Yes. Sacramento tap water averages 198 mg/L TDS (total dissolved solids) — one of the highest in California. Calcium and silica deposits build up on glass over time. In the first 2 years, they’re removable. After 3+ years, silica can permanently etch into glass, requiring costly restoration at $20–$40 per window. Annual professional cleaning prevents permanent damage.

For Sacramento homes, purified water (deionized or reverse-osmosis filtered to under 10 TDS) combined with professional squeegee technique produces the best, longest-lasting results. Pure water leaves no mineral residue, so windows stay clean 2–3× longer than cleaning with Sacramento tap water. For existing hard water stains, Zillar applies a professional acid treatment to dissolve deposits before cleaning.

Most Sacramento homeowners benefit from 3–4 exterior cleanings per year due to heavy pollen in spring (March–May), wildfire smoke in summer (June–September), and irrigation overspray throughout the dry season. Interior cleaning is recommended 1–2 times per year. Homes near golf courses, parks, or agricultural areas may need more frequent service.

At Zillar, every window cleaning includes screen removal, cleaning, and reinstallation — plus frame and sill wipe-down and track vacuuming. These steps are often skipped by lower-cost providers. We include them in every service because that’s what actually leaves your windows looking professionally cleaned.
