Double Glazed Windows Repairs

Then, you can use the tool's ball-shaped end to break up the glass fragments, which should come off fairly quickly.

After the glass has been removed, scrape off any old glazing compound from the recess of the frame. This will expose the metal clips and glazier's pins that keep the glass in the frame. Replace them if you notice any corrosion. If the window is wooden the glazier's points could be re-used if they're still intact.

The surface of the remaining frame needs to be prepared to allow reflazing. Using a caulking gun, apply a continuous ribbon of compound along the inside edge of the recess. Use a high-quality putty such as glazier's compounds that is contained in a cartridge or a conventional compound that comes in a tin. Let it dry before inserting the glass. If the frame has metal clippings, they should be reinstalled too. Install the dividers.
