Professional Attic Insulation Services
Prevent heat loss and ice dams with proper attic insulation. Reduce energy bills by up to 40% with our professional insulation services.
Your attic is the most important area to insulate in your home. Up to 40% of heat loss occurs through an inadequately insulated attic, making it the primary source of energy waste in most Long Island homes. In Suffolk and Nassau County, where winter temperatures regularly drop below freezing and summer heat can push attic temperatures above 140°F, proper attic insulation is essential for both comfort and energy efficiency.
Proper attic insulation creates a thermal barrier that keeps warm air inside during winter and hot air out during summer, significantly reducing your energy bills while improving home comfort year-round. For homes in Climate Zone 4 (which includes all of Long Island), the Department of Energy recommends R-49 to R-60 insulation in attics— significantly more than older homes typically have.
Beyond energy savings, proper attic insulation prevents ice dams that plague Long Island homes during winter storms, protects your roof and ceiling from damage, reduces strain on HVAC systems, and creates a more consistent, comfortable temperature throughout your home. Whether you're in a 1950s ranch in Smithtown or a newer colonial in East Hampton, upgrading your attic insulation delivers immediate, measurable benefits.
Long Island's coastal climate and mix of older housing stock create specific attic insulation challenges. Here are the most common issues we encounter:
One of the most destructive winter problems on Long Island. When warm air escapes through inadequate insulation, it melts snow on your roof. The water runs down to the cold eaves and refreezes, creating ice dams that back up under shingles, causing water damage, rot, and expensive repairs. Proper attic insulation combined with air sealing keeps your roof cold and prevents ice dam formation entirely.
Long Island attics can reach 140-160°F on summer days. Without sufficient insulation, this intense heat radiates down into living spaces, forcing your AC to work overtime. Older homes with minimal or settled insulation are particularly vulnerable. Upgrading to R-49 or higher dramatically reduces heat transfer and can cut cooling costs by 30-40%.
High humidity from our coastal location combined with temperature differences creates condensation in poorly insulated attics. This moisture leads to mold growth, wood rot, and reduced insulation effectiveness. Proper insulation installation includes vapor barriers and ventilation improvements to control moisture and protect your home's structure.
Many Long Island homes built before 2000 have inadequate attic insulation—often just R-19 or R-30 when R-49 is recommended. Additionally, older fiberglass insulation compresses over time, losing up to 50% of its R-value. If your home is more than 20 years old and has never had insulation upgraded, you're likely wasting significant energy and money.
Eco-friendly recycled material. Great for covering irregular spaces. R-value of 3.2-3.8 per inch.

Reduce heating and cooling costs by up to 40% with proper attic insulation.
Stop ice dam formation by keeping your roof cold and eliminating hot spots.
Maintain consistent temperatures throughout your home year-round.
Reduce strain on heating and cooling systems, extending their lifespan.
Energy-efficient homes with proper insulation command higher resale values.
Reduce your carbon footprint by using less energy for heating and cooling.
Long Island is in Climate Zone 4, which requires specific R-values for optimal energy efficiency:

Note: R-value measures thermal resistance. Higher R-values provide better insulation performance.

We follow a comprehensive process to ensure your attic insulation is installed correctly and delivers maximum energy savings and comfort.
We thoroughly inspect your attic to assess current insulation levels, identify air leaks, check for moisture or mold issues, evaluate ventilation, and determine the best insulation solution. We'll measure existing R-values and provide recommendations to reach R-49 or R-60 as appropriate for your home.
Timeline: 1-2 hours | Free service
Before installing insulation, we seal air leaks around chimneys, pipes, wiring penetrations, and recessed lights. This critical step prevents warm air from escaping and maximizes insulation effectiveness. We also ensure proper ventilation baffles are in place to maintain airflow from soffit vents.
Timeline: 2-4 hours | Essential for ice dam prevention
Using professional equipment, we blow in cellulose or fiberglass insulation to achieve the target R-value (typically R-49 to R-60 for Long Island homes). We ensure even coverage depth throughout the attic, mark depth with rulers for future reference, and maintain proper clearances around vents and electrical fixtures.
Timeline: 3-6 hours | Most projects completed same day
We verify uniform insulation depth, ensure all areas are properly covered, confirm ventilation is not blocked, and document the installation with photos. Complete cleanup includes removing all equipment, vacuuming work areas, and disposing of any old insulation if removed.
