Why Securing Openings Is Your Best Defense in a Storm

During a severe storm or hurricane, the preservation of your home’s structural integrity relies entirely on keeping wind and water outside. Once a single window shatters or a door yields to the pressure, high-velocity winds rush inside, creating an upward force that can literally lift the roof off a house. Securing these entry points isn’t just about preventing broken glass; it is about maintaining the pressure seal of your entire living space.

Water damage is another major threat that proper boarding and sealing prevent. Wind-driven rain can penetrate even the smallest gaps around window frames and doors, leading to ruined drywall, warped flooring, and structural rot. Taking a proactive approach to reinforcing these weak spots with heavy-duty physical barriers and tight seals is the single most cost-effective way to mitigate catastrophic storm damage.

Window Clips – Plylox Hurricane Window Clips

Installing plywood covers over windows is a standard storm prep tactic, but drilling directly into your home’s exterior brick or stucco can cause permanent damage. Window clips solve this issue by anchoring plywood securely inside the window casing without the need for screws or nails. They utilize tension to hold the wood in place against extreme wind loads, making boarding up a fast, clean, and damage-free process.

Plylox Hurricane Window Clips are the industry standard for this task, constructed from rugged, tempered stainless steel that resists rust and won’t buckle under pressure. These clips slip easily onto the edges of the plywood sheets and wedge tightly into brick, concrete, or wood window casings. The tension design ensures that the harder the wind blows against the plywood, the tighter the clips grip the casing walls.

• Compatible with 1/2-inch and 5/8-inch plywood
• Requires a 2-inch minimum casing recess
• Constructed from rust-resistant stainless steel

Before purchasing, verify your window inset depth to ensure the clips will have enough clearance to seat properly. They are sold in multi-packs, and you will typically need four clips for windows under four feet, and six or more for larger openings.

These clips are ideal for homeowners with brick or concrete stucco exteriors who want to avoid drilling permanent holes into their facades. However, they are not compatible with flush-mounted windows that lack a recessed casing, or windows framed with thin vinyl siding trim that cannot withstand high pressure.

Door Security Bar – Master Lock 265D Security Bar

Exterior doors, particularly those with latch systems or sliding tracks, are highly vulnerable to being blown open by powerful wind gusts or forced by debris impacts. A door security bar acts as a physical brace, reinforcing the door from the inside and transferring external pressure directly into the floor. It provides an immediate layer of defense that keeps entry doors shut tight even if the locks or latches fail.

The Master Lock 265D Security Bar stands out because of its robust construction and highly adjustable design. It features a pivoting ball joint at the base that ensures full contact with the floor, paired with a non-marring rubber foot that prevents slipping on hardwood, tile, or carpet. The top yoke fits snugly under standard door knobs, and the entire assembly can adjust to fit a wide variety of entryways.

• Adjusts from 27.5 inches to 42 inches
• Features 20-gauge steel construction
• Equipped with a non-marring rubber foot

Using this bar is straightforward, but it requires a solid floor surface to bite into. To use it on sliding patio doors, simply remove the top hook portion and place the bar horizontally in the door track to prevent the door from being slid open or popped out of its frame.

This bar is perfect for anyone looking to secure front doors, side doors, or sliding glass doors without installing permanent, unsightly deadbolts or track locks. It is not suitable for doors that open outward, as the bracing physics rely on resisting inward force.

Window Film – 3M Safety & Security Window Film

Flying debris is a major hazard during storms, capable of shattering glass and sending dangerous shards flying into your living spaces. Security window film acts as an invisible protective membrane applied directly to the glass surface. While it does not prevent the glass from cracking under high impact, it holds the broken fragments together within the frame, preventing wind and rain from entering the home.

3M Safety & Security Window Film is engineered with micro-layered, tear-resistant polyester technology that significantly increases glass resilience. This clear film allows natural light to enter while providing a robust barrier that deters both storm damage and forced entry. It is designed to bond seamlessly with standard glass using a strong adhesive system that maintains its clarity and strength for years.

• Features 8-mil micro-layered polyester construction
• Blocks up to 99% of harmful UV rays
• Holds shattered glass together securely

Application requires patience and precision; you must thoroughly clean the window pane to remove all dust, spray a soapy water solution, apply the film, and squeegee out air bubbles. It is available in various thicknesses, with the 8-mil thickness being the recommended choice for storm mitigation.

This film is an excellent year-round option for homes with large picture windows or glass doors where putting up storm shutters is impractical or visually undesirable. It is not a complete substitute for plywood shutters in high-category hurricanes, but it serves as an invaluable secondary line of defense.

Silicone Sealant – GE Advanced Silicone 2 Window & Door

High winds can drive rain sideways, forcing moisture into microscopic gaps around your window frames and doors where traditional caulking has degraded. A high-quality silicone sealant acts as a flexible, waterproof gasket that stops water infiltration cold. Sealing these exterior seams before storm season prevents rot, structural decay, and interior water damage.

GE Advanced Silicone 2 Window & Door sealant is the premium choice for exterior waterproofing due to its advanced formulation. Unlike acrylic caulk, this product remains permanently flexible, meaning it won’t crack, shrink, or crumble when exposed to extreme temperature swings or structural shifting. It is rain-ready in just 30 minutes, which is crucial when prepping your home on a tight, pre-storm timeline.

• Formulated with 100% silicone material
• Fully rain-ready in 30 minutes
• Bonds to wood, vinyl, metal, and masonry

This sealant adheres beautifully to wood, vinyl, metal, and masonry, but it cannot be painted over once cured. If aesthetics are a priority, select the clear version or match the color (such as white or bronze) directly to your window trim.

This product is a must-have for annual home maintenance and last-minute prep to secure degraded seals. It is not suitable for wet surfaces during application, so apply it while the weather is still dry before the storm arrives.

Weatherstrip Tape – Duck Brand Self-Adhesive Foam

Small gaps around door jambs and window sashes not only let drafts in but also allow high-pressure storm winds to whistle through, creating pressure imbalances inside the home. Weatherstrip tape acts as a compressible seal that fills these voids, blocking wind-driven rain and airborne debris. It is an inexpensive, fast-acting upgrade that significantly tightens your home’s envelope.

Duck Brand Self-Adhesive Foam Weatherstrip is highly recommended for its durability and resilience. Made from premium, high-density foam, it compresses easily to form a tight seal and springs back to its original shape once the door or window is opened. The self-adhesive backing is exceptionally strong, ensuring the tape stays in place even under high humidity and temperature changes.

• Premium high-density foam material
• Strong self-adhesive backing
• Available in various widths and thicknesses

To ensure proper adhesion, always clean the application surface with rubbing alcohol to remove grease and dirt before pressing the tape down. It comes in various widths and thicknesses, so measure your door and window gaps carefully to buy the size that compresses without preventing the door from latching.

This tape is ideal for quick, DIY drafts and moisture sealing on older doors and double-hung windows. It is not a permanent solution for heavily warped doors that require mechanical adjustments or new hardware.

Concrete Anchors – Tapcon Star Flat Head Screws

For homes with concrete block or brick exteriors, mounting heavy plywood shutters requires anchors that won’t pull out under intense wind pressure. Traditional wood screws or plastic anchors will fail when subjected to the sheer forces of a major storm. Dedicated concrete anchors cut their own threads directly into masonry, creating a mechanical bond that holds fast.

Tapcon Star Flat Head Screws are the gold standard for masonry fastening, featuring a specialized thread design that cuts clean threads into concrete, brick, and block. The star drive (Torx) head prevents stripping and slipping during installation, allowing you to drive them smoothly with high torque. They are coated with a corrosion-resistant finish that protects against rust from humid coastal air.

• Features a patented dual-thread design
• Designed with a strip-resistant star drive head
• Finished with a corrosion-resistant coating

Using these anchors requires a hammer drill and a carbide-tipped masonry drill bit sized precisely to the anchor specifications (usually 3/16-inch or 1/4-inch). It is essential to drill the pilot hole slightly deeper than the anchor penetration depth to allow room for dust buildup during installation.

These anchors are essential for anyone securing heavy shutters or plywood directly to brick, concrete block, or stucco homes. They are not meant for wood-frame homes, where heavy-duty lag screws should be used instead.

Cordless Drill – DeWalt 20V Max Drill Driver Kit

When boarding up a home, manual screwdrivers are simply out of the question; you need speed, power, and mobility to secure multiple openings before the weather turns. A reliable cordless drill allows you to pre-drill plywood sheets, drive concrete anchors, and mount hardware rapidly without dealing with tangled extension cords. It is the central power tool that makes all other boarding efforts possible.

The DeWalt 20V Max Drill Driver Kit is an exceptional choice, offering a compact, lightweight design balanced with professional-grade power. It features a high-performance motor that delivers plenty of torque, making it highly capable of drilling through thick plywood and masonry alike. The kit includes a reliable lithium-ion battery that holds its charge for months, an ergonomic handle, and a built-in LED light to illuminate dark work areas.

• Delivers up to 300 unit watts out (UWO) of power
• Includes a high-capacity 20V lithium-ion battery
• Equipped with a built-in LED work light

When using this drill for storm prep, keep a spare battery on the charger so you can swap out without interruption. Utilize the low-speed, high-torque setting (Speed 1) when driving concrete anchors to prevent stripping the masonry threads.

This drill is a versatile investment for any homeowner tackling storm prep and general maintenance tasks. It may be overpowered for simple indoor hanging projects but is absolutely necessary for heavy-duty boarding.

Waterproof Tape – Gorilla All Weather Duct Tape

When storm damage does occur or unexpected leaks spring up mid-storm, you need a quick, reliable way to patch breaches immediately. Standard duct tape degrades quickly under water exposure and UV rays, losing its grip when you need it most. Heavy-duty, waterproof tape provides a temporary but incredibly strong seal that holds up against wind, rain, and extreme temperatures.

Gorilla All Weather Duct Tape is specifically engineered to withstand harsh outdoor elements. It features a concentrated, thick adhesive layer that bonds to rough, wet, or uneven surfaces, along with a heavy-duty, weather-resistant shell that resists UV degradation. This tape remains functional in temperatures ranging from -40°F to 200°F, ensuring it won’t melt in summer heat or crack in freezing winds.

• Heavy-duty weather-resistant shell
• Temperature range from -40°F to 200°F
• Highly concentrated extra-thick adhesive layer

For the best results, try to dry the surface as much as possible before application, pressing the tape down firmly to activate the adhesive. This tape is exceptionally strong, so keep a pair of scissors or a utility knife handy, as it is difficult to tear cleanly by hand.

This tape is a must-have emergency kit item for patching torn tarps, securing loose siding, or sealing cracked window panes temporarily. It is not designed for permanent repairs, and the aggressive adhesive can leave a sticky residue that requires rubbing alcohol or adhesive remover to clean off later.

How to Safely Measure Your Openings Before a Storm

Accurate measurements are the foundation of successful storm preparation; a plywood barrier that is even an inch too small will fail to protect your window frame. To get precise dimensions, always measure the inside width and height of the window casing rather than the glass itself. Take three measurements for each dimension—top, middle, and bottom for width; left, middle, and right for height—and use the smallest measurement to ensure your plywood fits into the recess.

Labeling your measurements is just as crucial as the numbers themselves. Create a master diagram of your home and assign a specific number or name to every single window and door (e.g., “Master Bedroom East”). When you cut your plywood sheets, write these corresponding labels directly on the wood with a thick waterproof marker so you don’t waste precious time playing matching games when a storm is approaching.

Setting Up a Smart and Fast Boarding Routine

In the high-stress hours before a storm, organization is your greatest asset. A smart boarding routine begins with staging your materials in an accessible, dry area like a garage or shed, arranged in the order they will be installed. Group your clips, anchors, drill bits, and safety gear together in a dedicated “storm bin” so you aren’t hunting through toolboxes when every minute counts.

If you are boarding up alone, work from the most vulnerable side of the house first—typically the side facing the oncoming wind—before moving to the shielded areas. Practice installing one or two window covers during a calm weekend early in the season. This dry run helps you identify missing tools, gauge how long the process takes, and build the muscle memory needed to work efficiently under pressure.

Maintaining Your Gear So It Is Ready for Next Season

Storm prep equipment sits idle for most of the year, which makes it highly susceptible to rust, battery degradation, and dry rot if stored improperly. After the storm season passes, take the time to clean and dry all reusable hardware, including window clips and door bars. Wipe down metal surfaces with a light coat of multi-purpose oil to prevent corrosion while stored in humid garages or basements.

Inspect your power tools and batteries, ensuring they are stored in a climate-controlled space rather than a hot attic or cold shed, which shortens battery life. Finally, check your sealants and tapes; silicone tubes and adhesive rolls have a limited shelf life and should be replaced if they have dried out or lost their stickiness. Taking these steps ensures your gear is ready to perform the moment the next warning sounds.

Conclusion

Securing your home against severe storms doesn’t have to be an overwhelming or chaotic experience. By investing in the right tools and establishing a clear preparation routine, you can face storm season with confidence. A small amount of foresight today ensures your home remains a safe, dry haven when the elements put it to the test.
