5 Signs Your Home Needs New Windows

Monday, June 4th, 2018 by Sabrina Hunter

Well designed windows play an important role in your home. They can improve your home's curb appeal, allow more natural light in your home and improve energy efficiency.

If your home is more than 20 years old with wood or aluminum framed windows they probably cause problems unnoticed by the owner. Weathertite Systems has listed signs to look out for when your home's windows are due for an upgrade.

Window Operation

Check each window for smooth operation by opening and closing it. Windows should open and close seamlessly without too much effort. If you need to apply extra force to open your windows or if they are painted shut, it is time to replace them. These issues are common with wooden windows.

Decaying Frames and Leaky Windows

Decaying window frames can affect the smooth operation of opening and closing your window. Wooden window frames are exposed to moisture resulting in warped frames. Moisture damage can cause more decay. If your window frames show signs of decay then it is time to upgrade the window.

If you notice water leaking through your windows or in the worst case a pool of water on the floor then you have leaky windows. Ignoring the problem of a leaky window with towels is not going to fix the problem. Remember mold growth loves moisture no matter how little it is, so don't delay in replacing that window. The two common reasons for leaky windows are poorly installed windows or a failed sealed unit.

High Energy Bills

Do you have old single-paned windows? They are more susceptible to leaks while newer windows are designed to be watertight. There are a few ways to test your windows for energy efficiency. Hold a candle by the window frame and as you slowly move it around the window edge watch the flame to see if it flickers. This is a sign that draft is coming through the windows. On a cold day touch your window pane. If it's cold then all that lovely heat from your furnace will be lost within a few feet from the window. Try standing next to the window in a T-shirt on a cold day. If you feel cooler than in other areas of the house this is another sign you need to update your windows.

Windows with low-emissivity (Low-E) can help keep the heat out in the summer and heat in during the cold months. Low E glass can help to reduce your annual heating and cooling bills.


Can you hear the sound of a car coming from the down the street? Single pane and even double pane windows will allow the sound to vibrate in your home. The build-up of traffic noise can be hard for a homeowner to ignore. The best energy efficient windows can help to increase noise reduction in your home.


Do you notice condensation or fog build up on your windows? There are different types of condensation depending on where it is appearing. The only time condensation is a problem if it appears between the glass panes, that can eventually lead to leaky windows.

The recent change in energy efficiency technology has improved windows durability, aesthetics and functionality. Whether you are thinking about improving your home's appearance, reducing heat or cooling loss from your home, newer windows can add value.
