Get an In-Person, On-Site Estimate

Of course, this process can all be simplified by bringing the professionals to your home or office for an in-person estimate in the first place. They have the expertise in counting windows as well as the equipment and staffing the job calls for.

Counting your own windows can be tricky and likely lead to an inaccurate quote. No one likes to be surprised with a bill that’s much higher than anticipated. Relying on the professionals to provide you with an accurate bid is always the best option.

Not All Windows Are the Same

The reason this can be confusing for customers is that there are several different shapes, sizes, and types of windows; they may be reachable from ground-level or may require a ladder or lift. Those differences could affect the window count and estimate. Some windows have multiple panes of glass, while some have specific designs. Some are arched windows in the entryway above a door, while some are part of the door itself.

So how do you know how to count windows for cleaning? Let’s break it down.

What Counts as One Window?

Depending on the size, you can sometimes assume that windows with a single pane of glass are one window. Casement windows are a common example. Those arch windows and door windows we previously mentioned are both likely considered to be single windows as well. Windows with cut-ups are more complex. These are often considered one window, but it would be important to note for the cleaning company since each pane would be cleaned individually.

What Counts as Multiple Windows?

There are several types of windows that a home or business owner might assume are one window but are actually multiple. For example, French doors, sidelights, or, as previously mentioned, windows with cut-ups. Bay windows are another common type that invites confusion. While you see it as a single bay window, there are three windows that make up a bay window.

What is the Best Process for Counting?

Once you become familiar with the kinds of windows you have in your home or office building, it is important to count windows for cleaning companies clearly and correctly. The process for doing so seems simple, but it is important to provide as much information as possible.

First, be sure to go in order and write down your count as you go. It could be helpful to start at a front or back door and work your way around in one direction. When you start, be sure to keep those determinations for what counts as one window or multiple. Another key is to be as detailed as possible about the type of windows you have. Do you have French doors? Do you have storm windows or stained glass? Are the windows on the first, second, or third story? These specifics will allow the company to better understand the job and provide a better estimate.
