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.

LOCAL KNOW-HOW

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.

SOFT WASH VS. PRESSURE WASH

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.

LOW PRESSURE

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.
