Have you already had a window inspection before your windows were cleaned? This can be a relatively quick inspection and can be performed by a member of NEGSA who is familiar with this type of preliminary inspection. The purpose is to locate any defections that should be brought to the attention of the "building owner" before the windows are cleaned. Such as surface inclusions, mineral deposits, obvious scratches or even cracks, delaminations, or negative deflection.
The final inspection should be done after the windows are professionally cleaned because it is only then that most defects become obvious to the trained eye. Some of which can be dealt with at the time of discovery. Others cannot. Also certain defects might come under the warranty. If it is still extant. If indeed this is the case the building owner will absolutely want to address the condition.
As explained in a previous post in this blog, point indent fractures of PIFs can cause the entire window to crack and even break into two pieces if pressure is applied. While these cannot be "fixed", they can be made invisible by covering them over with some type of signage. If no one even knows they are there no one will press on them with their finger. The effect is usually immediate. Further if the IGU Insulating Glass Unit is already experiencing pressure because of negative deflection, it wouldn't take much to trigger an implosion.
The bottom line here is to first have your windows cleaned and then routinely maintained by a professional. They should be inspected before the window cleaning, and then afterward they should have a very thorough, detailed inspection. Once this is done the same window cleaner that you used for the preliminary inspection and window cleaning, will be able to keep up with the routine inspections, every time the windows are cleaned/maintained.
My intent and purpose which I am moving ahead with through NEGSA, is to educate as many window cleaners as possible with at least a rudimentary knowledge of the technology of window inspections. Because the purpose is to promote preservation. No one wants to replace their windows if there isn't any insurance or warranty coverage. The expense is just too great. Also if breakage occurs at a business site you could be forced by law to replace. Such things can be avoided. With the correct knowledge and guidance.
So the next time you happen to look out your dirty windows don't think only that they would look so much better if they were sparkling clean, but rather they should also be inspected, professionally cleaned, and then inspected again for longevity and preservation!
