When individuals speak about double glazing leakages, they usually indicate one of two things:
- Water Leaks: Water is getting in the home from the exterior due to jeopardized outside seals, flashing, or drain issues.

|---|---|---|
| Failed Edge Seal | The main adhesive bonding the glass to the spacer bar breaks down due to age or UV direct exposure. | Condensation caught in between the glass panes. |
| Abject Weatherstripping | Rubber or foam gaskets around the opening sash flatten, crack, or diminish in time. | Drafts and water entering throughout heavy rainstorms. |
| Obstructed Drainage Weep Holes | Dirt, particles, or insect nests clog the external drainage channels developed into the window frame. | Water overflows the inner track and swimming pools on the windowsill. |
| Faulty Flashing/ Silicone | The exterior sealant or flashing connecting the window frame to the brickwork has degraded. | Moist spots on the interior walls surrounding to the window. |

- Using Exterior Caulk: If the gap is between the outer frame and the wall, using a fresh bead of exterior-grade silicone sealant can fix the problem.
When You Need a Professional:
- Failed Sealed Units (IGUs): Once wetness gets caught inside the double glazing system, a DIY fix is practically difficult. While some companies provide defogging services (drilling holes to dry the inside), this is normally a momentary repair.

- Bead Removal: The internal or external glazing beads holding the glass pane in place are popped out using a specialized putty knife.
- Unit Replacement: If handling internal condensation, the old glass unit is removed, and a brand-new, gas-filled Insulated Glass Unit (IGU) is fitted with fresh setting blocks.
