How Much Does It Cost to Replace a Window Sash?

If you have older windows in your home, there may come a time when you need to replace the window sashes. The sash is the operating part of the window that holds the glass panes and allows the window to open and close. Over time, sashes can become worn down, drafty, or difficult to operate. Replacing the sashes rather than the entire window can be a more cost-effective solution in many cases.

Sash Replacement Costs


The average cost to replace a single window sash runs between $200-$500 for labor and materials. For a standard double-hung window with two sashes, it costs around $400-$1,000. Prices can vary significantly based on window size, materials used, your geographic location, and the contractor hired.


Window Sash Material Options


One of the biggest factors in replacement window sash costs is the material you choose. Here are some of the most common options and their typical price ranges:


Vinyl Sashes


Vinyl is one of the most affordable sash materials, with replacement vinyl sashes typically ranging from $100-$300 each. Vinyl requires little maintenance and won't rot, crack or peel. However, it does expand and contract more than other materials and has a shorter lifespan.


Wood Sashes


Wood sashes have a classic look and can be painted or stained. They cost around $300-$700 per sash for quality woods like pine, fir, or oak. Wood is durable but requires more maintenance with repainting/refinishing every 5-10 years. Wood-clad sashes with vinyl exteriors are also an option for $400-$800 each.


Aluminum Sashes


Aluminum sashes run $300-$600 per sash. These are very strong, corrosion-resistant, and have a neat, minimalist look. However, they can get hot in direct sunlight and have low insulating value.


Fiberglass Sashes


Increasingly popular, fiberglass sashes cost $400-$800 each. Fiberglass is extremely durable, low-maintenance, and energy efficient. However, it is more expensive than vinyl or aluminum.


Composite Sashes


Some window manufacturers offer composite sashes made from resins, wood fibers, etc. These can cost $500-$900 per sash but provide good insulation and require minimal maintenance.


The make and model of your existing windows will also impact costs. Replacing sashes in builder-grade windows with stock sashes is usually cheaper than custom sashes for architectural or specialty windows.

Labor Costs


In addition to the sash materials, you also need to factor in labor costs for professional installation. Window sash replacement is generally best left to experienced contractors rather than DIY, as it requires precise measurements, proper sealing, possible adjustment of window jambs, and more.


Typical labor rates for sash replacement are:

  • $100-$300 per window for basic sash installation
  • $200-$600 per window for sash replacement requiring jamb modification
  • $50-$200 per window for painting/staining new wood sashes

So for two double-hung windows, the total labor cost could range from $400 up to $1,600 or more if significant modifications are needed.


Additional Factors


There are a few other potential costs and considerations with sash replacement:

  • Permits may be required, adding $50-$500 to the project.
  • Old sash removal, repair of water damage, and disposal fees could add costs.
  • Replacing just the sashes rather than full windows limits energy efficiency gains.
  • New sashes likely won't exactly match the existing frame and trim.


Overall, replacing window sashes is usually cheaper than full window replacement up front, but has tradeoffs in terms of energy savings, aesthetics, and long-term costs if the remaining components wear out faster.


Whether sash replacement makes sense depends on your window conditions, budget, and goals. Getting multiple quotes from local window contractors is recommended to get a precise cost estimate for your particular project.
