Modern Window Replacement Refreshes a 1950s Des Moines Home

Set in one of Des Moines’ established neighborhoods, this 1950s home was selected for a complete overhaul as part of the Parade of Remodeled Homes. The homeowners loved the mature trees, the walkable location and the original charm of the property—but the aging windows told another story. Drafty rooms, inconsistent temperatures and fading exterior trims made it clear the windows were long past their lifespan.

As part of a full-home renovation, the design team partnered with Pella Central Iowa to replace every window with energy-efficient fiberglass units that would elevate both performance and curb appeal. The result is a home that feels brighter, more comfortable and perfectly aligned with the clean, transitional style of the remodel.

From the street, the difference is immediate—sleek, white double-hung windows now frame the home’s refreshed exterior, complementing the painted brick and warm new landscaping. Inside, every room benefits from clearer views, smoother operation and improved energy efficiency.

The homeowners wanted windows that looked classic yet modern, an Impervia’s clean lines and subtle profiles fit the architecture without overwhelming it. Because the material is incredibly durable and stable, the frames stay true over time—an important consideration for homes built more than 70 years ago, where openings aren’t always perfectly square.

Throughout the project, a mix of operable double-hung, casement and picture windows were used to optimize natural light and airflow while keeping a consistent aesthetic from room to room.

Double-hung windows were installed in most rooms of the home, offering the familiar functionality the homeowners were used to—but with a far better user experience.

Upstairs bedrooms, the main living room and the dining area all feature new double-hung windows in various widths. These windows are designed to move smoothly, seal tightly and reduce drafts—an upgrade the homeowners immediately noticed.

The crisp white interior finish complements the new millwork, while the exterior matches seamlessly with the updated siding and brickwork.

One of the standout features of the remodel is the dramatic wall of windows overlooking the backyard. Here, three tall picture windows sit above a wide sliding patio door, creating a floor-to-ceiling effect that fills the room with natural light.

These fixed units were chosen not only for scale, but for simplicity. Their sleek profiles allow the outdoor views—lush trees, sunlight and sky—to become the focal point. Paired with the airy, double-height ceiling, this window combination transforms the main living space into a bright, welcoming centerpiece of the home.

At the front of the home, a new 3-wide double-hung square bay window redefines the façade. The bay extends slightly outward, adding architectural interest while drawing more daylight into the interior.

Inside, the bay creates a comfortable nook with expanded lines of sight and a connection to the front yard. Outside, the clean grid pattern and balanced proportions enhance the home’s classic style, making it a highlight for Parade visitors and passersby alike.

In areas where airflow and ease of operation were priorities—such as the bathrooms and secondary bedrooms—the team selected casement windows. These units open wide to bring in fresh air and provide excellent ventilation.

The simple hardware and slim frame design keep the look consistent with the rest of the home, ensuring that the mix of window styles feels thoughtful and cohesive rather than pieced together.

One of the most unique features of the remodel is the bifold pass through window installed in the kitchen entertaining area. This wide, outswing unit folds completely open, connecting the indoors and outdoors in a way that’s perfect for hosting.

Whether passing food out to the patio or opening the space on a beautiful Iowa evening, the bifold brings flexibility and fun to everyday living—all while maintaining the clean, modern look of the rest of the windows.

Because the 1952 home had original or decades-old windows in many openings, the energy savings from the upgrade were immediately noticeable. Fiberglass frames paired with advanced Low-E insulated glass help regulate indoor temperatures, reduce heat transfer and limit UV exposure.

For the homeowners, that means fewer drafts, quieter rooms and more consistent comfort year-round—especially during Iowa’s cold winters and humid summers.

This whole-home window replacement didn’t just update the look of the property—it changed the way the family uses and enjoys their space. Natural light now fills rooms that were once dim. Fresh air flows more easily. And the exterior has a balanced, timeless appearance that aligns beautifully with the remodel’s transitional design.

With the help of Pella Central Iowa, the homeowners were able to combine modern performance with classic curb appeal, creating a home that feels both refreshed and rooted in its original character.
