How to know when it’s time to replace your windows

Windows, like anything else, have a life span. There comes a time in most homeowners’ lives when they will need to replace their windows. Unfortunately, not many people are aware of when this is necessary. Simply because a window appears in good shape does not mean replacing it is out of the question. There is much more to determining the condition of a window then the pane of glass itself. Knowing when to replace your windows can save you a lot of money and frustration, because neglecting to do so at the proper time can lead to costly utility and other repair bills. There are different reasons why a window might need replacing, so here are some helpful tips for making the determination.

Inspect the Glass and Frame>

By far the easiest and most effective way to tell if you need to replace your windows is to perform a simple inspection. If a leak is present, you will likely be able to spot it. Drafts are generally noticeable, but can be verified with a draft testing tool. These devices double as temperature readers as well, which can also give you insight as to whether the pane of glass itself is need of servicing. Over time, glass will deteriorate and become warped in areas. This thinning can significantly reduce a window’s ability to insulate. In addition, weather stripping is generally the prime culprit for heat loss. You will be able to tell quite easily if this is need of replacement simply by looking around the frame. If there are gaps present, or if you can see light at all, then you know new hardware is needed.

Does the Window Function Well?

Another easy way to determine whether a window needs replaced is to test its functionality. Does the window slide up and down with ease as it should? Does it seal up tight when locked? This last point is especially true for older windows. Before modern window technology was developed, traditional windows were equipped with ropes and weights to ease the sliding mechanism. It is common for these ropes to break, which can make opening and shutting the windows very difficult due to their weight. If you own a home with these types of windows and have experienced these issues, you can be sure that they will need to be replaced.

Replacing Your Windows: A Recap

For varying reasons, a home’s windows will need to be replaced at some point or another. The lifespan for modern windows is typically 30 years, but due to unpredictable circumstances, chances are you will need to replace your windows before they wear thin due to age. Whatever the situation, a damaged or broken window requires immediate attention. In order to ensure your home is being properly insulated from the elements and potential intruders, it is paramount that your windows are working in fully operational condition.

    After reading this, I think I may need to replace some of my windows. I own an older home that was built turn of the century. While I hate to get rid of the old charm, I don’t think my wallet would thank me. This is very relevant to me, because I do have the windows with the rope and weight system. One thing I would like to know is how I could go about fixing this? Does Clera provide service/repair work for these kinds of jobs?

    Where I can buy one of these testing tools? I am so grateful for technology. Our house has many windows, and I have been unable to find which one is leaking. There are probably a handful that need worked on, but I can’t seem to find where the problem is coming from. A helpful tip for anyone interested, which will work well with this tool. I have been busy Googling tips on how to insulate my home on the cheap. Bubble wrapping is supposed to work really well. I might have to test all my windows before applying the stuff to see how much heat really has been leaking out. This is the hard part about having so many windows. They are not energy efficient by any means and I can’t afford to dish out thousands of dollars right now.

    I have always wondered how glass warping worked. Is this due to improper installation do all windows naturally wear unevenly. I have not personally experienced this, but have heard about it. It would be nice to know so I can make the proper preparations for when I buy some new windows for my place.

    I think it might be time to replace my windows… The windows in my kitchen are always fogging up and the glass is cracked. I’ve had these windows for over 10 years, so I guess it should be time to get new ones. I know the windows from Clera are supposed to be very energy efficient… so I’m really excited about that. I’m looking for any way to save money on my energy bill. The awning windows look very nice.

    Aaron… I highly suggest giving Clera a call. These guys are an expert in windows and will install windows that are energy efficient. My kitchen windows were getting foggy like yours and I called Clera about four months ago. They installed new windows in my kitchen and they look so nice. I also noticed how much they help the ventilation. I don’t have to worry about my kitchen getting really smoky after I cook something.
