The short answer
Measure and Cut
Start by measuring the width and height of each window frame from the outside. Add 4 inches to each dimension so the plywood overlaps the frame by 2 inches on every side. This overlap gives the board a solid surface to grip.
Use a circular saw to cut 5/8-inch exterior-grade plywood to those measurements. If you have multiple windows, label each board with its matching window to avoid confusion. Pre-drill pilot holes for screws about 6 inches from each corner and every 12 inches along the edges.
Secure the Boards
Hold the plywood against the window frame, making sure it covers the entire opening. Drive 3-inch deck screws through the pilot holes into the frame. For masonry or brick, use concrete anchors instead. Space the screws evenly to hold the board flat and tight.
If you expect high winds, add extra screws along the middle of the board. You can also use heavy-duty brackets to reinforce the corners. Avoid using nails, because they can pull out under pressure. Screws grip better and are easier to remove later.
- Use 5/8-inch plywood for most windows
- Add 4 inches to each measurement for overlap
- Pre-drill holes to prevent wood splitting
- Choose 3-inch deck screws for wood frames
- Use concrete anchors for brick or stone
- Label boards to match each window
Protect the Glass
Boarding up windows is about more than just covering the glass. The plywood also shields the frame and seal from rain and flying debris. If the glass is already cracked, tape it with masking tape in a crisscross pattern before covering it. This reduces shattering.
For extra protection, place a layer of plastic sheeting between the glass and the plywood. This helps keep water out if the board shifts. Check the boards after a storm to ensure they are still secure. Replace any that have loosened.
Know When to Call the Pros
Boarding up windows is a practical short-term step, but it does not fix the underlying damage. If water has already entered your home, you need more than plywood. Water damage can soak into walls, floors, and insulation, leading to mold and rot.
If you live in Rowlett, spring storms can bring hail and high winds. Acting quickly to secure windows helps, but professional assessment is often needed. The pros can inspect for hidden moisture and recommend proper drying and repairs. You can also check with local water damage pros for guidance.
After the Storm
Once the storm passes, remove the boards carefully. Inspect the window frame for cracks, warping, or water stains. If you find damage, address it before re-installing the window. Leaving boards up too long can trap moisture against the frame.
If the window is beyond repair, consider replacement. Water-damaged frames can weaken the structure. The pros can handle window replacement and also check for moisture in the surrounding walls. For now, boarding up is a solid first response to protect your home.

What type of plywood should I use?
Use 5/8-inch exterior-grade plywood. It is thick enough to resist wind and debris. Thinner boards may bend or break. Check for a smooth surface without knots or warps for a snug fit.
How long can I leave boards on my windows?
Boards are a temporary measure. Leave them on for a few days to a couple of weeks at most. Prolonged covering can trap moisture and cause rot. Plan for a permanent repair once the weather clears.
Can I board up windows from the inside?
It is safer to board from the outside, but you can do it from inside if needed. Inside boarding offers less protection because wind pressure can push the board inward. Use longer screws to reach the frame securely.
