Window care across Snohomish County
Snohomish County runs from Puget Sound to the Cascade crest, but most homes are in the western lowlands, where conditions change a lot from town to town. NOAA 1991–2020 normals range from about 33 inches of precipitation a year at Paine Field to about 51 in Monroe, and the Puget Sound Convergence Zone regularly soaks the southern cities.
Water varies just as much. Everett's Spada Lake water, which serves about 75% of county homes and businesses, is very soft (about 12.5 mg/L). But Stanwood's well water is very hard (about 188 ppm), and USGS found most sampled wells in western Snohomish County moderately hard, with iron and manganese above aesthetic limits in many. That's why we check what's causing the spots before choosing a cleaning method.

Local know-how
What's hard on windows in Snohomish County.
Soft city water, hard well water
From very soft Everett water to very hard wells, we identify what's on your glass before we clean it.
Conifer pollen everywhere
Tree canopy covers about 56% of the county on average (PSRC), so spring pollen coats glass and screens region-wide.
Rain varies, so schedules should too
From about 33 inches a year on the coast to 51 in the foothills, cleaning frequency should match where you live.

Good questions
Snohomish County window cleaning FAQ.
Don't see your question? Text us and a real person will answer.
Does Wonderboy serve unincorporated Snohomish County?
Yes. We serve all of Snohomish County, including unincorporated communities like Martha Lake, Silver Firs, Maltby, Clearview, Cathcart, and Machias.
Is Snohomish County water hard?
Most homes get very soft Everett water (about 12.5 mg/L). But groundwater is a different story: Stanwood's city wells are very hard, several districts blend in well water, and USGS found most sampled private wells moderately hard. If you have white or rusty spots on your windows, harder well water on sprinklers is the usual cause.
