The storm came in swinging, and your windows and doors took the punch. Now you’re staring at a jagged hole that’s basically a VIP entrance for rain, raccoons, and people who don’t knock. You don’t need to turn your home into a fortress forever, but you do need an emergency board-up that keeps the weather and troublemakers out until repairs happen. Here’s a straight-talking homeowner guide to window and door boarding that actually holds, with gear you can buy today and steps you can handle safely. When it’s too big, too risky, or too weird, Best Option Restoration of Travis County is on call 24/7 to lock it down fast.
Why Boarding Up Fast Matters
Storm-breached openings are invitations for secondary damage, which is where costs explode. Wind-driven rain does not politely stop at the sill. It soaks framing, wicks into drywall, and feeds mold. Openings also attract pests and unauthorized visitors. Every hour counts. A fast, well-secured panel limits water intrusion, stabilizes indoor humidity, protects belongings, and makes your insurance adjuster’s job easier. Even if you plan on permanent fixes in a day or two, you still need a strong temporary barrier that resists prying, flexing, and more bad weather.
Materials That Actually Hold
If you’re going to swing a drill in storm aftermath, use materials that won’t fold at the first gust. The short list below prioritizes strength, weather resistance, and compatibility with standard framing. Cheap shortcuts tend to leak, sag, or rip out when the wind takes a breath.
Plywood Thickness And Type
Pick exterior grade CDX plywood. For typical residential windows, go at least 5/8 inch thick. For doors, patio sliders, and oversized openings, use 3/4 inch. Thinner panels flex and strip fasteners. Avoid OSB for exposed board-ups unless it is truly short term. OSB absorbs water faster and loses strength when wet, which defeats the whole point. Consumer Reports and other preparedness guides recommend exactly this approach for storm protection and temporary closure.
Fasteners That Bite
Bolts and structural screws are your friends. Nails are fast but unreliable for security and uplift. Here’s what works:
- Carriage or hex through-bolts with washers and nuts for the strongest clamp, especially on doors and large openings.
- Structural screws or lag screws long enough to penetrate solid framing by at least 1.5 inches. Aim for studs, headers, and jambs.
- Wide washers under screw heads stop plywood from pulling through under wind load.
Property preservation standards favor carriage bolts and interior 2×4 braces because they resist prying and distribute load far better than nails or light wood screws.
Bracing And Backing
An interior 2×4 brace spreads force across the opening and lets you use through-bolts for a serious clamp. If you can’t access the interior safely, drive structural screws into exterior framing members and use more fasteners at closer intervals. For unusually wide spans, add a vertical or horizontal 2×4 on the outside face under the plywood to stiffen the panel. Think of it as ribs for your temporary shield.
Sealants And Weather Barriers
Edge sealing is the difference between a shield and a funnel. A bead of exterior-grade sealant or a closed-cell foam gasket behind the plywood reduces wind-driven rain and cuts drafts. If the rain is still coming sideways, add a strip of flashing tape along the top edge so water sheds over the panel, not behind it. You’re not building a boat, but you do want to stop the obvious leaks.
Quick Sizing And Cutting
Measure the opening width and height. Add 4 to 6 inches to each dimension so your panel overlaps the framing by roughly 2 to 3 inches on all sides. That overlap is where your fasteners grab real wood and create a seal. Mark your cut lines on the plywood, then label each panel by room and opening before you pick it up. If you’re doing several windows, predrill a hole pattern that repeats so you can mount panels faster without measuring every time. A general pattern that works: fasteners within about 6 inches of each corner and then spaced about 12 to 16 inches along each edge. Stay at least 1 inch in from the plywood edge to prevent splitting.
When you cut, keep edges straight for a snug fit. If the opening is out of square, scribe the panel to match the exterior trim. Gaps let water and wind win. If you need to cut around a latch or hardware on a door, make a tight notch instead of removing the hardware unless it is damaged.
Install Steps Without Drama
Start with safety gear: gloves, eye protection, and boots. Broken glass is sneaky. Sweep or vacuum up loose shards so your ladder and your feet survive the day. If the frame is splintered, trim ragged pieces flush so the panel seats flat.
Set the plywood so it overlaps evenly, then hold it in place with a helper or a temporary screw. If you’re using through-bolts with an interior 2×4, hold that brace horizontally or vertically across the inside of the opening. Drill a matching hole through the plywood, the window or door opening, and the 2×4. Insert bolts with washers under both the nut and the head. Snug them up evenly and avoid crushing the siding. You’re clamping the assembly, not trying to make toothpicks.
If you’re fastening from the outside only, drive structural screws into studs, headers, or the solid jambs around doors. Do not count on thin trim or brick mold to hold anything. Keep the spacing tight, especially on the windward side. Once secured, run a bead of exterior sealant along the top and sides. If wind is gusty, add a short 2×4 prop on the inside against the back of the panel to stop flexing, assuming the interior is accessible and safe.
Doors Need Different Love
Doors, especially sliders and French doors, have larger glass areas and taller spans that flex more in wind. Use 3/4 inch plywood for these. On a standard swing door, remove loose glass and secure a full-height panel that overlaps the entire frame, not just the slab. Through-bolting with an interior 2×4 is ideal for security and wind resistance. On patio sliders, span the full opening with one large panel or two panels joined over a center stud or mullion. Avoid drilling through delicate door hardware unless it is already toast. If the frame is cracked, add exterior 2×4 stiffeners screwed into the structural framing and then attach the plywood to those stiffeners.
Safety Before Tools
Pause and look up. If there are downed power lines, sparks, the smell of gas, or a half-leaning tree over your roof, step back and call the utility company or emergency services. Never set a ladder against a damaged surface that might shift. Do not operate corded tools in standing water. If the wall around the opening looks bowed, split, or out of plumb, it could be bearing load. This is a professional situation. Tape off the area and make the call.
When Should You Call A Pro?
There is DIY, and then there is not-today. Call a professional emergency board-up team if any of the following is true:
- The opening is larger than a single sheet of plywood or spans multiple windows and doors.
- There is roof, wall, or structural damage near the breach.
- You cannot safely access the interior for through-bolting or bracing.
- The property is historic or has specialty windows that need careful treatment.
- You need insurance-ready documentation with moisture readings and a mitigation plan.

Insurance And Documentation
Before you lift a panel, take wide shots and close-ups of every damaged opening, surrounding walls, and any water inside. Photograph the exterior from multiple angles. Keep receipts for plywood, fasteners, blades, fuel, and any labor. Most policies require you to mitigate further damage after a loss. A quick, properly installed board-up meets that expectation. If professionals perform the work, ask for a write-up with photos and materials used. This is also a good time to start a simple log: date, time, actions taken, and any issues found like wet carpet or ceiling stains.
After The Board-Up
With the hole closed, shift to moisture control. If water got inside, pull up wet rugs, use towels to blot standing water, and run dehumidifiers if the power is safe. Box fans can help move air, but only if there is no electrical risk. Open interior doors to encourage airflow. If drywall got soaked, it may need professional drying or removal to stop mold. Do not crank the heater to sauna settings. Aim for steady drying, not a blast furnace.
Outside, check the top edge of each panel during the next rain. If you see water streaking behind the panel, add flashing tape across the top and reseal the sides. Do not seal the bottom edge completely on very wet interiors. A small gap can help moisture vent out without drawing in more rain, especially if the opening is protected by an overhang.
Common Mistakes To Skip
Let’s save you from the greatest hits of bad board-ups:
Using OSB for more than a quick day or two in wet weather. It swells, flakes, and loses bite around fasteners.
Hitting only exterior trim. Thin trim is not structure. Miss the studs and the panel peels off like a sticker.
Undersizing panels. You want at least 2 to 3 inches of overlap on all sides so screws land in real framing.
Nails only. They pull out under wind and are easy to pry. Bolts and structural screws are stronger and safer.
Skipping gloves and eye protection. Glass doesn’t care how careful you think you are.
Blocking your only safe exit. Always leave one accessible, secure door if you’re staying onsite.
Forgetting to label panels. If they need to come down and go back up, clear labeling saves time and drilling mistakes.
Special Cases: Historic Homes
Historic trim and fragile sashes deserve extra care. Avoid driving fasteners through original decorative casing when possible. Use through-bolts with interior 2×4 braces that bear on structural jambs, not ornate trim. In some cases, building a temporary compression frame that clamps around the opening is the least invasive method. Best Option Restoration works on historic properties and coordinates with preservation rules, including non-destructive tarping and reversible board-ups. If that’s your house, see how we stabilize historic structures without turning them into Swiss cheese.
What If You Don’t Have Plywood?
Sometimes the lumber aisle is a ghost town after a storm. If you cannot source proper plywood immediately, you can create a solid short-term layer with thick poly sheeting and furring strips, then upgrade as soon as materials arrive. Stretch 6 mil poly tight across the opening, sandwich the edges with 1×3 or 1×4 boards, and screw through into framing. This is not a theft deterrent and it will not stop flying debris, but it will slow rain and wind infiltration while you hunt down real panels. Replace with 5/8 or 3/4 inch CDX and proper fasteners as soon as you can.
How To Find Framing You Can Trust
Hitting studs and headers is half the game. On standard windows, studs run up each side, and a header spans above the opening. Doors have beefier jambs and headers. A good stud finder helps, but you can also look for nail lines in siding or sheathing patterns that hint at stud spacing, often 16 inches on center. If brick veneer covers your exterior, aim fasteners into the solid wood jamb or use through-bolts with interior bracing. Do not drive screws into brick or mortar for primary support unless you have anchors rated for that job and a drill suited to masonry, and even then, wood framing is usually the better target for a fast emergency board-up.
Fastener And Brace Cheat Sheet
Quick reference for typical residential openings:
| Opening | Panel | Fastener Setup | Spacing Guide |
|---|---|---|---|
| Standard Window | 5/8 in CDX | Structural screws into studs and header with washers | Within 6 in of corners, then every 12-16 in along edges |
| Large Window/Slider | 3/4 in CDX | Through-bolts with interior 2×4 brace, or exterior screws plus added stiffener | Bolts near corners, then about every 18-24 in; screws 12-16 in |
| Entry Door | 3/4 in CDX | Through-bolts across jambs with interior brace | Two bolts per side minimum plus top and bottom, tighten evenly |
Tools That Make This Easier
You do not need a contractor’s trailer, but the right kit saves time and swearing. A circular saw with a good plywood blade, a cordless drill/driver with impact-rated bits, a stud finder, tape measure, carpenter’s pencil, safety glasses, cut-resistant gloves, pry bar for loose trim, utility knife for flashing tape, and a tube or two of exterior sealant cover most board-ups. If glass is everywhere, a shop vacuum with a fresh bag will be your new best friend. For higher openings, use a real ladder on a flat surface, never a stack of buckets pretending to be a scaffold.
Weatherproofing Edges That Leak
Even a tight panel can let wind push water around the sides. Start with a continuous bead of sealant on the top and sides of the overlap. If rain keeps sneaking in, run a strip of waterproof flashing tape across the top seam and a few inches down each side. Think shingles: water always needs a path over, not behind. If you have to leave a panel on for a week or two, check the seal after heavy storms and reapply as needed. Do not trap gallons of interior moisture by sealing every crack if the inside is wet. Controlled ventilation can be useful while you wait for mitigation crews.
Removing Boards Without Damage
When it is time for glass replacement or permanent doors, back out screws instead of prying. If you used through-bolts, hold the bolt head while you loosen the nut so you do not grind the siding. Score any stubborn sealant with a utility knife rather than yanking. Keep panels intact if you think you may need them again during repairs. Clean up remaining sealant and patch any fastener holes in trim or siding with exterior filler or caulk until the full repair is done.
Board-Up FAQ
Can I Use Drywall Screws For An Emergency Board-Up?
Skip them. Drywall screws are brittle and snap under load. Use structural screws or lags rated for exterior use, with washers to spread load.
How Long Can I Leave Plywood Up?
It is a temporary solution. A few days to a couple of weeks is typical. The longer it stays, the more you should check fasteners, reseal edges, and watch for moisture problems inside.
Do I Board From The Inside Or Outside?
Outside is faster and often safer because you can shed water away from the wall. Through-bolting that clamps an interior 2×4 to the exterior panel is the strongest of both worlds. Interior-only panels can work but are weaker against wind and prying unless they are fully braced.
Is OSB Ever OK?
Only for very short exposure and when you can replace it soon. In wet weather, OSB degrades quickly. Plywood holds up better outdoors.
Will This Satisfy Insurance?
Insurers generally expect reasonable steps to prevent further damage. Photograph, save receipts, and consider a professional board-up when the loss is significant. Services like Best Option Restoration also document conditions for your claim.
