The King of Kings Difference
Redefining the Standard in Exterior Cleaning
Professional methods, meticulous attention to detail, and real respect for your property — from the first walk-around to the final check.
Never the Wrong Pressure
Roofs, houses and pavers are always soft washed with low pressure. High pressure is saved for concrete and the surfaces built to take it.
Professional Window Cleaning
Detailed hand work on every pane, with frames and sills wiped down, not glass that has simply been sprayed off.
Care for Your Property
Landscaping, paint, trim and fixtures are protected while we work. We choose methods that clean thoroughly without putting the rest of your home at risk.
Attention to Detail
We are not racing to the next job. The finished work is checked before we leave, because it has to live up to the King of Kings name.

How Can We Best Serve You?
Residential
Window Cleaning
Streak-free interior and exterior window cleaning for Bellingham homes, from ground-floor panes to skylights and upper stories. Frames and sills included. Window cleaning starts at $4 per pane, per side.
Commercial
Window Cleaning
Storefronts, offices and multi-story glass, on a schedule or as a one-off. We work evenings and weekends where a business needs us out of the way of trading hours. Licensed and L&I insured.
House
Washing
Soft washed with low pressure: vinyl, brick, cedar, painted wood and fiber cement. We clear the algae and mildew at the root without forcing water behind the cladding. Starts at $399.
Pressure
Washing
Concrete driveways, sidewalks and patios, plus most composite decks. We pretreat the algae and growth sitting deep in the concrete, then finish with a surface cleaner for an even, streak-free result. Starts at $299.
Roof
Cleaning
Fir needles, leaves and branches cleared off the roof, out of the valleys and away from the gutter line, then carried off the property. Soft washing only where a surface needs it, never high pressure on shingles. Starts at $249.
Moss
Removal
Bulk moss is gently brushed off roofs, never pressure washed, and walkways and pavers are soft washed with the same moss treatment. Our soft wash kills the moss at the root, and we offer follow-up preventative maintenance to keep it from coming back. Starts at $699.
Gutter
Cleaning
Protect your home from water damage with our professional gutter cleaning services. We safely remove leaves, debris, and buildup to ensure proper water flow while keeping you off ladders. Using effective techniques, we leave your gutters clean and functioning perfectly, preventing costly issues like leaks or foundation damage.
Solar Panel
Cleaning
Maximize your solar panel efficiency with our expert cleaning services. Dirt, debris, and buildup can reduce energy output, but our safe and efficient methods using pure water restore performance and protect your investment. We ensure your panels are spotless and functioning at their peak, enhancing your energy savings.

What Builds Up on Bellingham Windows
Every part of town leaves something different on the glass. Here is what we see most.
Salt Haze
Homes near the bay in Fairhaven, Edgemoor and Squalicum get a salty film that leaves glass cloudy even after a rain.
Sprinkler Spots
Lower panes in Barkley and Cordata often carry mineral spots from lawn sprinklers that a hose and a cloth won’t lift.
Algae & Tree Pitch
Under the firs and cedars around Silver Beach and Lake Whatcom, glass picks up green algae, sticky pitch and needles.
Spider Webs & Pollen
Webs fill window corners and spring pollen coats the glass all over town, from Sunnyland to South Hill.
The Right Method for Every Surface
The wrong pressure on the wrong surface causes damage that costs more than the cleaning did. We look at every surface first, then clean it the way it needs to be cleaned.

Soft Washing
Soft washed with low pressure. A cleaning solution goes on gently, kills algae, mildew and moss at the root, and rinses away without forcing water under shingles or behind siding.
BEST FOR- Roofs, after bulk moss is gently brushed off
- House siding: vinyl, brick, cedar, painted wood and fiber cement
- Pavers and walkways

Pressure Washing
Algae and organic growth sink deep into the pores of concrete here. We pretreat with a growth killer, a degreaser or both, then run a surface cleaner for an even, streak-free finish.
BEST FOR- Concrete driveways, sidewalks and patios
- Most composite decks
Never pressure washed: roofs, houses or pavers. They are always soft washed with low pressure.
Moss and Roof Work Are Routine Here
The Pacific Northwest grows moss on north-facing slopes faster than most homeowners expect. Bulk moss is gently brushed off and the roof is soft washed, and gutter cleaning is free with moss removal.
