At Luas Insulation & Energy Consulting, air sealing is a critical service we provide to complement our insulation installations, ensuring your home or business achieves maximum energy efficiency and comfort. In Louisiana's hot, humid climate, uncontrolled air leakage can account for up to 30-40% of energy loss, driving up utility bills and straining your HVAC system. Our professional air sealing targets hidden gaps, cracks, and penetrations that allow conditioned air to escape and outdoor air to infiltrate.  When you add all these cracks together, the hole can end up being substantial, so the more we find, the better your home will respond.

We start with a thorough assessment, often combining air sealing with blower door testing to identify leaks precisely. Common areas we address include attics, basements, crawl spaces, walls, windows, doors, electrical outlets, plumbing penetrations, and recessed lighting.
 
Our methods use high-quality, durable materials tailored to each situation:
 

• Caulk and Sealants — For small cracks around windows, doors, trim, and baseboards.

• Weatherstripping — Applied to doors and operable windows for a tight seal against drafts.

• Expanding Spray Foam — Ideal for larger gaps, electrical boxes, plumbing pipes, and rim joists—providing both air sealing and minor insulation.

• Rigid Foam and Tape — For sealing around chimneys, ducts, and attic hatches.

Benefits of our air sealing services include:

• Significant reduction in heating and cooling costs (often 10-20% savings)

• Improved indoor comfort by eliminating drafts and hot/cold spots

• Better indoor air quality by reducing pollen, dust, and humidity infiltration

• Enhanced durability of your insulation and roof structure

• Potential eligibility for energy rebates from Entergy or federal programs

We perform air sealing for both residential homes and commercial buildings, always with minimal disruption and a clean worksite. Our team follows best practices from Building America and ENERGY STAR guidelines, ensuring long-lasting results backed by our satisfaction guarantee.

As part of our whole-home approach, we recommend pairing air sealing with insulation upgrades and attic ventilation (like solar attic fans) for optimal performance.
