Please think about where you might have special circumstances and inform us ahead of time if possible.
Our standard cleaning is to use a soft cotton scrubber and squeegee. In Scott's experience including over ten thousand hours of cleaning windows (and according to manufacture cleaning specifications), our equipment and process do not scratch properly manufactured glass.
Be advised that some items such as paint will remain on the glass if the razor is not used. We're okay with this so long as you are okay with it.
The truth is that the more stuff that is on the glass the more aggressive treatment is required. For instance. blue painters tape has a mild adhesive, it is designed to be used on windows. Duct tape, by contrast, has a much stronger adhesive and is not suppose to be used on windows.
Happy Window Cleaning LLC is not responsible for any damage or scratches on windows that are defective from failures in the manufacturing process. It is the homeowner's responsibility to inform us if aftermarket tinting has been applied to the glass. That said we do not use razors except with implied permission to remove adhesives, and or paint, and even then it is Happy Window Cleaning's policy to do so with proper lubrication and technique., and to limit the use of razors to the areas where the sticker or paint is.
Further, It is the homeowner's responsibility to inform us if a single panel or more has been replaced with plexiglass instead of glass. Plexiglass is softer than regular glass. Our technicians are fully trained however we can not always detect such "booby traps". We are at your home to help you with your windows/problem. We ask you to own the situation If there are special circumstances that we cannot reasonably control.
If we are asked to clean a window that has duct tape on it, we will assume that you want the tape removed unless told otherwise. Removing duct tape does involve the risk of scratching your window, simply because the mechanical action required is more aggressive than usual. If that happens you must hold us blameless since we are responding to your problem the best we or anyone else can, and there are risks involved that we as the practitioner ought not to be asked to accept responsibility for, since they are beyond our control. This is what can happen when one seeks to remove items from glass that should not be present to begin with. The same can be said for paint, etc.
We have included a link to an article which does not represent the opinion of Happy Window Cleaning nor of Scott Britton. However, the article raises questions about replacement windows. We feel that our best client is a well-informed client.
Ultimately, it is your view that matters most. Pun intended. We're Happy but human, so there might come a time where a drip from the frame above, lands on one of our freshly cleaned windows. This could happen after we made the last "quality assurance" go around. Many things can happen in the field. Some of the things we've come across in the past are broken window seals, gaps in the trim that need paint or caulk. Our process is effective 99.9% of the time, however, you aren't a statistic, you're depending on us to see your viewpoint! But how will we ever know if there is a problem if you don't give us feedback? Lots of mediocre companies have minimally satisfied customers, that doesn't cut it with us. We crave for you to be Happy Customers. Things occasionally get missed by the best of us. That said, please let us know about any problem just as soon as it is discovered. No worries, no hassles, I will come back and make it right!
