Reviews

What Washington homeowners say

4.9(127 verified reviews)
"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.

"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

Will the windows streak in the sun?

No. Pure de-ionized water dries with zero mineral content, so there's nothing left behind to streak — even in direct sunlight.

Do you clean screens and tracks?

Yes. Screens and tracks are included in our interior window service.

How often should windows be cleaned?

Twice a year is standard for PNW homes — once in spring after pollen, once in fall before the wet season.

Are you insured?

Fully insured for liability and worker's compensation. Certificate available on request.
