  Installing or repairing double glazing might seem like a task that can only be done by professionals. However, if you have the time and can purchase the right equipment, you might be able to do the job yourself. Hiring a glazer can be expensive and it is almost certainly cheaper to purchase your own glazing tools.
  
  

Hacking Knife

• A hacking knife is necessary for removing old putty from around the window frame. Whether you are installing double or single glazing, it is important to remove old putty so that the next frame and pane will fit and adhere properly. The knife is shaped like a large chisel and is most effective when you use it with a hammer.
  
  

Putty Knife

• A putty knife is the opposite of a hacking knife and is useful for spreading the putty evenly around the new window frame. Ensuring the frame is sealed protects the room from any drafts and ensures the glass is held firmly in place. You can purchase putty knives with stiff or flexible blades, depending on which type you think you'll find easiest to work with.
  
  

Dust Sheets

• Dust sheets are an important accessory for most home improvement projects. They help protect furniture, carpets and other textiles from being damaged by the work you are doing. Glazing can be a messy business and dust sheets will make the clean-up afterward much easier.
  
  

Glass Lifter

• A glass lifter is useful for lifting panes of glass into and out of the frame. This part of the glazing process can be tricky and it is often impossible to grip the edge of the glass where it meets the frame in order to safely remove or install it. Glass lifters consist of two suction pads joined together by a raised handle. Once the suction pads are attached to the glass, you can use the handle to remove it or place it into the frame.
  
  

Glazing Shovel

• A glazing shovel is another tool that is useful for fitting glass windows. With a glazing shovel you can lift and position glass panes into their frame. This spatula-like tool can help you lever panes and is especially useful when you are dealing with sunken windows. Glazing shovels are made out of plastic and you can purchase them in a variety of colors.
  
  

Skeleton Gun

• Skeleton guns are used for sealing new windows in place. They are small metal frames you can use with cylindrical putty tubes that have a retractable base. Skeleton guns are useful for applying putty evenly and it is quicker and easier to disperse putty using this method than by hand.
