Broken Home Window? Here’s What to Do Next
A broken home window is a stressful situation that demands immediate, structured action. Whether caused by an errant baseball, a severe windstorm, a fallen tree branch, or an attempted break-in, a shattered glass pane leaves your property vulnerable to weather elements, pest intrusion, and security risks. Additionally, loose glass shards present an immediate physical safety hazard to children, pets, and family members.
Knowing the exact steps to take directly after a window breaks allows you to manage the situation safely, protect your living space, and streamline the repair process. Here is a comprehensive, step-by-step guide explaining what to do from the moment the glass shatters until your permanent replacement window is safely installed.
Step 1: Secure the Area and Prioritize Personal Safety
Your immediate priority after a window breaks must be human safety. Glass shards are sharp, heavy, and unpredictable. Before you begin inspecting the damage or picking up fallen debris, take control of the immediate environment.
First, evacuate children and pets from the room where the glass broke. Keep them behind closed doors in a separate part of the house until the entire area is cleared and thoroughly cleaned. Small shards can easily embed in shoe soles or pet paws, leading to painful injuries.
Next, put on proper protective gear before approaching the broken window. Never handle broken window glass with bare hands or wear open-toed shoes. Put on thick leather work gloves, heavy-duty closed-toe shoes or work boots with thick rubber soles, and protective safety glasses. If the broken glass is still hanging precariously from the upper window sash, wearing a long-sleeved shirt and heavy denim pants protects your arms and legs from falling shards.
If the window was broken during an attempted burglary, break-in, or act of vandalism, do not touch anything or clear away debris immediately. Exit the home or retreat to a safe area and call local law enforcement right away. Wait for police officers to arrive, inspect the property, and file an official police report before you touch the window or clean up the scene.
Step 2: Carefully Clean Up Loose Glass Shards
Once the area is safe to enter and any law enforcement procedures are complete, you can begin clearing away loose glass. Cleaning up glass requires a methodical approach to ensure no microscopic slivers remain hidden in carpets, rug fibers, or floor cracks.
Start by picking up the largest pieces of glass by hand while wearing your heavy leather gloves. Place these large pieces directly into a heavy-duty plastic contractor trash bag. Standard kitchen trash bags are too thin and will puncture easily when filled with sharp glass. To prevent the glass from tearing through the contractor bag, place the plastic bag inside a sturdy cardboard box first.
After removing the large pieces, check the window frame itself. If there are loose, cracked pieces of glass still hanging loosely within the sash, gently wiggle them to see if they come free easily. If a shard resists, do not force it or yank on it, as doing so can cause the glass to crack further or drop onto your hands. Leave firmly attached shards in place for the professional glazier to remove safely during repair.
Once the bulk of the glass is removed from the floor, sweep the entire room thoroughly using a stiff-bristled broom and a dustpan. Sweep in multiple directions, extending your search radius at least ten to fifteen feet away from the window, as flying glass can travel surprisingly far upon impact.
After sweeping, vacuum the hard floor or carpet using a vacuum cleaner hose attachment. Avoid using a vacuum with a rotating brush roll on hard floors, as the spinning bristles can kick small glass slivers across the room. For fine, nearly invisible glass dust trapped on hard surface floors, press strips of wide duct tape or a damp paper towel firmly against the floor to pick up lingering micro-shards. Dispose of the paper towel or tape directly into your heavy cardboard disposal box.
Step 3: Apply a Temporary Cover to the Window Opening
After clearing away loose glass, you must seal the open window frame to restore basic home security, keep out rain and cold drafts, and prevent insects or rodents from entering your home.
The method you choose for covering the broken window depends on the severity of the damage and how long you must wait for professional repair.
Covering a Partially Cracked Glass Pane
If the window pane is still largely intact inside the frame but features a deep crack running across the glass, you can stabilize the pane temporarily using clear packing tape or heavy-duty duct tape. Apply strips of tape smoothly across the crack on both the interior and exterior sides of the glass pane. Extend the tape at least two inches past the ends of the crack on all sides. This temporary measure holds the glass together and prevents the crack from spreading while you schedule a professional repair appointment.
Covering a Completely Shattered Glass Opening
If the glass has fallen out entirely, leaving an open hole in your window frame, you need a full weather barrier. For a short-term fix lasting a day or two, use thick plastic sheeting, a heavy-duty tarp, or multiple layers of heavy contractor trash bags.
Cut the plastic sheet so that it overlaps the interior and exterior window frame by at least two to three inches on all sides. Secure the plastic tightly to the interior window frame using strong masking tape or painter tape to avoid damaging the painted wood or vinyl finish. Next, go outside and secure a second layer of plastic over the exterior frame using duct tape. The double-layer plastic barrier creates an insulating dead-air pocket that slows down drafts and keeps rain out.
If you expect bad weather, high winds, or a multi-day wait for specialized replacement glass, consider boarding up the window with exterior-grade plywood. Measure the window frame opening and cut a piece of five-eighths-inch plywood to fit flush over the frame. Anchor the plywood to the frame using wood screws. Boarding up provides superior structural strength and acts as a strong visual deterrent against potential intruders.
Step 4: Document the Damage for Insurance Purposes
Before you complete your temporary repairs or allow a contractor to remove the damaged window components, take time to thoroughly document the scene for insurance purposes.
Take high-resolution photographs and video footage of the broken window from multiple angles. Capture close-up shots of the shattered glass, the damaged window frame, and any surrounding wall or sill damage. Additionally, take wide-angle photos showing the entire room and the exterior elevation of your home to provide clear context for insurance adjusters.
If the broken window caused secondary damage to interior furnishings, carpets, artwork, or electronic equipment, document those damaged items as well. Keep a written log noting the date, time, and cause of the incident.
Check your homeowners insurance policy details to determine your coverage limits and deductible amount. Standard homeowners insurance policies typically cover window glass breakage caused by storms, hail, falling tree limbs, vandalism, or accidental impacts. However, if the cost of replacing the glass is close to or lower than your policy deductible, filing an insurance claim may not be financially practical. Obtaining an initial estimate from a professional glass contractor helps you decide whether to pay out of pocket or file an insurance claim.
Step 5: Contact a Professional Glass Service
Replacing home window glass requires specialized tools, precise measurements, and technical expertise. Modern residential windows are complex mechanical assemblies designed to deliver energy efficiency and structural stability. Attempting a DIY glass replacement without professional training often leads to improper frame seals, draft leaks, premature double-pane seal failure, and voided manufacturer warranties.
When selecting a repair contractor, choose a licensed, insured, and experienced company that specializes in residential glass replacement. Reliable glaziers will inspect your broken window, evaluate whether the glass alone can be replaced or if the entire window sash assembly requires replacement, and provide an accurate quote.
Homeowners seeking expert assistance can explore comprehensive options for professional residential glass services to restore their building envelope quickly and safely. Working with local specialists ensures your replacement window complies with state building codes and safety glazing mandates.

Step 6: Evaluate Your Window Repair and Replacement Options
When your glass technician arrives, they will evaluate the structural condition of your window assembly to recommend the best path forward. Depending on the age of your window and the extent of the damage, you will generally face two main replacement routes: Glass-Only Replacement or Full Window Unit Replacement.
Glass-Only (IGU) Replacement
If your window frame, sills, and operating sashes are in sound condition, you do not need to replace the entire window system. The technician can carefully remove the broken glass pane from the existing frame and install a new custom-fabricated Insulated Glass Unit (IGU).
Most modern home windows utilize IGUs, which consist of two panes of glass separated by an airtight spacer bar and filled with insulating argon gas. The technician measures the precise height, width, thickness, and glass type required, orders a custom replacement unit, and installs it directly into your existing frame. This option is fast, cost-effective, and preserves your interior trim and exterior siding.

Full Window Frame Replacement
If the impact that broke the glass also warped, cracked, or rotted the surrounding wood or vinyl window frame, glass-only replacement is not viable. Installing new glass into a twisted or structurally compromised frame causes edge pressure points that lead to future spontaneous glass cracking. In this scenario, a full-frame replacement is necessary.
A full-frame replacement involves removing the old frame, sills, and sashes down to the rough wall opening, inspecting for hidden water rot, and installing a completely new window assembly. While more involved, a full replacement allows you to upgrade to modern, high-efficiency window designs that lower utility costs and elevate curb appeal.
Understanding your options is easier when working alongside experienced glass technicians who can explain material differences, energy ratings, and warranty terms clearly.
Step 7: Consider Upgrading Your Replacement Glass
A broken window presents an unexpected hassle, but it also creates an opportunity to upgrade your home's energy performance, comfort, and security. Rather than installing basic single-pane or standard clear glass, discuss modern glass technologies with your installer.
Energy-Efficient Low-E Coatings
If your original window lacked energy-efficient features, upgrade your replacement glass unit to include Low-Emissivity (Low-E) coatings. Low-E coatings are microscopically thin metallic layers applied to internal glass surfaces. They reflect radiant heat, keeping solar heat out during summer and trapping furnace heat inside during winter.
Tempered or Laminated Safety Glass
If the broken window was located in a high-traffic area, near a door, or along a staircase, consider upgrading to safety glass. Tempered glass undergoes intense thermal heat treatment, making it four to five times stronger than standard float glass. If broken, it disintegrates into small, dull pebbles rather than razor-sharp shards.
Laminated glass features a clear vinyl interlayer sandwiched between two glass sheets. When struck, the glass cracks but remains firmly adhered to the plastic interlayer, providing superior protection against storms, high winds, and forced-entry attempts.

Frequently Asked Questions
How much does it cost to fix a broken home window?
The cost to fix a broken home window varies depending on the size of the window, the type of glass, and whether you are replacing just the glass unit or the entire window frame. Replacing a standard single-pane glass unit is relatively inexpensive, while custom double-pane insulated glass units with Low-E coatings or tempered safety glass cost more. If the window frame is severely damaged and requires full-frame replacement, labor and material costs will increase accordingly.
Does homeowners insurance cover broken window glass?
Yes, standard homeowners insurance policies generally cover broken window glass if the damage was caused by a covered peril, such as severe storms, hail, vandalism, or accidental impacts like a fallen tree branch. However, you must consider your policy deductible. If your deductible is five hundred dollars and the glass repair cost is four hundred dollars, paying out of pocket is more practical than filing an official insurance claim.
Can you replace just the glass in a window without replacing the frame?
Yes, in most cases you can replace just the glass pane or double-pane insulated glass unit without removing or replacing the entire window frame. As long as the surrounding frame, sills, and sashes are structurally sound, square, and free of rot or severe warping, a professional glazier can remove the broken glass unit and fit a new, custom-sized glass panel directly into the existing frame.
How do you temporarily cover a broken window safely?
To temporarily cover a broken window, start by putting on thick leather gloves and eye protection to clean up all loose glass shards safely. For small cracks, apply clear heavy-duty packing tape or duct tape across the crack on both sides of the glass. For completely shattered openings, cover the frame with two layers of heavy-duty plastic contractor trash bags or thick plastic sheeting, taping the edges securely to the interior and exterior frame. For maximum security during long delays, screw a sheet of exterior-grade plywood directly over the window opening.
Is a broken home window considered a emergency repair?
Yes, a broken home window is considered an emergency repair situation. An open or compromised window leaves your property exposed to secondary weather damage, outdoor pests, cold drafts, and security risks like burglary. Taking immediate steps to clear the glass, apply a secure temporary board-up, and contact a professional residential glass contractor ensures your home remains safe and protected while permanent replacement glass is fabricated.
