Professional Blown-In Insulation Services
Efficient and cost-effective blown-in insulation solutions. Choose between eco-friendly cellulose or fiberglass for superior coverage and performance.
Blown-in insulation is a loose-fill material that's pneumatically installed into attics, walls, and other enclosed spaces. Using specialized blowing equipment, the insulation fills every nook and cranny for complete coverage and superior thermal performance. This method is particularly effective for Long Island homes where irregular framing, electrical wiring, and plumbing create gaps that traditional batt insulation cannot fill.
Available in cellulose and fiberglass options, blown-in insulation is ideal for retrofit applications and can achieve higher R-values than traditional batt insulation. For Long Island's Climate Zone 4, the Department of Energy recommends R-49 to R-60 in attics and R-13 to R-15 in walls—targets easily achieved with blown-in methods.
Cellulose blown-in insulation offers R-3.2 to R-3.8 per inch, while fiberglass provides R-2.2 to R-2.7 per inch. Both options significantly outperform the minimal or absent insulation found in many Long Island homes built before 1980. The dense-pack application method ensures complete cavity fill, eliminating air gaps that reduce insulation effectiveness and allow drafts.
The majority of Long Island homes were built when energy efficiency wasn't a priority. Colonial, ranch, and cape cod homes from the 1950s-1970s typically have empty or inadequately insulated wall cavities and attics with minimal fiberglass batts. Blown-in insulation allows us to add substantial R-value without demolishing walls or disrupting your living space. We simply drill small access holes, blow in the insulation, and patch the holes—typically completing a full house in 1-2 days.
Long Island's coastal winds create significant air infiltration in poorly sealed homes. Blown-in cellulose, in particular, conforms to irregular shapes and fills around wiring, plumbing, and framing members, creating an effective air barrier. This reduces drafts around outlets, windows, and doors—common complaints in older Long Island homes. Dense-pack cellulose at 3.5 lbs/cubic foot density provides excellent resistance to air movement while still allowing vapor transmission to prevent moisture buildup.
Long Island's climate demands insulation that performs well in both heating and cooling seasons. Winter temperatures regularly drop into the teens, while summer attic temperatures can exceed 140°F. Blown-in insulation maintains consistent R-value year-round and won't compress or settle like some batt insulation. Cellulose's higher density also provides better resistance to heat flow, keeping your home cooler in summer and warmer in winter.

Initial Inspection
Measure existing insulation levels, check for moisture issues, and inspect ventilation. We identify any pest activity, mold, or structural concerns that need addressing before insulation.
Air Sealing
Before blowing insulation, we seal major air leaks around chimneys, plumbing stacks, electrical wires, and attic access hatches. This critical step prevents air leakage that undermines insulation effectiveness.
Ventilation Protection
Install baffles at soffit vents to maintain proper attic ventilation while preventing insulation from blocking airflow. Proper ventilation is essential for preventing ice dams and moisture buildup.
Access & Protection Setup
Set up ladders and access equipment. Protect floors, furniture, and landscaping with drop cloths. Position insulation blowing machine and run hoses to work areas.
Blowing Equipment Setup
Load insulation material into hopper. Calibrate machine for proper density (3.5 lbs/cu ft for dense-pack, 1.5 lbs/cu ft for attic loose-fill). Run hose to installation area.
Systematic Application
For attics: Blow insulation evenly across entire floor, working from perimeter to center. Use rulers to verify depth and achieve target R-value. For walls: Dense-pack through access holes, filling from bottom to top.
Depth & Density Verification
Continuously check insulation depth with marked rulers. For R-60, we target 16-17 inches of cellulose or 20-22 inches of fiberglass. Dense-pack walls are verified by feel and resistance.
Final Coverage Check
Walk entire attic to verify uniform coverage. Add material to any low spots. Ensure no insulation is touching recessed lights or blocking ventilation paths.
Cleanup & Patching
Remove equipment and clean all work areas. Patch and paint any access holes in walls. Vacuum any dust or debris. Install insulation information labels showing R-value and installation date.
Final Walkthrough
Review completed work with homeowner. Explain proper maintenance and care. Provide documentation including R-value achieved, material specifications, and warranty information.
