DIY: How to Replace Broken Glass in a Picture Frame

A shattered picture frame can be heartbreaking, especially if it holds a cherished memory. But don’t despair! Replacing the broken glass is a surprisingly simple DIY project that can save you money and restore your precious photos or artwork. This comprehensive guide will walk you through each step, from assessing the damage to safely disposing of the broken glass and installing the new pane. Let’s get started!

What You’ll Need

Before you begin, gather the following materials and tools:

• New Glass: Measure the inside dimensions of your picture frame precisely. Subtract 1/16″ to 1/8″ from both the length and width to allow for slight expansion and contraction and ensure easy fitting. It’s best to have the glass cut to size at a local hardware store or glass shop. Specify the type of glass you want (more on that below).
• Safety Glasses: Protect your eyes from flying glass shards.
• Work Gloves: Protect your hands from cuts and abrasions.
• Heavy-Duty Tape (Packing Tape or Duct Tape): To secure broken glass pieces and aid in removal.
• Putty Knife or Utility Knife: To help remove the old glass and any remaining glazing.
• Pliers (Optional): For removing stubborn brads or fasteners.
• Small Flathead Screwdriver (Optional): For prying open the frame backing if needed.
• Vacuum Cleaner with Hose Attachment: To thoroughly clean up glass fragments.
• Broom and Dustpan: For sweeping up larger pieces of glass.
• Rags or Paper Towels: For cleaning the frame and surrounding area.
• Glass Cleaner: To clean the new glass.
• Glazing Points or Flexible Tabs: To secure the glass in the frame (these are small metal or plastic pieces that hold the glass in place). You can find these at most hardware or craft stores. The type you need depends on the frame.
• Point Driver (Optional): A tool specifically designed to insert glazing points. It makes the job easier but isn’t essential.
• Measuring Tape or Ruler: For accurate measurements.
• Pencil or Marker: To mark measurements.
• Old Newspaper or Drop Cloth: To protect your work surface.
• Heavy-Duty Trash Bag or Container: For safe disposal of broken glass.

Choosing the Right Glass

The type of glass you choose will affect the appearance and protection of your picture or artwork. Here’s a rundown of common options:

• Standard Glass (Float Glass): This is the most common and affordable option. It’s clear and provides good visibility. However, it can be reflective, causing glare.
• Non-Glare Glass (Matte Glass): This glass has a frosted surface that diffuses light, reducing glare. While it’s excellent for displaying artwork in brightly lit areas, it can slightly reduce the clarity of the image.
• UV-Protective Glass: This type of glass filters out harmful ultraviolet (UV) rays that can fade and damage artwork over time. It’s ideal for valuable or irreplaceable pieces. Museum glass offers the highest level of UV protection.
• Acrylic (Plexiglass): While technically not glass, acrylic is a popular alternative. It’s lightweight, shatter-resistant, and offers good clarity. However, it can scratch more easily than glass. It also tends to accumulate static electricity which can attract dust.

For most standard picture frames, standard glass is perfectly adequate. If you’re framing valuable artwork or photos, consider UV-protective glass. If glare is a concern, non-glare glass might be the best choice. Acrylic is good for frames that will be handled frequently or are in areas where breakage is a concern (like a child’s room).

Step-by-Step Guide to Replacing Picture Frame Glass

Follow these steps carefully to safely and effectively replace the broken glass in your picture frame:

1. Prepare Your Workspace

Find a well-lit and ventilated area to work. Cover your work surface with old newspaper or a drop cloth to protect it from scratches and glass shards. Clear the area of any distractions.

2. Assess the Damage

Before you start, carefully examine the frame and the broken glass. Note how the glass was originally secured (glazing points, flexible tabs, etc.). If the frame itself is damaged, you may need to repair it before replacing the glass. Minor scratches can often be touched up with a furniture marker.

3. Safety First: Secure the Broken Glass

This is the most crucial step for your safety. Use heavy-duty tape (packing tape or duct tape) to carefully secure the broken glass pieces. Apply the tape generously, covering all the broken edges and fragments. This will help prevent the glass from shifting and causing further injury when you remove it.

4. Remove the Frame Backing

Carefully remove the backing of the picture frame. This is usually held in place by flexible tabs, small nails (brads), or a combination of both. Flexible tabs can usually be bent back with your fingers or a small flathead screwdriver. If brads are present, you can use pliers to gently pull them out from the back of the frame. Be careful not to damage the frame while removing the backing.

5. Carefully Remove the Broken Glass

Wearing your safety glasses and work gloves, carefully lift the taped broken glass out of the frame. Work slowly and deliberately to avoid dislodging any shards. If the glass is stuck, use a putty knife or utility knife to gently pry it loose from the frame. Be extremely cautious and apply even pressure to avoid breaking the glass further.

6. Clean the Frame

Once the broken glass is removed, thoroughly clean the inside of the frame. Use a vacuum cleaner with a hose attachment to remove any remaining glass fragments, dust, and debris. Pay particular attention to the corners and edges. Wipe down the frame with a damp cloth to remove any lingering dirt or grime. Let the frame dry completely before proceeding.

7. Remove Old Glazing Points (if applicable)

If the frame uses glazing points to secure the glass, you’ll need to remove the old ones. Use a putty knife, small flathead screwdriver, or pliers to carefully pry them out. Be careful not to damage the frame. If the glazing points are deeply embedded, you may need to use a bit of force. A point driver removal tool is useful if you have one.

8. Install the New Glass

Carefully slide the new glass into the frame. Make sure it fits snugly and is centered. If the glass is too tight, it could break. If it’s too loose, it won’t be properly secured. A small gap of about 1/16″ to 1/8″ around the edges is ideal to allow for expansion and contraction of the glass due to temperature and humidity changes.

9. Secure the Glass

Now it’s time to secure the new glass in place. Use new glazing points or flexible tabs, depending on the type of frame.

• Glazing Points: If using glazing points, insert them around the perimeter of the glass, spacing them evenly apart (usually every 3-4 inches). Use a point driver or putty knife to push the glazing points firmly into the frame, securing the glass. The points should be flush with the frame and hold the glass snugly.
• Flexible Tabs: If using flexible tabs, bend them over the glass to hold it in place. Ensure the tabs are snug but not too tight, as excessive pressure could crack the glass.

Make sure the glass is securely held in place and doesn’t rattle or move around.

10. Replace the Frame Backing

Carefully replace the frame backing. Secure it using the original method (flexible tabs, brads, etc.). If the original fasteners are damaged or missing, you can use new ones. Make sure the backing is flush with the frame and securely in place.

11. Clean the New Glass

Clean the new glass with a glass cleaner and a soft cloth. Remove any fingerprints, smudges, or dust. Ensure the glass is sparkling clean for optimal viewing.

12. Dispose of the Broken Glass Safely

This is a critical step. Carefully wrap the taped broken glass in several layers of newspaper or cardboard. Place it in a heavy-duty trash bag or container. Label the bag or container clearly as “Broken Glass” to prevent injury to sanitation workers. Dispose of the broken glass properly according to your local regulations. Some areas may have designated drop-off locations for broken glass.

Tips and Tricks for a Perfect Result

• Take Accurate Measurements: Accurate measurements are crucial for a proper fit. Double-check your measurements before ordering the new glass.
• Consider the Glass Thickness: Use glass that is the same thickness as the original glass. Standard picture frame glass is typically 2mm thick.
• Use a Point Driver: A point driver makes inserting glazing points much easier and safer. It’s a worthwhile investment if you frequently frame pictures.
• Protect Your Work Surface: Always protect your work surface with newspaper or a drop cloth to prevent scratches and damage.
• Work in a Well-Lit Area: Good lighting is essential for seeing small glass fragments and ensuring accurate placement of the new glass.
• Be Patient: Take your time and work carefully. Rushing the process can lead to mistakes or injuries.
• Practice Makes Perfect: If you’re new to framing, consider practicing on an old frame before working on a valuable piece.
• Inspect the Frame: Before replacing the glass, check the frame for any damage like loose joints, scratches, or dents. Repair these issues before inserting the new glass for a professional result. Use wood glue for loose joints and touch-up markers for minor blemishes.
• Consider Professional Framing: If you are uncomfortable performing this repair yourself, or if the frame is particularly valuable or delicate, consider taking it to a professional framer. They have the expertise and tools to handle the job safely and efficiently.

Troubleshooting Common Problems

• Glass is Too Tight: If the glass is too tight and won’t fit in the frame, carefully sand down the edges of the glass using fine-grit sandpaper. Be sure to wear safety glasses and a dust mask. Work slowly and evenly to avoid chipping the glass.
• Glass is Too Loose: If the glass is too loose, you can add shims (small pieces of cardboard or wood) behind the glass to make it fit more snugly. Place the shims evenly around the perimeter of the glass to ensure even pressure.
• Glazing Points Won’t Stay In: If the glazing points won’t stay in, the frame may be too hard or the points may be too soft. Try using a different type of glazing point or pre-drilling small pilot holes before inserting the points.
• Backing is Difficult to Remove: If the frame backing is difficult to remove, use a small flathead screwdriver to gently pry it open. Be careful not to damage the frame. You can also try using a heat gun to soften the adhesive holding the backing in place.
