What Washington homeowners say

"Booked a quote on a Tuesday, panels and windows done by Friday. They showed me before/after meter readings — solar output jumped 18%. No hard sell, just clean work."
Sarah K.
Bellevue, WA
"Three story craftsman with a moss problem on the gutters. Crew was on time, fully insured, used a ground-based pole — no scratched paint. Will book again next fall."
Mike T.
Seattle, WA
"Quoted in 40 minutes. The pure-water finish on the windows is genuinely streak-free, even on east-facing glass that gets full morning sun. Worth every dollar."
Jennifer L.
Redmond, WA
"Honest crew — told me my gutters didn't need a full clean, just a downspout flush. Saved me $180. That kind of straightforwardness earns repeat business."

FAQ

Common questions

How often should I clean my solar panels in Washington?

Every 6–12 months for most homes. Properties surrounded by evergreens, near farms, or with low-pitch roofs benefit from twice-yearly service.

Does rain clean my panels?

No. Rain can rinse light dust but leaves behind pollen, sap, droppings, and mineral spots. As water evaporates, contaminants concentrate — often making panels dirtier.

Is pressure washing safe for solar panels?

Never. High pressure can crack micro-seals, damage anti-reflective coatings, and void warranties. We exclusively use low-pressure pure water.

How long does it take?

Most residential systems (15–30 panels) take 60–90 minutes from arrival to walkthrough.
