How to Install a Window

If it is time for you to look into residential windows replacement you may be wondering what you need to do to install a window. There are many reasons homeowners need to install new windows, such as wanting to replace old, leaky windows for greater energy efficiency or simply wanting the fresh look a residential glass update can give a home. Whatever your reason, read on to learn the basic components and steps of window installation.

Know the relevant window components

As with any home remodeling project, there is a new set of vocabulary to learn. Here are the main terms to know for residential windows: 

Jamb – The main vertical parts forming the sides of a window frame.

Sill – The window sill is the surface at the bottom of a window.

Head – The window head is the horizontal piece at the top of the window frame  

Frame – The combination of the head, jambs, and sill that forms an opening in which a window sash fits.

Sash – A window sash is the part of the window that holds the glass and the framework around the glass to keep it in place.

Parting bead or parting strip – A parting bead is the thin piece used to separate two adjoining sashes. 

Stop – A window stop is a narrow strip that holds a window sash in position in a window frame.

Prep for Installation

Now that you’ve done your homework, you are ready to start installing your new window by first taking some measurements. When you measure your window, keep these tips in mind to get the most accurate dimensions: 

• When measuring the width, measure from one jamb to the opposite jamb at the top, middle, and bottom of the frame. Use the narrowest measurement of the three.
• Similarly, when measuring the window height, measure from the top of the sill to the bottom of the head at the left edge, middle, and right edge. Again, use the shortest measurement of the three. 
• For all measurements, measure from the inside of your house. 

Now it is time to remove the old window. Start by removing the sashes, parting bead, and stops. If they are not damaged, you can set these parts aside to be used again. To finish up, clean the window jambs and fill any holes with caulk. 

Install your new window

Center your new sashes in the window frame making sure the mounting holes on the sides are visible. Place a layer of caulk on the window head before positioning the top sash. Use the mounting screws to affix the sash to the jambs, being careful not to screw too tightly which can damage the jambs. Now use the new sashes as designed to be sure they work smoothly and there are no gaps. If your window works as intended, add a layer of caulk inside the window to reinstall the stops.
