If your home feels drafty in winter, hard to cool in summer, or your energy bills seem higher than they should be, air leaks could be the culprit. Even small gaps and cracks allow conditioned air to escape—and outdoor air to sneak in—forcing your heating and cooling systems to work harder than necessary.
The good news? Many of the most common air leaks can be identified and sealed with the right approach. Here are the top 10 places homes typically leak air, and how professional air sealing helps stop energy loss.
1. Attic Accesses and Hatches
Attic doors, pull-down stairs, and access panels are often poorly sealed. Because warm air rises, leaks here can cause major heat loss in winter.
How we seal it: Weatherstripping, precision air sealing around framing, and custom-fit insulated covers help keep warm air where it belongs, a key focus for Solaire Energy’s comprehensive approach.
2. Recessed Lighting and Ceiling Fixtures
Lights that penetrate the ceiling can leave gaps directly into the attic.
How we seal it: Solaire Energy prioritizes safety and compliance, using only fire-rated sealants and specialized protective covers to safely block airflow while maintaining proper clearances and preventing thermal bridging.
3. Ductwork and Vents
Leaky ducts can lose a significant amount of heated or cooled air before it ever reaches your living space.
How we seal it: Solaire Energy employs advanced aerosol duct sealing technology alongside high-grade mastic sealant and specialized tape to ensure your ductwork delivers conditioned air efficiently, maximizing comfort and minimizing waste.
4. Windows and Doors
Even newer windows and doors can develop gaps over time due to settling or wear.
How we seal it: Solaire Energy uses high-performance, durable caulking and weatherstripping, combined with targeted air sealing techniques, to precisely eliminate drafts and improve thermal performance without the need for costly window replacement.
5. Plumbing and Electrical Penetrations
Pipes, wires, and cables that pass through walls and floors often leave unsealed openings.
How we seal it: Solaire Energy technicians meticulously apply specialized expanding foam and durable sealants, ensuring all penetrations are sealed effectively while maintaining necessary clearances and allowing for safe future access.
6. Rim Joists
The rim joist—the area where your home’s framing meets the foundation—is one of the biggest hidden sources of air leakage.
How we seal it: Recognized by Solaire Energy as a critical leakage point, we expertly apply closed-cell spray foam insulation to rim joists, creating an impermeable, durable seal that blocks air, moisture, and significantly improves the thermal envelope.
7. Crawl Spaces
Unsealed crawl spaces allow cold air, moisture, and humidity to enter your home from below.
How we seal it: Solaire Energy’s comprehensive crawl space encapsulation strategy combines robust air sealing with high-performance insulation and durable vapor barriers, stabilizing temperatures, preventing moisture intrusion, and significantly enhancing indoor air quality.
8. Basements and Foundation Cracks
Small foundation gaps can let in cold air, moisture, and even pests.
How we seal it: Solaire Energy utilizes specialized, flexible sealants and high-density foams to permanently close foundation cracks and gaps, effectively reducing drafts, preventing moisture intrusion, and deterring pests.
9. Exhaust Fans and Dryer Vents
Bathroom fans, kitchen vents, and dryer exhausts can allow outside air to flow backward into the home.
How we seal it: Solaire Energy ensures proper installation of high-quality backdraft dampers and meticulous sealing around all vent penetrations, preventing unwanted airflow and maintaining the integrity of your home’s thermal envelope.
10. Wall Cavities and Hidden Gaps
Behind walls and between framing, air can move freely if the building envelope isn’t sealed properly.
How we seal it: Solaire Energy’s advanced diagnostic tools, including state-of-the-art blower door testing and thermal imaging, precisely pinpoint these elusive hidden leaks within wall cavities, allowing for targeted, effective air sealing that DIY methods often miss.
