulation and moisture control. We offer closed-cell spray foam and full encapsulation, matched to your crawl space.
Full Encapsulation
Encapsulation wraps the crawl space in a heavy vapor barrier over the floor and walls. With perimeter insulation, it locks out ground moisture and humidity.

Free, Honest Estimates
Every estimate is free and clear, with the crawl space scope and price in writing before we begin work.
Should I insulate my crawl space?
If your floors are cold, your bills are high, or the space feels damp, yes. A sealed, insulated crawl space fixes all three and protects the structure above.
What is crawl space encapsulation?
It's when we seal the whole crawl space with a heavy vapor barrier over the floor and walls, then insulate the perimeter. It turns a damp dirt space into a clean, dry one.
Do I need a vapor barrier?
In most New Jersey crawl spaces, yes. A vapor barrier blocks moisture rising from the soil, which is the main cause of mold, rot, and musty air.
Will this lower my energy bills?
It should. Sealing and insulating the crawl space stops heat loss under your floors, so most homes use less energy. We don't offer a written savings warranty, but the work pays off.
My crawl space is wet. Can you still help?
Yes, but we stop the water first. Once the moisture sources are handled and the space is dry, we seal, insulate, and encapsulate so it stays that way.
Do you serve my New Jersey town?
We cover a wide part of New Jersey, including Jersey City, Short Hills, Livingston, Ridgewood, Alpine, Princeton, and Atlantic City. If you're nearby, just call and ask.
