Most screens have little effect on the natural light and view in a room, but they can enhance your environment by providing fresh, bug-free air. However, window screens don’t last forever. Look out for these common signs that tell you it’s time to replace a window screen.
Window screens rust and deteriorate slowly over the years due to constant exposure to the elements. Window screens in the shade may last longer than those in direct sunlight. We recommend replacing window screens every 10 years.
One of the main purposes of a window screen is to protect your home from pests and debris while you enjoy the fresh air. A warped or damaged screen makes it difficult to open or close the window. If you notice any decrease in window functionality, it’s time to replace the screen.
Constant exposure to sunlight and ultraviolet (UV) rays will cause your window screen to fade or discolor. Faded screens are vulnerable to additional damage, and they can diminish your home’s curb appeal.
Window screens help block the sun’s rays, which can lower your home’s cooling costs during the hot summer months. If your energy bills start to creep up, examine your window screens and look for damage or fading.
Holes or tears in window screens form due to bad weather, insect damage, old age, and a number of other factors. Rips and tears prevent your screen from doing its job. When you see visible signs of damage, it’s time for a replacement.
Most window screens have a protective coating that helps block UV light from entering the home. Shiny screens have lost this protective coating and need to be replaced.

GET QUOTEReplacing a window screen is a relatively simple DIY project you can do over the weekend. Most homeowners pay $20 to $80 for DIY window screen replacement. However, costs depend on the materials and the type of screen. Follow the steps below to learn how to replace a window screen yourself.
Before you replace your window screen, figure out what type of material your screen is made of and purchase a replacement in the right size. The most common screen material is fiberglass mesh. Other popular options include aluminum screens and solar screens.
This material is the most affordable and easy to install. Fiberglass comes in several different colors, such as gray and charcoal/black.
Aluminum works for most projects and is less visible. It is durable and resistant to sagging. Aluminum screens come in bright or charcoal/black finishes.
This type of screen material is the most energy-efficient and blocks heat, UV damage, and glare from the sun. Because it blocks out light, it can help protect your curtains and carpets from fading while providing additional privacy.
A security screen uses stainless steel mesh to prevent forced entry while providing ventilation.
There are various window screen types available through top window brands. Popular types of window screens include the following:
This type combines two overlapping window screens and expands to fit your window. Adjustable screens work even without a frame.
This is the most cost-effective and basic window screen. They’re easy to install and remove but susceptible to damage.
Full screens cover the entire window, while half screens cover a portion of the window. Casement windows often have full screens; double-hung windows typically have a half screen on the lower sash. Half screens aren’t as effective because they don’t cover the entire window.
This screen type has a self-storing design that can roll up or fold away when not in use. Retractable screens can be applied to almost all
types of windows
, including casement windows and double-hung windows. These are more expensive than flat window screens and more challenging to install.
Take frame and window measurements to ensure you buy the right size screen. If the screen is 36 inches or taller, it must have a center support to prevent bowing. Window sizes vary, but the average size is 18 inches by 20 inches to 36 inches by 74 inches. Screens outside of this size range require a custom order.
Here is a list of supplies you’ll need to replace your window screen:
Brick
Clamps
Roll of window screening
Scissors
Screen rolling tool
Small flathead screwdriver
Spline
Utility knife
Remove the frame from the window and place it on a flat work surface. Use a flathead screwdriver to remove the spline around the perimeter of the frame. The screen spline is a cord, typically made of vinyl, rubber, or foam, around the screen that secures the mesh screen to the window screen frame. If the screen frame is made of wood, the screen is typically fixed to the frame with staples or nails. Use your screwdriver to remove the staples or a claw hammer for nails.
Dispose of the old screen. Replace the spline if it looks brittle or old. You can find replacement splines at most home improvement stores. Make sure to purchase the right size. Splines are measured by diameter and need to be thicker than the grooves in the frame. Measure it yourself or bring the old spline to the store when buying a replacement.
If the window frame is dirty, wash it before installing the new screen. Dirt and pollen can collect in the corners and creases, and installing a new screen is easier when there’s no debris. Make sure the frame is completely dry before installing the new mesh.
Roll out the new screen mesh over the window frame. Leave an extra 2 inches of mesh material on all sides to ensure a secure fit. Use your scissors to cut the screen to size for a perfect fit.
Pull the new screen tightly over the frame and use a clamp or tape at the top and bottom of the frame. Next, take the screen rolling tool and use the convex wheel (which is grooved outward) to push the screen into the grooves of the frame. Secure it to the frame by pushing the spline into the channel using the convex side of the spline roller. If you have a wood frame, staple the mesh or nail it with wire brads.
Keep the material taut over the frame but don’t over-stretch the material. If it’s too loose, the screen will sag. If it’s too tight, the tension can damage the sides of the frame. One way to ensure a taut fit is to place a brick or heavy object in the center of the screen after rolling in the screen on two adjoining sides. After installing the mesh along the two remaining sides, remove the brick. If you notice wrinkles or bulges in the mesh, remove the spline and try again.
Use your utility knife to trim the excess mesh along the new spline. Angle the blade of the knife away from the spline to avoid damage. If you’re installing a wooden frame, take this time to secure loose joints, fasteners, or screws.
Put the new screen back into the window.
DIYers who feel comfortable with simple home improvement projects and have the required tools can likely handle rescreening on their own. Replacing a window screen is a quick DIY job, but sometimes it’s better to call a professional. A professional window installation contractor can help save you time if you have several screens to repair. You may want to hire a pro if you need a custom screen or you’re using material that’s difficult to cut. Labor costs $15 to $50 per screen, excluding materials.
Your window screens protect you and your home against insects, debris, and harmful UV rays. If your screen is damaged or shows signs that it’s past its prime, follow the simple steps above to replace your window screen.
DIYers can learn how to replace a window screen, but if you need several replacements or have custom window screens, we recommend calling a pro for the job.

Yes, you can replace just the screen on a window versus the entire frame. This involves cutting out the old screen and replacing it with new mesh material. This is a straightforward home improvement project that most homeowners can do on their own, plus it can help save you money.
The best way to clean a window screen is by washing it with warm water and dish detergent or soaking it in a solution made of one part vinegar to three parts water. Take the screen out of the window, apply the cleaning solution to both sides of the screen, and use a sponge, microfiber cloth, or soft-bristled brush to gently scrub the screen and frame. Rinse the screen and let it completely dry before placing it back in the window.
How you install a new window screen depends on the screen and whether you have a full screen or a half screen. If you have a full screen, you must remove each window sash to get to the screen. Take the screen and insert the top into the upper window track. Push the screen up from the bottom to compress the springs and insert the base into the lower track.
