A Savvy Homeowner’s Guide to Window Screen Maintenance

Written by KC Glass on . Posted in Blog

When you perform outdoor home maintenance, you may spend more time on your siding than on your window screens. Because window screens don’t need constant refinishing or replacement like some of your other outdoor elements do, you may forget about them entirely.

However, well-maintained window screens are essential to keep your home beautiful and protect your household from insect infestations, debris, and excess heat.

In this blog, we discuss the importance of healthy screens, common types of screen damage, and ways to keep your screens functional.

Why Do Intact Window Screens Matter?

While it’s true that window screens may not always be your highest priority, it’s important to keep your screens intact and in good condition. High-quality window screens provide the following benefits.

Controlled Heat Transfer

Some window screens are designed to offer a small amount of supplemental shade during the sunniest part of the day. These screens reduce heat transfer, making it easier for you to control your indoor temperatures. Additionally, these screens protect your walls, upholstered furnishings, and other belongings from fading due to sunlight exposure over time.

Improved Airflow and Ventilation

Few experiences feel better than a cool breeze coming through an open window on a hot summer day. Window screens allow you to benefit from natural ventilation without inviting leaves, dust, and other unwanted debris into your home.

Lower Risk of Window Breakage

While a screen cannot protect your window from stray baseballs, window screens do reduce the risk of breakage. The screen provides a layer of protection from storm debris and other objects that would otherwise hit the glass directly.

Reduced Risk of Insect and Rodent Infestation

Windows are one of the most common entry points for pests, especially windows located on the basement and ground floors. Strong window screens make it more difficult for insects and rodents to infiltrate your home.

Any type of damage can render your window screens ineffective.

What Are the Most Common Types of Screen Damage?

Your screens can become damaged in several ways. Most types of screen damage require full replacement of the screen in question, though some minor issues can be repaired by a qualified contractor.

The most common types of damage are as follows:

  • Brittleness. Over time, window screen mesh can become brittle due to exposure to high levels of sunlight and extreme temperatures. These screens become inflexible and may even crumble when handled. Once a screen becomes brittle, it needs to be replaced. These screens can begin to look shiny as they age.
  • Dents. When hit with an object, some window screen materials can develop visible dents. These dents can develop into holes or tears over time. If you notice large dents, consider replacement.
  • Rips. Screens can tear due to impact or accidents like brushing a lawn tool over the window screen. Small holes may be able to be repaired through a localized melting process that closes the puncture.(delete.  I’ve never heard of this) Large rips, however, require replacement.
  • Sagging. If your window screen is not the right size or old, the frame or mesh may begin to sag. Warped frames must be replaced with frames of the correct size while droopy mesh should simply be re-screened.

Once your screens become damaged, you may need to replace them completely or have a contractor re-screen the frames.

How Can You Maintain Your Window Screens?

If you want to keep your screens in good condition, start with regular cleanings. You should clean the screen frame every time you clean your windows and perform thorough cleanings at least twice a year.

Frame Cleaning

When you wash your windows, use a damp cloth to wipe the outside of your window screen frame. Look for any signs of warping or corrosion, such as bent areas or rust spots. Dry the frame with a cloth.

If you notice that the screen itself has become dirty, but you aren’t due for another deep clean for a while, use a stiff-bristled brush to clear away any grime.

Seasonal Cleaning

For thorough cleaning, remove your window screens and lay them flat. If you work with multiple screens at once, label each screen and the window it belongs to since even similar-looking screens may have different dimensions.

Use a handheld vacuum attachment to get rid of most of the buildup on the screen. Then, wash both sides of the screen with water and all-purpose soap. Prop the screens up vertically and rinse them with your hose. Allow the screens to dry completely before reinstalling them.


The next time you make a home maintenance to-do list, put your window screens at the top to ensure that your home stays in great condition from the outside in.
