If you’re sneezing more indoors than outside this spring, your attic might be the unexpected source of your allergy flare-ups.
While we tend to blame pollen from trees and flowers for seasonal allergies, the truth is that poor attic insulation and air sealing can trap allergens inside your home — and even invite new ones in.
Here are three ways your attic insulation could be contributing to your allergy symptoms this spring — and how to fix it.

Over time, insulation breaks down and collects dust, pollen, rodent droppings, and other debris — especially if your attic hasn’t been inspected or updated in years. Every time your HVAC system kicks on, those particles can get stirred up and circulated throughout your home.
If your insulation looks discolored, compressed, or has a musty smell, it’s likely past its prime — and potentially harmful to your indoor air quality.
The Fix:
Comfort 1st Insulation can remove old or contaminated insulation and replace it with clean, energy-efficient options like blown-in cellulose or spray foam, which also offer better air sealing.
Most attics aren’t airtight. Tiny cracks, gaps, and poorly sealed ducts create what’s known as the stack effect — where warm air rises and escapes through the attic, pulling in outdoor air (and allergens) through the lower parts of your home.
During spring, that means more pollen, dust, and pollutants are being pulled right into your living spaces.
The Fix:
Let Comfort 1st Insulation perform an air leakage test and seal gaps around light fixtures, ductwork, and other attic penetrations. Sealing your attic is one of the most effective ways to improve air quality and energy efficiency.
Spring’s humidity, rain, and snowmelt can leave moisture in your attic. If insulation gets wet and doesn’t dry properly, it becomes the perfect breeding ground for mold and mildew — two of the biggest allergy triggers.
You might not see mold directly, but you’ll definitely feel its effects: stuffy noses, watery eyes, and respiratory irritation.
The Fix:
Have Comfort 1st Insulation check for roof leaks, proper attic ventilation, and signs of moisture buildup. If mold is found, it’s crucial to remove it safely, replace affected insulation, and address the source of the moisture.
