Skylight cleaning in Los Altos Hills.

Skylights occupy an awkward middle position between window and roof work. The glass faces the most aggressive sun and weather exposure on the home, but the surrounds are often the most seal-sensitive — gaskets, flashing, and rubber surrounds that can be damaged by aggressive chemistry or technique. Cleaning them well requires understanding both the glass and the seal.

In Los Altos Hills, the conditions of the Mid-Peninsula hillside market sharpen the need. Eichler stock is skylight-heavy by design — atrium courtyards, clerestory bands, and overhead glazing throughout — and skylight cleaning is a standard recurring service here rather than an occasional add-on.

1. Roof-access assessment and verification of partner roofing-safety protocol.
2. Interior and exterior cleaning with chemistry that does not migrate into seal gaskets.
3. Inspection of seal condition during the visit — clouding, cracking, or compromise flagged for repair rather than cleaned around.
4. Final inspection with the homeowner of any skylight that needs follow-up attention.

• Annual or twice-yearly maintenance on Eichler, transitional, or modernist homes.
• After roof work or window replacement near a skylight.
• When interior glass begins to show condensation or clouding, which often indicates seal failure.
• Pre-event preparation where overhead glass will be visible to seated guests.
