700 dollars per window?

Yes.  And maybe more.  If the window cost two thousand to replace.  And you are the only one that can safely remove the stain, etch, scratches, concrete sealant, paint, hard water spots, and so on.  There are so many windows now that simply cannot be scraped without leaving scratches.  Windows with defective surfaces and windows with low e titanium dioxide coatings.  There are many metal coated windows like this out there.  None of them can take a razor without scratching, unlike smooth glass.  Many have coatings that are so transparent they are almost impossible to locate.  What happens when this kind of window is coved with silicone caulk, paint, or something else?  According to GANA the window is essentially wasted!  In other words it is in need of specialty restoration work.  And you can almost name your price.  Depending on whether you have the answer and what the window cost to replace!

I remember running into a building in PA once that had been treated with a silane concrete sealant.  Every window was covered with this sealant.  It could not be scraped.  Because the razor would not remove the sealant.  Simple enough.  This was one of those specialty restoration jobs that I just mentioned.  It could have been safely restored/cleared with a cerium oxide and a rotary polishing pad/machine.  But instead hydrofluoric acid was used.  For a "quick fix".  The dark glass was severely etched.  It became wavy and dimpled.  Fourth stage dynamic etching.  Now the glass could NOT be restored.

To restore the building properly each window would have required at least a solid hour to efficiently and completely clear.  Then the glass would have needed a hydrophobic glass sealant.  But that didn't happen.

A Glass Smart Technician would have been able to perform the work without completely wasting every window beyond repair.  If this building were under the care of such a company the problem would have never happened.  Because the owners would have consulted with that window cleaner before contracting out the work of sealing the concrete.

So go out there and make money.  But more importantly educate your existing customers.  Protection believe it or not is actually more profitable most times.  Because by pricing by the square foot to apply the proper glass sealant, coupled with minimal time per window, your profit per hour can be substantial.  Especially if you repeat every six months or once a year.

Send me an email and we can talk more.  Would you like to know more about the specialty uses for cerium oxide?  Where to buy a good brand?  What you should pay?  And how to use it efficiently?  Then keep attentive to these posts.  I will be writing a lot about the use of specialty superabrasive powders like cerium oxide.  Especially now that I am working with the Window Cleaning Resource (WCR) officially.
