How Do I Safely Board Up a Broken Window?
A broken window is more than just an eyesore; it’s a security risk and an invitation for more damage. Dealing with a broken window can feel overwhelming, but knowing how to board it up safely can give you peace of mind until a permanent repair can be made. We’ve found that taking a few simple steps can make a big difference in protecting your home.
Why Boarding Up is Important
When a window breaks, your home is exposed. Boarding it up acts as a temporary shield. It keeps out intruders, preventing theft and vandalism. It also stops weather elements like rain and wind from entering your home. This is especially important to prevent further damage, such as the kind that can lead to water intrusion from storm damage.
Immediate Safety Concerns
Before you even think about grabbing materials, your safety is the top priority. Broken glass is sharp and dangerous. Always wear thick gloves and eye protection. Sweep up any loose shards of glass immediately. If the break is extensive, consider calling a professional to assess the situation before you attempt any DIY fixes.
Gathering Your Materials
You’ll need a few key items to get the job done right. Think of it like preparing for a small construction project. Having everything ready makes the process much smoother and safer. You don’t want to be searching for a tool with a gaping hole in your wall.
Essential Tools and Supplies
For a sturdy temporary fix, you’ll need:
- A sturdy piece of plywood (3/4 inch thick is recommended).
- A saw to cut the plywood.
- A drill and screws (at least 2-3 inches long).
- A tape measure.
- A hammer and nails (optional, screws are more secure).
- Safety glasses and heavy-duty gloves.
- A utility knife (for any stubborn glass fragments).
The plywood should be large enough to cover the entire window opening, plus an extra inch or two on all sides. This overlap ensures a secure fit and better protection. We found that using exterior-grade plywood is best for durability.
Step-by-Step: Boarding Up Your Window
Now that you have your supplies, let’s get to work. Remember to move slowly and deliberately. Rushing can lead to accidents. This process is designed to be straightforward, even if you’re not a seasoned DIYer.
Measuring and Cutting the Plywood
Carefully measure the dimensions of the window opening. Measure the width and height. Add about two inches to each measurement. This extra bit allows the plywood to overlap the window frame or the wall studs. This overlap is key for a secure and weather-tight seal.
Transfer these measurements to your plywood sheet. Use a straight edge to draw your cutting lines. Cut the plywood to size using your saw. If you don’t have a saw, many hardware stores can cut the wood for you if you provide the measurements.
Cutting for Interior vs. Exterior Boarding
You have two main options for where to place the board. You can attach it from the inside or the outside. Boarding from the outside offers better security and weather protection. It also prevents further damage to your interior finishes. However, if the exterior is inaccessible or unsafe, boarding from the inside is a viable alternative.
If boarding from the inside, ensure the plywood is cut to fit snugly within the window frame. If boarding from the outside, the plywood should cover the entire frame and extend onto the wall. This provides a more robust barrier. We recommend boarding from the outside whenever possible to prevent further structural damage.
Attaching the Plywood Securely
This is where you make the opening secure. You want the plywood to be firmly attached so it won’t budge. This is critical for both security and preventing further issues, like preventing rainwater coming through the ceiling.
Securing from the Outside
Position the cut plywood over the window opening on the exterior. Ensure it’s centered and the overlap is even. Use your drill to drive screws through the plywood and into the window frame or, ideally, the wall studs. Space screws every 6-8 inches around the perimeter. This ensures the board is held tightly in place.
If you can’t hit studs, use longer screws that go deep into the framing. This provides the strongest hold. This method is very effective at preventing further weather damage.
Securing from the Inside
If you must board from the inside, place the plywood against the interior frame. Drill screws through the plywood into the window frame. If the frame is weak, try to screw into the wall studs surrounding the window. This method is less secure than exterior boarding but can still offer temporary protection. It’s important to note that improper boarding can lead to issues, similar to how leaks around windows and roofing can cause problems.
When to Call a Professional
While boarding up a window is a manageable DIY task, there are times when you should absolutely call for professional help. We’ve found that recognizing these situations can save you a lot of trouble and potential expense down the line.
Assessing the Damage Severity
If the window break is due to a major incident, like a severe storm or a vehicle impact, there might be underlying structural damage to your home. In such cases, it’s best to get an expert opinion. They can assess the full extent of the damage, not just the window itself.
Signs You Need Professional Help
Consider calling a professional restoration company if:
- The window frame itself is severely damaged or compromised.
- You suspect damage to the surrounding walls or structure.
- There’s significant glass scattered inside, making safe cleanup difficult.
- The damage was caused by a natural disaster or accident.
- You’re uncomfortable or unsure about any part of the boarding-up process.
Professionals have the tools and expertise to handle complex situations safely and effectively. They can also perform the permanent repairs needed, addressing issues like water trapped under flooring or damaged drywall.
Protecting Your Home After Boarding
Boarding up is a temporary fix. The next step is to arrange for a permanent repair. Don’t delay this crucial step. The longer a window remains boarded, the more potential there is for secondary damage. This can include issues like ceiling stains after heavy rain.
Scheduling Permanent Repairs
Contact a reputable window repair or replacement company. Get quotes and understand the timeline for repairs. A professional will not only replace the window but also check for any related damage that might have occurred. This includes checking for any signs of rainwater coming through the ceiling.
Dealing with Potential Water Damage
If rain or wind has entered your home through the broken window, you might have water damage. Look for damp spots on walls, carpets, or furniture. Address any water damage promptly to prevent mold growth. Proper drying of affected areas is essential, much like ensuring proper drying after a leak.
Conclusion
Boarding up a broken window yourself is a practical step to secure your home and prevent further damage. By carefully measuring, cutting, and securely attaching plywood, you can create a temporary barrier. Remember to prioritize safety throughout the process. For situations involving extensive damage or if you’re unsure about the process, don’t hesitate to seek professional assistance.

What if I don’t have plywood?
If you don’t have plywood available, you can use thick plastic sheeting and heavy-duty tape as a very temporary measure for very small breaks. However, this offers minimal security and weather protection. For anything more substantial, acquiring plywood is highly recommended for a safe and effective board-up. It’s crucial to act before it gets worse.
Can I use cardboard to board up a window?
Cardboard is generally not strong enough to effectively board up a broken window. It can be easily penetrated by wind, rain, and potential intruders. For security and protection, plywood is the standard and most recommended material. You need something more robust to prevent issues like roof leaks during severe storms.
How long can I leave a window boarded up?
Boarding up a window is intended as a temporary solution. It’s best to have permanent repairs completed as soon as possible, ideally within a few weeks. Leaving a window boarded up for an extended period can lead to secondary damage, such as wood rot or pest infestations, and may even indicate underlying issues like water trapped under flooring.
What should I do if the window frame is damaged?
If the window frame is significantly damaged, boarding up might be more challenging. In such cases, it’s often best to call a professional. They can assess the frame’s integrity and determine the best course of action, which may involve reinforcing or repairing the frame before boarding or proceeding with replacement. This is important to prevent water intrusion from storm damage.
Is it safe to clean up broken glass myself?
Yes, it is generally safe to clean up broken glass yourself if you take proper precautions. Always wear sturdy, closed-toe shoes, thick gloves, and eye protection. Carefully sweep up larger pieces first. Then, use a damp paper towel or duct tape to pick up smaller shards and dust. Dispose of all glass fragments in a puncture-proof container. If the breakage is extensive or involves dangerous heights, call a professional.
