Window Cleaning

Pure-water washing that cleans the whole window, glass, tracks, sills and screens, and leaves nothing behind but light.

Tired of paying for streaks?

Streaks come from minerals in tap water, so we remove the minerals before we ever touch your glass. Our reverse-osmosis and deionization rig purifies the water to 100%, which means it dries spot-free without chemicals baked onto the pane. Then we clean the whole window housing: glass scrubbed, sliding tracks deep-cleaned so windows glide again, frames and sills wiped, screens dry-brushed. Most cleaners stop at the glass. We stop when the window works and looks like new.

  • Cleaners who squeegee the glass and leave the grimy tracks and sills untouched
  • Streaks that show up the first sunny afternoon after the crew leaves
  • Wobbling on a ladder over a second-story flower bed
  • Hard-water spots that never quite come off

What's included in window washing

  • Pure-water washing

    Purified water dries completely spot-free, which is how we guarantee streak-free glass instead of promising it.

  • Tracks, sills and frames

    Sliding tracks deep-cleaned so windows glide like new, frames and sills wiped down. The whole housing, never just the pane.

  • Screen care

    Screens removed, dry-brushed and reinstalled properly.

  • Hard-water treatment

    Mineral staining treated where it has etched into the glass.

  • High and hard-to-reach glass

    Water-fed poles reach second-story and awkward windows safely from the ground. Skylights and storm windows included.

  • Two-person insured crew

    Every job runs with two people on site, fully insured for ladder and exterior work.

The last window cleaning you'll need to shop for

One-time cleanings are welcome, and most homes look their best on a spring and fall rhythm. Recurring customers save 10% and keep their spot on the route. Pair windows with a gutter blowout or a house wash and one crew handles it in one visit.

We wash windows across southern Wisconsin: Janesville, Madison and its west-side suburbs, Lake Country from Oconomowoc to Delafield, Brookfield and Elm Grove, the Milwaukee North Shore, and the Lake Geneva area.

How it works

  1. 01

    Count and quote

    Priced per window, so the quote is simple and holds. Photos work fine if every window is visible.

  2. 02

    Clean the housing

    Glass scrubbed with purified water, tracks deep-cleaned, sills and frames wiped, screens dry-brushed.

  3. 03

    Walk the glass

    We check every pane in good light before we leave. If anything's not right, we fix it on the spot.

FAQ

Window Washing questions, answered

Yes. Purified RO/DI water dries without spots because there are no minerals left to dry. If you find a streak, we come back and fix it.
