Professional Window Cleaning Services in Los Angeles
Dirty windows block up to 40% of natural light and cause permanent glass damage when left untreated. In a city where smog, hard water, and wildfire ash hit your glass year round, professional cleaning is not optional — it is maintenance. Salazar Cleaning Services provides interior, exterior, hard water stain removal, and complete glass care for homes and businesses across Los Angeles.
Why Los Angeles Windows Need Professional Cleaning
The standard industry recommendation for residential window cleaning is twice a year — once in spring, once in fall. In Los Angeles, that schedule falls short. The city's air quality, mineral-heavy water, and constant sun exposure create conditions that damage glass faster than almost anywhere else in the country. LA homeowners should plan for professional cleaning every 3–4 months to stay ahead of the buildup.

Smog and Airborne Particulate Buildup
Los Angeles currently does not meet the U.S. EPA's national air quality standards for both PM2.5 and ground-level ozone — the two pollutants that form the smog the city is known for.
The LA basin sits between mountain ranges that trap polluted air in what scientists call a marine inversion — warm inland air holds cooler, polluted ocean air close to the ground, creating a "pollution dome" over the city that is one of the strongest in the world. Soot, vehicle emissions, dust, and fine metals stay suspended near ground level instead of dispersing. With a population of roughly 4 million in the city and 10 million in the county, the volume of vehicular emissions and traffic-generated particulate matter is massive — and all of it settles on exterior surfaces, including your windows.
Santa Ana Winds and Wildfire Ash
Smog season runs from May through September, but the Santa Ana winds add another threat by carrying dust and wildfire ash across the region — sometimes for days at a stretch. After a wind event, exterior windows can go from clean to visibly coated in 24–48 hours.
According to the County of Los Angeles Public Health Department, 1 in 10 children in the county have been diagnosed with asthma — a direct indicator of how much particulate matter circulates in LA's air. Those same particles settle on your window glass, frames, tracks, and screens, then enter your home every time you open a window.
Hard Water Stains and Mineral Damage
Hard water contains dissolved calcium and magnesium that leave white, chalky deposits when water evaporates from glass. The U.S. Geological Survey classifies water with more than 180 mg/L of dissolved minerals as "very hard," and many areas across Southern California test at or above that threshold. In Los Angeles, the most common sources of hard water staining on windows are sprinkler overspray, garden hoses, rain splash from concrete walls, and condensation buildup.
USGS hardness scale
180 mg/L"very hard"
SoftModerateHardVery hard
Many areas across Southern California test at or above this threshold.
The damage progresses in stages if left untreated:
01
Stage 1 — Surface film (weeks to months).
Fresh deposits sit on the surface and respond to standard cleaning. The glass itself is undamaged.
02
Stage 2 — Bonded buildup (months to a year).
Older deposits bond to the silica in the glass and no longer respond to household cleaners. Professional products and techniques are needed.
03
Stage 3 — Permanent etching (beyond one year).
Minerals chemically react with the glass surface and create microscopic pits. This is physical damage, not a stain. Standard cleaning cannot restore it. Professional restoration may help in moderate cases, but severe etching often requires window replacement.
The sooner hard water stains are professionally cleaned, the lower the risk of permanent damage.
Energy Efficiency and Indoor Light Loss
Dirty windows reduce natural light transmission by 15–25% on average. Heavily soiled windows can block up to 40% of available sunlight from entering your home.
In a city with as much sunshine as Los Angeles, that has real consequences:
Light transmission100%−15–25%up to −40%
Higher electricity bills.
Less natural light means more artificial lighting during the day. Professional cleaning can reduce reliance on electric lighting by 30–50% during daylight hours.
Increased cooling costs.
Many LA homes have Low-E (low emissivity) coated glass designed to reflect infrared heat and keep interiors cool. Standard double-pane windows provide an insulation R-value of 2.1, compared to just 0.9 for a single pane — but that performance depends on the glass being clean. When grime, dust, or mineral deposits build up on Low-E surfaces, the coating cannot function properly. Your windows trap heat instead of reflecting it, and your AC system works harder to compensate.
Lost passive solar heating.
In cooler months, clean windows allow free solar heat to warm your interior. Dirty windows block this warmth, forcing your heating system to compensate.
Curb Appeal, Property Value, and Window Lifespan
Real estate professionals consistently emphasize window condition when staging homes for sale. Dirty or neglected windows raise immediate buyer concerns about how well the rest of the property has been maintained, while spotless glass makes a home look modern, well-cared-for, and inviting.
Beyond appearance, regular cleaning extends the physical lifespan of your windows. Environmental contaminants, mineral deposits, and oxidation from metal frames build layer upon layer over time. Left unchecked, these deposits permanently degrade the glass surface — turning a cleaning problem into a replacement expense. Routine professional cleaning prevents that cycle before it starts.

What we do
Our Window Cleaning Services
We provide residential and commercial window cleaning throughout Los Angeles and the surrounding areas. Every service is tailored to the property type, glass condition, and access requirements.
We clean interior and exterior windows, screens, tracks, sills, frames, sliding glass doors, skylights, French doors, and multi-pane detailing — ground floor through upper stories. Dust, pollen, mold spores, and allergens build up on glass, frames, and tracks over time, and in coastal LA's ocean humidity, neglected sills develop mold and mildew that enters your home every time a window opens. Industry guidelines recommend screen cleaning at least twice a year (spring and fall) to clear accumulated pollen, dust, and insect debris. Every job ends with a full walkthrough before we leave.
Commercial Window Cleaning
~55%of the overall window cleaning market is commercial
Commercial cleaning accounts for roughly 55% of the overall window cleaning market — because the condition of your glass directly affects how clients perceive your brand. We service storefronts, display glass, office buildings, restaurants, hospitals and medical facilities, hotels, retail chains, and multi-tenant commercial properties — interior and exterior. Recurring agreements are available weekly, bi-weekly, monthly, or quarterly, and we schedule around your business hours so there is no disruption to operations.

Hard Water Stain Removal and Glass Restoration
If your windows have visible mineral deposits, cloudy spots, or white haze that regular cleaning has not removed, our restoration service can help.
Mineral dissolverNon-abrasive padsDI water rinseCerium oxide polish
We use pH-balanced mineral dissolvers formulated for calcium and magnesium deposits, non-abrasive scrubbing pads that will not scratch the glass, and a final deionized water rinse that leaves zero residue. For more severe buildup, we use cerium oxide polishing to restore transparency without replacing the window.
Extra care is taken with Low-E coated, tinted, tempered, laminated, and filmed glass — all of which require specific products and techniques to clean safely.
Post-Construction Window Cleaning
$4–$5per pane, typical post-construction rate
New builds and renovations leave behind fine dust, concrete splatter, paint overspray, adhesive residue, and putty that household cleaners cannot handle. Post-construction cleaning typically runs $4–$5 per pane, with additional charges for windows covered in paint, putty, or heavy debris.
Available for new construction, remodels, additions, and any project where construction materials have settled on glass surfaces.
Every style, every pane
Window Types We Clean
Every window style has different access requirements and cleaning considerations. Our team handles all common types found across Los Angeles properties.
Residential Window Styles
Single-hung and double-hung, casement (crank-open), sliding, bay and bow, picture windows, awning, French windows and French doors, skylights and roof windows, transom windows, and floor-to-ceiling glass walls.
Commercial Glass
Storefront display glass, curtain wall systems, lobby and entrance glass, partition glass, and interior office glass.
Specialty Glass That Requires Extra Care
Not all glass can be cleaned the same way. Using the wrong products can void warranties, damage coatings, or scratch surfaces.
Low-E coated glass — Thin metallic coating that reflects infrared light. Abrasive pads and ammonia-based cleaners can strip this coating. We use only pH-neutral, non-abrasive solutions.
Tempered (safety) glass — Heat-treated for strength, commonly found in doors, bathrooms, and skylights. Requires careful cleaning to avoid micro-scratching that is more visible on tempered surfaces.
Tinted and filmed glass — Harsh chemicals and abrasive tools can discolor or peel the tint. We use manufacturer-safe products and soft application tools.
Stained and leaded glass — Found in older or historically designed LA homes. Requires extremely gentle methods to protect leading, solder joints, and delicate glass panels.
Two proven methods
How We Clean Your Windows
We use two primary cleaning methods depending on your property, window accessibility, and glass condition. Both deliver streak-free, spot-free results.
Traditional Squeegee Method
The professional standard for interior windows, detailed residential work, and glass that requires hands-on attention. Our technicians use professional-grade squeegees with replaceable blades, T-bar scrubbers, lint-free microfiber cloths, and eco-friendly cleaning solutions.
We use overlapping squeegee strokes and figure-eight scrubbing patterns to lift grime evenly. All work is done in shaded conditions whenever possible to prevent premature drying — a common cause of streaks in LA's direct sunlight.
Up to 4–5 stories
Water-Fed Pole System (Pure Water Cleaning)
For exterior windows on upper stories and hard-to-reach areas, we use a water-fed pole system with purified water.
Tap water passes through a multi-stage filtration process — sediment filtration, carbon filtration, reverse osmosis, and deionization — to produce water with zero total dissolved solids (0 TDS). This purified water is delivered through a telescopic carbon fiber pole fitted with a soft brush head that scrubs and rinses the glass from ground level.
Because the water contains no minerals, it dries completely spot-free without squeegeeing or towel drying. No chemical residue, no streaks, no water spots. The operator stays on the ground at all times, eliminating fall risk entirely. Poles reach windows up to 4–5 stories from ground level.

Eco Friendly, Glass Safe Solutions
All of our cleaning solutions are biodegradable, non-toxic, and free from ammonia and harsh chemicals. No chemical runoff touches your landscaping or property surfaces. For hard water stain removal, we use professional-grade mineral dissolvers at controlled dilutions — effective against calcium and magnesium deposits without harming the glass.
Maintenance schedule
How Often Should You Clean Your Windows in Los Angeles?
The right frequency depends on your property type and environmental exposure. Here is a guide based on industry standards adjusted for LA conditions:
minimumEvery 6 months
Residential homes (standard):
Every 6 months as a minimum. For homes near busy roads, construction, trees, or heavy pollen — every 3–4 months.
salt sprayEvery 3 months
Coastal LA (Santa Monica, Venice, Malibu, Marina del Rey, Pacific Palisades):
Every 3 months. Salt spray from the ocean accelerates mineral buildup on glass.
customer-facingEvery 2–4 weeks
Storefronts and restaurants:
Every 2–4 weeks. Customer-facing glass collects fingerprints, street dust, and grease that directly affect first impressions.
at minimumQuarterly
Office buildings:
Quarterly at minimum. Ground-floor lobbies and entrances should be cleaned monthly.
Monthly. Medical environments demand consistent attention to every surface.
entrances & lobbiesMonthly
Hotels and hospitality:
Monthly at entrances and lobbies. Full-building exterior cleaning at least quarterly.
safety & visibilityEvery 2–3 months
Industrial and warehouse facilities:
Every 2–3 months. Windows collect soot, dust, and chemical residues that reduce visibility and workplace safety.

Bundle & save
Bundle Window Cleaning with Solar Panel Care
An estimated 80% of two-income households in the U.S. are expected to use a professional cleaning service within the next two years — and the smartest way to get the most value from that investment is to bundle services together.
Your panels may be spotless on the roof while your windows below are blocking up to 40% of the sunlight entering your home. Clean panels and clean windows work together — one maximizes energy production above, the other maximizes natural light and passive solar heating inside.

C-61/D-63LIMITED SPECIALTY
Peace of mind
Licensed, Insured, and Cal/OSHA Compliant
California has the strictest window cleaning regulations in the country. We meet every one of them.
California Contractor's License
The California Contractors State License Board requires a C-61/D-63 Limited Specialty license for exterior window cleaning. This is a trade-specific credential that requires documented work experience, a written examination, and proof of insurance before it is issued.
Performing exterior window cleaning in California without this license is a criminal misdemeanor under California Business and Professions Code §7028. When you hire Salazar Cleaning Services, you hire a company that meets every state requirement to do this work legally.
Full Insurance Coverage
We carry general liability insurance and workers' compensation coverage for every crew member. California law requires every window cleaning business with employees to carry workers' comp — covering all team members, including part-time and seasonal staff.
If anything is accidentally damaged during our visit, our liability coverage handles it. If a crew member is injured on your property, our workers' comp policy covers them — not your homeowner's insurance.
Cal/OSHA Safety Standards
Our team follows Cal/OSHA safety protocols for all elevated work. California requires fall protection when workers are at heights of 6 feet or more — stricter than the federal OSHA standard. Our training, equipment, and procedures meet or exceed that requirement on every job.

How often should I have my windows professionally cleaned in Los Angeles?
Every 3–4 months is ideal for most LA homes due to smog, dust, and airborne particulate buildup. Homes near the coast should consider quarterly cleaning because of salt spray. The national standard of twice per year is usually not sufficient for the Los Angeles environment.
Do you clean both inside and outside?
Yes. We offer exterior-only, interior-only, and combined interior and exterior cleaning. Most residential customers choose the combined service for the best results.
Can you remove hard water stains?
In most cases, yes. Light to moderate mineral deposits respond to our professional removal process. If deposits have begun to etch into the glass surface, we use cerium oxide polishing to restore clarity. We assess the condition during your appointment and let you know what level of restoration is possible.
Will your products damage my window tint or Low-E coating?
No. We identify the glass type before starting and use only pH-neutral, non-abrasive, ammonia-free solutions safe for Low-E, tinted, filmed, and tempered glass.
Do you clean screens and tracks?
Yes. Our service includes screen removal, cleaning, and reinstallation, plus track, sill, and frame cleaning.
Are you licensed and insured?
Yes. We hold the California C-61/D-63 Limited Specialty contractor's license, general liability insurance, and workers' compensation coverage for every crew member.
Do you use eco-friendly products?
Yes. All solutions are biodegradable, non-toxic, and ammonia-free. Our water-fed pole system uses purified water with 0 TDS — no chemical runoff on your property.
Can I bundle window cleaning with solar panel cleaning?
Absolutely. We offer bundled Solar + Glass and Complete Exterior packages that combine panel cleaning, window cleaning, and gutter cleaning into one visit. Membership plans with six-month scheduling are also available.
How long does a typical appointment take?
Most residential jobs take 1–3 hours depending on window count, interior/exterior scope, and glass condition. We provide a time estimate when confirming your appointment.
