Professional Wall Insulation Services
Improve your home's energy efficiency and comfort with our advanced wall insulation techniques. Perfect for existing homes and retrofit applications.
Walls are often the largest surface area of your home and can account for significant heat loss. In older homes or those with inadequate insulation, up to 35% of heat loss can occur through walls. For Long Island homes—particularly those built before 1980—wall insulation is often completely absent or severely inadequate, leading to high energy bills and uncomfortable living spaces.
In Climate Zone 4, where Long Island is located, the Department of Energy recommends R-13 to R-15 for exterior walls. However, many homes on Long Island have empty wall cavities or minimal insulation, resulting in R-values as low as R-2. This inadequate insulation forces your heating and cooling systems to work overtime, particularly during Long Island's cold winters and hot, humid summers.
Our wall insulation solutions include dense pack cellulose, injection foam, and other retrofit methods that work with existing wall structures without major demolition. These methods are specifically designed for the common home styles found throughout Suffolk and Nassau Counties—colonial, ranch, cape cod, and split-level homes.
Many Long Island homes were built between 1950 and 1980, when energy codes were minimal or non-existent. These homes often have:
Long Island's coastal climate creates unique wall insulation needs:
Blown-in cellulose insulation that fills wall cavities completely for maximum thermal performance.
Two-component foam injected into walls that expands to fill gaps and seal air leaks.
Traditional fiberglass batt insulation installed during new construction or major renovations.
Lower heating and cooling costs by preventing heat loss through walls.
Eliminate cold spots and drafts for consistent temperatures throughout your home.
Reduce dust, allergens, and outdoor air infiltration through properly sealed walls.
Minimize noise transmission between rooms and from outside sources.
Energy-efficient homes with proper insulation command higher market values.
Reduce your carbon footprint by using less energy for heating and cooling.
We use advanced thermal imaging cameras to identify heat loss areas, air leaks, and insulation gaps in your walls. This technology allows us to pinpoint exactly where insulation improvements are needed.
Empty wall cavities, $450/month winter heating bills
Solution: Dense pack cellulose in all exterior walls
Results: Reduction in heating costs, eliminated cold spots on north-facing bedrooms
Now: Reduced average winter bills
R-3 compressed fiberglass batts, drafty rooms
Solution: Injection foam retrofit in all exterior walls
Results: Eliminated drafts, reduction in PSEG bills, noticeably quieter interior
Comfort improved dramatically
Partial insulation, temperature differences between levels
Solution: Dense pack cellulose in uninsulated sections, topped up existing areas
Results: Uniform temperatures throughout home, reduction in summer cooling costs
All rooms now comfortable year-round
Thermal Imaging Scan
We use infrared cameras to identify heat loss patterns, air infiltration, and existing insulation gaps. This reveals exactly where insulation is missing or ineffective.
Wall Cavity Inspection
We drill small inspection holes to check for existing insulation, cavity obstructions, moisture issues, and wall construction type (2x4 vs 2x6 framing).
Material Selection
Based on your wall construction, climate concerns, and budget, we recommend either dense pack cellulose (R-3.6/inch) or injection foam (R-5.0/inch).
Project Planning
We provide detailed written estimate, timeline, and explain what to expect during installation. We coordinate interior furniture protection if needed.
Preparation & Protection
We protect landscaping, cover floors, and set up equipment. For interior work, we use containment barriers to isolate work areas and minimize dust.
Access Hole Drilling
We drill 1-inch holes at intervals (typically every 16-24 inches) in either exterior siding or interior drywall, depending on the most practical approach for your home.
Insulation Installation
Dense pack cellulose is blown in at 3.5 lbs/cubic foot density, or injection foam is applied as a two-part liquid that expands to fill the entire cavity, including around wiring and plumbing.
Cavity Verification
We monitor fill density to ensure complete coverage. For dense pack, we check for firmness; for injection foam, we verify proper expansion without overfill.
Hole Patching & Finishing
All access holes are plugged and sealed. Exterior siding holes are caulked and painted to match. Interior drywall holes are patched, sanded, and primed, ready for your finish painting.
Final Inspection & Cleanup
Post-installation thermal imaging confirms complete coverage. We thoroughly clean all work areas, removing equipment and debris, leaving your home cleaner than we found it.
