Streak-Free Window Cleaning Services

Clean windows brighten every room, improve natural light, and give your Bellevue home a more polished appearance. Over time, rain, moisture, pollen, dust, and everyday outdoor buildup can leave glass looking cloudy and streaked, making regular window cleaning an important part of exterior home care.

In Bellevue and throughout King County, changing weather conditions can contribute to buildup on windows and frames throughout the year. Johnny Tsunami provides professional window cleaning to safely remove dirt, water spots, and accumulated grime, helping your windows stay clearer and your home look well-maintained.

Our Window Washing Process

Every job follows a process built for one outcome: spotless, streak-free glass, start to finish. Here’s how it works.
01

Window Assessment

We start by reading the glass — its type, age, and condition — so we choose the safest method for your specific windows.

02

Pure Water Cleaning System

Exteriors get our three-stage reverse osmosis pure water system. No chemicals, no residue, no streaks — just clear glass that dries flawlessly on its own.

03

Traditional Detailing for Interiors

Inside, we go by hand with gentle, eco-friendly solutions and careful detailing, treating every pane the way it deserves.

04

Final Inspection and Touch-Ups

Before we pack up, we walk the whole job and check every window — anything short of sparkling gets another pass.

Signs It's Time to Clean Your Commercial or Residential Windows

Most people don’t realize how much has built up on their glass until they see it clean again. If it’s been a while — or things are just looking dull — these are the tells.

Water Spots, Smudges & Streaks

Stubborn marks and mineral residue keep glass looking dirty no matter how often you wipe it down yourself.

Reduced Natural Light

A film of grime quietly filters your sunlight, leaving rooms dimmer and less welcoming than they should be.

Visible Dirt, Pollen & Seasonal Buildup

Dust, pollen, and everything the seasons blow your way settle into a haze you can see from across the room.

Hard-to-Reach Windows Showing Buildup

Upper stories, skylights, and awkward angles collect the most grime and are the least safe to tackle on your own.

What We Look For During Window Cleaning

Cleaning the glass puts us right at the window — so we keep an eye out for small problems that can shorten a window’s life if they go unnoticed.

Fog or Moisture Between Panes

Cloudiness or moisture between panes can indicate a failed window seal. We'll point it out so you know the window may need further evaluation or replacement.

Damaged or Missing Weather Stripping

That thin strip around the frame is what keeps drafts and rain outside. We check for gaps, cracks, and stretches that have gone missing altogether.

Mold or Mildew Around the Frame

Basement and bathroom windows collect moisture first. We look closely for early growth and moisture-related buildup so you can address the issue before it becomes more difficult to manage.
