Board Up Windows for Hurricane: A Practical Florida Guide

Florida building codes require structures to withstand high wind loads, and your windows are the most vulnerable entry points. When wind breaches a house, sudden internal pressurization can blow the roof off. Boarding up windows for hurricane protection prevents that catastrophic pressure change and stops flying glass. Whether you plan to handle the installation yourself or hire help, you need the right materials and a timeline that beats the storm.

Key Takeaways for Hurricane Window Protection

• Material choice matters: 5/8-inch exterior-grade plywood is the minimum standard for temporary barriers, while storm panels offer reusable, code-compliant protection.
• Timing is critical: Install panels when a hurricane watch is announced, not during a warning, to avoid supply shortages and dangerous weather.
• Fastening systems differ: Track systems allow quick deployment, while wood screws or lag bolts provide maximum holding strength for direct mounts.
• Code compliance protects you: Florida Building Code dictates specific fastener types and spacing. Non-compliant installations can lead to insurance denials.
• Professional installation saves time: Scheduling a handyman before hurricane season ensures custom-fit panels and secure mounting hardware ready to deploy.

Why You Must Board Up Windows for Hurricane Safety

Boarding up windows serves two critical purposes: it blocks windborne debris from shattering the glass, and it keeps your home's structural envelope intact. Once a window breaks, hurricane-force winds enter the house and pressurize the interior. This uplift force can detach the roof and collapse the walls. Properly installed window coverings keep the weather outside where it belongs.

According to the Federal Emergency Management Agency (FEMA), windborne debris is a primary cause of property loss during high-wind events. The agency notes that once the building envelope is breached, internal pressure increases dramatically, raising the risk of catastrophic structural failure. Securing all openings prevents this dangerous pressurization. A solid barrier over your windows is your first line of defense against total property loss.

Plywood vs. Storm Shutters: Which Material Works Best?

Choosing the right material dictates your preparation speed and protection level. Plywood is cheap and accessible in an emergency, but permanent storm shutters offer faster deployment and higher impact resistance. Before a storm threatens your area, homeowners need to weigh the cost, storage space, and local building code requirements for plywood versus polycarbonate or metal storm panels.

Plywood vs. Metal Storm Panels

Pros and Cons of Plywood

• Pros: Inexpensive, readily available at hardware stores before season, cuts to any custom shape.
• Cons: Warps when wet, rots over time, heavy to lift, blocks all light, requires significant storage space.

Pros and Cons of Storm Panels

• Pros: High impact resistance, slides into permanent tracks quickly, nests compactly for storage, code-compliant.
• Cons: High upfront cost, requires precise track installation, sharp edges require gloves to handle safely.

How to Measure and Cut Hurricane Window Boards

Accurate measurements prevent gaps where wind can grab the edge of a board and rip it off the house. You need boards that overlap the window opening by at least four inches on all sides—this ensures the fasteners anchor into solid framing, not just the siding or window casing. Always measure twice and cut once to avoid wasting expensive materials during a storm panic.

1. Measure the opening: Measure the width and height of the window including the frame.
2. Add overlap: Add four inches to both the width and height measurements to ensure the board covers the framing.
3. Mark the plywood: Use a straight edge and carpenter's pencil to mark your cut lines clearly on the 5/8-inch plywood.
4. Cut the board: Use a circular saw with a fine-tooth blade for a clean edge. Label the board with a permanent marker indicating the room and window orientation.
5. Drill pilot holes: Drill pilot holes around the perimeter of the board, spacing them every 12 inches, staying two inches in from the edge.

Step-by-Step: Board Up Windows for Hurricane Deployment

When a storm approaches, speed and safety dictate your process. You'll need a helper to hold large sheets of plywood while you secure the fasteners. Never attempt to install heavy boards on a ladder during high winds. Set up your hurricane preparation steps early in the day while conditions are calm and dry.

1. Position the board: Lift the precut plywood over the window opening, ensuring it covers the framing by at least two inches on all sides.
2. Mark fastener locations: Push a pencil through the pre-drilled pilot holes to mark the framing or concrete beneath the siding.
3. Set the board aside: Remove the plywood and drill your anchor holes into the house framing using a masonry bit for concrete or a wood bit for framing.
4. Insert anchors: Tap lead sleeve anchors or plastic wall anchors into the drilled holes for a secure grip.
5. Secure the board: Reposition the plywood over the window. Drive the corrosion-resistant lag bolts or heavy-duty screws through the board and into the anchors until the board sits flush and tight against the wall.

Florida Building Code and Window Protection Rules

Florida has some of the strictest wind mitigation codes in the country. The Florida Building Code (FBC) requires that new construction in High-Velocity Hurricane Zones (HVHZ) use approved impact glass or permanent shutters. If you own an older home, you can still use plywood—but the code specifies minimum thickness, fastener type, and overlap dimensions to ensure the temporary barrier doesn't become flying debris itself.

Always check your local jurisdiction for specific permit requirements before installing permanent track systems. If you're unsure about structural compliance or lack the tools to install track mounts safely, professional handyman services can evaluate your home and install code-compliant hardware. Hiring a professional ensures your fasteners penetrate the structural framing, not just the exterior cladding.

When to Hire a Handyman for Hurricane Prep

Installing window protection becomes dangerous when you work at height or drill into unknown building materials. A professional handyman brings ladders, masonry tools, and structural knowledge to identify proper anchoring points. If you have two-story windows, a tile roof overhang, or stucco exteriors that require special drill bits, hiring a professional prevents costly damage to your home's waterproof envelope.

Professional installation also guarantees you have the right hardware stored and ready before a storm forms. Handymen can measure, cut, label, and store your custom panels. They can also install permanent header tracks so future deployments take minutes instead of hours. Scheduling this work between June and October requires advance booking—demand spikes the moment a storm enters the Gulf.

Frequently Asked Questions

How thick should plywood be for hurricane windows?

Plywood used for hurricane window protection should be at least 5/8-inch thick. Exterior-grade CDX plywood offers the best balance of strength and moisture resistance. Thinner plywood won't withstand the impact of heavy windborne debris and may fail during a storm, leaving your home vulnerable to structural pressurization.

Can I use OSB instead of plywood to board up windows?

Oriented Strand Board (OSB) isn't recommended for hurricane protection. While OSB meets structural shear standards for wall sheathing, it absorbs water faster than plywood and delaminates under heavy rain. OSB also splinters upon impact more easily than solid plywood, reducing its ability to block debris during a high-wind event.

How far in advance should I board up my windows?

Install window protection when the National Hurricane Center issues a Hurricane Watch for your area, which typically occurs 48 hours before anticipated tropical storm conditions. Waiting for a Hurricane Warning leaves you 36 hours or less—risking hardware store shortages, long lines, and dangerous installation conditions as winds pick up.

What type of fasteners are best for hurricane plywood?

Use 3-inch long, corrosion-resistant lag screws or pan-head wood screws with washers. For concrete or brick homes, use 1/4-inch diameter sleeve anchors or expansion bolts. Skip standard drywall screws—they're brittle and snap under wind loads. Space fasteners every 12 inches around the perimeter of the board.

Does boarding up windows affect my homeowners insurance?

In Florida, installing code-compliant opening protection often qualifies you for wind mitigation credits on your homeowners insurance policy. However, temporary emergency plywood doesn't usually qualify. Permanent storm shutters or impact-rated glass typically trigger premium discounts. Contact your insurance provider to see what documentation they require for wind mitigation credits.
