Babylon homeowners have no shortage of insulation companies to call — what's scarce is one that gives a fixed written price, explains what the job actually needs, and answers the phone after the deposit clears. That's the standard Coastal Insulation Co works to across Long Island, Babylon included.
Many Long Island homes — especially mid-century builds in Levittown, Hicksville, and Massapequa — were built with minimal insulation. Upgrading your attic, walls, and crawl space dramatically cuts PSEG Long Island bills and improves year-round comfort. Our BPI-certified crews serve all of Nassau and Suffolk counties with spray foam, blown-in, and batt insulation.
Blown-in and batt insulation for attics — the #1 source of heat loss in most homes. Immediate energy savings.
Dense-pack cellulose and injection foam for existing walls. No major demolition required.
Closed-cell and open-cell spray foam for maximum R-value, air sealing, and moisture protection.
Rigid board, spray foam, and vapor barriers for below-grade spaces. Stop moisture and heat loss at the foundation.
Yes — Babylon is inside our core Long Island service area, not the edge of it. Our crews are in and around Babylon regularly, which matters for scheduling and for honoring warranty visits.
Most Babylon estimates are scheduled within a few days, and urgent calls are prioritized the same day whenever crews are in the area. Call (631) 496-4322 for the current schedule.
It depends on the scope, which is why we price from an on-site assessment — not over the phone. What we commit to: the estimate is free, the price is written and fixed, and there are no change-order surprises mid-job.
