Checklist: It’s Time to Replace Your Old Windows in Downers Grove



Window replacement often gets left on the back burner until the existing windows are no longer doing their job adequately. Therefore, timing is one of the most important factors to consider when you’re planning a window replacement project. But in order to get the timing right, it’s important that you’re able to recognize the signs of window failure.

Sure, smaller common issues can be fixed. However, if the windows have been installed for over two decades, you might want to examine them for the root cause of any recurring problems. This will help determine if they can be repaired or need to be replaced.

Here is a checklist of tests that can be carried out to help you decide if your Downers Grove home needs new windows or window replacements:

Conduct a Draft Test

This is the most vital test for any window, as an unsealed window will affect the performance of your HVAC unit, resulting in higher utility bills. To begin the test, move a lighter or a candle all around the edges of the window. If the flame curves or wavers, there is likely an insulation issue with the window that should be examined by an experienced window installer.

Check the Weather Stripping

Weather stripping is prone to wear and tear, and it’s important that you examine it thoroughly. Worn out weather stripping can contribute to drafts being let in through the gap between the sash and the frame of the window.

Examine the Ease of Operation

Test to see if all the handles, cranks, and latches are operating smoothly. Extreme temperatures can cause the window frames to contract and expand, which can change the fitting proportion, cause imbalances, and lead to jamming and sticking over time. Additionally, moisture can also play a part by causing rust and rot formation.

Examine the Window Frames

The elements of nature, along with time, can cause the window frames to warp and deteriorate. Check the corners and the joints of the frames to see if they are still in good working condition. This is especially true if you have old windows with wooden frames, as they are more prone to rot and deterioration.

Look Through the Glass

If the glass panes are broken or cracked, the window will need to be replaced immediately. Often times, the crack in the glass might not be visible. However, if you notice condensation or fog on your windows, this could indicate a leak caused by a minor crack in the panes. Unfortunately, even a small crack can adversely affect the overall efficiency of the window.

Inspect the Caulking Around Your Windows

Caulking is the seal that is applied continuously around the perimeter of your window. It is one of the fastest components to deteriorate, but also falls into the category of quick repairs that can be fixed easily. If you see areas that need to be re-caulked, they should be addressed quickly. This is because broken seals allow cold and heat to escape from the house, which wastes energy.
