Step 1: Immediate Safety -- Protect People First
Before you worry about covering the window, protect everyone in the area. Broken glass creates invisible hazards -- tiny shards embed in carpet, scatter across hard floors, and cling to clothing and shoes. Your first priority is preventing injuries.
Immediate Actions (First 2 Minutes)
Keep children and pets completely out of the room until cleanup is finished
Put on closed-toe shoes before entering the area -- glass shards are nearly invisible on hard floors
If anyone has cuts, address first aid before cleanup -- even small glass cuts can bleed significantly
Turn off any HVAC system blowing air toward the broken window to prevent scattering tiny fragments
If the Break Was a Break-In Attempt
If you suspect the window was broken intentionally, do not enter the room. Call 911 first. Wait until police clear the home before beginning any cleanup or temporary repair. Document the damage with photos before touching anything -- your insurance company and police report will need this documentation.
Step 2: Safe Glass Cleanup
Glass cleanup requires the right approach. Sweeping and vacuuming alone will not get all the fragments. Here is how professionals handle glass cleanup, and how you can do it safely at home.
What You Need
Heavy leather gloves or cut-resistant work gloves
Standard rubber dishwashing gloves are not thick enough. You need gloves rated for cut protection. Thick leather work gloves from any hardware store will work.
Safety glasses or goggles
Glass fragments can flick upward during cleanup. Eye protection is not optional -- a glass splinter in the eye is an emergency room visit.
Stiff broom and dustpan
Sweep large fragments first. Work from the outside edges of the debris field inward to avoid stepping on glass you have not seen yet.
Damp paper towels or bread slices
After sweeping, press damp paper towels across the floor to pick up micro-fragments that the broom missed. A slice of white bread works surprisingly well for this -- the soft texture grabs tiny shards. Dispose of the bread or paper towels immediately.
Heavy paper bag or cardboard box for disposal
Never put broken glass in a thin plastic trash bag. The shards will puncture it and create a hazard for anyone handling the trash. Use a heavy paper bag, a cardboard box, or double-bag with thick contractor bags. Label the container "BROKEN GLASS" for the safety of anyone who handles it later.
Removing Loose Glass from the Frame
If glass pieces are hanging loosely in the frame, carefully remove them while wearing gloves and eye protection. Gently wiggle each piece free -- do not pull hard on pieces that are stuck. If a large section of glass is still held in the frame under tension, leave it alone. Stressed glass can snap unpredictably and cause serious lacerations. A professional glazier has the tools and technique to remove glass under tension safely.
Step 3: Temporary Sealing Methods
Once the loose glass is removed and the area is cleaned up, you need to seal the opening. The right method depends on how much glass is missing and what materials you have on hand. Here are the options, ranked from quickest to most durable.
Clear Packing Tape Over Cracked Glass
Hours to a few daysBest for: Glass is cracked but still in the frame
Apply overlapping strips of clear packing tape across the entire cracked area, extending at least two inches past the cracks in every direction. Cover both sides of the glass if accessible. This holds the cracked glass together and prevents fragments from falling out. It also maintains some visibility and light transmission. This is a true temporary fix -- it prevents further deterioration but the glass still needs professional replacement.
Heavy-Duty Plastic Sheeting
1 to 3 daysBest for: Glass is partially or fully missing, mild weather
Cut a piece of thick plastic sheeting (6-mil contractor plastic is ideal, but a heavy-duty garbage bag works) at least four inches larger than the opening on all sides. Tape it securely to the interior window frame using packing tape or duct tape. Pull the plastic taut to minimize flapping in the wind. For added security, tape a second layer on the exterior if you can safely access it.
Cardboard Panel
Hours (not waterproof)Best for: Glass is fully missing, no plastic available
Cut a piece of sturdy cardboard (a flattened moving box is ideal) to fit inside the window frame. Tape it in place from the inside with duct tape. Cardboard is not waterproof, so this is best for dry weather or as a very short-term measure. Layer two pieces for added rigidity. This blocks more wind than plastic sheeting but eliminates all light.
Plywood Board-Up
Days to weeksBest for: Ground-floor security concern or severe weather expected
Cut a piece of plywood (3/8-inch or thicker) to cover the entire window opening plus two inches on each side. Screw it directly into the exterior window frame or surrounding siding using wood screws every six inches around the perimeter. This is the most secure temporary option and will withstand wind, rain, and forced entry attempts. Use this method for ground-floor windows when security is a concern.
What NOT to Do with a Broken Window
In the rush to fix a broken window, people often make mistakes that create bigger problems or safety hazards. Avoid these common errors.
Do Not Use Masking Tape on Glass
Masking tape and painter's tape do not have enough adhesive strength to hold glass fragments or secure a covering. The tape will peel off within hours, especially in cold or humid conditions. Use packing tape or duct tape only.
Do Not Push On Stuck Glass Pieces
Large glass pieces held in the frame by putty or glazing compound can be under significant stress. Pushing or pulling on them can cause them to snap suddenly and unpredictably. Leave firmly embedded glass for a professional.
Do Not Vacuum Without Sweeping First
Large glass fragments can puncture vacuum hoses, damage the motor, or jam the mechanism. Sweep up all visible pieces first, then vacuum to catch micro-fragments. Use a shop vacuum if you have one -- household vacuums are not designed for glass.
Do Not Ignore a "Small" Crack
A crack in glass will almost always grow over time due to temperature changes, wind pressure, and vibration. What starts as a small crack can become a sudden full break, especially during temperature swings common in DMV winters. Have cracked glass assessed and replaced promptly.
Do Not Leave the Broken Window Overnight Without Cover
An uncovered window opening invites rain, insects, wildlife, and potential intruders. Even in mild weather, the open hole is a security vulnerability. Always cover the opening before nightfall, even if the temporary fix is imperfect.
Do Not Attempt to Cut Replacement Glass Yourself
Cutting glass requires a proper glass cutter, a perfectly flat surface, and experience with scoring and snapping technique. An amateur cut will be uneven, may shatter the glass entirely, and can cause serious injury. Let a professional handle the replacement.
Securing a Broken Window Overnight
If the break happens in the evening and professional service is not available until morning, you need to secure the window for the night. Here is a comprehensive overnight plan that addresses weather, security, and comfort.
Weather Seal
Apply plastic sheeting on the interior and tape every edge completely. For double-pane windows where one pane is still intact, the remaining pane provides some weather protection, but you should still cover the broken side to prevent drafts and moisture infiltration into the sealed unit.
Security Layer
For ground-floor windows, add a rigid barrier (plywood or a cut-to-fit piece of heavy furniture like a bookshelf back panel) on the interior behind the plastic. A determined intruder can push through plastic sheeting in seconds. The rigid barrier provides resistance and noise if someone tries to enter.
Noise Alert
Place something that will make noise if disturbed in front of the window -- a stack of aluminum cans, a wind chime hung from the frame, or simply close and lock the interior door to the room. If you have a home security system, ensure the sensor for that window is in alarm mode, not bypass.
Temperature Management
Close the door to the room with the broken window and stuff a towel under the door gap. This isolates the cold zone from the rest of your home and prevents your heating system from running overtime trying to heat a room with an open window. Adjust your thermostat if needed.
Morning Plan
Call Expert Glass Repair at (703) 679-7741 first thing in the morning. We offer same-day service for broken windows across the DMV. Have your window measurements ready (height and width of the glass, not the frame) and note whether it is single-pane or double-pane, as this helps us bring the right replacement glass on the first visit.
When to Skip the Temporary Fix and Call Emergency Glass Service
A temporary fix is appropriate for most residential broken windows when professional service is not immediately available. However, some situations require emergency professional service right away. Do not attempt a temporary fix in these scenarios.
Large Sliding Glass Door or Picture Window
These panels are heavy, often tempered, and the openings are too large to secure effectively with plastic and tape. A large unsecured opening is a major security and weather vulnerability. Professional board-up service with plywood is needed.
Glass Door That Cannot Be Locked
If a glass door is broken in a way that prevents it from closing or locking, your home is not secure. This is a true emergency that requires immediate professional response, not a temporary patch.
Storm Damage with More Severe Weather Expected
If a storm broke the window and the forecast shows more high winds or heavy rain coming, a temporary plastic or cardboard cover will not survive. You need professional plywood board-up service before the next round of weather arrives.
Commercial Property During Business Hours
A broken storefront or office window creates liability, security, and professional appearance issues that must be addressed immediately. Businesses cannot operate normally with a broken window covered in plastic sheeting.
Break-In with Ongoing Security Concern
If the window was broken in a burglary or attempted burglary, temporary measures are not adequate for security. After police clear the scene, call for emergency board-up and plan for permanent replacement with security glass.

Frequently Asked Questions
Can I leave a broken window uncovered overnight?
You should not leave a broken window completely uncovered overnight. An open window creates security, weather, and pest entry risks. At minimum, tape heavy-duty plastic sheeting or a flattened cardboard box over the opening from the inside. For ground-floor windows, add a rigid barrier like plywood on the exterior for security.
What is the fastest way to temporarily cover a broken window?
The fastest option is a heavy-duty garbage bag or plastic sheeting taped over the opening from the inside using packing tape or duct tape. Clean the frame of any glass fragments first so the tape adheres properly. This takes about five minutes and keeps out wind and rain until a professional can install replacement glass.
Is it safe to remove broken glass from a window frame myself?
Small loose shards can be carefully removed while wearing thick leather or cut-resistant gloves and safety glasses. However, if large pieces are still held in the frame under tension, do not try to pull them out -- they can snap unpredictably and cause serious cuts. Leave firmly embedded pieces for a professional glazier.
Should I use packing tape or duct tape on a broken window?
Clear packing tape is best for taping directly over cracked glass because it holds fragments in place and lets light through. Duct tape is better for securing plastic sheeting or cardboard over an open hole because it has stronger adhesion to irregular surfaces. Avoid masking tape or painter's tape -- they do not have enough holding strength.
When should I call emergency glass repair instead of doing a temporary fix?
Call emergency glass repair immediately if the broken window is a ground-floor entry point (security risk), if it is a large sliding glass door or picture window, if a storm broke it and more severe weather is coming, if anyone in the home has mobility issues that prevent safe cleanup, or if the window is in a commercial building that must remain operational.
