Why You Should Hire a Glazier to Repair Double Glazing Seals

Remove the Old Seal

In the case of double-glazed windows, the most typical indication that the seal has broken is the appearance of condensation between the two glass panes. This is caused when the gas that acts as an insulator such as argon or krypton that was sealed by vacuum between the two panes of glass has escaped. When this occurs, the window is no longer able to seal moisture and cold air out of the home.

Fortunately, repairing a faulty window seal is quite simple. You can purchase a replacement wedge gasket seal at any hardware store and it will be installed easily on your uPVC windows.
