Pure water window cleaning uses purified water with the minerals stripped out, fed through a soft brush on the end of a 30 to 40 foot pole. It works so well on Cedar Park windows because our tap water is hard, and hard water is the reason DIY-cleaned glass dries spotty. Pure water has no minerals to leave behind, so the windows dry on their own without streaks.
We have been cleaning windows in Cedar Park since 2007. The question we get most often is, “I rinsed my windows with the hose, and they still look terrible. Why is that? “The answer almost always comes back to the water.
What Pure Water Window Cleaning Actually Is
Pure water window cleaning is a method that uses water filtered down to nearly zero dissolved minerals, delivered through a long carbon-fiber pole to a soft brush head at the top. The brush scrubs the glass while the pure water rinses everything off, and the window dries on its own.
There is no squeegee on the outside pass when we use this method. There is no soap. There is no ladder leaning against your siding. Our technician stays on the ground and works the pole up to whatever height the window sits at.
We use this method for almost every exterior window we clean in Cedar Park. For interior glass, we still use a traditional squeegee and a mild soap solution, since the inside of the house has fingerprints, splatter, and detail work that a pole cannot match.
Why Tap Water Leaves Spots on Cedar Park Glass
Central Texas water is hard. According to Austin Water’s quality reports, our municipal supply carries hardness around 184 ppm, with calcium around 40 mg/L and magnesium around 20 mg/L. Some local readings push higher.
That is the entire reason your hose leaves spots. When tap water dries on glass, the calcium and magnesium it carries stay behind as a chalky white film. Left long enough, those minerals etch into the glass and become permanent.
If your sprinklers hit the first-floor windows on a daily cycle, you are seeing the same chemistry over and over. We see it constantly in newer Cedar Park subdivisions like Buttercup Creek, Twin Creeks, Anderson Mill, Brushy Creek, and Ranch at Brushy Creek. The sprinkler heads were not aimed at the house, but the overspray landed on the glass anyway.
Pure water flips that problem on its head. The purification process pulls the minerals out before the water ever hits the window, so when it dries, there is nothing left behind.
How Our Pure Water System Works
The water goes through a multi-stage purification process before it reaches your house. A sediment filter pulls out dirt and rust particles first. An activated carbon stage removes chlorine. A reverse osmosis membrane forces the water through a barrier that catches the dissolved solids. A deionization resin polishes off whatever ions are left.
Tap water typically reads somewhere between 200 and 400 ppm of total dissolved solids. By the time the water leaves our purification system, it reads close to zero. That zero is the entire trick.
From the purification tank, the water travels through a hose up a carbon-fiber pole that reaches around 30 to 40 feet. That covers virtually every two-story home in Cedar Park, including the tall foyer transoms and back-of-house picture windows common in newer builds.
Here is what the job actually looks like when our crew shows up:
- We do a quick walk-around. We check for power lines, mark fragile plants, and rinse landscaping with regular water first.
- We start the purification system in the truck and feed pure water through the pole.
- The brush at the top of the pole agitates the dirt while the pure water rinses the glass, frame, and screen at the same time.
- We rinse top to bottom on each window and move to the next.
- The glass air-dries with no spots, no streaks, and no wiping.
Our technicians go through a 72-point training process before they ever work a Cedar Park home solo, and we hold membership with the International Window Cleaning Association, which writes the safety standard for our trade.
Pure Water vs. Squeegee: Where Each One Wins
Both methods have a place. We use both, and which one we pick on a given window depends on what the window is and where it sits.
See where each method fits best for Cedar Park windows.
| Scenario | Pure Water Pole | Traditional Squeegee |
|---|---|---|
| Two-story exterior glass | Best fit, we stay on the ground | Slower, requires a ladder for every pane |
| Frames, sills, and screens | Cleaned in the same pass as the glass | Has to be wiped or rinsed separately |
| Hard-water spot prevention | No minerals to leave behind | Tap water spots unless squeegeed before drying |
| Interior glass and fingerprints | Not the right tool | Best fit, what we use inside |
| Sprinkler-overspray mineral film | Strips it cleanly without redepositing | Often smears the film around |
| Around plants, pets, and kids | No chemicals, water only | Soaps and rinses can drip into landscaping |
The honest take from us: for outside windows in Cedar Park, the pure water pole wins on every count that matters. For inside glass, the squeegee still wins. That is why every full-service residential job we run uses both tools, just not on the same pane.
What This Means for a Cedar Park Home
Cedar Park has a specific kind of housing stock and a specific weather pattern, and pure water happens to be a great fit for both.
Most newer subdivisions here run two-story floor plans with tall front-door transoms, tall foyer windows, and big back-of-house glass facing greenbelts. The pole reaches them all from the ground. Nobody on a ladder, nobody on the roof, nobody leaning across a flowerbed.
Cedar fever season runs from December through February and drops a heavy layer of mountain cedar pollen on every west-facing window. Spring oak pollen does the same thing in a different color. A pure water pass with the brush head clears the pollen film off the glass and the screen in one motion instead of two trips with a hose.
Limestone dust from new construction sites in growing Cedar Park neighborhoods collects in window tracks. The brush head agitates it loose, and the rinse carries it out. Tracks and sills do still get extra attention as an add-on when the homeowner wants them detailed.
The median home value in Cedar Park sits around $513,600 as of 2024, with most subdivisions under HOA expectations for curb appeal. Clean glass, clean frames, and clean screens make the entire front facade read as maintained from the street.
When Pure Water Is Not the Right Call
We will tell you straight away when the method does not fit. There are a few situations where we either pull a different tool or pass on the work entirely.
Storm windows are hand-cleaned separately. They run $85 each. They are rare in Cedar Park, but we mention it so there are no surprises.
We will not run the water-fed pole anywhere it could come within 10 feet of overhead power lines. Pure water is conductive enough, and the pole is long enough that the risk is real. If your home has lines that are close to a window, we work that window with a different method or pass on it and tell you why.
Heavy oxidation, paint speckles, or post-construction debris get pre-treated before the pure water passes. We do not blast it off with chemicals, but the technician spot-treats and scrapes before running the pole.
What It Costs and What You Get
We publish per-window pricing because we believe the homeowner should know what to expect before they pick up the phone.
| Service Tier | Starting Price | What is Included |

| Interior + exterior | $16.30 per pane | Squeegee detail inside, pure water on exterior |
| Storm windows (each) | $85 | Hand-cleaning, separate process |
| Tracks and sills | Add-on, quoted on site | Detailed track and sill cleaning |
A typical Cedar Park residential job runs about two hours. Estimates are free over the phone for homes 3,500 square feet and under. Larger homes get an in-person estimate when we cannot pull enough detail from photos.
Two backstops sit behind every job. If it rains within seven days of the cleaning and the rain dirties the windows, we come back at no charge under our 7-day rain guarantee. And our 100% satisfaction guarantee means if you are not happy with the result, we are back out making it right.
Frequently Asked Questions
How often should we have our windows cleaned in Cedar Park?
Twice a year hits the sweet spot for most homes here. Schedule one cleaning after cedar pollen season tapers off in late February or March, and the other in October or November, before holiday photos and guests. Homes near active construction, near busy roads, or with kids and pets often run quarterly. Read more about the best window cleaning frequency for your property in Cedar Park.
Will pure water remove existing hard-water spots from our windows?
Light mineral spotting usually comes off in a standard pass. Deeper deposits that have started etching the glass need a one-time restoration step before regular cleaning begins. We will flag it on the estimate if your glass is in restoration territory, so you know what you are paying for.
Is the pure water system safe for plants and pets?
It is purified water with nothing added. No soap, no bleach, no degreaser. We still soak landscaping with regular water before and after the exterior pass, even with a chemical-free method, because we would rather overprotect the flowerbed than apologize for it later.
How tall a window can the pole reach?
The carbon-fiber poles we use reach around 30 to 40 feet, which covers virtually every two-story and most three-story residential homes in Cedar Park. If your home pushes past that, we will tell you on the estimate before you book.
Do we need to be home during the cleaning?
Not for exterior-only service. Interior cleaning requires access, so we coordinate a time that works. Our technicians text you on the way and walk you through the results at the end of the job.
