Raleigh's 2026 Pollen Season Is Winding Down — Late-May Is Wash Window
The 2026 pine pollen peak in the Triangle is fading. Here's why late May is the right wash window — and what we're booking now.
If you live in Raleigh, you don’t need a calendar to know when pine pollen season is winding down. You see it on your porch railings, on your car, and especially on the north side of your house. The 2026 season tracked the long-term Triangle average closely — peak in late April, heavy continued shed through the first three weeks of May, and now finally tapering.
Why we tell clients to wait until late May
The most common mistake we see is homeowners washing during peak pollen — usually in late April or early May — and then watching the next week of pollen re-coat the freshly clean siding. Pollen shed in the Triangle continues for about three weeks past the visible peak. Washing during that window is wasted money.
The optimal Raleigh wash window is late May through mid-June, once the shed has clearly slowed. By that point, your wash buys you the longest clean stretch before the next major coating event (summer mildew growth on shaded surfaces) starts to show.

What pollen actually does to your siding
Pine pollen isn’t structurally damaging, but it has two annoying properties:
- It’s hygroscopic — it pulls moisture and creates a sticky surface coating that traps dirt and dust
- It builds up in horizontal seams and ledges where it can support light mildew growth if left alone for months
A late-spring soft wash strips off the season’s accumulation and resets the siding for summer. North-facing walls and shaded zones benefit most because they get less natural rain rinse.
Late-spring scheduling tip
The first two weeks of late-May fill up fast — most years we’re booking three weeks ahead by Memorial Day weekend. If you want to be in the optimal window, book by mid-May.
What we’re doing this week
Right now (week of May 18), we’re running two crews focused on residential post-pollen washes across Raleigh, Cary, Apex, and Wake Forest. Most jobs include the full house wash plus an optional gutter clearing — pine needles in gutters compound the season’s effect and contribute to fascia issues if left through summer.
