A cracked or shattered window is more than an eyesore—it’s a safety hazard and an energy drain. Whether you’re dealing with a single cracked pane or a fully broken window, broken glass window repair can be handled safely and affordably. In this guide, you’ll learn how to assess damage, gather the right tools, and choose between DIY fixes and professional replacement.

Broken Glass Window

1. Assess the Damage Quickly and Safely

Before tackling broken glass window repair, take a careful look:

  • Minor cracks or chips can often be repaired in place.
  • Spider-web cracks that spread across the pane usually mean it’s time for replacement.
  • Fully shattered glass requires immediate boarding up or taping to secure your home.

Safety first: Always wear thick gloves, long sleeves, and eye protection. Use duct tape or masking tape on both sides of a cracked pane to contain fragments while you plan the repair.

2. Know When to DIY vs. Call a Pro

DIY Repairs

  • Best for single-pane windows with small chips or hairline cracks.
  • You can apply a clear epoxy or resin repair kit to fill and stabilize the crack.
  • Ideal when you’re on a budget and comfortable with basic tools.

Professional Replacement

  • Necessary for double- or triple-pane insulated windows, tempered safety glass, or historic frames.
  • Pros handle glass removal, precise measurements, custom glazing, and secure installation—critical for energy efficiency and airtight seals.
  • Worth the investment if you value guaranteed weatherproof performance and warranty protection.

3. Gather Materials for DIY Glass Repair

If you decide on a quick DIY fix for minor damage, you’ll need:

  • Clear window repair resin or epoxy kit
  • Stiff scraper or razor blade
  • Soft cloth and glass cleaner
  • Painter’s tape to mask around the crack
  • UV light (for resin kits that cure with sunlight or a UV lamp)

4. Step-by-Step DIY Crack Repair

  1. Clean the glass surface with a lint-free cloth and glass cleaner—remove dirt and oils.
  2. Mask the area around the crack with painter’s tape to protect the frame and glass.
  3. Apply the resin following kit instructions—inject it directly into the crack.
  4. Cure the resin under UV light or direct sunlight, as specified (usually 10–15 minutes).
  5. Scrape off excess resin with a razor blade, then buff the surface smooth.

This process can restore clarity and strength to minor cracks, buying you time until a full replacement.

5. Steps for Full Pane Replacement

For extensive damage or insulated units, follow these guidelines—or best, hire a professional:

  1. Measure carefully: Record the height, width, and glass thickness.
  2. Remove old glazing: Use a putty knife to scrape away old putty or glazing beads.
  3. Extract broken glass: Wrap shards in heavy-duty paper or cloth, and dispose of safely.
  4. Prep the frame: Clean, prime, and apply a fresh bead of glazing compound.
  5. Install new glass: Press gently into the compound, secure with glazing clips or points if needed.
  6. Seal and finish: Apply exterior-grade sealant or new glazing compound, then paint or touch up trim.

6. Cost Considerations for Broken Glass Window Repair

  • DIY resin kits: $10–$25 per pane, ideal for small cracks.
  • Professional crack repair: $50–$100, depending on travel and service fees.
  • Full pane replacement: $150–$500 for single-pane windows; $300–$1,000+ for insulated units or specialty glass.

Always get at least two quotes for replacement work—prices vary by material, window size, and local labor rates.

7. Prevent Future Breakage and Maintain Your Windows

  • Install window film or storm shutters in high-wind or high-impact areas.
  • Keep trees trimmed away from windows to reduce branch strikes in storms.
  • Inspect and re-caulk annually to maintain tight seals and prevent water intrusion.
  • Use tempered or laminated glass where safety and durability are essential.

Routine maintenance extends window life and can save on costly broken glass window repair down the road.
