Why Bay Windows Cost So Much More
Bay and bow windows involve multiple window units joined at angles, structural support for the projecting design, and often custom framing — fundamentally more complex than a standard rectangular window opening, which explains the dramatic cost jump compared to single- or double-hung styles.
Double-Hung: The Practical Default
Double-hung windows (where both the upper and lower sash can move) offer the best balance of cost, functionality, and ease of maintenance for most standard home replacements — one reason they're among the most common styles chosen nationally.
Casement and Awning Windows
Casement windows (hinged on the side, opening outward via a crank) and awning windows (hinged at the top) generally fall in a similar cost range to double-hung windows, while offering a tighter seal when closed — often a slightly better efficiency performer than sliding or double-hung styles, worth considering if energy performance is a top priority alongside style preference.
Frequently Asked Questions
Not necessarily — you can change styles during replacement, though switching to a more complex style (like adding a bay window where a standard one existed) adds structural work and cost beyond a simple like-for-like swap.
Generally comparable in cost for similar sizes — the bigger cost differences come from material and glass package choices more than the sliding-vs-double-hung distinction itself.
