As temperatures rise in the Midlands, summer brings longer days, high humidity—and unfortunately, an increase in airborne allergens and unwanted pests. While many homeowners ramp up their cleaning routines or turn to chemical solutions, there’s a better, longer-lasting way to protect your home: air sealing.

At Koala Insulation of the Midlands, we specialize in helping homeowners create healthier, more comfortable living environments year-round. In this blog, we’ll explore how air sealing your home can keep summer allergens and pests at bay, improve energy efficiency, and enhance indoor air quality.

What Is Air Sealing?

Air sealing is the process of identifying and closing gaps, cracks, and openings in a home’s exterior and interior building envelope. These small leaks—commonly found around windows, doors, attics, crawl spaces, and ductwork—may seem insignificant, but they can have a big impact on comfort, air quality, and even your utility bills.

Common air leakage points:

• Attic access points
• Recessed lighting
• Plumbing penetrations
• Electrical outlets
• Window and door frames
• Baseboards and trim
• Duct connections

By professionally sealing these areas, Koala Insulation of the Midlands helps prevent unwanted airflow, moisture intrusion, and access for insects and airborne irritants.

How Air Sealing Helps Block Summer Allergens

1. Reduces Outdoor Air Infiltration

During the summer, outdoor air is filled with pollen, dust, and mold spores—all of which can easily make their way inside through tiny cracks in your home’s structure. If your home isn’t sealed properly, allergens can infiltrate your indoor space, triggering allergy and asthma symptoms.

Air sealing stops this unfiltered air from entering, significantly improving indoor air quality and reducing the presence of airborne irritants. This is especially helpful for:

• Allergy sufferers
• Children and elderly residents
• Those with respiratory conditions like asthma

2. Controls Humidity and Mold Growth

Summer in the Midlands comes with high humidity. When warm, moist air seeps into your home through unsealed gaps, it raises indoor humidity levels and creates the perfect breeding ground for mold and mildew.

By sealing your home’s envelope, you:

• Reduce excess moisture
• Prevent mold spores from spreading
• Protect walls, insulation, and furniture from mildew damage

Koala Insulation of the Midlands often combines air sealing with high-performance insulation to help maintain ideal humidity levels throughout your home.

3. Keeps Air Filters and HVAC Cleaner

When outdoor allergens sneak into your home, your HVAC system works harder to trap and filter them out. This leads to:

• More frequent filter replacements
• Higher HVAC maintenance costs
• Reduced system efficiency

Sealing your home helps keep allergens out in the first place, so your air filters and ducts stay cleaner—and your HVAC system runs more efficiently all summer long.

How Air Sealing Deters Summer Pests

In addition to allergens, summer also brings a surge in insects and small critters looking for cool, shaded environments. Unsealed gaps in your home act like welcome mats for these unwanted guests.

1. Blocks Entry Points for Insects

Gaps around doors, windows, attic vents, and baseboards offer easy access for:

• Ants
• Spiders
• Mosquitoes
• Roaches
• Silverfish

By professionally sealing your home, you eliminate these entry points and significantly reduce the likelihood of indoor infestations.

2. Deters Rodents and Larger Pests

Small rodents like mice and squirrels can squeeze through holes the size of a coin. Attics and crawl spaces are especially vulnerable.

With air sealing and insulation upgrades from Koala Insulation of the Midlands, your home becomes a less appealing and less accessible target for these pests.

3. Prevents Nesting in Insulation and Ducts

Unsealed homes invite pests to nest in warm, dark areas—like behind insulation or inside air ducts. These nests can lead to:

• Contaminated insulation
• Damage to ductwork
• Foul odors and droppings

Sealing these hidden areas ensures your home remains clean, safe, and pest-free during the most active summer months.

Energy Efficiency Bonus: Save While You Stay Protected

While the focus of this blog is on allergens and pests, it’s worth mentioning one of the best side effects of air sealing: lower energy bills.

When you seal up leaks in your attic, walls, and floors, you prevent cooled air from escaping and hot air from entering. That means:

• Your air conditioner works less
• Indoor temperatures remain more stable
• You reduce your carbon footprint
• You enjoy greater comfort for less money

Pairing air sealing with insulation improvements from Koala Insulation of the Midlands can deliver even more impressive results—both in savings and comfort.

Signs Your Home May Need Air Sealing

• Drafts near windows and doors
• Hot or cold spots in rooms
• Higher-than-usual energy bills
• Musty smells or signs of mold
• Frequent pest sightings
• Allergy symptoms that worsen indoors

If any of these sound familiar, it’s time for a professional inspection.
