Spray Foam Insulation
Seal, Save & Stay Comfortable All Year Round
Energy loss in a home doesn’t just increase bills — it reduces comfort. With professional spray foam insulation, Coastal HVAC Specialist helps you seal air leaks, increase energy efficiency, and improve indoor comfort throughout the year. Spray foam fills gaps and cracks that traditional insulation can’t reach, preventing heat loss in winter and blocking hot air during summer. Our experienced team installs high-performance insulation for attics, basements, crawl spaces, garages, and new construction projects.

Energy Efficiency That Pays You Back
Spray foam insulation offers one of the best returns on investment for homeowners. Its airtight sealing ability stops conditioned air from escaping and eliminates drafts, hot spots, and cold corners. Our technicians use premium residential and commercial-grade foam that expands to fill every corner — walls, ceilings, attic floors, rim joists, or crawl spaces.
Whether you’re renovating an older home or insulating a new build, our team ensures correct installation thickness, precision application, and long-lasting performance. If your existing insulation has degraded, caused moisture issues, or isn’t delivering comfort, we can inspect and upgrade your insulation to a more efficient spray foam solution.
