Tips

How to know when to replace your windows

Determining when it’s time to replace your windows can depend on the specific issue you’re experiencing. If you have a broken window or damaged frame, you’ll likely want to take immediate action. If you’re looking to refresh your home you might take a little more time to decide.

Signs for replacing windows

Do your windows not open or close right? Energy bills through the roof? Are they an eyesore? Wondering if the issue you’re facing means it’s time for replacement?

Windows play a vital role in your home, providing natural light, ventilation, and a connection to the outside world. Recognizing the signs that your windows are due for replacement can save you from potential headaches and help maintain your home's comfort, safety, energy efficiency, and value.

So, when is the best time to replace your windows? Here are some common issues where it’s time to replace your windows.

Broken or damaged windows

If you’ve got a broken window or there’s visible damage to a window frame on the exterior or interior, it’s time for replacement windows. Broken windows are dangerous, and any opening can allow water to seep in, which can lead to mold and mildew issues. Damaged window frames can also invite pests, and some pests, like termites, can severely damage a home. 

Water issues

If you notice water stains or signs of wood rot on window frames, it’s time to replace your old windows. Wood rot is either white/wet rot, brown/dry rot, or soft rot. White/wet rot is whiteish or light yellow and will feel spongy. Brown/dry rot turns wood into a deep brown color. Soft rot leaves a honeycomb-like appearance on wood and is mostly found on fallen trees. But if conditions are right, like extreme temperatures, it can appear in homes.

Drafty windows

If you can hear a slight whistle around your windows, you likely have a draft. You can also check for drafts by holding your hand at the top or bottom of the window sash where it meets the frame. If you feel air on your hand, you have a drafty window.

High energy bills

One of the most common reasons homeowners opt for window replacement is to improve energy efficiency. If you notice a significant increase in your energy bills or feel drafts near your windows, it could be a sign that your windows are no longer effectively insulating your home. Newer windows often feature advanced insulation technologies, such as double or triple glazing, low-emissivity (Low-E) coatings, and gas fills between panes, contributing to better energy efficiency.

Visible wear and tear

Over time, windows can show visible signs of wear and tear. Cracked or rotting frames, peeling paint, and warped window sashes indicate that your windows no longer function as they should. These issues can compromise both your windows’ functionality, as well as the beauty and safety of your home.

Difficulty operating

Windows that are difficult to open, close, or lock pose safety concerns and can be frustrating to deal with. If you find yourself struggling to operate your windows or notice that they no longer stay open on their own, it's time to consider something better. Modern windows have user-friendly features like easy-to-use locks, smooth operation mechanisms, and even motorized options.

Condensation and moisture

Condensation between window panes or on the interior surface of the glass can indicate seal failure. When seals break, moisture can enter between the panes, leading to foggy windows that obstruct your view and reduce insulation efficiency. If you notice condensation or fogging, it's a sign that your windows' seals have deteriorated, and you should look into replacing your windows.

Noise and comfort issues

Your windows should bring the light in and help keep the noise out. If the outside noise is too loud, your windows might not be providing proper sound insulation. Newer windows are designed with insulation features that significantly reduce outside noise, keeping your home quieter and more comfortable.

Outdated style and curb appeal

Your home’s curb appeal matters. Not only for your own enjoyment but also for potential resale value. Unfortunately, outdated or mismatched windows detract from the overall aesthetic of your house. Replacing your windows lets you upgrade to a style that complements your home's architecture and enhances curb appeal. Homeowners often like to swap out windows with patio doors for more functionality, natural light, and wider views. Crank windows also might be easier to operate for some people than double hung windows that need lifting to open. Homeowners can recoup 61-68% of a window replacement cost when you sell your home.

Foggy window glass

When the temperature difference between the indoor and outdoor panes of glass increases and the humidity in your home reaches certain levels, windows and doors start to show condensation. Condensation is an accumulation of saturated warm air on a cooler glass surface.

Condensation on the outside of your windows should not raise alarm. If you notice condensation on the inside of your windows, it means your windows are leaking air and/or your home is humid.

If you see condensation between the panes of glass in your double or triple-pane windows, or have foggy windows, it means that the air-tight seal has failed, and insulating gas has escaped. You can check your manufacturer’s warranty to see if seal failure is covered. If it’s not covered, you might need to replace your windows.

Windows won’t open or close

If your windows won’t open or close easily, it’s time to replace them. Using a book to keep a window propped open isn’t a long-term solution for old windows. The years of opening and closing windows do add up and can eventually cause cracks on the window frame. Dust and dirt can accumulate as well and make windows difficult to open and close. A poorly functioning lock can prevent proper sealing. It can be one of the first signs that it’s time to replace your windows.

What to consider when choosing windows

Learning more about different window frame materials, window types, window glass options, and window replacement costs can help you focus your search.

Window frame materials

Common window frame materials include: wood, vinyl, aluminum, and fiberglass. You might favor one material over another for aesthetics. You might also like one material more because of its durability. Infinity Ultrex® fiberglass provides the best of both worlds with its strength, beauty, and low maintenance.

Window replacement cost

Window replacement costs vary based on the size of your project and the options you choose. The best way to think about the cost of replacement windows is to set a budget. A budget can help you narrow your search for a window replacement company. It also helps window companies work to provide what you want within those parameters.

Things to know about replacing windows

As you start to seriously consider replacing windows, you’ll have more questions come up. An Infinity consultant can answer all your questions, but here are some helpful tips on frequently asked questions.

Should I replace my windows all at once?

Some homeowners prefer tackling their entire window replacement at once. If your home has a lot of windows or budget is a factor, you may want to consider approaching your project in phases over a few years.

How do you measure for new replacement windows?

Knowing how to measure for new replacement windows can help you as you begin gathering quotes. Measuring windows means recording the width, height, and depth. A Infinity consultant will measure your windows for accuracy. They will verify each measurement before sending your order to our factory.

When’s the best time to buy replacement windows?

The best time to buy replacement windows is when you’re ready. Window installers experience busier times during the spring and summer in some parts of the country. But installers can also have more work during winter months in warmer climates.

How to prepare for window replacement?

The best thing to do to prepare for window replacement is to move furniture, drapes, and other items away from your windows. You should also remove pictures, fixtures, and air conditioners near the windows. Plan to keep pets and small children away from installation areas. You can do other things, like telling your neighbors about installation day and disabling any alarms.

Benefits of replacing your windows

If any of these signs are too familiar, it’s probably time to replace your windows. Quality windows aren’t always the cheapest, but they have many benefits.

Easy maintenance and durability

Older windows often require regular maintenance and can become difficult to open, close, or clean. Modern windows are designed with easy care, featuring materials that resist warping, fading, and corrosion.

Increase home value

Window replacement is an investment that can yield impressive returns. Modern, well-designed windows enhance your home's curb appeal and value.

More natural light

Old windows — especially vinyl — hinder the amount of natural light in your home. By replacing them with larger, more modern windows you can flood your interiors with sunlight.

Noise reduction

If you live in a noisy neighborhood or near a busy street, new windows with soundproofing features can significantly reduce external noise.
