What Is a Deglazing Tool?

A deglazing tool is a must-have tool for removing windows. The specially designed blades are there to cut through old sealant with ease, for easy bead removal to remove your windows. 

The tool is sharp and features heat-treated blades to cut through even the toughest of sealants, such as strong sealant on double-glazed window units. This will create an effortless cut in window seals for the quick removal of windows.

This tool is essential for professional glaziers’ tool kits, whilst other must-haves and essential tools include a glazing hammer, glass cutter, suction cups, silicone sealant and gasket rollers.

Although widely used in the glazing industry, deglazing tools are not just for professional use - they can be used by anyone who needs them to replace an old or broken window.

Deglazing tools can be used on windows and pretty much anything else that has a sealant finish and the sealant needs to be cut, removed and replaced.

How to Replace a Window

Now that you have an understanding and all the information on the top deglazing tools around, you can now get to work at deglazing your window to fit your new one. To learn more, just keep reading.


Step One - Have Your Equipment Ready

Make sure you have all the necessary tools and equipment you need before starting window replacement. This includes your chosen sealant, deglazing tool, glazing tool, gasket roller, sealant finisher, etc. whatever your preferred tools to use are.

You will want to lay an old sheet or something similar on the floor whilst you work. Glazing work can be a messy job - old glaze, dust and other debris including glass are likely to fall on the floor and make a mess. Having a sheet down will save you a lot of time and effort cleaning up later on, as it can catch any fallout.

Make sure you are wearing all the necessary personal protective equipment that you need to keep you safe. Safety comes first whenever you are completing a job. The items of safety gear that you will need to wear will include; safety goggles, and thick gloves which can be necessary to protect your hands from glass breakage and shards. Also, make sure you have closed-toe shoes or safety boots if you are handling large and heavy glass.


Step Two - Removal of the Window

You will need to take out the sash by pulling it carefully out of the frame. Use your putty knife or deglazing tool to take the sealant out.

This will be easy if the sealant is old, but you may need to apply some pressure if it is still intact. Be careful with your tool as you do not want to harm the frame or break the glass.


Step Three - Replace the Glass

Place a few beads of glaze inside the frame of the glass. This is what the new glass will adhere to. Gently place the glass into the frame over your glazing beads and press firmly so that it sticks to the frame.

Do not worry at this stage about the sealant being messy, as you can simply cut off the excess with a putty knife after it hardens.


Step Four - Seal the Glass

Cover the edges of the glass with a thick layer of sealant, and make sure you leave no gaps or hollow spots. Keep it even all the way around.

Use a sealant finisher to press the sealant down and make it smooth, you should use one continuous movement along the sealant to ensure a professional finish. You can cut off any excess to make it look neat too.
