Round Rock's window problem starts underground. The city straddles the Edwards Aquifer's karst limestone, and its supply blends aquifer well water with surface water from Lake Georgetown depending on zone and season. That blend runs genuinely hard — noticeably harder than Austin's Highland Lakes water ten miles south — and every drop a sprinkler throws against a pane in July leaves its minerals behind on the glass. Two identical houses on two sides of the city can spot at visibly different rates purely because of which water serves them.
Above ground, Round Rock lives on the same Central Texas calendar as the rest of the metro, with the volume turned up by growth. Cedar pollen arrives from the juniper breaks west of town every December through February. The live oaks along Brushy Creek and in the older neighborhoods drop their leaves and string their catkins in March. May storms splash pale caliche film onto brick skirts and lower panes. And through the summer bake, subdivision irrigation runs daily against some of the hardest municipal water in the metro.
Round Rock's housing stock is younger than Austin's, and that changes the work. Most of the city is production-built two-stories from the 1990s onward: tall entry glass over the front door, a two-story great-room wall at the back, builder-grade screens on every opening, and vinyl or aluminum tracks that pack with pollen and construction dust. We clean interior and exterior glass, hand-wash screens off the frame, detail tracks dry before wet work, restore mineral-spotted glass, clean gutters and solar arrays, and handle post-construction cleans in the neighborhoods still building out.
Every job is priced from public records before we arrive, and every clean carries our 24-hour guarantee: if something looks wrong after we leave, we come back at no charge.
Four variables determine how fast windows get dirty in a Central Texas town and what it takes to get them clean again. Here is where Round Rock sits on each.
Central Texas does not run on the four seasons window-cleaning advice usually assumes — the dirtiest season here is winter. Here is the actual year, in the order it happens, and what each phase does to your glass.
What it does to glass
Juniper pollen rides every dry north wind out of the Hill Country and films glass and screens across the city — the west-side neighborhoods nearest the breaks catch it first.
What we do about it
Off-frame screen washing and dry track detail before any water; a mid-winter clean here is the contrarian move that works.
What it does to glass
Brushy Creek's live oaks shed a year of leaves in weeks and follow with catkin pollen; under-canopy honeydew glues it to panes and sills.
What we do about it
Gutter clearing on the spring schedule the trees actually keep, plus a proper wet pass on the honeydew film — it smears if attacked dry.
What it does to glass
May supercells splash caliche-pale soil onto brick skirts and the bottom two feet of ground-floor glass; hail is an occasional real risk.
What we do about it
Lower-pane splash detail standard on storm-season cleans, and a gutter check anywhere the March drop went un-cleared.
What it does to glass
Months of heat with little rain while subdivision irrigation runs daily on hard blended water — mineral spotting builds fastest here of any season, worst on west-facing glass.
What we do about it
Morning cleans, sprinkler-head flags, and honest triage: baked-in scale gets restoration, not a futile re-wash.
What it does to glass
Rain returns and low autumn light rakes across the summer's accumulated film, making it suddenly visible indoors.
What we do about it
The full reset: glass, screens, tracks, gutters — done together before cedar season restarts the cycle in December.
Round Rock's Edwards Aquifer component is limestone groundwater, and it shows on glass. Sprinkler overspray that would take two summers to matter in Austin can etch visible spotting here in one. Once it has layered, it is scale: restoration work, not washing. We also tell you which sprinkler head is doing it.
The signature Round Rock window is the tall arch over the front door, twenty-plus feet up over a tile or concrete landing. It is the pane homeowners cannot reach and the one that shows every streak in afternoon sun. We carry the right ladders and water-fed poles for exactly this glass, inside and out.
Production homes from the 1990s and 2000s carry their original fiberglass screens, and Central Texas sun makes mesh brittle. Cedar pollen embeds in it every winter. We hand-wash screens off the frame, and when mesh has gone past washing we say so plainly — re-screening is routine here, not an upsell.
Pricing is per property: square footage, window count, stories, and access. We look up your home in public records and give you an exact, bookable price for your address. Mineral restoration for baked-on sprinkler scale is quoted separately — it is a different job than washing, and pretending otherwise is how customers end up paying twice.

The historic blocks around the namesake round rock in Brushy Creek — older sash, storm windows, and careful hand work.
Established trees, real canopy, and the March oak drop; gutters and honeydew film are the standing spring orders.
Golf-course production homes with two-story back walls of glass; sprinkler overspray on hard water is the recurring call.
1990s two-stories under maturing canopy — entry glass two ladders tall and screens that have baked twenty summers.
Compact lots where the neighbor's sprinkler reaches your window; we flag the head, not just the spot.
Newer stock on the east side, blackland dust and post-construction film as the neighborhood finishes building out.
The newest, fastest-growing corridor; builder screens, construction fines, and first-clean work.
West-side homes closer to the juniper breaks — cedar season lands here first and hardest.

Interior and exterior glass, screens hand-washed off the frame, and tracks cleared dry before any water — the only safe order in cedar season.
The limestone-country specialty: sprinkler overspray baked into scale by the summer sun, restored rather than re-washed.
On the spring schedule the live oaks actually keep — they shed in March, not October, and the May storms test every gutter they load.
Cedar pollen embeds in mesh every winter and Texas sun makes it brittle. Re-screening is routine here, not an upsell.
Central Texas summers can run months without rain while dust accumulates continuously — a dirty array underproduces exactly when output pays most.
Driveways, walks, and hardscape — including the storm-splash band that blackland clay and caliche leave on brick and stone.
One of the fastest-building metros in America: stucco, mortar, and gypsum fines cure onto glass and need a dedicated pass, never a dry wipe.
Low-pressure washing for stucco, stone, and siding — pressure belongs on flatwork, not on your walls.
Water. Round Rock's supply carries an Edwards Aquifer groundwater component that runs harder than Austin's lake water, so the same sprinkler overspray leaves more mineral behind per drop. The fix is the same everywhere — restoration for the existing scale, then keeping irrigation off the glass — but the clock runs faster here.
Yes. The two-story entry arch is the most-requested single pane in Round Rock, and we clean it inside and out with the proper ladders and water-fed poles rather than leaning something against your stone facade.
Late March or April, after the live oaks finish their spring drop — the opposite of the national fall-cleaning advice, because live oaks shed in spring. A second check after the first big May storm is cheap insurance in the canopy neighborhoods.
Yes, and new-build glass gets a dedicated post-construction first clean: stucco, mortar, and gypsum fines cure onto panes and grind into scratches if dry-wiped. If your street is still building out, that film returns and we plan for it.
