Best Attic Air Sealing Services

Attic air sealing closes gaps and penetrations where conditioned indoor air escapes into the attic or outside air enters the home. Common leak points include plumbing stacks, wiring holes, recessed lights, attic hatches, top plates, and duct chases. Sealing these areas helps reduce drafts, improve temperature consistency, and make insulation perform more effectively.

Many homes benefit from attic air sealing if they have uneven room temperatures, high utility bills, drafts, dusty rooms, or insulation that is underperforming. A home energy audit or attic inspection can identify leakage paths and prioritize the most important areas. Greenify Energy Savers looks at the attic as part of the whole home energy system.

Attic air sealing can reduce energy waste by limiting the amount of heated or cooled air lost through the top of the home. While savings vary by home condition, HVAC system, insulation levels, and leakage severity, sealing is often one of the most effective upgrades because it improves comfort and helps existing insulation work as intended.

Air sealing and insulation work best together, but they solve different problems. Air sealing blocks unwanted airflow through gaps and cracks, while insulation slows heat transfer. If insulation is added before leaks are sealed, air can still move through or around it. That is why attic air sealing is often recommended before insulation upgrades.

Common materials include expanding foam, caulk, rigid blocking, weatherstripping, and approved sealants designed for specific attic conditions. The right material depends on the location, gap size, nearby heat sources, and building requirements. Technicians also avoid sealing areas that require ventilation, such as soffit pathways, to maintain proper attic airflow.

A typical attic air sealing project can often be completed in one day, depending on attic size, accessibility, the number of leak points, and whether related upgrades are performed. Larger or more complex homes may require additional time. An inspection helps establish the scope and ensures the work targets the most important leakage areas.

Yes. Attic air sealing frequently improves comfort by reducing drafts, temperature swings, and air movement between living spaces and the attic. It can help upstairs rooms feel more stable and reduce the workload on heating and cooling equipment. For best results, it is often paired with adequate insulation and proper attic ventilation.
