If you have a damaged window, you may be wondering if it’s possible to repair the glass or if you’ll need to replace it altogether. The good news is that repair is relatively easy to do, and there are a few different methods you can use. Below, we’ll share some tips for repairing glass and how to know when it’s time to call a professional.

Inspect the damage.


Some factors that should be considered when inspecting damage include size, location, and type of damage. For example, if a window is cracked but still intact, a homeowner might be able to fix it with a piece of duct tape or some other household adhesive. If the window is completely shattered, however, it will likely need to be replaced altogether. In that case, it’s important to call a professional experienced in glass replacement and repair. Look online for a reputable technician in your area—if you live in Ottawa, for instance, search for “glass repair Ottawa” to find skilled technicians near you.

The location of the glass damage is also important. If a chip or crack is on the edge of the glass, it can often be repaired by using a special adhesive or sealant. If it’s in the middle of the pane, however, it will likely need to be fixed by replacing or reattaching the entire piece of glass.

Type of damage is another key consideration. Chips and cracks can generally be fixed with adhesives or sealants, whereas larger holes will usually require replacement glass.

By taking all these factors into account, homeowners can select an appropriate repair method for their specific situation.

Prepare your damaged glass for repair.

The supplies you will need for repairing glass depends on the type of damage that has been done. If the glass is cracked, you will need a piece of adhesive tape, some window cleaner, and a tube of silicone sealant. If the glass is broken, you will also need a screwdriver and some wire. If the glass is shattered, you will need to purchase new glass and have it replaced by a professional.

It’s important to first clean the area around the damaged glass with mild soap and water. Be sure to avoid using harsh chemicals or abrasives, as they may damage the glass further. If there is any debris or dirt on the area around the damaged glass, be sure to remove it before repairing the glass.

Follow these tips to repair the damaged glass.


The first step in repairing the glass is to apply some adhesive to the break. You can use any type of adhesive that you want, but make sure that it is compatible with the type of glass that you are using. Next, you will need to place a piece of tape over the break. Make sure that the tape covers the entire break and that there are no gaps between the pieces of tape. Once you have done this, you can then start to press down on the tape so that the adhesive will stick to it.

Once you have pressed down on the adhesive, let it dry for at least 24 hours before removing the tape. If you remove the tape too soon, the adhesive may not hold and the glass may break again. When you are ready to remove the tape, slowly peel it off the markings on the mirror or windowpane. If any of the adhesive has come off on the glass, simply apply more and press down again until it sticks firmly into place.

To insert and smooth replacement glass into an opening, begin by cleaning the area around the opening with a glass cleaner and paper towel. Next, use a utility knife to score around the edge of the opening. This will help the new glass adhere to the old glass. Apply a thin layer of adhesive to the back of the replacement glass and press it into place. Use a putty knife or credit card to smooth out any air bubbles or wrinkles in the replacement glass. Allow the adhesive to dry completely before using the window.
