Vinyl Window Casing: Removal and Installation Guide [2025]

A significant advantage of modern vinyl windows is their ease of maintenance. Unlike wood, PVC doesn’t need to be scraped or repainted; it doesn’t darken, warp, or discolour with age, meaning your vinyl windows will look the same even 20 years after installation. 

Another advantage of vinyl replacement windows is that these units create a seamless look on the inside of your home thanks to vinyl window trim.

However, if you need to repaint the walls inside your home, you may need to remove the casings from your windows to create a clean look. The good news is that the casing on replacement vinyl windows is designed for easy maintenance so you can remove it and put it back on in seconds.

The Ecoline team has prepared a video showcasing the best practices for removing and installing vinyl casing to keep your windows look terrific.

Here are some steps to follow to make sure you remove your vinyl window casing properly:

• Using a flat screwdriver or a chisel, find the edge where the interior window casing meets the wall. Slip the chisel in and make a small separation.
• Continuously separate the casing away from the wall down the whole length.
• Once there is enough separation, the casing around windows can be easily removed by hand.

Steps to consider when doing vinyl casing installation:

• Start by inserting one of the lengths into a corner piece.
• With the corner attached, find the beginning of the casing channel and gently push the edge into the groove.
• Line up the whole casing against the groove.
• With a hammer or mallet, lightly tap against the entire length of the window casing until it is flush against the wall.
• If window casing installation is done properly, there shouldn’t be anything visible past your casing.

Safety Precautions When Installing Window Casings: All You Need to Know

When handling window casing replacement or installation, safety should come first. 

• Before diving into the job, clear the area around the window. This ensures you have ample space to work and minimizes the risk of tripping over obstacles. 
• It is also advised to wear protective gloves when removing the exterior or interior window casing. This not only safeguards your hands from potential splinters or sharp edges but also ensures a firm grip. 
• Always use the right tools for the job. A wrong tool can damage the window trim, leading to unnecessary expenses. When installing modern exterior window trim, make sure you follow the manufacturer’s guidelines. 

Remember, the goal is to enhance your home’s beauty without compromising on safety.
