Pure-water cleaning

Using deionized or RO water for streak-free results. No detergent needed because pure water actively attracts minerals.

Squeegee technique

The wet-and-pull motion that removes water cleanly. Done in a fan pattern (interior) or a top-to-bottom straight pull (exterior).

Track + sill detail

Cleaning the bottom rail + frame area where dirt + pollen settle. Often skipped by $99 specials.

Screen washing

Removing screens + hand-washing them flat. Air-dries faster + cleaner than spraying them in place.

Streak-free guarantee

A return-visit promise if you spot a streak after the job. Industry-standard for premium service.

Water-fed pole (WFP)

A telescoping pole with deionized-water rinse + soft brush. Reaches 2-3 story windows from the ground without ladders.

Hard water spotting

Mineral deposits left by tap water + sprinklers. Requires acid wash or vinegar to remove.

Streak-free chemistry

Ammonia-based vs ammonia-free cleaners. Ammonia cuts grease but can damage tinted windows. Pros use a mild detergent or pure water.

Inside vs outside frequency

Exterior windows need cleaning 2-4× / year (Rochester pollen + lake-effect). Interior holds up at 1-2× / year unless cooking grease + pets.

Gutter cleaning add-on

Common service bundled with exterior windows. Roof debris in gutters causes ice dams + foundation water damage if neglected.
