Seattle's Trusted Window & Home Cleaning Pros

Expert window cleaning and home maintenance for Northwest Washington homes.

Window Cleaning

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.

What's Included

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.

Common Questions

Window cleaning FAQs

How often should I have my windows cleaned?
For most Seattle-area homes, twice a year is the sweet spot — once in spring to clear off winter mineral streaks and pollen, and once in fall before the rainy season sets in. Homes surrounded by evergreens, near busy roads, or close to saltwater usually benefit from quarterly cleanings.
Do you clean interior and exterior windows?
Yes. Most homeowners book both together, since exterior alone still leaves interior film visible from inside. We can also do exterior-only if that's what you need.
What's included in your window washing service?
Glass (interior and exterior), screens, tracks, and sills. Frames get a wipe-down. We bring drop cloths for indoor work and shoe covers so nothing tracks through the house.
Do you clean windows in the rain?
Yes, and it's actually a myth that rain ruins a clean job. Clean windows only get dirty from what's on them — dust, pollen, minerals. Fresh rain on freshly cleaned glass runs right off.
How much does window cleaning cost in Seattle?
Pricing depends on window count, story height, screens, and access. Most single-family homes fall between $200 and $450 for a full interior and exterior cleaning. Send us your address for an exact quote.
Do I need to be home during the cleaning?
For exterior-only, no. For interior, we'll need access. We're happy to work with a gate code, lockbox, or scheduled meet.
Can you remove hard water stains?
Sometimes. Light mineral buildup comes off with our standard process. Deep etching from years of sprinkler overspray requires a separate restoration service — we'll tell you upfront whether it's worth attempting.
How long does a window cleaning take?
A typical single-story home takes 1–2 hours. Two-story homes with 25+ windows run 3–4 hours. We'll give you a time estimate along with your quote.
