Your Go-To Glass Replacement Guide: What You Need to Know First


Before you grab your tools, let’s get the basics down. Window glass replacement isn’t just about swapping out broken glass. It’s about safety, precision, and a little bit of patience. Here’s what you’ll need:


  • Safety gear: Gloves, safety goggles, and a dust mask. Glass shards are no joke!

  • Tools: Putty knife, utility knife, screwdriver, glazing points, glazing putty or silicone sealant, measuring tape, and a replacement glass pane.

  • Materials: Replacement glass cut to size (measure twice, order once!), glazing compound or silicone, and painter’s tape.


Pro tip: Measure your window opening carefully. Measure the height and width in three places each (top, middle, bottom for width; left, center, right for height). Use the smallest measurement to order your glass. This ensures a perfect fit without forcing the glass into place.

Step 1: Remove the Broken Glass Safely


First things first - safety! Put on your gloves and goggles. Carefully remove any loose shards from the window frame. Use a putty knife or utility knife to scrape away old glazing putty or silicone around the edges. If the glass is shattered, cover it with painter’s tape to keep pieces from falling out.


Once the old glass is out, clean the frame thoroughly. Remove all debris, old putty, and glazing points. A clean frame means your new glass will sit snug and secure.


Step 2: Prepare the Frame for the New Glass


Now that the frame is clean, it’s time to prep it for the new pane. Apply a thin layer of fresh glazing putty or silicone sealant around the edge of the frame where the glass will sit. This acts as a cushion and seal to keep your window airtight and weatherproof.


Place the new glass pane carefully into the frame. Press it gently but firmly into the putty or sealant. Use glazing points to hold the glass in place—these tiny metal clips push into the frame and keep the glass from shifting.


Smooth out the glazing putty around the edges with your putty knife. This not only seals the glass but also gives your window a polished, finished look.

How much does it cost to replace a piece of window glass?


Wondering about the price tag? The cost to replace a piece of window glass varies depending on several factors:


  • Size of the glass pane: Larger panes cost more.

  • Type of glass: Tempered, laminated, or double-pane glass can increase the price.

  • Labor costs: If you hire a pro, expect to pay for their time and expertise.

  • Location: Prices can vary by region and availability.


On average, expect to pay between $100 and $400 for a single pane replacement, including materials and labor. DIY enthusiasts can save money by doing the work themselves, but remember to factor in the cost of tools and safety gear.


Step 3: Finishing Touches and Cleanup


Almost there! After the glazing putty has dried (usually a few days), you can paint over it to match your window frame. This step not only improves appearance but also protects the putty from weather damage.


Clean your new glass with a streak-free window cleaner and a microfiber cloth. Step back and admire your handiwork—crystal clear and looking brand new!
