Window Cleaning Bellingham WA

Thanks, Randy, for the great job on our windows! It was our first time using a professional cleaner for our home, and the work was meticulous. He gave a reasonable bid, arrived right on time, and was diligent and thorough in his work. He even took the time to give us tips on how to clean ourselves in the interim.

Skylight Cleaning in Whatcom & Skagit County

A Local Crew Set Up For Roof-Level Glass

Skylights face straight up, which is the worst orientation for pollen, needle litter and marine grime, and they are the pane most often skipped. King of Kings cleans skylight glass inside and out wherever it can be reached safely, across Whatcom and Skagit County. Estimates are free and given before work starts.

King of Kings Window Cleaning is owner-operated and works Whatcom County, Skagit County and Oak Harbor. Skylights are cleaned on both faces where access allows, with the surround and the frame channel cleared so water can actually drain instead of sitting against the seal. We do not carry out roofing work, reseal units or replace glass, so anything we find gets reported to you plainly. Ask about roof cleaning if there is moss coming down onto them.

Skylight Cleaning FAQs

How often do skylights need cleaning?

Most want doing once a year, and roofs under conifer or heavy shade often need it more. Because a skylight faces upward it collects far faster than a wall window, so the gap between cleans is usually shorter than people assume.

Do you clean the inside as well as the outside?

Both, where the inside face can be reached safely from a pole or a ladder. Very high vaulted ceilings are the exception, and we will tell you what is reachable before booking rather than turning up and finding out.

Is it safe to walk on my roof to reach them?

We assess that first. Where the pitch, the roofing material or the weather makes it unsafe, we work from a pole or say no. Nobody should be putting weight on wet moss-covered shingle to clean a skylight, and we will not.

My skylight looks foggy inside the glass. Can you fix it?

No, and cleaning will not touch it. Fogging between the panes means the seal on the unit has failed, and that needs a glazier. We will point it out so you are not paying us to clean something that will still look cloudy.

Do you clear the moss around the frame?

Yes. Debris and moss packed in the channel around a skylight is what holds water against the seal, so clearing it out is part of the job rather than an extra. If the wider roof needs treating, that is roof cleaning and we will quote it separately.

Do you work on commercial skylights and atriums?

Often, yes. Shop, warehouse and office roof glazing is within what we do where access allows. Call (360) 303-6806, describe the building and the access, and we will give you a straight answer about what is workable.

Why Skylights Go Green Before Windows Do

A skylight faces straight up, which is the worst orientation for glass in this climate. Rain does not run off it the way it runs off a vertical window, so grit, needles and pollen settle and stay. Moss and algae take hold along the bottom edge and in the frame channel, and on a shaded roof they never fully dry out.

The change is gradual enough that most people do not notice it. A room that used to fill with daylight ends up dim and slightly green, and the assumption is that the weather has been poor. Cleaning the glass and clearing the debris out of the surround usually brings back more light than anyone expects.
