How to Fix Broken Double Pane Windows

Double pane windows can be fixed at home with the right tools and some patience for the details. If only one side of the glass has broken, then you can also replace just the one side, if you have aluminum windows. If you have vinyl double paned windows then you will need to replace the whole unit. Both sides of the glass will need to be replaced because of the way that the seal is applied. If you choose to only replace one side of glass on your aluminum double paned windows, you're taking more of a risk that something can go wrong.

Order the Right Size

Order the right size of glass to replace the broken one. Measure the interior of the frame and then find out how much glass is installed into the frame. It's usually about a half an inch on all sides. This means that you will need to add an inch to each side of each measurement in order to account for the framing. Make certain that your measurements are accurate, as you will need to be very specific when ordering your replacement glass.

Know the Thickness

Another important measurement is the thickness of the glass and the space in between the glass. In order to fit into the frame correctly the glass shop will install a spacer for you in between the two layers of glass. When ordering your glass, another piece of information that you will need is the color of the glass. Bronze or silver will be your choices.

Get the Frame Ready

While you're waiting for your glass, you can get the frame ready. You need to remove the outer section of the frame. There may be screws or you may need to slide the sides up or down to remove them. Remove whatever is left of the glass and the seal. Wearing gloves you can use a utility knife to cut away the seal. For metal frames you may need to use a hacksaw to get through the seal. Use the saw blade without the saw handle and use your hand to guide it along the surface of the seal.

Install the Glass

Apply a new seal to the lower edge of the frame. After this is applied, you can apply the glass and then the second seal. After the second seal is applied, place the top portion of the frame back in place. Use slight pressure in order to form a seal all around the window. Let the seal cure for 24 hours before installation. You will have a secure seal and a window that is ready to install and use the next day.

After you have done your first repair, the next will be much simpler. You can always purchase a new window, but it's easy and much more inexpensive to try and repair the window. If you do not feel comfortable installing either, there a plenty of window professionals that can do the job. If you watch how they do it then maybe next time you have an issue with your double pane windows, you will be able to do it yourself.
