When does pollen season start for window cleaning in North Carolina?

NC pollen season typically runs from late February through May, with peak intensity in March–April when pine and oak pollen blanket everything. This is when professional window cleaning makes the biggest visible difference. We recommend late April or early May for a post-pollen deep clean, once the yellow dust has settled.

How often should I pressure wash my driveway in NC?

Once a year is the baseline for most NC driveways. However, homes under heavy tree cover (common in Sanford and Lee County) often need it every 6–9 months due to faster algae growth in shaded, humid conditions. Schedule your pressure washing after pollen season (May–June) and again in early fall (October) for best results.

What's the best time of year to book Christmas light installation?

Book by September for the best availability. Installation begins in October and runs through mid-December. Takedown starts January. Our calendar fills up fast — especially for commercial properties that want lights up before their holiday displays are announced.

Can you clean gutters in winter?

Yes — winter gutter cleaning is actually critical. Clogged gutters combined with freezing temperatures create ice dams that can damage your roof. We clean gutters year-round, though we avoid scheduling on days with active ice or snow for safety reasons.

Why NC Homes Need a Different Cleaning Schedule

North Carolina sits in a climatic sweet spot that's beautiful to live in but brutal on building exteriors. We get four distinct seasons — but with a twist: long, intense pollen seasons (late February–May), extended humidity-driven algae growth (June–September), active hurricane seasons (August–October), and heavy leaf fall (October–November). A standard "wash once in spring" schedule that works in drier climates doesn't cut it here.

The key insight: in NC, cleaning is preventative, not cosmetic. A gutter cleaned before hurricane season prevents thousands in water damage. Soft washing applied in spring prevents months of siding algae. Windows cleaned post-pollen stay clear far longer than windows cleaned during peak yellow dust. The calendar below reflects 15+ years of Sanford and Lee County exterior maintenance experience.

Month-by-Month Calendar

January

30–50°F · Interior Window Cleaning

With outdoor temps low, January is ideal for interior window cleaning. Warm water-fed pole work is limited outdoors but possible on milder days.

February

33–56°F · Pre-Pollen Prep

February is your last chance to get windows spotless before NC pollen season hits. Early soft washing prevents heavy spring algae blooms.

March

42–67°F · Pollen Season Begins

NC's infamous yellow dust arrives. Exterior window cleaning during peak pollen is counterproductive — focus on interior work and surface prep instead.

April

49–75°F · Peak Pollen + Gutter Season

Pollen at maximum intensity. Gutters fill with pollen-laced debris. The humidity rises — algae starts growing visibly on siding and driveways.

May

57–83°F · Post-Pollen Deep Clean

Pollen subsides. This is the single best month for comprehensive exterior cleaning. Clean everything — you'll see the results all summer.

June

65–90°F · Summer Maintenance

Hot and humid. Algae and mildew grow aggressively on north-facing surfaces. Soft washing treatments last longer in this weather because they kill roots, not just surfaces.

July

69–93°F · Peak Algae Season

The humidity spikes and algae takes over. Driveways turn green. Windows haze over from humidity and road dust. This is the month soft washing earns its keep — it prevents regrowth longer than pressure washing alone.

August

68–91°F · Hurricane Prep Begins

Peak hurricane season approaches. Clear gutters and downspouts now to prevent water damage during heavy rains. Trim overhanging branches that could scrape windows in high winds.
