Broken Panes

One of the most common issues a double-glazed window face is broken glass. Double-pane windows are harder to break than single panes, yet accidents can happen. You should repair damaged glass as quickly as you can.

This can be a lengthy procedure and requires several tools to complete the task. You’ll need latex glazing putty, metal glazing points, pliers, a heatgun and a putty blade.

This will stop any wood or paint that is removed that is left in the sash from sticking to your tool. Also, if you do end up removing some of the sash’s wood ensure that you employ a chisel, or a utility knife instead of a chemical stripper, as this can cause damage.

This can be a gruelling problem, but it can be solved with a few easy steps.

To resolve the issue you must first remove the handle. This is easy enough using the aid of a screwdriver. Once the handle is removed, you’ll be in a position to see the screws that hold the lock to the frame. Once the screws are removed, you can employ pliers or a wrench to try and grab the bolts for the shoot.
