An insert replacement window fits inside your existing window frame. Instead of removing the entire unit, we keep the original frame in place and remove the sash, hardware, and glass before installing a new window unit directly into the existing opening.
This type of replacement is often a smart option when the existing frame is still structurally sound. It is typically faster to install, less disruptive to your home, and often more cost-effective than a full frame replacement.
What Is a Full Frame Replacement Window?
A full frame replacement is a complete window replacement. That means the old window, the existing frame, and the trim are removed all the way back to the rough opening before a brand-new window system is installed.
This approach gives us the opportunity to start fresh. It also allows us to inspect the entire opening, correct hidden issues, and make sure the new window is installed into a solid, properly sealed structure.

When Do You Need a Full Frame Replacement?
If your current window frame is rotted, warped, or water damaged, an insert replacement is usually not the right solution. In many Central Indiana homes, especially homes built before the 1990s, we often find frame issues that need to be addressed before a new window can truly perform the way it should.
Installing a new window into a failing structure only hides the real problem. A full frame replacement allows those underlying issues to be corrected so your home gets the long-term durability, insulation, and performance you expect from a new window investment.
How Modern Day Window & Door Helps You Decide
At Modern Day Window & Door, we assess every window opening before recommending an insert replacement or a full frame replacement. We are not going to upsell you on a full frame installation if an insert is the right call, and we are not going to take the cheaper route if your home needs a more complete solution.
Our job is to help you make the best decision for your Indianapolis-area home based on condition, performance, and long-term value. We will walk you through exactly what we see and explain which option makes the most sense for your home.
"The right installation depends on the condition of your home, not just the price tag."

Frequently Asked Questions
Is an insert replacement window always cheaper?
In many cases, yes. Insert replacement windows are usually less expensive because the installation is less labor-intensive. However, they are only a good value when the existing frame is still in good condition.
How do I know if my window frame has damage?
Common warning signs include soft wood, visible rot, water staining, warping, drafts, or windows that no longer operate properly. A professional inspection is the best way to confirm whether the frame is still sound.
Are full frame replacement windows worth it?
Yes, when the existing frame has structural or moisture-related issues. A full frame replacement addresses the entire opening, which helps protect long-term performance, efficiency, and durability.
Which option is better for older Indianapolis homes?
If you are considering replacement windows for your home, Modern Day Window & Door can help you understand whether an insert or full frame installation is the best fit for your needs.
