Grand Strand pre-Memorial-Day seasonal opens accelerate sharply through May.
June through August is production window with substantial Lowcountry humidity squeeze. Charleston historic residential lighter (owners often elsewhere). Grand Strand peak-season hospitality turnover dominates. Upstate summer steady. Mid-summer rate drop in Lowcountry is real and unavoidable.
Late September through early November is cleanest production stretch statewide. Charleston winter-resident return triggers high-end residential booking surge late October through November. Lowcountry commercial Q4 contracts. Upstate fall mild and long.
December through February permits year-round exterior work in Lowcountry. Charleston second peak December as winter-resident return triggers residential surge. Upstate occasional freeze events but mostly continues. Statewide commercial interior work fills off-season.
Three to four week yellow film deposition on horizontal and east-facing vertical glass. Wet-only handling. Do not scrape. Heaviest pollen-deposition state in the country alongside Georgia and Alabama.
Summer algal-bloom deposition on lake-facing glass. Standard alkaline-soap with extended dwell handles it.
Columbia runs at 70 mg/L (CaCO₃) on City of Columbia Water lake or reservoir surface water — moderately hard, meaning municipal water leaves minor mineral residue on dark glass over extended dry-down. Hardness can vary block-to-block on mixed supplies; use our ZIP-code hard-water tool for a finer-grained reading.

Single-story homes in Columbia with accessible glazing can be cleaned by homeowners with basic squeegee technique.
