Print/Save as PDF

Maybe you’re noticing one window in your dining room has become foggy between the panes. Or maybe you’ve tried to open that one bedroom window, and it just won’t budge. 

Maybe you notice that one window frame is chipped. The caulking may be damaged, causing air to leak into your home. 

Many different types of damage can occur to home windows that may only be affecting one in your home. If it’s obstructing your view, deterring you from using it, or potentially posing a safety risk, chances are you want to replace that one window. 

That doesn’t seem too difficult, right? There are plenty of contractors out there that would replace just this one window, right? 

Yes, there are many contractors out there that will replace one window for you. However, there are a few things you need to know before meeting with a contractor and deciding to have one window replaced. 

At Southwest Exteriors, we have offered premium window replacements in San Antonio since 1989. We strive to meet your needs for your project, whether you are looking to replace one window or all the windows in your home.

Our representatives talk to many homeowners monthly about their one-window replacement project. While, yes, we can replace just one window for you, we want you to know a few things that come as a surprise to most homeowners about one-window projects. 

We want you to be aware of these few things if you are thinking of replacing one window in your home to have a better understanding of what you will get out of your project. 

This article will outline three things you need to know before moving forward with your one-window replacement project, like aesthetics, installation, and energy efficiency. 

After reading, you will understand what you will get out of your window replacement project and can make the best decision for your project going forward. 

#1. The new window will not look the same as the other windows

The first thing you need to know about a one-window replacement project is that your new window will not look the same as your other windows. 

For example, if you have a set of three windows in a front room of your home, and you are experiencing problems with the middle window, it will be noticeably different than the other two. 

Now I know what you might be thinking - “It’s just a window. How different can they all look?”

There are many design details on a window that differentiate from window type to manufacturer. Color, width, depth of the jambs, trim style, glass coatings, and the screen are just a few things that would be noticeably different. You can find a window that will look similar, but it will never be exactly the same. 

How your new window will look compared to your old windows is important to consider for how it may affect your home's overall look and aesthetics. 

If you aren’t too concerned with little differences between one window and the others, from the inside and out, then replacing one window may be the right choice to solve your problem. 

On the flip side, if you are very particular with matching in your home and do not like when something is out of place, then this is a large factor you will want to consider. 

If you are concerned one window looking different than the others will bother you, then you may want to consider replacing the set of windows where one damaged one was or all windows on that side of your home, depending on how particular you are. 

It is important for you to know that no matter how similar a window you find, it will still look different than your other windows. Depending on your preferences for aesthetics, this may or may not be an important factor for you. 

#2. The new window will be more energy efficient than the old windows, but will not solve the problem

The second thing you must consider if you’re thinking about replacing one window in your home is how different the energy efficiency between the new and old windows will be. 

To better understand what scenario you might consider energy efficiency, let me paint a picture for you. 

Say you have a set of three windows in your home office next to your desk. Every afternoon, the sun comes pouring through those windows, heating up the entire room. When sitting at your desk, the sun is hitting you through the left window, closest to the wall. 

You might think if you replace that one window where the sun is hitting you that it will keep you cool and help cool the room totally. However, this is not the case. 

Replacing one window in a room will not improve the energy efficiency as a whole when paired with old windows. That new window will have improved energy-efficient ratings because it has not been used, but it will not make the difference you are looking for to cool your room down. 

This is something to consider if you want to improve the energy efficiency of a room by blocking extra sunlight and UV rays. Replacement windows come with many options to improve energy efficiency, like varying Low-E coatings and shaded tints. 

If you want to improve the energy efficiency of one room, then replacing one window will not fix that. 

You also want to consider how that one window will be more energy efficient than the old windows that have been in use for many years. If your home’s windows are more than 15 or 20 years old, it may be more worth it for you to replace them all, or all in one room, to improve the overall energy efficiency of your home. 

#3. If you have stucco siding, stucco repair will increase the cost

The third factor to consider if you’re thinking about replacing one window on your home is if you have stucco siding. 

If you have stucco siding, a window replacement means you will need stucco repair to the exterior of your home. This will add to the overall installation cost.

Stucco repair around your window will also make a difference aesthetically and could make the difference of your new window stick out more. This, again, is a large factor to consider for the appearance of your new window and home. 

So, if you have stucco siding and are thinking about replacing just one window on your home, you will want to consider how it will affect the appearance of your home’s exterior and add costs. It may be more worth it for you to replace more than one window at the same time to save on future stucco repair costs. 

Should I replace one window or multiple windows in my home? 

Now that you know three of the largest factors to consider when looking to replace one window in your home, you can have a better idea of what to expect for your project. With your new knowledge, you can now also decide if you still want to replace just one window or potentially replace more windows in your home. 

If you are experiencing any issues with one window in your home, it is important to know what to expect with a one-window replacement project. 

Remember that your new window may look similar to your other windows, but it will never look exactly the same. This is important to keep in mind for the overall aesthetics of your windows and your home. 

Replacing one window also will not solve any energy efficiency problems in your home. And lastly, if you have stucco siding, keep in mind it can add to the cost for stucco repair. 

With Southwest Exteriors, we will replace one window if that is what you are looking for. However, some contractors have a minimum amount of windows that must be replaced for a project. This is something to keep in mind when searching for a contractor.

Overall, we just want you to be aware of the things you may not have known with a one-window replacement project. Now, you can have realistic expectations and make the best decision for your project. 

Before moving forward with your project, you might be wondering what all goes into the installation process of a window replacement. Then, if you’re thinking about replacing one window, you can have a better idea of what to expect. 

This article will outline the entire window replacement process with Southwest Exteriors, as well as what to prepare beforehand so you can learn about our processes and be more prepared for your window replacement project.
