The seasonal rhythm in Yonkers runs on the broader New York pattern — water and weather behave at the state level even when the housing stock varies by city.
April through early June is the residential peak. The post-winter salt-and-grime call drives volume; pollen and cottonwood work picks up in May.
June through August is steady residential and commercial. Humidity is the working consideration — early-morning starts help on east-facing exposures. The trade does not shut down for heat the way Texas does.
September through November is the second peak. Pre-holiday cleaning drives October and November. The pre-Thanksgiving rush is real in NYC.
December through March is largely commercial. Residential exterior work is paused in the snow belt and reduced in NYC. Interior work continues; the better operators use winter for back-shop and equipment work.
Heavy road salting from December through March produces an aerosolized salt mist that bonds to ground-floor glass and corrodes aluminum and steel sash hardware over time. The salt film cleans off but the underlying frame damage is cumulative. Worst in NYC, Long Island, and the snow belt.
Pre-WWII NYC and inner-Westchester building stock still sheds a fine particulate that combines with airborne grime to produce the characteristic gray film on old brownstone and tenement windows. The film is not modern pollution alone — masonry chemistry and a century of coal-era residue are in the substrate.
The pre-1945 wood-sash housing stock in NYC, Westchester, and the older upstate cities is reaching the end of its original glazing putty service life. The putty crumbles around the perimeter of the pane and produces a chalky residue on the lower edge of the glass that cleaning does not solve. Documentation and a glazier referral are the right move.
