Window Cleaning Services in Tucson Arizona

How Our System Works

Water is pumped through a hose reel, up a telescopic Water Fed Pole and through jets in the brush where it is sprayed onto the glass. When the brush contacts with the surface of the glass and frames, it lightly agitates the surface, loosening the dirt. Any dirt or dust particles are flushed away by the constant stream of water.

What Would Happen If Normal Tap Water Were

Used to Wash A Window?

It will result in the glass appearing milky white in color when it dries, and you will be able to write your name on the glass surface with your finger. Try it! This effect on the glass is due entirely to the mineral content of the tap water.


If you were to buy bottled spring water from the supermarket and read the analysis label you will notice that water contains minerals such as calcium, magnesium, chlorides, nitrates, sulphates, bi-carbonates, sodium, potassium and silica etc…that are dissolved in the water.

A New Level of Clean

For Your Windows

In addition to using the traditional squeegee glass and window cleaning method, a division of Paragon Peak Building Maintenance also utilizes new technology known as the RO & DI water fed pole system and because of our filtration process all glass cleaning is done using purified and deionized water only.

All water from out of a tap contains a quantity of minerals. The quantity differs from one area to another based on of the variety of  specific environmental and ground rock strata that rainwater passes through before it reaches our rivers and ground-water storage reservoirs. In Arizona, especially Tucson & Phoenix mineral content is extremely high and leads to hard water build up over time if windows are not cleaned properly.


Our method not only uses Reverse Osmosis to purify and filter the water, but we go one step further, after the RO filtering the water is then run through a Deionizing (DO) filter leaving water almost 100% pure h2o.


What this means for you is cleaner windows and glass without streaks or hard water spots. Another benefit to this system is because the water used to clean your windows was purified in the beginning your glass will stay cleaner longer because it is not attracting as much dirt as it otherwise would.


If you would like to learn more about how this system works please continue reading below.  

Clean windows allow natural sunlight in your office building and reduce pollutants caused by dirty window sills and dusty frames. In addition, having your windows cleaned quarterly extends the life of the glass. So, how does our window cleaning service work? Well, contact our experts today and specify the type of cleaning you wish them to do for your windows. Based on your requirements, our experts would offer the best window cleaning services. The service charges would obviously depend on the type of or the amount of cleaning done and the number of experts hired to clean the windows.

Paragon Peak Building Maintenance

Paragon Peak Building Maintenance, a renowned window cleaning company in the greater Tucson & Phoenix areas offers window cleaning services for all sized buildings. Our services include:

Reverse Osmosis (RO)


Reverse Osmosis uses a very fine filter or membrane. The membrane is so fine that the pores only allow passage of water molecules. The dissolved impurities do not pass through the membrane. These impurities can include calcium, sodium, and other elements that normal water can contain. The membrane itself is made from a synthetic material, such as polyamide or polysulfone. This membrane is delicate and could be damaged by organic matter, iron, chlorine, and other impurities found in normal tap water. These impurities must be removed by pre- filters.


This membrane, begins as a large flat sheet, and then is spiral wound into a tube , and housed in a pressure vessel. The pressure of the water entering the vessel is sufficient to squeeze the water molecules through the membrane to produce a flow of pure water. The remaining water passess through the vessel carrying the impurities with it and exits to waste. This is known as reject.

The reject water has a higher content of dissolved solids but is not hazardous and can be safely drained away.

Deionized Water (DI)


Deionized water (DI water or de-ionized water is water that lacks ions, such as cations from sodium, calcium, iron, copper and anions such as chloride and bromide. This means it has been purified from all other ions but H3O+ and OH-, but it may still contain other non-ionic types of impurities such as organic compounds. This type of water is produced using an ion exchange process.

Deionized water is similar to distilled water, in that it is useful for scientific experiments where the presence of impurities may be undesirable.

The lack of ions also causes the water’s resistivity to increase. Ultra-pure deionized water can have a theoretical maximum resistivity up to 18.3 M-·cm-1, compared to around 15 k-·cm-1 for common tap water. Deionized water’s high resistivity allows it, in some very highly speciallized instances, to be used as a coolant in direct contact with high-voltage electrical equipment. Because of its high relative dielectric constant (~80), it is also used (for short durations) as a high voltage dielectric in many pulsed power applications, such as Sandia’s Z Machine.

Deionized water easily changes pH while storing it. This is because carbon dioxide from the air dissolves in the water and causes a drop in pH by forming carbonic acid H2CO3. Boiling the water will remove the carbon dioxide to restore the pH.

The uses of ultrapure deionized water are many and varied, often having application in scientific experimentation such as when very pure chemical reaget solutions are needed in a chemical reaction or when a biological growth medium needs to be sterile and very pure. DI water is also used extensively in the semiconductor industry to process and clean silicon wafers and sometimes in the optics industry when very highly clean optical surfaces are required for coating.

DI water is also often used as a final rinse when washing scientific glassware. Deionized water is very often used as an “ingredient” in many cosmetics and pharmaceuticals where it is sometimes referred to as “aqua” on product ingredient labels. This use again owes to its lack of potential for causing undesired chemical reactions due to impurities. A recent use of DI water is that of window cleaning where because it contains so little dissolved solutes so the glass dries without leaving any spots.
