Clean windows do more than look good
Based in Whittier, our team serves more than 120 communities across Southern California — from Malibu and Beverly Hills to Irvine, Newport Beach, Laguna Beach and San Clemente. Whether you need a one-time clean, recurring maintenance, storefront glass, post-construction cleaning or hard-water stain removal, DCS delivers detailed workmanship from start to finish.
Glass lets more natural light into your home or business, improves curb appeal and creates a better customer experience. It also protects the glass itself: mineral deposits, pollution and environmental grime etch into the surface over time, and once that damage sets in, cleaning can only do so much. Regular professional cleaning is genuinely cheaper than replacing panes.
We're licensed, insured and family-operated, and we use pure-water systems with eco-friendly detergents on every job.

Window cleaning FAQs
How often should windows be cleaned in Los Angeles?
Most residential properties benefit from professional window cleaning every 3 to 6 months. Commercial properties and storefronts often need monthly or bi-weekly service depending on foot traffic and environmental conditions. Properties near salt water usually go monthly.
How long does a typical window cleaning take?
A standard exterior clean takes around 2–3 hours for the whole outside. Inside-and-out runs about 4–5 hours, with a full deep clean adding roughly another 1–2 hours.
How much does window cleaning cost?
Residential jobs start at $100. The final price depends on property size, the number of windows, accessibility, and whether it's residential or commercial. Every estimate is free, with transparent upfront pricing and no deposit.
Can hard water stains be removed from windows?
In many cases, yes. Professional hard-water stain removal can significantly improve the appearance of affected glass and help prevent further damage. Where mineral deposit has etched deeply into the pane, we'll tell you honestly how much improvement to expect.
Do you clean multi-storey windows?
Yes. We provide professional multi-storey window cleaning for both residential and commercial properties, using proper access equipment and trained, insured technicians.
Can you remove construction dust from windows?
Yes. We provide post-construction window cleaning to restore glass after renovation or building work — including dust film, paint flecks and adhesive residue.
Why hire a professional instead of doing it myself?
Professional cleaning protects the glass, improves appearance, increases natural light and saves you a day on a ladder. Purified-water systems leave no mineral residue behind — which is the part that's genuinely difficult to replicate with household products and a cloth.
