Spot-Free Window Cleaning in Placer County — Without Lifting a Finger
We brush, rinse with deionized pure water, and your glass air-dries crystal clear. No squeegee. No streaks. No effort on your part.
What we do
Exterior cleaning, done properly
Exterior Window Cleaning
Whole-exterior window cleaning with the DI pure-water system. Frames, sills, and glass — left to dry spot-free.
Screens & Tracks
Screens brushed and rinsed, tracks wiped clean. The details that make the whole job look finished.
Hard-Water Spot Removal
Mineral spots from sprinklers and hard water, treated and restored — common across Placer County homes.
Solar Panel Cleaning
Pure-water cleaning for rooftop solar — no harsh chemicals, no abrasive tools, nothing that voids warranties.
Gutter Cleaning
Gutters cleared of leaves and debris so water flows where it should, not over your siding.
Storefront & Commercial Glass
Scheduled storefront and commercial window cleaning for local businesses that want to look sharp.
The Thorn method
Why pure water changes everything
Most window cleaners drag a squeegee across your glass and hope for the best. We do it differently. Our deionized-water system filters ordinary tap water until virtually all dissolved minerals are gone. That mineral-free water goes up a pole through a soft nylon brush, loosens the dirt, rinses the glass — and then simply air-dries. With no minerals left in the water, there is nothing left behind to spot or streak.
- Brush. A soft nylon brush loosens dust, pollen, cobwebs, and grime — gentle on glass, screens, and frames.
- Rinse. Deionized pure water floods the surface, carrying everything away.
- Air-dry spot-free. No squeegee needed. The glass dries clear because the water itself is pure.

Questions, answered
Frequently asked questions
How much does window cleaning cost in Placer County?
Thorn Exterior Services offers flat-rate whole-exterior window cleaning so you know the price before we start. Call or text (916) 803-4778 for a free, no-pressure quote — final price depends on stories, pane count, and extras like screens or hard-water treatment.
What if there are streaks after you clean?
Then we come back and fix it free. Every exterior cleaning carries our 48-hour streak-free guarantee — if you're not happy with any part of it, tell us within 48 hours and we'll return to make it right at no charge. Call (916) 803-4778.
Do I need to be home during the service?
No. Since we clean exteriors with a water-fed pole system, we can service your home while you're away — as long as we have access to an outdoor spigot and the areas around your windows. We'll text you before and after.
What is deionized-water (pure-water) window cleaning?
Thorn Exterior Services cleans with deionized (DI) water — water filtered to remove dissolved minerals — applied with a nylon brush and left to dry spot-free. Because no minerals remain in the water, there are no spots or streaks as it dries, and no squeegee is needed.
Do you clean window screens and tracks too?
Yes. Thorn Exterior Services brushes and rinses window screens and wipes tracks as part of a full exterior service, using the same pure-water system. Call (916) 803-4778 to add screens and tracks to your free quote.
Which areas do you serve?
Thorn Exterior Services serves Rocklin, Roseville, Lincoln, Loomis, Granite Bay, Folsom, and El Dorado Hills — across Placer County, Sacramento County, and El Dorado County, California.
How often should I have my windows cleaned?
Most Placer County homes do well with exterior cleaning twice a year — spring pollen and fall dust are the big ones. Homes near busy roads, construction, or with sprinkler overspray on the glass benefit from quarterly visits.
