Typical Double Glazed Window Repairs and What They Involve

Expert window service technicians handle a wide array of problems daily. Below are the most frequent repairs performed on double-glazed windows:

3. Resealing and Re-gasketing

Rubber gaskets shrink and split gradually, letting in drafts and moisture. Professionals can remove out the old, fragile gaskets and insert fresh rubber seals around the sash and frame, drastically enhancing thermal effectiveness.

4. Frame Realignment (Toe and Heel)
