Wake County Pollen Season: When to Wash Your House, Windows, and Deck

Everyone who has lived through a Triangle spring knows the yellow film. Cars turn green-gold overnight, porches need sweeping daily, and the whole county sneezes for six weeks. If you are planning exterior cleaning, the pollen calendar should decide your timing.

The Wake County pollen calendar

Late February through mid-March: tree pollen begins, mostly cedar, maple, and juniper. Fine and mostly invisible.

Late March through early May: pine pollen, the yellow stuff. This is the heavy visible season, and it coats every horizontal surface in the county.

Mid-May onward: pine tapers off and grass pollen takes over. Grass pollen is a bigger allergy problem but far less visible on surfaces.

The mistake: washing too early

The instinct when the yellow first appears is to wash immediately. If you wash your house in early April, you will be looking at a fresh yellow coat within days, and you will have paid for a cleaning the pollen erased.

The better play is to wait until the heavy pine pollen breaks, usually the first half of May in this area, then wash. You get a clean house heading into summer instead of a clean house for four days.

The exception is windows. Pollen bonded onto glass by rain and sun gets progressively harder to remove and can etch over time. If your windows are badly coated, cleaning them mid-season is worth it even knowing more pollen is coming.

What to clean, in order

1. Roof and gutters first. Pollen and pine straw wash off the roof and into the gutters, then everything that comes off the roof runs down your siding. Cleaning top-down means you are not re-dirtying finished work.
2. House exterior next. Soft wash the siding once pollen breaks. It removes the pollen film and, more importantly, kills the mildew and algae that pollen and moisture feed.
3. Windows after the house. Washing siding sends dirty runoff across glass, so windows always go last.
4. Concrete and decks whenever. These are independent of the rest and can be done anytime the weather cooperates.

Why pollen is not just cosmetic

Pine pollen settling in gutters mixes with water into a dense paste that blocks downspouts. That backed-up water sits against your roofline and fascia. Every spring we pull gutters full of what looks like wet sawdust off homes where the owner had no idea anything was wrong.

If you do only one thing after pollen season, clear the gutters.
