High-Performance Insulation & Air Sealing

Whether you're experiencing rooms that are freezing cold in the winter and boiling hot in the summer, uneven temperatures between floors, an HVAC system that never shuts off, or a combination of these issues, we can help. We don't just throw standard fiberglass over a problem. We offer a full catalog of specialized residential and commercial insulation solutions designed to target energy loss from the roofline down to the foundation.

Our insulation services in Johns Island:

• Attic Insulation & Upgrades: We stop the baking sun from heating up your ceiling joists and radiating heat down into your bedrooms. We use premium, fire-resistant, and pest-deterrent materials to create a dense thermal barrier.
• Blown-In Cellulose Insulation: Perfect for older or under-insulated homes. Blown-in cellulose fills every irregular gap and corner of your attic floor, maximizing your R-value and instantly reducing the strain on your heating and cooling equipment.
• Spray Foam Insulation: The absolute gold standard for home efficiency. Closed-cell spray foam expands to fill every crack, cavity, and void—providing a superior thermal barrier and a permanent air seal in a single application.
• Crawl Space Insulation: If your floors feel cold in the winter or you notice a musty odor downstairs, your crawl space is working against you. We insulate your crawl space to seal out damp, humid earth air so you breathe cleaner, dryer air.
• Commercial Spray Foam & Specialty Insulation: We don't just serve homeowners. For business owners, property managers, and commercial builders in Johns Island and nearby areas, our commercial-grade spray foam applications deliver unmatched structural strength, moisture control, and significant overhead cost reductions for large facilities.
• Patented SuperAttic™ System: For homeowners who use their attics for storage or have HVAC equipment up there, standard floor insulation isn't enough. Our exclusive SuperAttic™ system fastens rigid foam insulation directly to the underside of your roof rafters, bringing your attic into the conditioned space of your home.
• Ductwork Sealing & Encapsulation: Up to 30% of your conditioned air can leak out of hard duct lines before it ever reaches your rooms. We wrap, seal, and insulate your ductwork with spray foam to ensure pure, temperature-controlled air goes exactly where it belongs.
• Wall, Basement, & Garage Insulation: From injection foam into existing exterior walls to rigid foam board barriers on conductive concrete basement walls, we ensure no side of your home is leaking money. 

Solatube® Daylighting Systems

Do you have dark, gloomy kitchens, bathrooms, or closets where you always have to turn on electric lights, but you don't want the leaks, cost, or heat of a traditional skylight? A daylighting system might be the answer. Solatube is a revolutionary system that captures natural sunlight on your roof and funnels it into virtually any room through a highly reflective, leakproof tube.

Benefits of daylighting system installation in Johns Island:

• Leak-proof design that fits perfectly into any roof.
• Fast, same-day installation with no major structural remodeling required.
• Energy-efficient and eco-friendly lighting for dark hallways, kitchens, and bathrooms.

Solar Star® Attic Fans

An attic space can act like a giant heater sitting on top of your house, forcing your upstairs AC unit to work double-time. Your attic can easily climb past 140°F during the summer. Our solar attic fans actively pull the superheated air out of your home, allowing it to cool down naturally.

Benefits of solar attic fan installation in Johns Island:

• Reduces upstairs room temperatures significantly.
• Prevents moisture buildup that causes mold and roof deck rot.
• Operates on 100% free solar energy—no added electricity costs!
