What Is An Andersen Window Sash Replacement?

A window sash is the framed part of a window that holds the glass and fits inside the window frame. Andersen window sash replacement involves swapping out the moveable or fixed sections of your Andersen window for new ones, retaining the outer frame. This option is often cheaper and less disruptive than full window replacement and can help maintain efficiency and appearance.

Casement Sash Replacement

Casement sashes, which swing outward by crank, cost slightly more due to the hardware and design complexity. Expect to pay $200 to $450 per sash (material only), with higher costs for triple-pane or specialty glass.

Bay And Bow Window Sash Replacement

Bay and bow windows comprise multiple joined sashes. Replacement for these units ranges from $300 to $600 or more per sash. Shape, size, and configuration significantly affect final pricing.

Specialty, Custom, Or Historical Sash Replacement

Custom or specialty sashes—including those for older or architectural-series Andersen windows—start at $350 and can exceed $800 for complex designs or rare glass types.

Breakdown Of Labor Costs For Andersen Sash Replacement

Labor for sash replacement varies, largely depending on the complexity of the window and local market rates:

  • Straightforward Sash Swap: $125 to $200 per sash

Sash Replacement Full Window Replacement
Cost $275 – $1,000/sash $600 – $1,600/window
Installation Time 1–2 hours 4–8 hours
Disruption Minimal Significant (may affect interior/exterior)
Energy Efficiency Improved with new sash/glass Maximum efficiency potential
Appearance Matches existing frame Opportunity to update entire window look

Are Andersen Window Sash Replacements Covered By Warranty?

Andersen offers warranties ranging from 10 years for glass to 20 years for Fibrex composite components. If your issue is due to a manufacturing defect and within the warranty period, you may only be responsible for labor. Always check your warranty status with Andersen or the installer before ordering new sashes.

How To Obtain A Replacement Andersen Sash

  1. Visit the Andersen online parts store or consult your local Andersen dealer.
  2. Identify your exact window model and measurements, often found on the window’s data plate or etched into the glass.
  3. Request a quote based on your window size, type, and options (glass, finish, grille style).
  4. Place your order online or through a local authorized vendor.
  5. Install yourself or schedule a professional installation for guaranteed fit and function.

Prompt identification and ordering ensure you can minimize gaps in your home’s insulation and security.

DIY Andersen Sash Replacement: Is It Worth It?

For skilled homeowners, DIY sash replacement can save $125 to $400 in labor costs per window. However, accurate measurement and attention to finishing details are critical to ensure a weather-tight fit. Mistakes can lead to water leaks, drafts, and additional repair expenses. Most home improvement stores and Andersen itself provide comprehensive guides or support for installers.

Cost To Replace Multiple Andersen Window Sashes

If you need to replace multiple sashes, some retailers and contractors offer discounted rates. Ordering 5 or more sashes can reduce the per-unit cost by 5–15%, and professional installers may also reduce labor charges for bulk jobs. Always request a written estimate for multi-sash replacement projects to confirm total costs and any possible savings.

Additional Cost Considerations

  • Specialty Glass Upgrades: Obscure, tempered, or tinted glass adds $50 to $200 per sash.
  • Colors And Grilles: Custom frame finishes or decorative grilles increase material price.
  • Historic-Era Replication: Matching old or architectural windows may require custom orders, pushing costs to the higher end of the range.
  • Emergency Replacement: Expedited shipping or weekend service surcharges can apply.

Factor in all related expenses when budgeting for Andersen window sash replacement to avoid surprises down the line.

Signs You Need To Replace Your Andersen Window Sash

If you notice any of the following, sash replacement may be the best solution:

  • Visible rot, warping, or cracks in the sash frame
  • Broken, foggy, or failed glass panes
  • Difficulty opening, closing, or locking the window
  • Persistent drafts around the sash edges

Sash replacement restores the function and insulation of your Andersen windows without the extensive work and cost of replacing the entire unit.

Energy Efficiency And Cost Savings

Newer Andersen sashes often include Low-E glass options, argon fills, and better build quality, helping to lower household energy bills. Comparing energy costs before and after installation can give additional justification for the investment, especially in older homes with single-pane windows.

Frequently Asked Questions About Andersen Window Sash Replacement Cost

  • Can I upgrade glass when replacing my sash? Yes, you can opt for upgraded glass, including double/triple-pane, Low-E, or sound control glass, which may increase cost but provides improved performance.
  • Should I replace just the sash or the whole window? If the window frame is sound and looks good, sash replacement is cost-effective. For severe rot, water damage, or major updates, full replacement may be necessary.
  • How long does the replacement take? Professional replacement usually takes 1–2 hours per window, while DIY can take longer, especially for first-timers.

Tips For Reducing Andersen Sash Replacement Costs

  • Order in bulk if replacing several sashes; discounts may be applied.
  • Compare quotes from multiple contractors before committing.
  • Check your warranty to see if you qualify for free or discounted parts.
  • Consider DIY for simpler window types if you’re confident in your skills.
  • Choose standard glass and finishes when possible to avoid custom charges.

Proper planning and product selection can yield the best results for both your pocketbook and your home’s comfort.
