GLASS IN
SAN JOSE.

San Jose glass fights three things at once: a six-month dry season, hard municipal water, and sprinklers. From May through October almost nothing rinses your windows — dust off the valley floor and pollen settle into a gray film that the first fall rain smears rather than cleans, because rain drops dry on glass and leave their own spots. Meanwhile every sprinkler cycle that clips a window bakes calcium and magnesium onto the pane in the afternoon sun. Wipe that mix around with a rag and dish soap and you get the classic result — streaks that only show up once the light hits them.

> The deionized water difference

We clean windows with the same purity rig we run for solar panel cleaning: a water-fed pole supplied with deionized water. Tap water carries dissolved minerals measured as total dissolved solids — when a drop evaporates, those minerals stay behind as the white spot you know from shower doors. Deionized water measures near zero, so the final rinse air-dries with nothing left on the glass. No squeegee passes to streak, no detergent film left behind to grab the next layer of dust.

> No ladders against your house

The pole reaches second-story glass from the ground. That means no ladder rails pressed into your stucco or siding, no ladder feet sinking into flower beds, and no one climbing past your bedroom window. The soft brush scrubs frame and glass first, then a pure-water rinse flushes the dirt off to dry spot-free.

> The whole window, not just the pane

Screens come off and get brushed and rinsed. Tracks are cleaned of the grit that makes sliders grind. Sills and frames are wiped down. Hard-water stain treatment is available as an add-on for glass with mineral buildup, and interior sides are cleaned by hand on request. Most customers pair window washing with a house wash — clean glass on dirty siding is a strange look.

WINDOW WASH
PROCESS.

01

Walkthrough & Count

Every pane counted and checked before water touches anything. Hard-water staining, oxidized screens, cracked glass, and painted-shut frames get flagged and discussed up front — no surprises at either end of the job.

02

Screens Off

Screens removed, laid out, brushed with a soft screen brush, and rinsed. They dry while the glass is being washed, so nothing damp goes back into the frame. Torn or oxidized mesh gets pointed out, not ignored.

03

Frame & Glass Scrub

The water-fed pole brush scrubs the frame first, then the glass — top down, so loosened dirt never washes over a clean pane. Deionized water flows through the brush the entire time, carrying debris off the surface.

04

Pure-Water Rinse

Brush lifts off the glass and a final stream of deionized water flushes the pane. Because the water carries no dissolved minerals, it air-dries spot-free — no squeegee, no towel marks, no streaks in afternoon light.

05

Tracks & Sills

Tracks brushed out and wiped so sliders and double-hungs stop grinding on grit. Sills and bottom frames wiped down. Weep holes checked so winter rain drains out of the track instead of pooling.

06

Dry Check & Rehang

Each window checked after it dries — spots only reveal themselves on dry glass. Any pane that needs a second pass gets one. Dry screens rehung, and stubborn mineral stains noted for add-on treatment if you want it.

San Jose windows washed spot-free — deionized water, screens and tracks included. Free estimates.

WINDOW WASHING
QUESTIONS

Straight answers for San Jose homeowners. Don't see yours? Call or text (408) 598-1857.

Why does deionized water dry without spots or streaks?

Tap water carries dissolved minerals — mostly calcium and magnesium. When a drop dries on glass, the water evaporates and the minerals stay behind as a white spot. Deionized water has had those minerals stripped out, so it dries with nothing left behind. That is why we can rinse a window and let it air-dry spot-free — no squeegee passes, no detergent film, no streaks when afternoon sun hits the glass.

Do you use a squeegee or a water-fed pole?

A water-fed pole for exterior glass. The pole feeds deionized water to a soft brush that scrubs the frame and glass, then a final pure-water rinse flushes everything off to air-dry spot-free. It is the same purity rig we run for solar panel cleaning, and it reaches second-story windows from the ground — no ladders leaning against your stucco or siding. Interior glass, when requested, is cleaned by hand with squeegee and towels.

Are screens, tracks, and sills included?

Yes. Screens come off and get brushed and rinsed before going back on. Tracks are brushed out and wiped so sliders and double-hungs move without grinding on grit, and sills and frames are wiped down. A window wash that only touches the glass is half a job.

Can you remove hard-water stains from the glass?

Usually — it depends on how long the minerals have sat. Fresh spotting, typically from sprinkler overspray, comes off with a dedicated hard-water treatment we offer as an add-on. Long-term staining that has etched into the glass may not polish out completely, and we tell you what to expect at each window before starting. Redirecting the sprinkler head is the cheapest fix of all.

Do you clean interior glass too?

By request. The standard service covers exterior glass, screens, tracks, and sills. If you want the interior sides done, mention it when booking — interior glass is cleaned by hand with drop cloths down and clean towels, not the water-fed pole.

How often should windows be washed in San Jose?

Twice a year keeps most San Jose homes clear. The dry season runs May through October, and the dust and pollen film that builds over those months does not rinse off with the first fall rain — rain drops actually dry into fresh spots. Many customers pair window washing with an annual house wash so the glass, screens, and siding are all done in one visit.

Are you licensed and insured?

Yes. Bull Run Exterior Wash LLC is fully licensed and carries general liability insurance on every job — in San Jose and across the South Bay, San Mateo County and lower Alameda County.
