Window Cleaning Checklist

Homeowners should clean their windows twice a year, in the spring and fall. Be sure to clean the following areas:

  1. Screens
    1. Removable Screens: Remove screens, take outside, spray with cleaning solution, allow to soak for a few minutes and then rinse using a low-pressure sprayer. “A dirty screen traps dust, dirt, pollen and other allergens, but a clean window screen can help keep the air flowing into your home cleaner.” (Source: Pella)
    2. Interior Mounted Screens (Nonremovable): Vacuum with a soft brush attachment and/or wipe with a solution of soap and water.
  2. Frame: Wipe down the interior frame of the window and remove any debris.
  3. Panes: Clean the inside and outside glass utilizing a cleaning method, solution and tools designed to prevent leaving streaks.

Tips for clean and streak free windows

  1. Be extra careful when cleaning glass that is tinted or reflective. “On a reflective glass surface, damage is more noticeable, and scratches can result in coating removal and a visible change in light transmittance. Cleaning tinted and reflective glass surfaces in direct sunlight should be avoided.” (Source: All Weather Windows)
  2. Be sure not to use excessive cleaning solution and to remove all from the window as if residue is left on the window it can cause damage.
  3. Avoid ammonia or alcohol based glass cleaners.
  4. Never use a razor or any type of blade to scrape windows.
  5. Avoid cleaning windows on hot sunny days as the cleaner may dry on the window before you have a chance to remove it, leaving stubborn streaks which are hard to remove.
  6. Vacuum or sweep up grime in window frame before using a cleaner to avoid a muddy mess.
  7. Choose a good window cleaning solution to dissolve dirt so it may be wiped away.
  8. Use a lint free cloth
  9. A handy tip from Good Housekeeping to identify whether streaks are on the inside or outside of the window, “When you’re cleaning, wipe one side of the window horizontally and the other vertically. If any streaks do form, you’ll easily know whether they’re on the outside or the inside.”
  10. Rather than cleaning all of your windows on one day, make this job easier by doing windows floor by floor, or room by room. This way, by the time you get to the last window, you won’t be as tired as if you did the whole home in one day.
  11. Clean window in an S-shape to remove dirt and grime and avoid smears.
  12. Hire a professional.

Hiring a Professional

If you are considering hiring a professional to clean your windows, there are two methods often used to provide window cleaning quotes:

  1. A count of the number of windows on the front of your home multiplied by 4 (to estimate the number of windows on all 4 sides of your home).
  2. Quoting based on the square footage of your home.

Below is a rough estimate of what you can expect to be quoted by a professional to clean the inside and outside of your windows based on the square footage of your home:

Square Feet

Number of Windows Average Price


10 $185
1,500 15


2,400 24


3,200 32


4,200 42


Companies providing window cleaning services will often provide a quote based on one of the above pricing models, and then upon arrival at your home to provide the service, the technician will conduct a visual inspection of your home for the number, size and location of windows and advise at that time if the estimate needs to be adjusted.

Your estimate may need to be adjusted if:

  1. Your home has larger windows than the average home
  2. Your home has more windows than the average home
  3. Your windows are very dirty due to not being cleaned for a long time or living in an area with construction
  4. Your home is over two stories
  5. Windows and/or skylights on the second floor and above are hard to reach
  6. You would like to clean glass patio doors, glass shower doors, glass railing on stairs, and other areas
  7. Your home’s windows are complex:
    • Windows with many sections (panes) separated by trim cost more to clean than similar-sized windows with no trim.
    • Decorative windows
    • Sunburst windows

Advantages of Hiring a Professional

  1. Saves you time.
  2. If you don’t have the tools to do this yourself, then it saves you money by not having to purchase all the proper tools needed.
  3. By hiring a professional you can schedule regular cleaning of your windows, which will extend their life and.
  4. Professional window cleaners will have the proper equipment to harness up, safely climb ladders, clean second floor windows and so forth, saving you the stress of climbing ladders and working at high heights.
  5. A professional will have more experience in cleaning windows in order to do a good job and leave your windows streak free.
  6. This is also a good opportunity to have gutters and the exterior of your home cleaned if your window cleaner offers this service.

We utilize a Water Fed System to clean your window. First we use a wet brush to loosen dirt on the window panes and sills. We then rinse them using highly purified de-ionised water. Because the water is pure, it leaves no marks when it dries. You can think of it like the “spot free rinse” at the drive through car wash.

Water fed cleaning systems with extendable poles work very well on two storey homes as they eliminate the need for ladders, save time and significantly reduces the risk of injury and damage to the property.

Plus we don’t use any harsh chemicals or cleaners, instead using an effective eco-friendly method which works.

Window cleaning may not be your favourite task to do in the spring, but once completed you will be sure to enjoy improved air quality, extra sunlight, unobstructed views and more.
