8 Tell-Tale Signs That Your Window Needs Replacement

When the window’s damage is visible to the naked eye, you know it’s time to replace it. Unfortunately, these indicators of a faulty window aren’t always observable or physically evident to the average homeowner.

If you have a nudging gut feeling that there’s something wrong with your current windows, you’ll want to act fast. In some cases, you’ll experience that initial uneasy feeling when a sudden draft of cold air passes through your window cracks, causing your home’s residents to shiver unexplainably. Similarly, you may notice intensifying sounds coming from outside, i.e., children at play, barking dogs, passing cars, etc. Under these circumstances, take a closer look and investigate the root cause of these disturbances.

If you suspect that your window needs replacement, a wood-munching pest may be to blame. For instance, a rodent can widen these unsealed cracks and crevices, allowing cool/hot air to enter your living spaces.

Should your home experience a severe infestation, you’ll need to consider investing in pest treatment services before replacing your window so that you can avoid recurrent damage. Left untreated, these rodents and insects can continue to damage your window frames, unscathed.

If you’re not unfamiliar with the tell-tale signs of window damage, here’s is a list of potential red flags that will signal when it’s time to replace the window:


If you see moisture on the window, it means that the seal has failed. Unfortunately, there’s no way you can eliminate these tiny water droplets forming on the surface of the glass without swapping out the entire window frame. Don’t overlook excess moisture signs, as these minuscule droplets could eventually lead to mold and mildew formation.

Drafts of air

Drafts of cold and warm air are also a tell-tale sign of window failure. While many of us choose to ignore these drafts, experts believe that these cool breezes and gusts of hot air pass through your window’s cracks and crevices, spiking your monthly energy bill.


Problems with insulation will also cause energy bills to rise. The easiest way to tell if the insulation has failed is to touch the window frame. If the window feels very cold in winter and warm in summer, it’s time to replace the insulation.

Single-pane windows

If your home has single-pane windows, you’ll likely feel the temperature variations during the cold winter and hot summer months. In most cases, single-pane windows are found in older homes and historic buildings, as double-pane or triple-glazed windows have rendered these archaic models obsolete. If you’re the owner of a historic home, make the switch to double-pane or triple-glazed windows and benefit from their energy efficiency.


While most of us will catch the faint sound of a car horn or barking dog while puttering around the house,  you should start thinking about changing the window if you find yourself constantly annoyed by sounds of birds chirping and children playing outside.

A high-quality window should be able to absorb everyday noises, allowing you to live comfortably and sleep soundlessly. On the other hand, a defective window will invite sounds of sprinklers, roaring highways, dribbling basketballs, and neighbors passing by.


Moisture, wind, and other environmental elements can cause irreparable damage to even the best windows. If the window’s base shows signs of decay and mold, change the window before it starts to damage the walls and the surrounding structures.

Curb appeal

Curb appeal often plays a pivotal factor in homeowners’ decisions to switch their windows. If your windows look outdated and don’t match your house’s trendy exterior, it’s time to replace windows. By swapping out the old models, you’ll start to notice a steady decrease in your energy bills. Hand selecting windows that enhance the property’s exterior can also boost your home’s resale value, translating to a larger profit.

UV rays

If you notice visible changes in the color and texture of the furniture and carpets exposed to the sun’s natural light, this discoloration and wear-and-tear is likely due to penetrating UV rays. Unfortunately, older window models aren’t designed to block the sun’s rays. However, Low-E glass, laminated, and tinted windows will offer protection and prevent discoloration, saving a homeowner money otherwise spent on repair costs and replacement furniture.


When choosing windows for your home, be sure to research models that will stand the test of time. To further extend the lifespan of your windows, hire pest control experts who can apply professional-grade pesticides and ward off household pests known to inflict property damage.
