Hard Water Stain Removal
Cloudy glass? We can usually save it.
Hard Water Stain Removal done properly.
Sprinklers, lake spray and run-off from concrete leave mineral deposits that ordinary cleaning won't budge. We use specialty restoration compounds and polish to chemically and mechanically remove the etching.
Every job is quoted up front based on the size and access of your property — no per-hour creep, no surprise add-ons. Reach out below or call us for a same-day estimate.

Everything to know about hard water stain removal.
Hard water stains are the #1 reason homeowners think they need to replace 'cloudy' windows. In almost every case the glass itself is fine — what you're seeing is layers of mineral deposit (calcium, magnesium, silica) that have bonded to the surface from sprinkler over-spray, lake mist, or run-off from concrete and stucco above.
We start with a hidden test patch on each affected pane. If the compound lifts the stain cleanly, we proceed. If the glass is genuinely etched (rare, but possible on very old or chronically neglected windows) we tell you immediately — no point spending money on something that can't be fixed.
For successful restorations we follow up with an optional hydrophobic glass coating. The coating causes water to bead and run off instead of evaporating in place, which is what creates the build-up in the first place. Coatings last 1–2 years and pay for themselves by extending the time between restorations.

Frequently asked questions
Can you guarantee 100% removal?
If the glass is etched (physically pitted), no one can fully restore it. Most cases are mineral build-up which we remove fully.
How do I prevent it from coming back?
Adjust sprinklers away from glass, and consider a hydrophobic glass coating — we apply these as an add-on.
Will the restoration scratch my windows?
No — we test-patch first and only proceed when the surface tolerates the compound.
