How to Fix a Broken Window Glass

Window glass is akin to our eyes, and when damaged, it needs immediate care. A broken window looks unsightly, can be hazardous, and often requires emergency glass repair.

Some issues can be patched temporarily, while others require replacing the glass or even the entire window. This guide outlines the main options so you can choose what’s best for your situation.

Tools & Materials Needed to Replace a Broken Window

Always prepare before handling broken glass. Wear cut-proof gloves and safety goggles, clear the work area, and lay down a drop cloth to catch shards. You may need:

• Utility knife, putty knife, screwdriver, glazing putty knife.
• Tape measure, glass cutter, straightedge, pencil.
• Silicone or mounting tape, glazing points, glazing compound.
• Replacement glass cut to size.
• Optional: sandpaper, linseed oil, exterior-grade paint.

Having everything ready will make your repair safer and more efficient.

How to Temporarily Fix a Broken Windowpane

These methods stabilize cracks and stop drafts until a permanent repair is possible. Clean and dry the glass once before applying any fix.

Take the following steps as a temporary fix for a broken house window:

#1. Secure the Area

First, make the space safe. Shut the door or separate the space with a barrier, like a sheet of cardboard or a partition.

Put on sturdy shoes and gloves, then warn family members to stay clear until cleanup is finished.

#2. Clean the Surface Carefully

When cleaning up broken glass, wear protective clothing, long pants, and closed-toe shoes. Collect large pieces with thick paper or cardboard and place them in a garbage bag. Sweep up small shards with a dustpan, then vacuum the area to catch anything left.

Wash the glazed surface gently with warm soapy water and rinse clean.

#3. Dry out the Cracked Spot

Thoroughly dry the cracked area before attempting to repair it to ensure a successful repair and save time. Utilize a hair dryer or any other fan around the house to expedite drying. If any moisture is left in the crack, your repair efforts will be futile.

#4. Degrease the Place

Degreasing is necessary when repairing a cracked window because it removes any oils and dirt that may have built up on the window’s surface to ensure strong bonding.

Use acetone for best results, applied with a lint-free cloth, synthetic cotton, or medical bandage. Avoid natural cotton that can leave fibers behind.

#5. Use Temporary Window Fixes

A temporary fix for a broken house window may not be aesthetically appealing, but it can help you avoid further damage until proper repair:

• Glass adhesive: Available online or in auto stores. Follow the instructions carefully.
• Clear nail polish or super glue: Apply in thin layers, letting each dry before the next.
• Plastic brace: Tape a sturdy plastic sheet (like from a notebook cover) over the crack on both sides.
• Strong-hold tape: For deep cracks, apply heavy-duty tape on both sides to stabilize the glass.

DIY fixes may offer a quick patch, but they can’t match the precision and durability of professional work. At Apex Window Werks, our certified specialists deliver repairs that not only last but also restore the flawless look of your windows, elevating the comfort and value of your home.

DIY Aluminum Window Glass Replacement

When it comes to aluminum window replacement, it’s generally simpler to take the window out and lay it on a flat surface. This method works well for single panes in aluminum frames, but isn’t suited for large cracks or multi-pane glass.

• Remove the frame and strips: Take out the sash or frame, then pry off the vinyl strips with a flat tool. Replace strips if brittle.
• Clear out old glass: Cut away silicone and carefully remove broken pieces. Clean the frame to prepare for new glass.
• Measure and test fit: Measure the opening precisely, order glass slightly smaller, and test fit before sealing.
• Apply silicone and seal: Run silicone along the frame, press glass in place, and apply another bead around edges for a tight seal.
• Replace vinyl strips: Snap vinyl strips back securely, starting with the bottom.

DIY Vinyl Window Glass Replacement

This option is good for replacing cracked IGUs in vinyl sashes, but isn’t recommended if the frame is warped or heavily damaged. Vinyl window repair is relatively straightforward if you follow these systematic steps:

• Remove sash and strips: Take out the sash, then pry off glazing strips with a flat tool.
• Remove old glass: Cut away tape or sealer and lift the glass unit carefully.
• Clean and prep frame: Scrape away residue and apply fresh double-sided mounting tape. Replace setting blocks at corners.
• Install new glass unit: Set the glass evenly, press it against tape, and ensure it fits snugly.
• Reassemble and test: Snap glazing strips back into place, reinstall sash, and check window operation.
