Skylight Cleaning in San Clemente, CA

Why Skylights Get Dirty Faster Than Windows

A skylight lies flat or at a low angle, so rain doesn’t rinse it the way it rinses vertical glass. Instead, water pools, evaporates and leaves minerals behind. Near the ocean that residue includes salt, and on homes with trees nearby, sap and leaf stains. Over a season or two, a clear skylight can turn noticeably dim.

How We Clean Skylights Safely

• Roof access assessment — we check roof type and pitch first; clay and concrete tile common in San Clemente can crack if walked on carelessly
• Water-fed poles from the ground or a safe ladder position wherever possible, to keep foot traffic off the roof
• Deionized water rinse so the glass or acrylic dries without new spots
• Soft brushes only on acrylic and polycarbonate domes, which scratch easily
• Interior side cleaned with extension poles and drop cloths to protect floors and furniture

Glass, Acrylic and Tubular Skylights

Flat glass skylights, bubble-style acrylic domes and tubular daylighting devices each need a different approach. Acrylic is softer than glass and can haze if cleaned with the wrong products, so we avoid abrasive pads and ammonia-based cleaners. If a dome is already yellowed or crazed from UV exposure, cleaning won’t reverse that, and we’ll tell you before we start.

When Skylight Cleaning Isn’t Enough

Fogging or moisture between panes means a failed seal, and hard water marks that have sat for years can etch into glass. Read more in our guides on cloudy windows and whether hard water stains can be removed. For heavy mineral buildup, we may recommend hard water spot removal.

How Often to Clean Skylights Near the Coast

Most San Clemente homeowners do well cleaning skylights once or twice a year, usually alongside a full window clean. Homes under trees or directly exposed to ocean spray may benefit from more frequent visits.
