Before diving into repairs, it assists to understand the anatomy of a double-glazed window. Unlike single-pane glass, a double-glazed unit (typically referred to as an Insulated Glass Unit or IGU) consists of two panes of glass separated by a spacer bar.
- The Glass: Two panes, typically 4mm thick, provide a barrier against the elements.
- The Spacer Bar: This separates the glass panes and generally consists of a desiccant (drying agent) to take in wetness.
- The Gas Fill: The space between the panes is typically filled with an inert gas, such as argon or krypton, which enhances thermal performance.
- The Seal: Primary and secondary seals hermetically bind the glass to the spacer bar, keeping the gas in and moisture out.
When any of these elements fail, the window's effectiveness drops, signifying that it is time for maintenance or repair work.

2. Drafts and Cold Spots
If one can feel air leaking around the window frame or sash, the seals, gaskets, or weatherstripping have actually most likely degraded.

Puddles or wetness on the windowsill throughout rainstorms show that external seals or flashing have failed.
5. Increased Outside Noise

- System Removal: The failed glass unit is lifted out of the frame.
- Setting Blocks: New setting blocks are placed at the bottom of the frame to support the brand-new glass equally.
- Installation: The brand-new IGU is slotted into location, and the glazing beads are tapped firmly back into position.
Repairing Faulty Hinges and Handles
With time, uPVC window mechanisms (espagnolette bolts, friction stays, and handles) wear.
- Hinges: If a window drops and fails to close flush, friction stays (hinges) can be unscrewed and changed with new ones matched to the weight and size of the window.
Handles: A broken deal with is generally held in location by 2 screws concealed underneath a cover cap. Unscrewing the old deal with and changing it with a universal or brand-matched spindle handle takes less than ten minutes.
