Our Story
Why We Built a Window-Only Company in Portland
Portland’s climate is genuinely demanding on windows — light, repeated rain that redeposits grime instead of rinsing it away, heavy tree canopy that turns moss and algae into a structural risk, mineral spotting that can etch permanently into glass, and a real wildfire-ash season that’s only become relevant in the last several years. Most window cleaning in this city is still done by companies for whom glass is a side offering, not the core skill — gutter companies, general handymen, or large janitorial operations with window washing as one service among fifteen.
We saw the same pattern across the market: flat per-window pricing with no real inspection, moss and mineral spotting left untreated until it became a structural or permanent problem, and almost no company explaining why Portland windows behave the way they do. We built Portland Window Pros to do the one thing better than a company doing fifteen things — window-specific, climate-aware, and honest about what’s fixable versus what’s already permanent.
The Problem We Saw
Flat per-window pricing with no real inspection — moss, hard-water spotting, and access difficulty routinely missed until they became bigger, more expensive problems.
The Result We Built
A window-only team that inspects before quoting, treats moss and mineral issues at the source, and tells homeowners honestly when something’s already reached the point of no return.
The Portland Window Problem — What Makes This Market Different
Portland isn’t a typical window-cleaning market. Roughly 100+ days of measurable rainfall a year, concentrated October through May, means the standard “rain keeps things clean” assumption doesn’t hold here — and dense tree canopy across much of the city adds a moss and algae dimension that drier or less-shaded cities simply don’t deal with at the same scale.
Four distinct factors are active in Portland, each requiring a different approach:
🌧️ Rain Redeposit
Light, repeated rain lays down fresh grime rather than rinsing it away — the foundational layer behind most of Portland’s window-care problem. Learn more →
🌿 Moss & Algae
Dense tree canopy creates the shade and moisture moss needs to establish, potentially reaching and stressing window seals if untreated. Learn more →
💧 Hard Water/Mineral
Rain and sprinkler splashback both carry dissolved minerals that can etch permanently into glass if left untreated. Learn more →
🔥 Wildfire Ash
Alkaline wildfire ash, a newer and growing seasonal factor, can affect glass porosity if left sitting too long. Learn more →

Why Portland Window Cleaning Is Unlike Any Other Market
🌧️ The Rain Pattern
100+ days of measurable rainfall a year, mostly light and repeated rather than heavy — the mechanism that redeposits grime instead of rinsing it away, unlike drier or heavier-rain climates.
🌿 The Tree Canopy
Many Portland neighborhoods were built with heavy street-tree cover, some (like Laurelhurst) by deliberate design — creating the shade and moisture moss and algae need at a scale most cities don’t face.
🏚️ The Older Housing Stock
A meaningful share of inner Portland neighborhoods predate 1930, meaning original multi-pane and leaded glass windows are common and need different handling than modern panes.
🏡 The Real Estate Market
Portland’s median home value sits around $510,000–$540,000 — dull, spotty windows are a fast, visible “deferred maintenance” signal to buyers and inspectors.
🔥 The Wildfire Ash Factor
A newer, growing seasonal risk — alkaline ash can affect glass porosity if it sits too long, making late-summer cleaning genuinely protective, not just cosmetic.
🩺 The Health Angle
Mold at neglected sills is a recognized allergen — a real, if under-discussed, reason window care connects to indoor air quality.
