Can You Stop Windows From Leaking? What causes it and how to fix it.

Why should you care about Window Leaks?

Windows play a crucial role in maintaining a comfortable and livable environment within a home. They not only provide a source of light and ventilation but also serve as a protective barrier against the elements. When a window is damaged or poorly installed, it can become a source of headaches for homeowners. 


Window leaks are persistent, harmful problems for homeowners, as leaks can result in water damage to walls, floors, and even the foundation. The tell-tale signs of a leaky window are often subtle, but with a keen eye, you can spot the problem before it requires a costly repair. Here are some key indicators of a leaking window.


Indicators of a Window Leak

  1. Water stains

Water stains on the walls or floors near a window are an obvious sign of a leak. They typically appear as dark brown or yellow stains and, in extreme cases, cause paint to bubble or chip. If you notice water stains, address the problem immediately to prevent further water damage.


  1. Warping or rotting window frames

Another sign of a window leak is warping or rotting window frames. If your window frames are made of wood, they can become waterlogged and rot. This ultimately causes the frames to warp, making it difficult to open and close the window. If you notice warping or rotting in your window frames, it's time to reseal your windows or, depending on the severity, replace them entirely.


  1. Condensation on the inside of the window panes

Condensation on the inside of your window panes is another indication that your window is leaking. When warm, humid air comes into contact with a cold surface, such as a window, it can cause condensation. If you notice condensation on the inside of your window panes, address the problem as soon as possible to prevent water damage.

  1. Drafts coming from the window

A draft or slight breeze from the window can indicate that your window is leaking. Feel a draft coming from your window? Air is likely spilling in. Not only can this increase your energy bills, but it can also make your home less comfortable. If you notice a draft coming from your window, take action.


What Causes a Window to Leak?

There are several reasons why a window might leak. One common cause is a lack of proper maintenance. Over time, the seals around the window can become worn or damaged, allowing water to seep in. Especially if you live in a region with heavy rainfall, make sure your window seals are in good condition. It's also important to make sure windows are properly installed to prevent leaks.


Another common cause of window leaks is a failure in the window's design, such as poorly installed flashing or a lack of proper drainage. For instance, water can seep in behind the window if the flashing is not installed correctly. Similarly, if the window is not properly sloped, water can collect around the window, eventually making its way inside and causing water damage to your home’s structure.


Why it's Important to Fix Window Leaks

It's crucial to address water damage caused by a leaking window as soon as possible to minimize the risk of further damage to your home. The longer you allow water to seep into the structure of your home, the greater the potential for expensive repairs down the line. Furthermore, if the damage is left unchecked, it can even lead to the need for a costly remodel.


In addition to structural complications, untreated water damage can also lead to health hazards associated with mold growth. Mold can also cause irreversible staining and discoloration of your walls and ceilings. Mold can be particularly frustrating for homeowners who have taken great care to maintain the appearance of their home, only to have it tarnished by a simple leak.


Insurance claims related to water damage are often subject to scrutiny. Many insurance providers won’t cover the repair cost if a lack of maintenance caused the damage. In other words, it's in your best interest to take care of any leaks as soon as you spot them.


When to Replace Windows

If you've noticed a leak in your window, address the problem promptly. In some cases, you can fix the problem by simply resealing the window. However, damaged or rotting window frames may require full window replacement. 


When deciding to repair or
replace a window, consider the window's age and the extent of the damage. For example, if the window is 10-15 years old and the damage is significant, replacing the window may be more cost-effective than repairing it. Similarly, if the window shows signs of wear and tear, like cracking or warping, it may be time to replace it.


Energy efficiency is also essential. Are your windows old and not energy efficient? Replacing your windows with energy-efficient panes can help reduce your energy costs and make your home more comfortable.

Nobody likes dealing with clogged gutters. They’re messy, smelly, and usually result in one or two unpleasant pest encounters. Gutter guards are a great way to prevent clogging by keeping all the leaves and debris out of your gutter troughs. But how do you know which guard is right for you?

The upfront cost is the biggest benefit of opting for window repair instead of replacement. Window repairs are cheaper in the short term, especially when only one or two windows are damaged. Ultimately, repairs can work for quick fixes like replacing a pivot bar or shoe on a window that won’t stay open or installing a new window screen.

Measuring window screens is more complicated than just length and width, however. You also need to account for depth, not to mention adjusting for hardware space and making sure your screen will fit over the lip of your window (the U-Channel) when installing. What measurements you need to grab also depends on your window type. Consider this your step-by-step guide for measuring window screens, regardless of whether your windows are double or single-hung.

Brick exteriors offer a beautiful curb appeal to a home, but they can feel limiting when it comes to your ability to renovate. Many brick homes in Arkansas are older, which may mean they also come with outdated and drafty windows. If you’re a brick house homeowner, you may be wondering if it’s even possible to replace these windows with better, more energy-efficient ones.

During the freezing months of winter, it’s common for icicles to form along the gutters and roofline as condensation drips off your roof. This can not only create a safety hazard around your home, but it also can lead to significant damage to your roof, gutters, and even foundation once larger icicles begin to melt and form puddles around the base of your home.

Double-hung windows are one of the most popular styles among homeowners today, preferred for their dual combination of aesthetic appeal and practical functionality. If you’re considering double-hung windows in Arkansas but aren’t sure what to expect, we have you covered with this complete guide. What are Double-Hung Windows? Double-hung windows feature two vertically sliding sashes, giving you more flexibility in how you open your windows to let in the fresh air. When it’s time to install new windows , many homeowners opt to upgrade to double-hung windows because they offer so much more variety in use and design. All of our custom vinyl double-hung windows include the popular tilt-in function to make cleaning even easier and keep your perspective crystal clear! Single vs. Double-Hung Windows Single-hung windows often look similar to double-hung except for one key difference: they only have one sliding panel, leaving the other fixed in place. A similar type of window you may be familiar with from your days in rental homes and apartments is the sliding window, where a single panel moves side-to-side while the other remains static. The ability to move either panel and tilt them in for cleaning makes double-hung windows a much better option in most homes—especially for second-floor windows! Double-hung Windows vs. Casement Don’t confuse double-hung windows with casement windows! This is a common misconception because double-hung windows can tilt inward for cleaning. Unlike casement windows—which open outward using a crank mechanism—double-hung windows are sliding windows that move up and down along a track. They are typically only tilted for cleaning purposes, not for ventilation. Benefits of Double-Hung Windows High-quality windows should always have sturdy manufacturing, thick glass, excellent energy efficiency, and custom sizing. High-quality double-hung windows include a few other benefits that make them the best choice for most windows in your home that aren’t specialty pieces like statement geometric windows or bay windows. Ease of Cleaning When your home has windows that don’t tilt inward on high floors, cleaning becomes more of a high-risk task for doing it yourself. This means either hiring professional window cleaners, living on the dangerous side or accepting the fact that your windows will be dirty. When you opt for double-hung windows, cleaning is a breeze! All you have to do is lock the windows in place before tilting the panel toward you to wipe clean from the safety and comfort of your home. Better Air Flow Thanks to both panels sliding vertically, your home will have quick and easy ventilation and airflow without sacrificing energy efficiency! Our double-hung windows are extremely sturdy and durable, so you don’t have to worry about drafty windows impacting your energy bills. Simple Opening and Closing Double-hung windows sound more complicated than they are! They operate much the same as single-hung or slider windows—the only real difference being that both panels can move. When you invest in high-quality double-hung windows, they are designed to slide with ease while maintaining a tight, sturdy seal along the tracks. Aesthetically Stunning Double-hung windows are a classic style that works for any home. They can come in a variety of shapes and sizes to accommodate your unique situation, elevating your home with plenty of natural light and unbeatable curb appeal! Frequently Asked Questions About Double-Hung Windows: Still have some unanswered questions about double-hung windows and how they might work for your home? Here are a few we’ve heard a lot: Can double-hung windows have screens? Yes, you can have screens on double-hung windows. Because the windows only tilt inward, they work well with exterior screens to keep the bugs out while letting the cool air in. Are double-hung windows secure? The security of your windows depends in large part on the quality, not necessarily the style. Our double-hung windows are made with the highest quality materials, ensuring a tight seal and unbreakable lock. They cannot be tilted inward from the outside, so you don’t have to worry about that easy-cleaning feature compromising your safety. How do double-hung windows work? Moving your double-hung windows—whether tilting to clean or sliding the panels up and down—all comes down to the simple locking mechanism: To slide window sashes along the track for opening, turn the lock. Pull down on the top sash or up on the bottom sash to slide your window open vertically. To tilt one of your sashes in for cleaning, turn the locking mechanism and gently pull the sash toward you from the opposite end.
