Sash & Case Window Repairs

Sash and Case Window Repairs

Sash and case windows are a type of traditional window commonly found in historic buildings, particularly in regions like the UK, the US, and parts of Europe. These windows consist of a frame (the case) that holds one or more movable sashes—vertical panels that contain the glass and can slide up and down. Sash windows are known for their elegance and the way they can provide ventilation and natural light, but like any older window type, they can require repair and maintenance over time.

Before diving into the repair process, it’s important to understand the common problems that arise with sash and case windows:

• Rattling or loose sashes: Over time, the sashes can become loose due to wear on the sash cords, weights, or the frame itself, causing the window to rattle when it’s open or closed.

• Paint decay and rot: Wood is a common material used for sash windows, and over time, weather exposure can cause the wood to deteriorate, leading to rot or peeling paint.

• Sticking or hard-to-open sashes: The sashes may become stiff or difficult to move if the wood swells due to moisture or if the mechanisms (like the pulleys and cords) have worn out.

• Broken or cracked glass: The glass panes can get damaged due to accidents, weather, or aging.

• Condensation or drafts: Over time, sash windows may lose their airtight seal, leading to drafts and condensation between the panes (if it’s double-glazed), or air leakage around the frame.
