How to Safely Do a Broken Window Temporary Repair
Stephen Griswell • April 7, 2026
So, a window broke. After you’ve safely swept up the last of the glass shards, you’re left staring at an empty frame. Now what? You need to cover that opening, and you need to do it fast. The good news is that you don’t need to be a professional contractor to create a solid temporary fix. Many of the materials required for a broken window temporary repair might already be in your garage or are easily found at a local hardware store. From heavy-duty plastic sheeting to a sturdy piece of plywood, we’ll show you which materials work best and how to install them correctly to keep your home sealed and secure.
Key Takeaways
- Make safety your first step: Before you do anything else, clear the area of children and pets. Always put on protective gear like thick gloves and sturdy, closed-toe shoes to handle broken glass without getting hurt.
- Secure the opening immediately: After cleaning up the glass, cover the hole with materials you have on hand, such as heavy plastic, a tarp, or plywood. Use strong tape to create a tight seal that protects your home from weather and pests.
- Understand a temporary fix isn't permanent: A patch is a great short-term solution, but a professional repair is necessary for your home's long-term security and energy efficiency. Calling an expert prevents future problems like drafts, high energy bills, or water damage.
First Steps After a Window Breaks
The sound of shattering glass is jarring, and it can leave you feeling flustered and unsure of what to do next. Whether it was a stray baseball or a storm, a broken window exposes your home to the elements and compromises your security. Taking a deep breath and following a few immediate steps can make all the difference. Before you even think about a temporary fix, your focus should be on making the area safe, assessing the situation, and securing the opening. These first actions will help you manage the situation calmly and effectively until you can get a permanent repair.
Prioritize Safety
Before you do anything else, make safety your top priority. Broken glass is incredibly sharp and can cause serious injuries. The first thing you should do is clear the area, making sure children and pets are kept far away from the hazard. Don't try to handle the glass with your bare hands. Find a pair of thick work gloves, like leather or heavy-duty rubber gloves, and put on a pair of sturdy, closed-toe shoes to protect your feet from any stray shards on the floor. If you have safety glasses, now is the time to wear them to prevent tiny glass particles from getting into your eyes.
Check the Damage
Once you have your safety gear on, you can begin to carefully clean up the mess and see what you’re dealing with. Start by picking up the largest pieces of glass and placing them in a thick paper bag or a doubled-up plastic bag to prevent them from tearing through. For the smaller slivers and dust, use a broom and dustpan to sweep them up. To be extra thorough, you can use a vacuum cleaner with a hose attachment to get the tiniest particles out of carpets or corners. Just be sure to empty the vacuum canister or bag carefully afterward. This process helps you safely clear the area and get a better look at the window frame itself.
Secure Your Home
With the immediate danger of broken glass removed, your next goal is to cover the opening. A broken window leaves your home vulnerable to weather, pests, and potential intruders. Creating a temporary barrier is a crucial step to keep your home secure and prevent your heating or air conditioning from escaping. This is just a short-term solution to hold you over until you can schedule a professional window replacement. Materials like heavy-duty plastic sheeting, a tarp, or even a piece of plywood can be used to seal the opening for now. This temporary cover will give you peace of mind while you arrange for a permanent fix.
How to Safely Clean Up Broken Glass
Before you can even think about a temporary fix, you need to deal with the mess. Cleaning up broken glass isn't like sweeping up crumbs; it requires a careful, methodical approach to make sure you get every last shard and keep everyone in your home safe. Taking a few extra minutes to clean up properly can prevent painful cuts and lingering hazards. Let's walk through how to handle this safely, step by step.
Get Your Safety Gear
First things first: protect yourself. Never handle broken glass with your bare hands. Before you pick up a single piece, you need to put safety first by gearing up. Find a pair of thick, puncture-resistant gloves, like leather work gloves or heavy-duty rubber gloves. You’ll also want to wear closed-toe shoes to protect your feet from any stray shards on the floor. If you have safety glasses, put them on. This might feel like overkill, but tiny pieces of glass can easily fly up during cleanup, and protecting your eyes is always a smart move.
Remove the Broken Glass
With your gear on, you can start the cleanup. Begin by carefully picking up the largest pieces of glass and placing them on a thick layer of newspaper or into a designated cardboard box. If there are still jagged pieces stuck in the window frame, place an old towel or cloth on the floor directly beneath them. Then, using a hammer, gently tap the glass from the inside to loosen it and let it fall safely onto the cloth. Once the big pieces are gone, it’s time to tackle the tiny, almost invisible slivers. The best way to get rid of tiny glass shards is with a vacuum cleaner using a hose attachment. Go over the area thoroughly, including baseboards and any nearby furniture.
Dispose of the Glass Correctly
Proper disposal is just as important as the cleanup itself. You can’t just toss broken glass into your regular trash bag, where it could easily slice through and injure someone. Carefully wrap the larger pieces in several layers of newspaper before placing them in the box. Once all the glass is collected, including the contents of your vacuum cleaner, seal the box securely with packing tape. For an extra layer of safety, you can place the wrapped glass in a heavy-duty paper bag or a double-layered plastic bag before putting it in the box. Finally, use a thick marker to clearly label the box "Broken Glass." This simple step helps protect your local sanitation workers from accidental injury.
Best Materials for a Temporary Window Fix
Once the area is clean, your next step is to cover the opening to protect your home from weather and pests. You don’t need to be a pro to create a solid temporary patch. Many of these materials might already be in your garage or are easy to find at a local hardware store. Your choice will depend on the size of the break and what you have on hand.
Plastic Sheeting and Tarps
For a quick cover, heavy-duty plastic sheeting or a tarp is your best bet. Even a thick trash bag can work in a pinch. The goal is to create a barrier against wind and rain, so I recommend doubling up the plastic for a stronger, more insulated layer. Cut the material so it’s larger than the window opening, then secure it tightly to the frame with duct tape or a staple gun. This creates a solid seal to keep cold air and moisture out until you can arrange for a proper home repair.
Cardboard and Plywood
For a shattered pane or when you need more security, cardboard or plywood are excellent options. Plywood is the sturdiest choice, offering a rigid barrier that helps protect your home. Carefully measure the window opening and cut the material to fit snugly inside the frame. This helps hold it in place and provides better insulation than plastic alone. You can secure it further by taping the edges to the frame. This sturdy fix offers great peace of mind while you schedule a professional window replacement.
Strong Tapes and Adhesives
If you’re just dealing with a crack, you don’t need to cover the whole window. Strong adhesives like clear packing tape or duct tape are a simple fix. First, make sure the glass is completely clean and dry so the adhesive sticks properly. Apply the tape firmly over the entire length of the crack on both the inside and outside of the window. This creates a seal that prevents drafts and moisture from getting in, and it also helps stabilize the glass to keep the crack from spreading.
Nail Polish for Minor Cracks
It might sound unusual, but for tiny cracks or small chips, clear nail polish is a surprisingly handy tool. It works by filling the minuscule gap and creating a waterproof seal. Start with a clean, dry surface, then carefully apply a thin layer of clear nail polish directly into the crack. Let it dry completely before adding another one or two layers to build up a durable seal. This clever trick can stop a small crack in its tracks and keep it from becoming a bigger problem while you wait for a permanent solution.
How to Temporarily Seal Your Broken Window
Once you’ve cleaned up the glass, your next priority is to seal the opening. A temporary fix protects your home from weather, pests, and potential intruders until you can schedule a professional repair. The method you choose will depend on the size of the break and the materials you have on hand. Remember, these solutions are not permanent; they are meant to secure your home for a short period. After you’ve put a temporary patch in place, it’s important to contact a professional to assess the damage and discuss a permanent solution, like a full window replacement. A proper repair is essential for your home's long-term security, insulation, and value.
Cover the Window from the Inside
For a simple crack where the glass is still intact, a quick seal from the inside works well. Start by thoroughly cleaning the area around the crack to remove any dust or moisture. This ensures the tape can adhere properly. Once the surface is dry, apply clear packing tape or heavy-duty masking tape firmly over the entire length of the crack. Press down to smooth out any air bubbles. This simple step can prevent the crack from spreading, keep drafts out, and hold the glass together until you can get it professionally fixed. It’s a straightforward, immediate action you can take to manage the situation.
Protect the Window from the Outside
If the glass is completely shattered or there’s a large hole, you’ll need a more substantial barrier. Covering the window from the outside with plywood or thick cardboard offers a robust temporary shield. Measure the window opening carefully and cut the material so it fits snugly within the frame. A tight fit is key to providing the best protection against the elements and adding a layer of security. You can secure the board in place with screws or heavy-duty tape. This method effectively blocks wind and rain while also deterring anyone from trying to enter through the broken pane.
Create a Double-Layer Seal
For superior insulation and protection, especially if you’re expecting harsh weather, a double-layer seal is an excellent option. This approach combines an exterior and interior barrier. Start by fitting a piece of plywood to the outside of the window opening. Then, from the inside, place a piece of foam board insulation into the opening. Finally, cover the interior side with a sheet of heavy plastic, taping it securely to the window frame. This "sandwich" method creates a much more effective barrier against temperature changes and moisture, helping to keep your home comfortable while you wait for a permanent repair.
Seal Against the Weather
When your main concern is blocking out cold air and moisture, heavy plastic sheeting is a reliable choice. A strong, double-layered trash bag can work in a pinch. Measure and cut the plastic so it’s slightly larger than the window opening. Fold it over for extra durability, then staple or tape it securely to the window frame. Make sure the seal is as airtight as possible to prevent drafts. This is a great temporary fix during colder months, helping you maintain indoor temperatures and prevent moisture from damaging your home's exterior.
Know When to Call a Professional
A temporary patch on a broken window is a great short-term solution, but it’s not meant to last forever. Knowing the right time to switch from a DIY fix to a professional repair is crucial for your home’s safety, security, and energy efficiency. While you can handle the immediate cleanup and covering, a permanent fix almost always requires an expert. If you’re unsure whether your situation warrants a call, there are a few clear signs that it’s time to hand the job over to a professional team. Paying attention to these indicators can save you from bigger headaches like water damage, high energy bills, and security vulnerabilities down the road.
Signs Your Temporary Fix Is Failing
Your temporary patch is designed to get you through an emergency, but it will show signs of wear. If you notice the tape peeling away, the plastic sheeting flapping in the wind, or hear a whistling sound, it means your seal is no longer airtight. A draft is a sure sign that your fix isn't keeping the elements out, which can lead to higher heating or cooling costs. Moisture seeping in around the edges or condensation building up behind your patch are also red flags. These issues indicate that your temporary solution can no longer protect your home from water damage and it’s time for a permanent, professional window replacement.
Safety Risks That Need an Expert
Your safety should always come first. While cleaning up glass from the floor is one thing, dealing with shards still stuck in the window frame is a different story. This is where the risk of serious injury increases. If the broken window is on an upper floor or is a large, heavy pane of glass, attempting a repair yourself can be dangerous. Professionals have the right equipment, like ladders, heavy-duty gloves, and specialized tools, to remove stubborn glass and install a new window safely. Don’t risk a fall or a deep cut; if the job feels even slightly beyond your comfort zone, it’s best to contact an expert.
Long-Term Energy and Security Concerns
A broken window, even one that’s temporarily covered, can create lasting problems. A boarded-up window can make your home a target for intruders by signaling a vulnerability. Beyond security, a patched window is a major source of energy loss. Even the best temporary fix can’t match the insulating properties of a properly sealed, double-paned window. Over time, this air leakage will show up on your energy bills. Furthermore, if you notice fog or condensation between the panes of your other windows, it’s a sign of a broken seal, which also compromises your home’s energy efficiency. A professional can address these issues to restore your home’s security and comfort.

Frequently Asked Questions
What's the most important first step after my window breaks? Before you even think about cleanup, your first priority is safety. Immediately clear the area of any children or pets to prevent accidents. Then, before you handle any glass, find a pair of thick gloves and put on sturdy, closed-toe shoes to protect yourself from sharp fragments.
Can I just leave a temporary patch on my window indefinitely? A temporary fix is only meant to be a short-term solution. Materials like plastic and tape will break down over time when exposed to sun and rain, leading to drafts, water leaks, and poor energy efficiency. It's best to view a temporary patch as a bridge to getting a permanent, professional repair.
What should I do if the window frame itself is also damaged? If the frame is cracked, warped, or broken, this complicates the repair significantly. A damaged frame can compromise the seal and stability of a new window pane. This is a clear sign that you need to call a professional who can assess the full extent of the damage and determine if a simple replacement or a more involved repair is necessary.
Is it safe to repair a broken window on an upper floor myself? Working on windows above the ground floor presents serious safety risks. Handling heavy glass while on a ladder is dangerous and requires specific equipment and experience. For any window that isn't easily and safely accessible from the ground, I strongly recommend calling an expert to handle the job correctly and without risk of injury.
My window only has a small crack. Do I still need to do something about it? Yes, even a small crack shouldn't be ignored. Temperature fluctuations and vibrations from simply opening and closing a door can cause a small crack to spread across the entire pane. You can use a temporary fix like clear tape to stabilize it, but you should still plan for a professional repair to prevent it from becoming a much bigger issue.
