Window Repair vs. Replacement: Which Is Cheaper?

Windows fail in different ways - a broken seal, a rotted frame, a cracked pane, hardware that won't latch. Whether you repair or replace depends on what failed, the window's age, and your budget. Here's how to decide and what it costs either way.

Window Repair Costs

Broken glass (single pane): $100-$250 per pane Broken glass (double pane): $200-$500 per pane Failed seal (foggy glass, double pane): $100-$250 for sash replacement or $75-$200 for reglazing Rotted wood frame repair: $150-$400 per window Balancer or spring replacement (double-hung): $75-$200 Latch or lock hardware: $50-$150 Weatherstripping: $50-$150 per window

For most repair scenarios, a window contractor can fix the issue for $100-$400. The question is whether the repair gets you another 10-15 years out of the window or just delays the inevitable.

Window Replacement Costs

Single window replacement (standard size, vinyl): $350-$700 installed Large or non-standard window: $700-$1,500 installed Full home window replacement (20 windows): $8,000-$20,000

These are installed prices. The window itself is $150-$400 for standard sizes; installation labor adds $150-$250 per window for a straightforward replacement in kind.

When to Repair

Isolated problem: One broken pane, one bad lock, one rotted section of frame. If the rest of the window is in good shape and the window itself is under 15-20 years old, repair is usually the right call.

Budget constraints: Repair costs a fraction of replacement. If you need to prioritize spending, repair the failing windows now and plan replacements in future years.

Historic or custom windows: If your windows are original to an older home or have custom dimensions, replacement windows are expensive and may not match the original style. Skilled window restoration is worth pursuing.

When to Replace

Failed double-pane seal: Foggy glass that won't clear is a failed seal between the panes. Technically repairable (sash replacement or reglazing), but if multiple windows are showing this, the windows are at end of life. Replacement makes more sense.

Significant frame rot: Rotted wood frames that are structural (not just surface rot) can't be repaired to a satisfactory state. Replacement is the only durable fix.

Energy efficiency: Single-pane windows are a major source of heating and cooling loss. If your home has original single-pane windows, replacement pays back in energy savings over time - especially in California where summers are hot.

Windows are 20-25+ years old: Most vinyl windows last 20-25 years. Wood windows can last longer with maintenance. If your windows are near end of life and starting to have issues, replacement is more cost-effective than repeated repairs.

The Energy Efficiency Calculation

In California, window replacement qualifies for: - Utility rebates through PG&E, SCE, SoCalGas (varies by program) - Potential federal tax credit (check current IRA provisions)

Energy-efficient windows (ENERGY STAR rated) can reduce heating and cooling costs by 12-25% in a home with old windows. In California's climate, the payback period is typically 10-15 years.

How to Get a Good Price on Either

For repair: Contact a local window contractor or a handyman who specializes in windows. Get the specific problem diagnosed before agreeing to anything.

For replacement: Get three quotes minimum. Ask for the specific brand, model, and U-factor of the window being installed. Big differences in price often come down to window quality, not just labor.

Avoid door-to-door window salespeople. They are almost universally overpriced and use high-pressure tactics. Licensed contractors who are busy with referral business don't need to knock on doors.

Bottom Line

Window repair costs $100-$400 for most issues. Window replacement costs $350-$700 per window installed. Repair is the right choice for isolated issues on newer windows. Replace when windows are at end of life, have structural frame problems, or are single-pane in a California climate.
