Serving Adams, Cumberland, Dauphin, Franklin, Lancaster, Lebanon & York Counties
Air sealing is one of the most effective ways to improve your home’s energy efficiency and indoor comfort. Our professional air sealing contractors locate and seal the hidden gaps, cracks, and leaks in your attic, windows, doors, walls, and basement — the small openings that quietly drive up your energy bills.
Using advanced tools like thermal imaging, we find the leaks others miss and seal them with durable, energy-efficient materials. The result is a home that eliminates drafts, holds its temperature, and stays comfortable year-round — whether you need residential or commercial air sealing.
Sealing the leaks in your home’s envelope is one of the quickest, most cost-effective ways to improve comfort and cut energy waste.
Sealing hidden leaks stops your heated and cooled air from escaping — lowering your energy usage and shrinking your monthly bills, season after season.
We target the problem areas that let cold air pour in — delivering even, consistent temperatures throughout your home and an end to chilly, drafty rooms.
Sealing out outdoor pollutants, allergens, and excess moisture means cleaner air, better humidity control, and a lower risk of mold and mildew.
Air sealing closes the gaps and cracks in your building envelope — the outer shell that separates indoor and outdoor air. These hidden leaks let heated or cooled air escape while allowing outdoor air, moisture, and allergens to enter, causing drafts, uneven temperatures, and higher energy bills. We use advanced tools like thermal imaging to detect the leaks and seal them with durable, energy-efficient materials.
We use thermal-imaging cameras and advanced tools to pinpoint hidden leaks around windows, doors, vents, attics, and basements — so no trouble spot gets missed.
Air sealing stops leaks in the places insulation alone can’t reach, creating a complete thermal barrier that makes your existing insulation far more effective.
From the attic to the basement, we seal the trouble spots that drain your comfort and your budget — giving you a tighter, more efficient home you’ll feel right away. Explore our other insulation services →

“We had drafts we could never track down. The Cozy Penguin team used a thermal camera, found leaks around our windows and attic hatch we’d never have spotted, and sealed them all in an afternoon. The drafts are gone and our furnace runs way less. Money well spent.”Satisfied Central PA HomeownerReplace with a real customer review
