How Weatherization Keeps Spring Allergies Out of Your Maryland Home

Do you start sneezing every spring? Do your eyes itch and your nose run? If so, you may have hay fever, a seasonal allergy common in Maryland.

Allergy season in Maryland starts in late winter and lasts through spring. Pollen levels rise, making it hard for many people to breathe. But did you know your home can make allergies worse?

Weatherization assistance can help! CAC offers no-cost home upgrades that can keep pollen and other allergens out.

What Causes Spring Allergies in MD?

Spring allergies are caused by pollen. Trees, grass, and flowers release tiny pollen particles into the air. These particles can get into your nose and throat, irritate your eyes, and trigger sneezing, coughing, and congestion.

The most common Maryland allergy triggers in spring are:

1. Tree pollen – Oak, maple, birch, cedar, and pine trees release pollen in February, March, and April.
2. Grass pollen – Bermuda and timothy grass pollen tends to peak in May and June.
3. Mold spores – Wet spring weather helps mold grow, which can also cause allergies.

Symptoms of Hay Fever in Maryland

If you have seasonal allergies, you may notice:

• Sneezing a lot
• Stuffy or runny nose
• Itchy, red, or watery eyes
• Coughing or wheezing
• Feeling tired
• Allergy symptoms get worse when you spend time outside or when pollen gets into your home

When Does Pollen Season End in Maryland?

Maryland’s allergy season for many common allergens starts in February and can last until late June (though fall is ragweed season, another common allergen). The exact end depends on:

• Weather – Warm temperatures make pollen last longer.
• Wind – Windy days spread pollen farther.
• Rain – Rain helps wash pollen away (but mold can grow afterward).

How Weatherization Helps with Allergies in Maryland

Many people try to keep pollen out by closing windows. But pollen can still get inside through air leaks, dirty air filters, and poor insulation. Weatherization seals your home to block pollen, mold, and dust. CAC’s no-cost weatherization program can help by:

Sealing Air Leaks

Tiny cracks around windows, doors, and walls let pollen inside. Air sealing stops pollen from sneaking in and keeps indoor air cleaner. Together, insulation and air sealing upgrades create a more comfortable and healthy home.

Upgrading Heating & Cooling Systems

Old systems can struggle to filter dust and allergens out of the air circulating in your home. A new heating and cooling system can help keep out pollen and improve air quality.

Extra Ways to Help with Allergies at Home

Along with weatherization, try these easy tips:

• Remove shoes before entering your home
• Shower and change clothes after being outside
• Use an air purifier to remove pollen from the air
• Keep windows and doors closed on high-pollen days
• Dust and vacuum often to remove allergens

Together with weatherization upgrades, these steps can help you breathe easier this spring!
