Energy Savings5 Signs You Need New Windows

New windows and renovations will always be necessary eventually. When was the last time you checked the condition of yours?

If your home has aluminum or wood-framed windows, you may not even notice the problems they cause. Homes that are over 20 years old with the original windows are typically due for an upgrade, but there are some easy ways to check. How will you know when it is time to replace your windows? 

Well-designed windows play a variety of important roles and improve your home’s curb appeal, increase the amount of natural light in your home and improve energy efficiency. If your windows are run-down and damaged, they will not only be a security issue, but the overall comfort of your home becomes a problem. It’s crucial to identify whether your windows need to be replaced and there are many signs around your home that will clearly tell you that it’s time to start your window renovation plan. 

Here are the top 5 signs you need new windows.

High Energy Bills

On a cold day, stand next to your windows. Does it feel cooler than the rest of your home? Touch your windows. If the glass feels cold to the touch, the warm air from your furnace is being cooled down as soon as it gets within a few feet of your windows. Not only is this uncomfortable but it’s such a waste! 

Grab a candle or burning incense stick. Hold it by your window frames and slowly move it around each corner of the window. If the candle flickers or the smoke moves, drafts are travelling through your windows. Really bad windows will have visible light coming through the frame in spots when you try this in the dark with a flashlight. Just imagine how much warmer and comfortable your home would be if all those little holes were sealed up.

As the temperature drops during winter and rises during the summer, your heating and cooling bills are sure to do the same. If your windows are on the older side, it’s likely that much of the heat produced by your furnace and the cooling from your air conditioner is going to waste. While older windows are generally single-paned and vulnerable to leaks, newer windows are highly efficient and designed to help prevent air from transferring in and out of your home. 

You should consider replacing those leaky windows with windows that contain argon gas and low-emissivity (LoE) glass to save on heating bills. LoE glass can keep heat in during the winter and out during the summer, greatly reducing your heating and cooling costs and provide a more comfortable living space year-round. 

Window Operation

Walk around your home to open and close each window to check for smooth operation. If it requires a bit of force and pressure to open or if they're painted or swollen shut, it's time to replace them. Wood windows can be particularly bad for this. Opening your windows should not be a chore or a source of exercise, they should open and close effortlessly.

Decaying Frames and Leaky Windows

One of the clearest signs that you need to replace your windows is decaying window frames. As wooden window frames are exposed to moisture, they can begin to go on a downward spiral. Built-up moisture damage can also cause more serious decay down the road, causing severe safety issues. If you notice that your window frames show signs of decay, this is a sign that your windows are in serious need of an upgrade.

You may also notice that you have windows that are leaking, otherwise known as leaky windows. In some cases, your windows may be leaking so bad that they are leaving a pool of water on your floor. Yikes! 

You may be thinking that there isn’t enough water leakage to justify the renovation or that the leaking will stop in the summer. When you’re making your decision to replace windows, remember that moisture fuels the growth of mold, despite how little water there may be. The longer you postpone replacing your windows the better chance the leaking window will generate a major problem.

Two of the most common reasons why your windows are leaking are due to poor installation or a failed sealed unit. You might be asking, "Well can't they just be repaired?"

You could repair your windows but you wouldn’t be fixing the problem. Think about it this way, your leaking window is a problem, but it’s not THE problem. Moisture built up on your windows is a symptom of something more significant. The only way to truly fix leaking windows and ensure that the windows won’t fail again is to replace them.


Take a moment to stand quietly by the window and wait for a car to drive by. Can you hear it coming from down the street? Single-pane windows or even double-pane windows will transfer sound vibrations from the street into your house. Before you know it, all the noise will add up and you can wave goodbye to the peace and quiet.  The best energy-efficient windows will absorb these sound waves before they enter your home. 


Do you regularly see fog or condensation building up on your windows? You will need to analyze which kind of condensation you are dealing with because not all condensation is bad. Depending on where it is appearing on the window, it may not be a cause for concern. However, if you do see condensation in between the two panes of glass, this is a sure sign that your windows' seals have failed and it's time to replace them before your windows get too leaky. Learn more about the types of condensation and various solutions to combat the problem. 

Although separate from each other, your windows, doors, heating or cooling system, insulation, ventilation, and siding make your house operate as a system. In order to keep your home operating at peak efficiency, all factors need to be functioning together in order to achieve the best return on your investment.  

Windows are an investment that will boost your home’s value and significantly improve your home’s curb appeal. They will also increase the amount of natural light in your home, soundproofing and increase energy efficiency. Windows are a functional upgrade and whether you are simply trying to improve your home's appearance or save money on your energy bills, window renovations are a great project that is sure to pay dividends.
