San Bernardino County · Inland Empire · 1,362 ft
Sonlight serves Redlands from the Smiley Heights and Sunset Drive districts through downtown, South Redlands and the streets climbing toward the San Bernardino front. Redlands has the finest citrus-era residential architecture in the Inland Empire and some of the hardest water underneath it.
Redlands Municipal Utilities draws Bunker Hill Basin wells and Mill Creek supply off the San Bernardino front, which is hard water carrying calcium from mountain alluvium. Combined with the deep landscaped grounds typical of the older districts and irrigation running through seven rainless months, mineral bonds onto ground-floor glass reliably here. What makes it more consequential than usual is the architecture: Redlands holds Victorian, Craftsman and citrus-era estate houses with original wood sash, art glass, leaded panels and divided lights that cannot be replaced in kind. Etching on that glass is permanent in a way that etching on a tract window is not.
The rest is heat and wind. Summer afternoons past a hundred and ten make west-facing glass unworkable after mid-morning, and the San Bernardino front immediately north funnels Santa Ana events with real force onto the mountain-facing elevations. Redlands also retains working citrus, which is part of its identity, and grove dust arrives whenever equipment moves through the blocks rather than when the weather changes. The foothill edges sit in genuine wildland interface.
Four variables decide what is on a window in Southern California and what it takes to get it off: which water you drink, how much ocean you get, where the wind comes from, and how long it goes without raining. Here is where Redlands sits on each.
Southern California does not run on the four seasons that window cleaning advice usually assumes. Redlands follows the Inland Empire calendar, which is the actual year in the order it happens and what each phase does to your glass.
What it does to glass
The year's rain arrives here and there is not much of it. The first storm mobilises seven months of accumulated warehouse film, field dust and mineral and runs it down the pane in streaks.
What we do about it
Clean in late October or November, before the first storm. In this region that appointment is worth more than any other on the calendar.
What it does to glass
Sustained afternoons past a hundred and ten with extreme UV. Whatever is on the glass in June is baked onto it by September, and the west elevation is always the worst.
What we do about it
West and south elevations first thing in the morning, shaded sides later in the day. This is not a preference, it is the difference between a clean window and a streaked one, and it is the single most common cause of complaints in this region.
What it does to glass
Seven months with no rinse while very hard irrigation water runs continuously, warehouse particulate accumulates, and agricultural ground throws dust on the farming calendar. This is when permanent damage is created.
What we do about it
Three visits a year for most Inland Empire properties, and we walk the irrigation before leaving to show you exactly which heads are hitting glass. That conversation is worth more than the cleaning.
What it does to glass
Cajon Pass and Santa Ana Canyon funneling produce the strongest offshore wind in Southern California, arriving from the desert with sand and grit. Tracks pack, weep holes block, screen mesh abrades, and the north and east elevations load hardest.
What we do about it
Tracks cleared dry before any water goes on, without exception, because the grit here is hard enough to scratch glass. Work booked into an active event gets rescheduled at no charge.

Redlands combines original art glass, leaded panels and century-old divided lights with hard basin water and deep landscaped grounds full of irrigation. Etching on that glass is permanent in a way it is not on a modern tract window, because you cannot simply order a replacement. Identifying which heads reach which panes matters more in this city than almost anywhere, and we spend time on it before we spend money on restoration.
Leaded came softens with age and a panel pressed while being cleaned bows and eventually fails at a solder joint. Original wood sash here has putty that failed decades ago with paint holding the glass since. Both get hand cleaning, no pressure, no pole systems and no cold water on sun-heated glass, and anything already bowing or failing gets photographed and reported.
Summer afternoons past a hundred and ten make west and south glass unworkable after mid-morning, because solution flashes off before it can be squeegeed. On a house with irreplaceable original glass that also means avoiding thermal shock from cold water on hot panes, which is a genuine risk on large old lights.
Pricing is per property: square footage, window count, stories and access. Here is a real Redlands example:
Example: Two-storey 3,200 sqft Smiley Heights period home, roughly 33 windows including leaded panels and original divided-light sash
Interior only
$470
Exterior only
$525
Both (most popular)
$875
Mineral restoration for irrigation etching is quoted separately. It is a different job than washing, and pretending otherwise is how customers end up paying twice. Get an exact price for your Redlands address in 30 seconds.

Interior and exterior glass, screens off the frame and hand-washed, and tracks cleared dry before any water touches the window.
The service this metro actually needs most. Most of Greater LA drinks 12 to 18 grain water, and irrigation overspray does more permanent damage to glass here than anything airborne.
Title 24 has put an array on nearly every home built since 2020, and seven rainless months mean nothing washes them. Measured California soiling is around 7 percent across a dry summer.
Near the coast salt pits the frame and hardens the spline years before the mesh looks worn. Inland, Santa Ana grit abrades it. Rescreening is routine here, not an upsell.
Low-pressure washing for stucco. Pressure drives water into a stucco wall assembly where it has nowhere to go, and the damage shows up months later.
Driveways, walks and hardscape, with a degreasing step where corridor oil is in the concrete. We keep pressure off stucco entirely.
Cement, stucco and gypsum fines cure onto new glass and are harder than it is. Dry-wiping them scratches permanently. This needs a dedicated flooded pass.
Only where your roof actually has gutters. Barrel tile here frequently carries partial runs, and low-slope roofs drain through scuppers instead. We check before quoting.
Yes, by hand and carefully. Leaded came softens with age, so a panel pressed while being cleaned bows and eventually fails at a solder joint, and these panels are not replaceable in kind. They get no pressure, no pole systems and no thermal shock from cold water on sun-heated glass. Anything already bowing or with a failed joint gets photographed and reported.
Yes. The city draws Bunker Hill Basin wells and Mill Creek supply off the San Bernardino front, and that water carries calcium from mountain alluvium. With deep landscaped grounds, extensive irrigation and no rain from May through November, mineral bonds onto ground-floor glass reliably. On a house with irreplaceable original glass, that makes sprinkler aim genuinely important.
Late October or November before the first storms, and March once Santa Ana season closes out. In summer, book a morning slot. Afternoons past a hundred and ten make glass unworkable, and on large original panes there is also a real thermal-shock risk from putting cold water on hot glass.
