How to Install New Glasses to your Window Panes

Windows serve many purposes; their utilitarian purposes being providing privacy from the outside and security from potential robbers. Additionally, even though it is not apparent, windows also serve insulation purposes and adding to the overall appearance of our home both from the outside and inside.

If you are in the process of building your new window, repairing a broken one, or changing the glasses to make it more beautiful, here is a guide on how to install new glasses to your window panes.

  • Linseed Oil
  • Glazing Solution
  • Putty Knife

  • Paint

  • Wire Brush
  • Glazier’s Point

Step 1. Remove the Old Glass 

     Before installing our new set of glasses, we first have to remove the old pieces. To remove the glass, we must remove the putty that is holding it. Use a putty knife to scrape off all of the putty, be careful when almost all of the putty is gone because the glass may fall off unexpectedly. If there are stubborn putty that clings to the window frames, soften them by heating them through blowers.  

     If the old glass is broken, use working gloves to pick off the remaining broken glass that still clings to the window pane. Swipe off broken shards of glasses in the floor so you and other members of your family would avoid cuts. To be completely safe, you can contact professionals like replacement windows Bolton 

     Step 2. Glazing 

     After removing the old glass now is the time to clean and glaze the old window frame. Use a wire brush to remove dust and other sediments that have clung into the corners of your window panes. You can also clean it by using a wet and clean cloth. 

     After cleaning, apply the linseed oil to the windowpane; this oil helps the glazing solution to set more deeply into the wood. Apply the Glazing Solution with uniform strokes into the window pane; this would create consistency, which will make the window pane look better and new. 

     Step 3. Measuring and Preparing 

     After glazing the window pane, now is the time to measure its dimensions. Make sure that you are accurate on measuring the spaces, so you won’t waste money or energy into cutting the glasses to fit your window pane.  

     When you have your new glass, you then have to prepare the window panes by putting small amounts of putty into it. Make sure you won’t apply more than necessary putty because they can bulge out and smudge your glass.  

     Step 4. Install and Secure 

     Now that you have small amounts of putty, you can safely install the new glasses because the putty acts as a cushion. When the glass is in place, take out your Glazier’s point and attach its point in the wood, near the glass. Glazier’s point provides stability to your glass in the window pane; in a single glass, use eight pieces, two pieces on each side near the four corners of the glass. 

     Fortify your glasses by applying putty. Prepare your putty first by kneading it to a piece of glass, knead it until there are no lumps left and the lump is not too thick or thin. Using a putty knife, apply it evenly to the sides of the glass. Finish it by applying paint into the putty; make sure that the color of the paint is the same as the window pane, or at least, complements it.
