Hard Water Stain Removal

If your windows still look cloudy after they are clean, this is why.

Close-up of a squeegee pulling water down glass covered in mineral spotting, the hard water staining common on Northern Nevada windows.

Northern Nevada has genuinely hard water. When sprinkler overspray, a leaking rain gutter, or run-off hits a window and dries in the sun, the water evaporates and the dissolved calcium and magnesium stay behind. Do that a few hundred times and you get the chalky white spotting you cannot wash off, because it is no longer sitting on the glass. It has bonded to it.

Left long enough, mineral deposits etch into the surface and the damage becomes permanent. The good news is that most of the glass we are called out to look at is not there yet. It looks ruined and it is not. We assess it honestly, treat what can be treated, and tell you plainly if a pane is past saving rather than selling you a service that will not work.

Worth Knowing

How glass gets to this point

Sprinkler overspray

By far the most common cause we see. A single misaimed head hitting a window twice a day will visibly etch that pane within a couple of seasons.

Run-off from a failing gutter

Water spilling over a clogged gutter runs down the wall and across the window below it, carrying minerals and roof grit with it every time it rains.

Sun bakes it in

High-desert sun evaporates water fast and drives the mineral bond harder. The same spotting in a cooler, shadier climate would come off far more easily.

Waiting makes it permanent

Early-stage deposits sit on the surface and come off. Late-stage deposits eat into it. This is one of the few cleaning problems that has a real deadline.

How It Goes

The Process

01

Look at it before quoting it

We need to see the glass. Severity varies wildly pane to pane and anyone quoting hard water removal sight unseen is guessing.

02

Test a small area

We treat an inconspicuous section first so you can see the realistic result on your actual glass before committing to the whole house.

03

Treat and neutralize

The deposits are broken down with compounds made for the job, worked in stages, then fully rinsed and neutralized so nothing is left on the surface.

04

Fix the cause

We point out the sprinkler head, the gutter, or the drainage that caused it. Restoring glass without fixing the source just resets the clock.

Our Promise

We will not take your money for glass we cannot improve. If the test patch shows the etching is permanent, we tell you, and you pay nothing for finding out.

What It Costs

Priced per window based on severity, because a lightly spotted pane and a decade-etched one are completely different jobs. This is separate from a standard window cleaning. Assessment and test patch are free.

Straight Answers

Hard Water Stains Questions

Can all hard water stains be removed?

No, and anyone who tells you otherwise is selling something. Surface deposits come off well. Once minerals have etched into the glass itself, the damage is physical and permanent. We test first so you know which one you are dealing with before you spend anything.

Will the treatment scratch or damage my windows?

Not when it is done correctly. We use compounds formulated for glass, we test first, and we take extra care with tempered and coated panes, which are less forgiving. This is exactly why it is worth having someone do it who has done it before.

How do I stop it coming back?

Fix what is putting water on the glass. Nine times out of ten it is a sprinkler head that needs turning a few degrees. We will show you the culprit while we are there.

Is this the same as regular window cleaning?

No. Regular cleaning removes what is sitting on the glass. Hard water restoration removes what has bonded to it. It is slower, it uses different products, and it is priced separately.

My shower doors have the same problem. Can you help?

Ask us when we are out. It is the same chemistry and the same technique, and it is often worth doing while we already have the equipment on site.
