If you're a Chicagoland homeowner researching window replacement, the first question on your mind is probably: how much will it cost? The answer depends on several factors, but here's a straightforward breakdown based on our 20+ years of installing windows across DuPage, Cook, Kane, Will, and Kendall counties.
Average Window Replacement Costs in 2026
For the western suburbs of Chicago, most homeowners invest between $400 and $1,200 per window, fully installed. A whole-house project (10-15 windows) typically ranges from $5,000 to $15,000. Here's what drives the price:
Window type matters most. Double-hung windows are the most affordable at $400-$700 installed. Casement windows run $500-$900. Bay and bow windows are the premium option at $1,500-$3,500 per unit. Picture windows fall in the middle at $400-$800.
Glass technology affects cost and savings. Double-pane with Low-E coating is standard and adequate for Illinois winters. Triple-pane with dual Low-E and argon gas fills costs 15-25% more but delivers 30-40% better insulation. For Chicagoland's extreme temperature swings, triple-pane pays for itself in energy savings within 5-7 years.
Frame material creates the biggest price spread. Vinyl frames are the most popular in our area at $400-$800 per window. Fiberglass (like Andersen's Fibrex composite) runs $600-$1,000 but offers superior strength and durability. Wood frames are premium at $800-$1,200+ and require ongoing maintenance.
What's Included in Our Window Replacement Price?
When we quote a window replacement project, everything is included: the window itself, professional installation by our specialized window crew (not a general handyman), removal and disposal of old windows, interior and exterior trim, insulation around the frame, and thorough cleanup. We also include a manufacturer warranty on the product and our own workmanship guarantee.
How to Save on Window Replacement
Replace multiple windows at once — the per-window cost drops significantly when we're doing a whole house versus one or two windows. Ask about 0% APR financing for qualified homeowners.
