What you need

Before you start thinking about replacing the pane of glass, make sure you have the tools and equipment you need to do the job properly. These include a putty knife, window putty, glazier’s points, brad nails, masking tape, heavy work gloves, replacement glass, hammer and safety goggles.

Step one

First, you need to know the measurements and safety requirements you need to be aware of. Make sure you know this information before you cut the glass or enlist the help of Emergency Glaziers in Leicester or wherever you are in the country.

Step two

Use gloves and goggles if necessary and remove the broken glass. You can use masking tape to criss-cross over a cracked pane to prevent it shattering everywhere when you tap it with a hammer to break it for removal.

Clear up the pieces and make sure that you remove everything, including the splinters, before allowing pets or children in the area. You also need to think about continuing glass safety, especially if you are running a business. Find out more about health and safety legislation at

Step three

Specialists such as can make this job really easy, but if you do find yourself doing it yourself, it is now time to clear old putty, varnish, paint and glazier points away using a putty knife. You will also need to remove the surrounding frame from a side of the glass, starting with the longer ones.

Step four

Soften a little bit of putty in your hands before spreading a thin layer on the edges of the remaining wooden frame. Next, smooth it with a putty knife.

Step five

Fix the glass in place and use your glazier points to position it exactly. Use your putty knife to push the points into place, two per side, and make sure that you have inserted them onto the frame.

Step six

Finally, reset the window strips with gentle tapping and, if needed, use brad nails.
