Can You Board up Windows Yourself After a Disaster?
Last updated October 26, 2026
The short answer
Why Board Up Windows
After a storm, flood, or other disaster, broken windows leave your home open to rain, wind, and pests. Boarding them up protects the inside from further water damage and keeps debris from blowing in. It also helps secure your home while you wait for repairs.
You can do this yourself if the window is on the ground floor and you have the right materials. For windows above the first floor, or if the frame is damaged or wet, you need a ladder and extra care. If you feel unsteady or the area is unsafe, call in local water damage pros to do the task.
What You Need
Start with plywood that is at least 5/8 inch thick. Thinner boards bend and break under pressure. Measure the window opening, then cut the plywood to fit snugly inside the frame. You also need a drill, screws, and a screwdriver or impact driver.
Use screws rather than nails because screws hold better and are easier to remove later. For each board, place screws about every 12 to 16 inches along the edges. If you are boarding multiple windows, label each board so you know which one goes where.
- Plywood 5/8 inch or thicker
- Drill with screwdriver bits
- Screws at least 2 inches long
- Tape measure and pencil
- Safety glasses and work gloves
- Ladder only for ground-floor windows
Step by Step
First, clear any broken glass from the frame and sill. Wear heavy gloves to protect your hands. Measure the opening from inside, then cut the plywood to fit. If the frame is wet or warped, cut the board slightly smaller so it slides in easily.
Hold the board against the window from the outside. Drill pilot holes through the plywood into the frame, then drive the screws. Work from the center outward to keep the board flat. Check that each screw bites into solid wood, not rotted or damaged areas.
When to Call the Pros
Some situations are too risky for a homeowner. If the window is on the second floor or higher, or if the roof is damaged, let the pros handle it. They have ladders, lifts, and experience working at heights. Also call the pros if you see sagging ceilings or wet drywall near the window, as that indicates structural issues.
Boarding up is a temporary fix. The pros can also assess the water damage behind the wall and start drying out the area. For severe flooding, you may need flood damage cleanup in addition to boarding. If you live in Cincinnati, keep your local emergency numbers handy for quick help.
- Upper floor windows are dangerous without proper equipment
- Wet or rotted frames need professional repair
- Structural damage may be hidden behind the wall
- Large picture windows are hard to cut and fit alone
- If you feel dizzy or short of breath, stop and see a doctor
Safety First
Never work alone if you can avoid it. Have someone hold the ladder or hand you tools. Wear sturdy shoes and avoid walking on wet floors. Turn off electricity to the room if water has reached outlets or switches.
If you smell gas or hear hissing, leave the house and call the gas company from outside. Do not touch downed power lines or anything touching them. If you feel unwell from mold or debris, see a doctor. Boarding up is important, but your health comes first.

How long does a board-up last?
A properly installed plywood board can last for weeks or months, depending on the weather. Use exterior-grade plywood and stainless steel screws to resist rust. Check the boards after heavy rain or wind and tighten any loose screws.
Can I use plastic sheeting instead of plywood?
Plastic sheeting is only a short-term fix for a few days. It can keep rain out but tears easily in wind. Use plywood for any window that needs protection for more than a day. For small cracks, plastic and duct tape can work temporarily.
What if I can't reach the window from outside?
You can board from inside if the window is broken and you can access the frame. Cut the plywood to fit the interior opening, then screw it into the frame. For security, use screws that are long enough to anchor into the wall studs.
