Replacement vs New Construction Windows in Millbrae: What’s Best for Your Home Renovation?

When planning a remodel or upgrade in Millbrae, one common question homeowners face is whether to choose replacement windows or new construction windows. While both options improve comfort, energy efficiency, and appearance, the right choice depends on your home’s condition, scope of work, and renovation goals.

Replacement Windows: Ideal for Existing Homes

Replacement windows are designed to fit into an existing window opening without removing the surrounding frame or exterior finishes. This makes them a popular option for replacement windows for existing homes.

Why homeowners choose replacement windows:

  • Faster and less invasive window installation

  • Minimal disruption to interior and exterior finishes

  • More affordable overall replacement windows cost and installation

  • Ideal for homes where window frames are still in good condition

Things to consider:

  • Limited flexibility if existing frames are damaged or out of square

  • Slightly smaller glass area compared to new construction windows

Best for: Homeowners upgrading windows as part of a refresh, energy-efficiency upgrade, or light remodel.

New Construction Windows: Best for Full Remodels & Structural Changes

New construction windows are installed directly into the wall framing and include a nailing flange, making them ideal when walls are open.

Why homeowners choose new construction windows:

  • Best option when framing is exposed

  • Allows for resizing or repositioning windows

  • Full integration with new siding, stucco, or exterior finishes

  • Ideal for major remodels and additions

Things to consider:

  • Higher labor and installation costs

  • Requires removal of exterior materials

  • More time-intensive installation

Best for: Full home remodels, additions, or projects involving exterior wall reconstruction.
