How much does it cost to replace a window sash?

When you find that your window is not functioning as it should, you might wonder if it’s the window sash that needs replacing. Given that a window sash plays an essential role in the overall functionality of a window, its replacement is a crucial undertaking. But how much will it cost you? Here we take an in-depth look at the factors that influence the cost, along with a comprehensive cost breakdown to help you make an informed decision.

Factors Influencing the Cost of Window Sash Replacement

Several factors can make the cost of replacing a window sash fluctuate. Here are a few more details to help you get a clearer picture:

Type of Window

Different windows come with different types of sashes. Double-hung windows typically have sashes that are more intricate to replace, leading to a higher cost. On the flip side, a single-hung window sash might be a bit less expensive to swap out.


The material from which the sash is made can significantly impact the cost. Wood is often seen as a premium option, and thus it usually has a higher cost. Aluminium, while durable, is often less expensive than wood but more costly than vinyl.

Labour Costs

The complexity of the task at hand can significantly influence the labour cost. If the job requires a meticulous touch and more time, expect labour costs to go up.

Additional Components

Your sash might not be the only thing in need of replacement. Hardware elements like locks, lifts, or even additional elements like insect screens can add extra costs to the overall project.
