The story

I moved across the country to do this right.

CARLTON, MN SAN RAMON, CA ABOUT 2,000 MILES

I'm Devan. I started cleaning in Minnesota in 2024, with gear I paid for by delivering food at night. Now I'm in San Ramon, building Optic the way I'd want it done at my own house.

The guy who quotes your windows is the guy who cleans them.

Questions

Straight answers.

How much does window cleaning cost in San Ramon?

Optic prices by the window. Outside only is $12 per window, inside and outside is $18.50 per window, and screens are $5 each, and tracks are $5 each. Every visit has a $125 minimum. Hard water spots and unusual glass are priced in your written quote. Use the estimator on the Get a price page, then send a photo and you get a written price by text before any work.

How do I get a price from Optic?

Text a photo of your windows to 218.451.6780, or fill in the Get a price form and add up to six photos. Devan looks at them and texts you a written price before any work is scheduled.

Will the price change when you show up?

No. What Devan quotes is what you pay. If something on site is different from the photos, he tells you before he starts and you decide. Nothing gets added at the door.

Do you offer window cleaning plans?

Yes, three. Twice a year takes 10 percent off every visit. Quarterly takes 20 percent off every visit and cleans your screens free. Monthly takes 25 percent off every visit, cleans screens free, and is built for outside glass that always looks fresh, with inside cleaning added at the same discount whenever you want it. Plan members get their price locked for 12 months, first pick of the calendar, and a free touch up if rain spots the outside glass within 7 days. No contract. Skip or cancel anytime by text.
