So you are ready for the window replacement project. Window replacement, especially in the midwest, is one of the most effective ways to weatherproof your home. Getting rid of old windows and installing new energy-efficient ones will also enhance your curb appeal, increase your home value, and save you money in the long run. Let’s not forget about the good old mother Earth and the significance of sustainability.
Incorrectly measured windows can be a costly and time-consuming mistake. Before beginning the window replacement process, it is essential to order the correct dimensions that will fit like a puzzle. Taking initial measurements of your windows will also help in determining a cost estimate for the entire project. While the task is not difficult in itself, it does require a level of precision on your part, as accurate measurements are crucial.
Why Should I Replace My Windows?
Window replacement goes beyond the aesthetics of your house. Windows perform many functions that we tend to overlook, such as keeping the weather out. If your windows are leaky and bring moisture inside the house, that alone is a recipe for disaster. Inviting moisture into your home through windows that lack an appropriate waterproof barrier can lead to mold or rot, among other issues.
Another reason why your windows may need replacing is draft. If your heating is working properly but you continuously find your home chilly, it could mean your windows are to blame. Once homeowners replace their windows, they may suddenly notice that utility bills are lower. When you have drafts due to poor windows, your HVAC system is overloaded with work, and you can’t even feel the warmth.
What About My Window Frames?
The wooden frames around your windows need to be inspected, preferably by a skilled professional, to ensure that they are in good condition and can support your new windows. If there are signs of water damage or rot, the structure might not be suitable and would need a new construction window.
Let’s get to measuring your windows.
Checking Window Corners
Making sure your windows have the perfect 90° angles in the corners is what we call checking for squares. If your existing window frames are in good condition, you should be fine. However, if any of your window frames are lopsided, you might have a problem when opening the newly installed windows.
Get hold of your measuring tape by placing it diagonally inside the upper left corner of your window to the lower right corner. Carefully record the measurement and repeat in the other diagonal direction. If your numbers match or are within ¼ inch of each other, your window frame is in a suitable condition to receive new windows.
Measuring Your Window Width
Once your window frames are square, it’s time to measure your window width. To make an accurate measurement, you can check the width in three places of your existing window – the top, the middle, and the bottom. Refresh your knowledge of window anatomy, and place the measuring tape against the window jamb. Here are different window models and how to measure their width:
- Awning or Casement Windows – measure the width in a horizontal fashion from one trim to the other at the center.
- Double-Hung, Single-Hung – single and double-hung windows are measured in the middle from one trim to the other.
- Sliding Windows – trim to trim in the center of the window
- Bay or Bow Windows – bay or bow windows are measured separately at the center of each window panel. It may happen that the middle panel has different dimensions, so make sure that each measurement is taken accurately.
Measuring Your Window Height
Again, for more accurate measurements you might consider measuring the window in three places, from top to bottom on the far left, middle, and right. Here’s how to measure different window models:
- Casement or Awning Window – measure your window panel by extending your measuring tape in a vertical position trim to trim.
- Double-Hung or Single-Hung Windows – measure your window vertically from trim to trim.
- Sliding Window – the height is measured from the middle.
- Bay or Bow Window – measure the height of all bay or bow window panels separately at the center and record your measurements.
Is Depth Of The Window a Problem?
In most cases the depth of your window is not an issue when it comes to taking accurate measurements. It may happen that a depth is too narrow for your replacement window, which may be the case for some mobile or modular homes. Your new window will need at least 3 ¼ inches to fit. To measure your window depth, measure the space of the sill from trim in the back to trim in the front when your window is open.
What If My Window Measurements Differ?
Check all your written down measurements and see which panels are shorter than the other. Round your shortest measurements down to the nearest ⅛ of an inch. With the final measurements you can order your new replacement windows.
