WeatherFoam Insulation

WeatherFoam Insulation serves Mt Sinai and surrounding Long Island communities as a specialized insulation contractor with a perfect 5-star rating across 86 reviews. The company focuses on injectable wall foam solutions, helping homeowners address drafts, moisture intrusion, and energy inefficiency through exterior wall injection insulation. Their residential services include attic insulation, air sealing, basement and crawl space insulation, and garage insulation projects.

What distinguishes WeatherFoam is their injectable wall foam system, which allows them to insulate existing walls without major demolition. The company also handles fiberglass batt insulation, commercial masonry foam applications, and rodent remediation to seal entry points and restore compromised insulation. Their air sealing work targets both exterior envelopes and hidden cavities discovered during renovation projects.

Reviewers consistently mention technician Joe and his team members Christian, Danilo, and Santiago. One homeowner described how the crew accommodated a tight remodeling timeline, completing extensive exterior and interior air sealing plus attic insulation in a single day. Another reviewer noted the team stayed late to ensure a job was finished properly, with technicians taking pride in their work. A customer with an uninsulated garage that was nearly unusable year-round reported immediate comfort improvements after a one-day installation.
