Some windows age gracefully. Others reach a point where no amount of upkeep is going to bring them back. For this Yardley, PA homeowner, their existing wood bay window had hit that wall — and the decision to replace it opened the door to one of the more dramatic before-and-after transformations we've completed recently.
The original window was a classic wood bay, and you can see from the before photo exactly what years of age does to that material. Dark, heavy framing. Worn components. A look that felt dated against the rest of the home. What replaced it was an Andersen 400 Series bay window — and the difference is hard to miss.
The Project (Before & After)
The Problem: A Wood Bay Window Past Its Prime
Wood bay windows can be beautiful — there's no question about that. But they come with a maintenance burden that compounds over time. The frames need to be refinished periodically to prevent moisture intrusion, warping, and deterioration. When that upkeep slips, or when a window simply reaches the end of its natural lifespan, the signs become hard to ignore.
For this Yardley homeowner, the existing bay window had reached that point. The dark wood framing had aged significantly, the overall appearance felt heavy and outdated, and the window was no longer performing the way a bay window should — pulling in natural light, offering clean sightlines to the backyard, and contributing to the home's overall feel. It was time for a full replacement with a product built to last.
Why the Andersen 400 Series?
When it comes to bay windows, product selection matters more than people realize. A bay window isn't a single unit — it's a combination of window types assembled together, which means the quality of every component affects how the whole thing performs and looks.
The Andersen 400 Series is one of the most trusted and widely specified window lines in the industry, and for good reason. It strikes the right balance between performance, appearance, and long-term durability — and as an Andersen Certified Elite Contractor, ACRE installs 400 Series windows regularly across New Jersey, Pennsylvania, and Northern Delaware.
For this project specifically, the configuration was:
- (2) Andersen 400 Series Casement Windows — flanking both sides of the bay, casement windows provide excellent ventilation and a clean, unobstructed view when opened. The 400 Series casement operates smoothly and seals tightly when closed, providing strong energy performance.
- (1) Andersen 400 Series Picture Window — anchoring the center of the bay, the picture window is fixed and maximizes the view and natural light coming into the room. There are no moving parts, which means no gaps for air infiltration and a consistently clean look.
Together, the three-window configuration creates a classic bay layout — a large, bright focal point that opens up the room, brings in significantly more natural light than the window it replaced, and does it all with a crisp white finish that feels light and modern compared to the dark wood frame that came out.
The colonial grille pattern carried through all three windows ties the unit together and gives it a traditional, well-finished look that suits the home's architecture.
The Installation
Bay window replacement is one of the more involved window installation jobs — there's more to coordinate than a standard flat window swap, and getting the fit, seal, and alignment right across a three-window unit requires experience and attention to detail. Here's how our crew approached it:
Removal of the Existing Window: The first step was carefully removing the aging wood bay window in its entirety. Older wood bay windows can present surprises during removal — deteriorated framing, moisture damage, or compromised seals around the projection. Our crew assessed the opening thoroughly before moving forward.
Opening Preparation: Before any new window goes in, the opening has to be properly prepared. This means ensuring the frame is clean, level, and structurally sound. On a bay window, this step is especially important because the unit projects outward and relies on the surrounding structure for support. Skipping or rushing this step is one of the most common reasons bay windows underperform after installation.
Installation of the Andersen 400 Series Bay Unit: With the opening ready, our team installed the full three-window bay unit — the two flanking casement windows and the center picture window — as one cohesive assembly. Alignment, fit, and seal were checked at every stage. A bay window that isn't perfectly level or properly sealed will show it over time through drafts, condensation, and operational issues.
Sealing and Finishing: Once the unit was set, every edge was sealed to prevent air and moisture infiltration. The interior and exterior trim were finished cleanly, and both casement windows were tested for smooth operation before we wrapped up.
From inside the home, the transformation is striking. The before photo shows a dark, enclosed feel — the heavy wood framing pulling the eye inward and the room feeling smaller than it is. The after photo tells a completely different story. The white Andersen frames open the space up, the view to the backyard is clear and unobstructed, and the room feels noticeably brighter and larger.
The Result
The homeowner now has a bay window that earns its place in the room. More natural light. A cleaner, more updated look. Better energy performance. And a product — from one of the most recognized names in windows — that's built to hold up without the ongoing maintenance burden that came with the original wood frame.
This is a great example of why bay window replacement, done right, is one of the more impactful upgrades a homeowner can make. The change isn't subtle. It transforms how the room looks and feels on a daily basis.
