There are different installation methods for windows, but homeowners will essentially need to choose from one of two options: retrofit windows, which are windows built into the existing window frames, and full frame windows, sometimes referred to as “new construction.”

Full frame window installation involves the complete removal of existing window units, including frames and trims, and replacing everything – including the siding surrounding the window with the new window. It is often pursued for comprehensive upgrades or significant stylistic changes. Visually, most people prefer full frame windows, because they look like they were built into the original property and provide a cleaner overall look. Correctly installed, they also last longer, and they are the only way to change the size of your window should that be one of your goals.

Still, despite its advantages in enhancing structural integrity and design flexibility, full frame installation may not be the optimal choice in every scenario.

Challenges and Considerations of Full Frame Window Installations

The decision to opt for full frame window installation should be made after careful consideration of many different factors. Some of the scenarios where full frame may not be the right choice for your project includes:

• Budget Constraints – Full frame installations are typically more labor-intensive and require more materials than retrofit options, leading to higher overall costs. For homeowners working within tight budgetary constraints, this approach might be financially impractical.
• Disruption and Installation Time – Full frame installations are more invasive and time-consuming, involving the removal of interior and exterior trims and potentially affecting surrounding wall areas. This can lead to longer project timelines and greater disruption to household routines.
• Not Worth the Difference – Homes that already feature relatively recent window installations with modern framing and glass technology may see negligible energy efficiency improvements from a full frame replacement, making the investment harder to justify.
• Moving Out Soon – Full frame windows *may* add slightly more value to your property’s equity than retrofit, but it largely depends on the number of windows and the final appearance. If you have only have some windows that are not a focal point of the home, full frame is not likely to improve your property values any more than retrofit. So, if you plan to move out in the next 5 years, you may never make back the added costs.
• Don’t Want to Paint – Because full frame windows involve removing some of the exterior of your property and replacing the siding, they require additional paint. If you recently completed your paint work or you do not want to risk altering the color, you may be someone that prefers retrofit.

Though less common, in historic homes or in cases where maintaining the original architectural integrity is especially important, full frame installations might compromise the authenticity of the structure. Preservation guidelines might also restrict alterations to original window designs, or it may be too difficult to replace some of the siding and other property elements that need to be removed for full frame installation.

Alternative Window Replacement Strategies

In circumstances where full frame installations present significant drawbacks, homeowners should consider retrofit windows instead. They are less costly, and they still look amazing and can provide excellent energy efficiency improvements.

You can also mix and match. You can do full frame on windows for windows that play more of a centerpiece role in your home, and use retrofit for all the smaller windows that are less noticeable but still need replacements. Top of Form Still, you’ll often find that full frame windows are the best choice for those looking to make an upgrade, provided they are in your budget.
