Windows that are exterior facing must close against weather and intrusion. The Sash Window is a vertical-slide opening design that provides good ventilation passage.
You will find that the cost to install average wood sash windows depends upon material and finish grade, size, structural preparation and special needs, and the labor rate.
In the following table the Labor Cost figure is what the able and prepared DIY persons should expect to save by performing the corresponding tasks.
