Gilbert's lake communities and heavy landscaping mean more irrigation per property than most of the Valley, and irrigation is what actually damages window glass here.
Pfaff Cleaning Co. is locally owned, with the owners overseeing every job. See our full process and service area on the main window cleaning page.
Prices below are for exterior cleaning, at our online rates, 15% off regular when you book online.
Price exterior, interior, screens, and protectant together in about a minute with the instant quote tool. A $150 minimum applies per visit, once for the whole visit rather than per service.
Interior and exterior glass, screens, frames, and tracks. Single story and two story. Hard water treatment where the deposits are still on the surface.
Cleaning glass is the visible part of the job, not the whole job. Tracks fill with desert dust that turns to paste the moment moisture hits it, which is why sliding doors get harder to move over the years. Frames hold dust that washes straight back down onto the glass with the next irrigation cycle. Screens hold a remarkable amount of dust and transfer it constantly.
Clean the glass and leave the rest and you have built in a re-soiling mechanism.
Mineral-heavy water landing on glass and drying in the sun leaves calcium and magnesium behind. Early on that deposit sits on top of the glass and comes off with the right treatment. Left long enough it reacts with the silica in the glass itself, and that is etching, which is a permanent change to the surface rather than something sitting on it.
The most common cause here is not rain. It is a sprinkler head hitting the bottom of the same window every morning. If you see heavy white buildup only on the lower portion of ground-floor glass, that is what is happening, and adjusting one head is free.
Cheap window cleaning stops at the middle of the glass. We take our time on the edges, corners, frames, and tracks.
Residential window washing is hand squeegee work. It is slower than spray and wipe, and it is the reason the glass does not streak in afternoon sun.
A squeegee also puts somebody within arm's reach of the glass, detailing the edge and the corners by hand. On a one or two story home that is the better result rather than a compromise. We do one and two story homes, and anything taller is a commercial method and a separate quote.
Streak-Free Guarantee. See a streak within 7 days? Call or text and we come back and fix it, no charge. It covers our work, not mineral we told you upfront would not come out, or glass that is already etched.
A flat price for a house means someone guessed, and guesses are padded. Pane pricing means you can count your own windows and know the number before anyone shows up.
What it covers is glass, frame and sill on each pane rather than a fast squeegee across the middle. Tracks are priced separately because they are their own job, and we would rather show you that than fold it into a number you cannot check.
Hard water spotting on glass is the one thing we are careful about promising. Deposit comes off. Etched glass does not, and we will tell you which one you have before you pay for either.
Gilbert water is moderately hard, lower than Chandler or Scottsdale but plenty hard enough to leave mineral deposits when it dries on glass in full sun. In neighborhoods like Val Vista Lakes and Cortina, higher ambient moisture near water features also contributes to spotting and to algae on shaded exterior surfaces.
Newer subdivisions further east tend toward larger window openings and two-story great rooms, which means more glass and more of it out of reach.
Gilbert's newer floor plans carry considerably more square footage of glass than older homes, so the small-home pricing tier rarely fits. We size the quote to the actual window count rather than the address, and you can get that number online before anyone comes out.
A streak within 7 days means a free trip back. Every time.

Yes, homes and commercial properties throughout Gilbert and the surrounding Valley.
Yes. Cleaning only the glass gives you a result that does not last, since dust on screens and frames transfers right back onto the pane.
Deposits still sitting on the surface usually come off. Once mineral has etched into the glass nothing removes it, and we tell you which you have before quoting.
If the area feels slightly rough under your fingertip it is likely etching. If it feels smooth but looks cloudy, the deposit is probably still on the surface.
Yes, we are equipped for upper-level glass so you are not on a ladder.
Twice a year works for most homes, after monsoon season and again in spring. Sooner where sprinkler overspray is hitting the glass.
Yes, counted as part of the glass on the property.
Exterior cleaning starts at $296.65 online for a small home, or $349 regular. Interior is the same price as exterior, so inside and out doubles the total. Screens are $15 each and glass protectant $13 per window per side, neither discounted.
