Air Sealing Contractor

Seal the Leaks. Save Energy. Improve Comfort.

Air leaks are one of the biggest causes of energy loss in homes—often more impactful than insulation alone. At Atlantic Insulation, Inc., our professional air sealing services close the hidden gaps and cracks that allow conditioned air to escape and outdoor air to sneak in.

The result is a more comfortable home, lower energy bills, and improved indoor air quality year-round.

Why Air Sealing Is So Important

Even well-insulated homes can suffer from poor performance if air leaks are left untreated. Small openings around framing, wiring, plumbing, and attic access points can add up to significant energy loss.

Proper air sealing helps to:

• Reduce heating and cooling costs by minimizing wasted energy
• Eliminate drafts and hot or cold spots
• Improve comfort in every season
• Reduce moisture intrusion and help prevent mold and rot
• Improve indoor air quality by limiting outdoor pollutants
• Increase the effectiveness of insulation systems

Air sealing is especially important in attics, crawlspaces, rim joists, and older homes.

Professional Attic & Crawlspace Cleaning and Decontamination Service

The condition of an attic or crawlspace plays an important role before new insulation is installed. Atlantic Insulation, Inc. now provides professional sanitizing and decontamination services using commercial-grade battery-powered spray equipment along with Benefect Decon 30.

Unlike traditional harsh chemical treatments, Benefect Decon 30 is a botanical-based disinfectant formulated with natural thyme oil and contains no bleach or strong synthetic fumes. Its gentler formulation often allows treatments to be completed without requiring occupants to leave the property during application.

This added service helps treat contamination caused by rodents, moisture problems, mold and mildew exposure, bacteria, odors, and years of dust and debris buildup, creating a cleaner space before new insulation is installed.

Why Add a Sanitizing Treatment?

Attics and crawlspaces are commonly affected by:

• Rodent droppings and nesting debris
• Persistent musty odors
• Mold and mildew growth on surfaces
• Bacteria and other harmful microorganisms
• Dust and airborne particles
• Organic buildup caused by years of poor ventilation

Sanitizing these areas before installing insulation helps create a cleaner environment, improves overall indoor cleanliness, and helps protect the homeowner’s investment in the property.
