Full Frame vs Insert Window Replacement: What You Need To Know

By Christian Raab

Is Your Home Letting in Problems You Can't See?

You’re not imagining it—your home feels drafty, your energy bills keep climbing, and that one window won’t shut all the way. You know it’s time to replace your windows, but with so many options out there, it’s hard to know which method is best. Homeowners often consider insert window replacements, which are generally quicker and less disruptive than full frame replacement, making them an appealing option.

I have talked to many Wichita homeowners, and I know it can be overwhelming!

Many homeowners are being sold insert windows. Insert window replacements are installed within the current frame if it is in good condition. They sound quick and cheap, but they may be covering up bigger problems. Early in my career, I worked for a contractor that did this kind of window replacement. I was shocked at how quickly we could remove and install new windows. There were three of us, and we could replace the windows in a 2000 square foot home in about 1-2 days. Insert replacement can often be completed in just a few hours, while full-frame replacement may take several days. I thought it was really awesome!

As I grew in my knowledge of construction, I soon realized that pocket windows, in many cases, are covering up problems. Many issues with windows are not just about the window itself but also the frame around it, the lack of insulation between the window and framing, and the rot on the framing around the window. The pocket window method does not reveal any of these problems. Insert replacements do not address issues with the entire frame. A full-frame window replacement allows for a complete inspection and repair of any water damage. Full-frame replacement involves removing the entire existing window, including the frame, to allow for a more thorough installation. This method can provide better insulation and is effective for improving energy efficiency.

The Real Problem: Insert Windows Don't Address the Frame

Insert (or “pocket”) windows slide a new window inside your old window frame. That sounds convenient—until you realize:

• The old frame could be rotted, moldy, or poorly insulated, and you would never know! Insert window replacements often retain the existing sash, which may hide underlying issues.

• There’s no way to inspect or repair water-damaged framing.

• Your new windows are only as good as what’s underneath them.

With insert window replacements, the new window is inserted into the existing frame, rather than replacing the whole frame. The fit of the new window within the existing frame (how the window fits) is crucial for performance, but may not address deeper structural issues.

Limitations of insert window replacements:

• Insert window replacements typically only provide new sashes and hardware, not a full replacement. That’s like putting new siding over rotten framing—it looks good now, but the hidden damage keeps growing. By contrast, full-frame window replacement ensures that the framing and insulation are properly addressed, minimizing heat transfer and improving long-term energy performance.

At Pinnacle, We Take a Better Approach: Full-Frame Window Replacement

Here is our process:

Pinnacle specializes in full frame replacement windows, which involve removing the entire window and frame for a more durable and comprehensive solution.

Our full frame window installation process begins by carefully removing the existing window and frame, allowing for a thorough inspection of the window opening and the installation of a new frame. This method replaces the entire existing window and frame, not just the sashes, ensuring a clean and long-lasting result.

Full frame replacements are ideal for situations where the window opening or the window's size needs to be changed, such as in older homes or when upgrading to a different style.

Full frame window replacements provide the opportunity to upgrade to a variety of replacement window styles, such as casement windows, bay windows, or awning windows, depending on your home’s design and ventilation needs. This can also include options for both windows and doors.

Pinnacle offers a wide selection of custom windows and doors to suit various architectural styles, ensuring both functional and aesthetic enhancements for your home. We use only the highest quality materials for every project, ensuring durability, superior insulation, and an elegant finish that enhances your home’s beauty.

Why Wichita Homes Need This

After 15+ years remodeling homes in Wichita, Andover, Derby, and surrounding areas, here’s what we’ve seen again and again:

Choosing the right window replacements is crucial for Wichita's climate, not only for comfort and energy efficiency but also to reduce your home’s carbon footprint over time. Picking the right option can improve energy efficiency and comfort.

Replacing old or damaged windows can address issues caused by harsh weather, such as drafts, leaks, and rising energy bills. When considering window replacements, homeowners can choose between full-frame and insert options. Insert window replacements are a great choice if you want to preserve the existing interior trim and framework, maintaining the original look while upgrading performance.

1. Wichita Weather Is Brutal on Windows

Sun, hail, wind-driven rain, and freezing temperatures create wear and tear—especially around old wood frames. Insert windows, ignore that.

2. Many Homes Built in the ‘70s–'90s Used Cheap Windows

Many homeowners are now looking to replace windows that were not built to last 40+ years. Full-frame replacement helps upgrade your home’s protection and extend its lifespan. The improved insulation and airtight seal of a full-frame installation can lead to significant energy savings.

3. You Want It Done Right the First Time

Our process ensures nothing is missed—no hidden rot, no air leaks, and no cutting corners. Just solid craftsmanship.

Full-frame replacement provides greater customization options, allowing changes in window size or style, such as upgrading to single hung windows or other styles that complement your home’s personal style and functional needs. In contrast, insert replacements may only provide new sashes and hardware, rather than a full upgrade to a different window style.

Exterior Trim Considerations: Why Details Matter

When it comes to window replacement, the details around your windows can make a big difference in both curb appeal and long-term performance. One of the most important—but often overlooked—details is your exterior trim. The choice between full frame window replacement and insert window replacement has a direct impact on how your exterior trim is handled.

With full frame window replacement, the entire window—including the frame and exterior trim—is removed. This allows you to update or refresh the look of your home’s exterior, whether you want a modern style or to restore classic charm. This allows homeowners to coordinate with other exterior upgrades, such as refreshing vinyl siding, for a cohesive and weather-resistant exterior.

Full frame replacement also allows for the installation of new, properly sealed trim, which can help prevent water intrusion and improve energy efficiency.

On the other hand, insert window replacement keeps your existing window frame and exterior trim intact. This is a great option if your trim is in good condition and you want to preserve the original character of your home. However, it also means that any issues hidden behind the trim—like rot or poor insulation—may go undetected. Homeowners who have maintained their vinyl siding may find that it pairs well with insert replacements, but it’s still important to ensure the framing behind the siding remains in good condition.

Ultimately, your decision should be based on the condition of your existing window frame and your goals for your home’s appearance. If you’re looking for a fresh start and improved protection, full frame window replacement is the way to go.

If you love your current exterior trim and it’s in good shape, insert window replacement can offer a less disruptive solution. Either way, understanding how each method affects your exterior trim will help you make an informed decision that fits your style and needs.
