Seattle's Trusted Window & Home Cleaning Pros
Expert window cleaning and home maintenance for Northwest Washington homes.
Professional window cleaning across Greater Seattle
Windows in the Pacific Northwest take a beating. Marine air deposits a fine salt film. Douglas firs and cedars drop sap and pollen through spring and summer. Winter rain leaves mineral streaks the moment it hits dusty glass.
A quick spray with the garden hose won't touch any of it — and DIY squeegee work usually ends in streaks, missed corners, and a sore back. Northwest Pro Cleaning handles window washing the way it should be done: proper solutions, professional squeegees, extension poles for upper-story panes, and detail work on the frames and tracks most cleaners skip.
We serve homeowners across King, Snohomish, and Skagit County — from Ballard bungalows to Sammamish plateau homes to Mount Vernon farmhouses.
Every pane, track, and sill — done properly
A real window cleaning service isn't just the glass. Here's what we cover on every job:
- ✓ Exterior glass — hand-washed and squeegeed for a streak-free finish
- ✓ Interior glass — same treatment, with drop cloths and shoe covers indoors
- ✓ Window screens — removed, brushed, rinsed, and reinstalled
- ✓ Tracks & sills — vacuumed and wiped clean of pollen, dust, and debris
- ✓ Frames — wiped down of cobwebs, dust, and residue
- ✓ Skylights & specialty glass — French doors, storm windows on request
For high or hard-to-reach panes, we use pure-water fed-pole systems — no ladder resting on your siding, no soap residue drying in the sun.
