Houston Spring Pollen: Cleaning Your Home's Exterior

By the Peak Clean team · October 13, 2026

Every spring, Houston homes get coated in a yellow-green film of pollen, on windows, patios, cars, and siding. It looks bad, and cleaning at the wrong time means doing it all over again.

What pollen does to your exterior

• Coats windows and leaves them dull and hazy
• Settles on siding, patios, and outdoor furniture
• Mixes with rain into a sticky film that's harder to wipe off
• Clogs gutters and builds up on window tracks and screens

When to clean

Tree pollen is heaviest from late winter through spring. If you clean in the middle of it, the film comes back in days. Many homeowners get better results cleaning windows and surfaces after the heaviest pollen has passed.

A simple seasonal rhythm

• After spring pollen: windows, screens, tracks, and patios
• Late spring or summer: house washing to remove algae that spring moisture feeds
• Before the holidays: windows again, plus gutters after fall leaves

Don't forget screens, tracks, and gutters

Pollen collects in window tracks and on screens, and it washes into gutters where it mixes with debris. A thorough window cleaning that includes frames, sills, tracks, and screens helps keep pollen from just blowing back onto clean glass.

Allergy note

If someone in your home is sensitive to pollen, a clean exterior and regularly cleaned screens and tracks can mean less of it settling around doors and windows. It's not a medical fix, but it can help the area around your home feel cleaner.
