Professional Spray Foam Installation
The most effective insulation solution for maximum energy savings. Superior R-value, air sealing, and moisture control in one application.
Spray foam insulation is a high-performance insulation material that expands upon application, creating an airtight seal that effectively blocks heat transfer, air infiltration, and moisture. It's the gold standard for energy efficiency and home comfort, particularly effective in Long Island's Climate Zone 4 conditions where temperature extremes require superior thermal protection.
Available in two types—closed-cell and open-cell—spray foam provides superior insulation performance compared to traditional fiberglass or cellulose, often reducing energy bills by 40% or more. For Long Island homeowners facing harsh winter temperatures and humid summer conditions, spray foam's ability to create a complete air and moisture barrier makes it particularly valuable.
In Suffolk and Nassau County homes, spray foam insulation addresses multiple challenges simultaneously: preventing ice dams during winter storms, controlling humidity during summer months, blocking allergens year-round, and significantly reducing HVAC workload. Whether you own a classic colonial in Huntington, a ranch-style home in Islip, or a cape cod in Babylon, spray foam insulation delivers unmatched performance and energy savings.
Long Island's unique coastal climate presents specific challenges that make spray foam insulation particularly effective. Our region experiences temperature swings from below freezing in winter to 90°F+ in summer, combined with high humidity from our proximity to the Atlantic Ocean and Long Island Sound.
Spray foam insulation solves these challenges by creating a continuous thermal and moisture barrier that adapts to Long Island's demanding climate. With proper installation, homeowners typically see 30-50% reductions in energy consumption, along with dramatically improved comfort and indoor air quality.
| Feature | Closed-Cell | Open-Cell |
|---|---|---|
| R-Value per inch | R-6 to R-7 | R-3.5 to R-4 |
| Density | 2.0 lbs/cubic ft | 0.5 lbs/cubic ft |
| Moisture Barrier | Yes | No |
| Air Barrier | Yes | Yes |
| Structural Support | Adds rigidity | Minimal |
| Cost | Higher | Lower |
| Best For | Exterior walls, basements, crawl spaces | Interior walls, attics (with proper ventilation) |
Highest R-value per inch means maximum thermal protection and lower energy bills year-round.
Expands to fill every crack and gap, eliminating drafts and air infiltration that wastes energy.
Closed-cell foam acts as a moisture barrier, preventing mold growth and water damage.
Won't settle, sag, or lose effectiveness over time. Lasts the lifetime of your home.
Excellent sound dampening properties reduce noise transmission between rooms and from outside.
Closed-cell foam adds rigidity to walls and can increase structural strength.
Attics
Basements
Crawl Spaces
Rim Joists
Exterior Walls
Commercial Buildings
Unlike traditional insulation materials that settle, compress, or deteriorate over time, spray foam insulation maintains its effectiveness for the lifetime of your home—typically 80+ years. This exceptional lifespan makes it one of the most cost-effective insulation investments available.
In Long Island's challenging climate with temperature extremes, salt air exposure, and high humidity, spray foam's durability becomes even more valuable. While the upfront investment is higher than traditional materials, the combination of energy savings, maintenance-free operation, and lifetime performance typically results in payback within 3-7 years through reduced energy costs alone.

Professional installation is critical for spray foam performance. Our certified technicians follow a detailed process to ensure optimal results and your complete satisfaction.
We assess your property, discuss your needs, and provide a detailed estimate with recommendations. During this visit, we'll identify problem areas, measure spaces, and determine the best spray foam solution for your specific situation.
Comprehensive home energy assessment using thermal imaging and blower door testing to identify all areas where insulation improvements will have the most impact. We'll create a prioritized plan based on your budget and energy-saving goals.
Proper preparation ensures optimal adhesion and performance. We protect surrounding areas with plastic sheeting, mask off fixtures and vents, clean surfaces, and address any moisture issues before application begins.
Our certified technicians apply spray foam using state-of-the-art equipment calibrated for Long Island's climate. We apply foam in multiple passes to achieve the proper thickness and R-value, ensuring complete coverage without gaps or voids.
Spray foam cures and becomes inert within 24 hours. We ensure proper ventilation during this period and verify that all areas are properly sealed. The space should remain unoccupied during the curing process.
We inspect all work to ensure proper thickness, coverage, and performance standards are met. We use thermal imaging to verify complete air sealing and document the installation for your records.
Complete cleanup of all work areas, removal of protective coverings, and a final walkthrough to ensure your complete satisfaction. We'll explain care and maintenance (minimal) and answer any remaining questions.
Most residential spray foam projects are completed within 1-2 days from start to finish. Larger homes or complex installations may require 2-3 days. We'll provide a detailed timeline during your free consultation and work efficiently to minimize disruption to your daily routine.
We provide professional spray foam insulation services to homeowners and businesses across Long Island.
