Austin Water delivers water to Austin from surface (lake/reservoir) at 220 mg/L (CaCO₃). That is very hard for a US municipal supply. On Austin glass that residency means visible spotting on dark glazing within a single dry-down cycle and accelerated lower-sash mineral residue over the working year. The local operating practice is a citric pre-treatment followed by a citric finish-rinse on long-residence glass, and a deionized rinse on heritage and high-value stock where chemistry matters most.

Cedar pollen wave December-February is the operating reality — every surface coats yellow-green and respiratory PPE is standard for the crew.
Tech-corridor commercial work clusters around quarterly campus refresh cycles for the major employers; institutional volume is meaningful.
The seasonal rhythm in Austin runs on the broader Texas pattern — water and weather behave at the state level even when the housing stock varies by city.
March through May is the residential peak. The post-cedar-fever and post-oak-pollen passes drive the call volume; sprinkler overspray begins building in late spring.
June through August is the heat-load season. Work shifts to early morning (sunrise to 10am) and late evening (after 7pm) to avoid the flash-evaporation problem. Many cleaners decline new residential bookings July-August.
September through November is the second peak. Heat breaks in September; pre-holiday work begins in October.
December through February is steady commercial and selective residential. Hard freezes shut down residential work for two to four days at a time but the market does not close the way it does in the Midwest.
The central Texas mountain juniper releases huge volumes of cedar pollen from December through February — locally called cedar fever season. Pollen settles on glass in visible yellow clouds on heavy-release days. Sticks tenaciously and needs a surfactant pass.
Live oak and post oak release pollen from late February through early April. Yellow-green pollen layers everywhere in Austin, San Antonio, and the eastern hill country. Heavy enough to require a pre-rinse on most spring jobs.
Austin runs at 220 mg/L (CaCO₃) on Austin Water lake or reservoir surface water — very hard, meaning municipal water consistently leaves visible mineral spots and benefits from a citric finish-rinse on long-residence glass. Hardness can vary block-to-block on mixed supplies; use our ZIP-code hard-water tool for a finer-grained reading.
