When considering whether to install new construction windows or replacement windows in an existing home, it’s important to understand the differences between the two options.

New Construction Windows

These windows are designed for installation in new construction homes or major renovation projects where the existing window frames are completely removed.

They have a nailing flange or fin that allows them to be secured directly to the house’s framing.

New construction windows require the removal of the existing window frames, siding, and trim, which can result in more extensive and costly installation work.

These windows offer greater design flexibility and customization options, allowing for a wide range of sizes, shapes, and styles.

They typically provide better energy efficiency and insulation, as they can be tightly integrated with the building envelope.

Replacement Windows

These windows are designed to fit within the existing window frames without major renovation or structural changes.

They are typically custom-built to match the dimensions of the existing window openings, ensuring a proper fit.

Replacement windows are installed by removing the old sashes and glass while retaining the existing window frame, resulting in less disruption and lower installation costs.

These windows offer a convenient and cost-effective option for upgrading existing windows’ energy efficiency, functionality, and appearance.

They may have limitations in size and design options compared to new construction windows.

Retrofitting these windows into an existing home may result in a less clean or finished appearance than replacement windows.

Cost: 

Installing new construction windows in an existing home may be more labor-intensive and costly than replacement windows, as it often involves additional construction work.
