Before You Begin
You will need to have a helper or two to assist with attaching the plywood panels to your home—the wood can be heavy and unwieldy to hold. Be sure to wear safety glasses, gloves, and other personal protective equipment when operating power saws and drills. While the steps for installing hurricane panels over windows are similar regardless of the type of windows you have, the steps will vary depending on the type of siding you have.
- If your home has brick siding, you’ll need to use a masonry bit and screws to attach the boards to the home.
- If your home has vinyl siding, you’ll need to use different spacing when drilling holes for the fasteners to ensure the panels are attached to the home’s framing and not the weaker sheathing.
Step 1: Measure the windows.
Use a tape measure to measure the width and height of the window opening on a wood frame home. Add 8 inches to each measurement to allow the plywood boards to overlap the window by 4 inches on each side. The panels should be at least 5/8-inch, 21/32-inch, or 3/4-inch thick.
Step 2: Cut the plywood panels.
Using the measurements you took from Step 1, use a circular saw or track saw to cut the plywood panels to size, making sure to account for the overlap. (To save time and effort, take your window measurements to the lumber store and ask them to cut the plywood for you.) For windows that are larger than a sheet of plywood, use a 2×4 board to connect two panels together.
Secure the 2×4 to both pieces of plywood at the seam with 2½-inch screws spaced every 4 to 6 inches. To make sure each panel is matched to the right window, label each window board with a permanent marker as you cut each one and draw an arrow indicating which end goes up.
Step 3: Prepare the panels for hanging.
After cutting the panels, use a pencil, tape measure, and 4-foot level to draw a straight line 2 inches from each edge of the panel. If your home has vinyl siding, draw the line 3¼ inches in from the edges to ensure the fastener hits the framing surrounding the window when you install the panels.
Mark drill locations along the line at 12-inch intervals and at each corner. Drill holes at each location using a bit that’s slightly smaller than the screw or bolt you plan to use to attach it.
Step 4: Prepare the window for the plywood installation.
Begin by asking your helper to place the panel into position over the window, making sure it’s properly aligned. Then, use a pencil to mark hole locations through the predrilled holes in the plywood. Mark the corners of the panel on to the house surface using a pencil, then remove the panel.
Next, use the drill to make pilot holes that are about 2 inches deep at each drill reference point using a drill bit that’s slightly smaller than the fastener. If you’re drilling into brick, you’ll need to use a masonry drill bit. For vinyl, make sure you’re drilling into the studs that frame the window casing.
Step 5: Attach the plywood panels.
Use 3-inch-long, 3/8-inch lag screws to secure large plywood panels. For smaller panels, 2½-inch long, 1/4-inch lag screws will suffice. If you’re attaching the boards to a home with brick siding, use masonry screws.
Place the panels back into position over the window, using the corner marks made in the previous step to line them up. Use a power drill and the fasteners to secure each piece of plywood to each window.
Tips for Reusing Plywood Window Covers
If you live in a hurricane-prone region, it makes sense to create reusable window boards to avoid having to purchase and make new ones every time a hurricane threatens. By using the same panels each time, you are also limiting the wear and tear on your window frame from repeatedly installing and removing fasteners in different locations.
Your window panels will last longer if you coat them with an exterior paint or wood sealer. You can also install clips on the panels that make it easy to pop the boards in and out, eliminating the need to fasten the panels directly to the window frame each time you want to install them. Hurricane window clips are an especially good idea for homes with vinyl siding, as they eliminate the need to fill holes left by fasteners.
Final Thoughts
Boarding up windows is an effective way to prepare a home for the high winds of a hurricane, and it’s an inexpensive alternative to installing hurricane shutters. By using the methods described above, you can learn how to board up a window properly. When completing this project, remember to use the right fasteners and method to suit the type of siding on the home. Also, whenever using power tools such as a drill or circular saw, make sure to wear safety goggles.
