Locks, shutters and door hardware before a storm

Why doors and locks matter in a storm

In a hurricane, a door is part of the building envelope. Wind pressure pushes against it, and if a door fails, the pressure inside the home changes in ways that can stress the roof and walls. Most of the attention goes to windows and garage doors, which is fair, but exterior doors also deserve a close look. A door that is weak, poorly latched or badly fitted can be the first thing to give way.

Locks play two roles. They hold the door closed against force, and they keep the door shut against wind pressure that tries to pull or push it open. A latch that is worn, a bolt that does not fully extend or a strike plate that is loose may be unnoticed in calm weather and unable to cope when wind is pushing hard.

Storms also create a security question. Evacuated neighborhoods, damaged doors and broken windows can leave homes exposed. A sound lock and a door that closes properly give you one less worry when you are away. This page helps you work through the main checks in a calm period, well before a storm is forecast.

Start early and work through the home

The best time to check door hardware is early in the season or before it begins, when hardware stores are not crowded and technicians are not overloaded. Waiting until a storm is forecast means competing for appointments and supplies at the same time as everyone else. If you have a concern about a door, handle it in the quiet weeks.

Walk through the home and list every exterior door: front, rear, garage entry, patio or slider, side doors and any French doors. Add gates and the garage door itself, even though the garage door is a separate subject. For each, note its type, its lock, how it closes and anything that has changed lately.

Our guide to the doors that matter most helps you rank which ones need attention first. In a storm, the largest openings and the ones with the lightest hardware tend to be the highest priorities.

Checking latches, bolts and strike plates

Close the door and look at how it sits in the frame. The gap around the edge should be even. Operate the deadbolt and make sure it extends fully into the strike plate without having to push, pull or lift the door. If you have to force it, the door or frame may have shifted. A bolt that only half engages gives little protection against wind or force.

Look at the strike plate. Screws should be tight and long enough to reach the framing behind the jamb. Loose or short screws are a common weakness, and replacing them is a modest repair that a technician can do quickly. If the wood around the strike plate is soft, cracked or damp, the frame may need more attention. See door reinforcement and strike plates for what is involved.

Check handles and levers. They should turn smoothly and spring back. Latches that stick or fail to retract may be corroded. Many double doors and French doors rely on a latch or a flush bolt to hold the inactive door, and a worn flush bolt may not hold under pressure. If you are not sure what you are looking at, take photos and describe it when you call.

Doors that swell, stick or no longer close squarely

Florida humidity and rain cause wood doors and frames to swell, and ground movement or settling can shift frames over time. A door that rubs, sticks or needs a hard shove to latch is a door that is out of alignment. In a hurricane, a door that does not close properly cannot be relied upon to stay shut under pressure.

Do not simply plane the door or force the latch. Planing may fix the stick but leave a gap, and forcing a latch can break it. A technician or carpenter can find the cause, which might be a hinge screw that has loosened, a frame that has moved or a strike plate that needs repositioning. Fixing the cause is more reliable than treating the symptom.

Hinges deserve a look. Exterior doors should have long screws in the hinge plates that reach the framing. Loose or short screws let the door sag and can fail under load. Our page on door frame repair for lock fit describes how frames and strike plates are put right.

Sliding doors, French doors and large glass openings

Large glass doors are among the most exposed openings in a Miami home. Sliding doors in particular can bow in strong wind, and a factory latch may release if the door flexes. Many homes have impact-rated glass or shutters on these openings, and where they do not, owners often rely on temporary protection.

Whatever protection you use, the lock and latch still matter. Make sure the slider's latch catches fully, that the door runs smoothly in its track and that any secondary lock or bar is in working order. Track debris should be cleared, and rollers that are worn may need replacement. A slider that rattles in its frame in normal conditions will behave worse in a storm.

For double doors, check that the inactive leaf is held at the top and bottom by flush bolts that move smoothly and engage fully. Rust or paint build-up can stop them seating. Our page on impact door lock hardware covers hardware used on impact-rated doors, which has its own requirements.

Shutters, panels and their hardware

This guide focuses on door hardware, but shutters and storm panels often have locks, latches or fasteners of their own. Accordion and roll-down shutters usually have a lock or pin that holds them closed, and these can corrode or jam if not operated regularly. Test them at the start of the season, not when a storm is two days away.

Lubricate moving parts with a product suited to the material, and clear dirt and salt from tracks. If a shutter lock does not work, a technician can often repair or replace it, but a full shutter system is a job for a shutter or window contractor. We stay within what a locksmith can sensibly address, which is locks, latches and keys.

Keep track of keys for shutters and storm hardware. A shutter lock with a missing key is a problem when you need it most. Store spares in a known place and add them to your key log, as described in key control for families.

Keys, fobs and smart lock backups before a storm

Gather your keys before the storm, including spare keys for doors, gates, sheds, shutters, cars and any safes. Put them in a waterproof bag or case you can carry if you evacuate. Keep copies of important keys with someone you trust outside the area, if that makes sense for your household.

If you have a keypad or smart lock, check the batteries and write down your PINs somewhere secure that does not rely on your phone. Test the physical backup key. Power outages can last days, and phones run out of charge. A lock that relies on a connection to work may behave differently if power or internet is out. Read our smart lock guide for more.

Make sure your car keys and fobs are in good condition. If you are evacuating, a dead fob battery is an unwelcome surprise. Replace weak batteries and know where your spare is. If you have only one key for a vehicle, consider having a spare made before the season, since replacement during a storm period can take longer.

Securing the home when you evacuate

Before you leave, lock every door and check each one by trying it. Latch gates and close garage doors. If you use a lockbox, make sure you know the combination and that it is not visible. Take your key set with you. Tell a trusted person where you are going and who may check the property after the storm, if that is safe.

Do not leave a spare key in an obvious place on the assumption that a neighbor or a contractor might need it. A spare outside is a risk whether or not there is a storm. If you want someone to check the home, give them a key in person or arrange a lockbox with a combination that you can change afterward.

Remove valuables from areas that may flood or be exposed. If you have a safe, check that it is secured and think about whether it needs protection from water. A technician can advise on safe service, and our page on safe opening and service covers common questions. For all of this, plan around official evacuation guidance and never put yourself at risk for property.

After the storm: inspect before you trust

After a storm, a door can look fine and still be compromised. Wind pressure, flying debris and water can crack frames, bend bolts, loosen strike plates and swell wood. Before you trust a door, inspect it. Check that it opens and closes smoothly, that the bolt extends fully and that the frame and hinges show no cracks or movement.

Look for water damage around the door. Rot develops gradually, and wet frames can soften the wood that holds screws. Check for corrosion on the lock and the latch, especially if the door faced driving rain or salt spray. A lock that has been soaked may need cleaning or replacement, and electronic locks should be checked before you rely on them.

If the home was damaged, if a door was forced or if you are unsure of its condition, call and describe what you see. Our page on storm damaged lock repair explains typical repairs, and lockouts after a hurricane covers what to do if you cannot get in. Do not walk into a damaged building if you are concerned about safety, and call 911 for any emergency.

A before and after checklist

A short checklist keeps the work manageable. Do the checks in the quiet part of the season, and repeat the after-storm list whenever a significant storm has passed. Write notes as you go so that you can describe problems clearly if you call.

Before the season, check each exterior door for alignment, deadbolt throw, strike plate screws, hinge screws, latch operation and weatherstripping. Test sliders and French doors. Check gates and shutter hardware. Review batteries, key sets and backup access. Plan which doors would be priorities if a repair were needed.

After a storm, look at each door again, plus any gate or shutter lock that was in use. Note anything that has changed. If a door was exposed to water or impact, treat it as suspect until it has been checked. A short phone call can help you decide which problems need attention now and which can wait.

• Doors close evenly and latch without force
• Deadbolts extend fully into solid strike plates
• Hinge and strike screws are tight and long enough
• Sliders catch fully and run clean in the track
• Batteries, backup keys and PINs are ready
• After the storm: look for cracks, rot, bent bolts and corrosion

When to call a professional and what to expect

Call when a door will not latch, a bolt does not fully extend, a frame is cracked or soft, a lock is corroded or has been soaked, or a door has been forced or struck. Also call if you are not sure. A short description is often enough to decide whether a visit is needed. In busy periods after a storm, demand can be high, and we do not promise arrival windows.

A technician will check the door, the frame, the hardware and, if needed, the keys. They will explain what they see and what the options are. Quotes are given by phone, and larger jobs may need an on-site visit first. A service call charge applies and is explained on the phone before anyone is dispatched.

Have photos ready, along with a description of the door and what happened. If you are locked out, read lockout after a hurricane first. When you are ready to check your home's doors before the next storm, call and we will talk through what to look at.
