When the system works as intended, it traps air and avoids heat transfer. When the seal stops working, outside wetness gets in the space, and the insulating gas gets away, rendering the window far less effective.

• Drafts Around the Frame: If cold air is seeping in around the edges of the window even when it is safely shut, the window gaskets or seals have degraded.

• The residential or commercial property requires a total aesthetic overhaul (e.g., changing from out-of-date aluminum to contemporary uPVC or lumber).

Common Double Glazed Window Repairs and What They Involve

Specialist window specialists manage a variety of problems daily. Below are the most regular repairs performed on double-glazed windows:

3. Resealing and Re-gasketing

Rubber gaskets shrink and crack in time, letting in drafts and wetness. Specialists can strip out the old, fragile gaskets and insert fresh rubber seals around the sash and frame, dramatically improving thermal efficiency.

4. Frame Realignment (Toe and Heel)

If a window drops and captures on the frame when closing, it generally requires to be “toe and heeled.” This is a technique where the glass is rearranged inside the frame using plastic packers to square it up and bring back smooth operation.
