Attic Air Sealing
Seal cracks and leaks in your attic to stop unwanted airflow and lower your heating and cooling costs — while improving comfort room to room. Attic air sealing targets hidden gaps around top plates, recessed lights, and ceiling fixtures to greatly reduce the stack effect and energy waste.
About This Service
Attic air sealing targets the specific areas where conditioned air escapes into the attic — including top plates, recessed lighting, and ceiling fixtures. These small, often invisible gaps are a major contributor to the stack effect, which pulls air up and out of your home year-round.
By sealing these openings with spray foam, caulk, and durable materials, we help reduce energy waste, support HVAC performance, and stabilize indoor temperatures.
When paired with attic insulation, attic air sealing becomes one of the most impactful ways to boost whole-home efficiency.

Frequently Asked Questions
Does air sealing qualify for rebates?
Yes. Air sealing often qualifies for utility rebates and local energy efficiency programs, and we’ll guide you through the application process to make sure you get every dollar available.
How do you find the air leaks?
We use blower door testing and infrared scanning to locate invisible leaks in ceilings, foundations, and walls. This diagnostic approach ensures no air leak goes unnoticed.
How long does the process take?
Most homes can be fully sealed in a day or less, depending on the size and complexity of the job. Results are felt immediately.
What is air sealing and why is it important?
Air sealing closes gaps and cracks that let conditioned air escape, improving comfort, reducing utility bills, and supporting overall home energy performance.
What materials are used to seal air leaks?
We use a combination of caulk, spray foam, gaskets, and weatherstripping, depending on where and how the leak occurs.
