Bay Window vs. Bow Window Cost in Baltimore, MD

What You Are Really Paying For

Bay and bow windows are often grouped together, yet the price depends on how each one is framed, supported, and finished inside and out.

A bow window uses four, five, or even more narrower panels to create a softer curve.

As a working range, many Baltimore homeowners see bay windows priced around $4,000 to $10,000 installed, with bow windows often ranging from $5,000 to $12,000, especially when the project includes carpentry, siding, drywall, or load-bearing changes.

The final price also changes based on whether the window is being replaced in an existing opening or added where no bump-out exists yet.

• Material choice
• Headers, framing, and support work can add a meaningful amount to the job

• Historic or permit requirements

That is especially true for places like Fells Point, Federal Hill, Mount Vernon, and Roland Park, where older construction and stricter aesthetics often shape the decision as much as budget does.
