How Often Should Commercial Windows Be Cleaned?

Michigan Commercial Window Cleaning

Regarding Commercial, Retail, Office, Medical and High Rise Window Cleaning Scheduling

There are three main considerations when scheduling window washing frequency; aesthetic appeal / image and prevention of glass surface damage.

  • Location
    Height above ground, street/sidewalk proximity, vehicle and pedestrian traffic all are significant factors affecting effective window cleaning frequency. Landscaping, sprinkler systems and building architecture also all play a role.
  • Environment
    External impacts such as exposure to wind and rain and the intensity thereof, the amount and composition of airborne particulates and organic vapors are all significant factors; in addition building design and facade materials also effect the glass and can cause glass surface damage that may be very expensive to remediate if not properly maintained.[1]
  • Image
    Now more than ever people will form an impression of the establishment they are entering even before even opening the door.  Crisp, Bright and Clean windows send a message to Customers, Clients and Employees and answer unspoken questions in their minds.  Such appearance considerations are particularly a factor when a presentation of cleanliness and/or financial stability and trustworthiness are desired such as in Restaurants, Health Care Facilities, Insurance/Financial Institutions and Professional Offices.
  • Budget
    If a constrained budget is an issue; Neglect may be far more expensive mid-long term, than appropriate maintenance[2] It may be possible to design a glass maintenance program which addresses all of these concerns and considers your budget.  Please call Great Lakes Window Cleaning, Inc. (517-482-4040) for a consultation.

Fact Sheet: How is Great Lakes Window Cleaning Different?

Michigan Commercial Window Cleaning

Answer: It’s our People, Our Standards & Our Systems!

The People of Great Lakes Window Cleaning

Best Window Cleaners

Our People make all the difference;  if you take a look at our window cleaners, you will notice we have responsible & experienced adults working with us.

We don’t hire high-school kids or seasonal help to clean your windows; on average our window cleaning technicians have over 10 years window cleaning experience (some 15-20+ years) and are clean cut, drug and smoke free, professional Window Cleaners (check it out here), accustomed to working in many of the area’s premier homes and offices.

It takes over a year for us to consider a window cleaning technician trained, even more so for a residential window cleaner; so temporary – seasonal help is out of the question.

 Great Lakes Window Cleaning Standards:

Application Process & Pre-Employment Screening

It all starts before a candidate even fills out an application; we have a pre-application agreement covering such items as grooming and professional behavior expectations.  All candidates go through multiple interviews, and successful applications are fact checked, with every former employer and personal reference contacted.  If everything checks out, the candidate’s background and criminal records are checked.  When a job is offered the Candidate is sent for their first drug Test.

 Great Lakes Window Cleaning Systems;

Well Trained Professionals

Window Cleaning Lift TrainingOur training starts with a 13 week structured window cleaning and customer service training program; including several workbooks, videos and A LOT of hand’s on practice and mentoring.  Our training program for new window cleaners covers everything from how to hold the window cleaning tools and chemical safety to how to use ladders, along with sessions titled “what good customer service is” and ” how to behave in a professional manner while on the job”  It often takes well over a year before we consider a Window Cleaning Technician “trained”, and a few years before considered fully proficient in window cleaning.


Because we try to provide a livable wage, fair benefits and a good work environment; we’ve been able to retain our experienced window cleaners and have a very low employee turnover.  On average our Window Cleaners have over 10 years window cleaning experience, many have been with us for decades!  There is no substitute for the Window Cleaning Experience and Training our Window Cleaners bring to your job site or home.

Our Employees are an asset to, and contribute to our community
