Things to Know about Window Glass Replacement

Windows are one of the most important details in the exterior of the house, but window installation is a time consuming process, and window replacement cost is not cheap.

Not everybody knows that it is not necessarily to replace the whole window. In many cases, window frames are still in good condition, and window glass replacement cost would be much cheaper than buying and installing new windows. It is also much faster and easier to replace just the glass. In this case you don’t need to worry too much about the design since the house keeps matching its original look.

Glass replacement is required when you have  broken or cracked glass, or when you need to fix the problem of condensation in double pane or triple pane windows.

Another reason why people might want to replace the window glass is to make an upgrade for their windows without investing too much money in the project. Here are some options to consider:

  • Replacing the old glass with Low-Emissivity (Low – E) glass. It stops the UV rays, thus keeps the room cooler in summer and warmer in winter by regulating the sunlight entering the room through windows.

  • Installing a Tempered glass in your old window frames is a good idea if your concern is safety and security. It offers extra durability and strength. In case the tempered glass breaks it crumbles into small pieces (same way as car glass is made), thus can prevent injury; tempered glass is often required by code.
  • Laminated glass is good solution for those who want to reduce the noise from outside. It is also considered to be more durable and has extra strength against breakage.
  • You can improve the functionality and/or the look of your windows by installing a Decorative window glass. As a low cost option you can use a decorative window film on a regular window glass. It looks just great and adds personality and charm to the whole interior.

Here are some steps you need to be aware of if you decide to replace the window glass on your own:

  1. Put on protective gloves and carefully remove the broken glass from the window frame. You can use a heat gun to soften the old glazing compound.
  2. Precisely measure the window frame. You need to order the glass just a little bit smaller than the frame. Subtract from 1/16 to 1/8 inch each way. Order glass from the store. Also, buy the push points in the hardware store small triangles that hold the glass in the window frame.
  3. Use the glazing compound to seal the new window glass. With glass scraper remove the excess of glazing compound from your new window glass.
  4. Paint the frame from the outside and use at least two coats of paint. Then clean the glass and let the window dry for 3-4 days.
