How To Secure Your Garage

How To Secure Your Garage

Garage security is a big deal.

You keep thousands of dollars worth of tools in there, your car, and any personal belongings within it.

Maybe you have an attached garage and you’re worried about intruders using it as an entry point in your home.

Whatever your fear is, it’s justified. Those who don’t take home security seriously enough are the ones who eventually regret it.

Let’s prepare for the worst so we can enjoy the best; this is how you’re going to secure your garage against multiple threats.

Securing Your Gage From the Following Threats

Theft is a major concern. There are over one million home invasions in the United States every year, and the garage is often seen as the easiest way to enter a home.

Many people will put alarms and security systems on their bedroom windows or living room doors, but it’s common to disregard an attached garage.

You can install an alarm system that hooks up to your main home system.

That’s what you can do to catch and alert them, but other than that, you should be averting this problem with preventative measures.

Don’t leave your garage open for too long if it faces the main road or has visibility from traffic. Keep your tools in chests or cover the racks on the walls.

Don’t give any potentially wandering eyes a reason to ever break into your garage to steal tools or a vehicle.

On top of this, get a smart light bulb to randomize lighting in your garage when you’re not there.

It gives the illusion that you’re wandering around your home when you’re actually sleeping.


Fire damage is hard to protect against; you never know when it’s going to happen, or if it’s going to happen for that matter. However, there’s one serious way to combat fire if it were to start.

In-home ceiling-mounted sprinkler system, just like you see in schools and office buildings. They’re low maintenance and are hard to accidentally trip.

It’s very rare that any smoke coming off of tools that you’re using on bodywork will enact the detectors; it’s usually thick, black smoke that sets it off.

This is an investment, no doubt, but it’s a near surefire way to combat fire damage before it spreads.

This would account for items in your garage being on fire, but may only slow down an electric fire caused by wiring (which is something you can’t really prepare for outside of annual home inspections).

Smoke Damage

Smoke damage is easy to prevent against. It is categorized as a sedimentary layer of soot and/or ash that forms on the walls and ceiling of any structure as the result of used fuel.

If you use a torch-style heater in your garage, you might have a layer of soot.

What this does is create a bad odor and aesthetic. Due to the greasy feeling that aged smoke damage can have, it could accelerate a fire if one were to occur in your garage.

In short, do a dusting along with the ceiling and try to only use electric garage heaters from now on.


We’re going to get technical here for a minute. It’s time to bust out the elbow grease and get to work on this one.

You’re going to first go outside the entire perimeter of your garage and check for any weak points where the siding might be coming up or rotting away. Replace those.

Next, go along the interior of your garage and make an 18” tall wall of bricks, cemented to the concrete flooring.

Put this brick wall as close to the walls of your garage as possible. Cement the wall and finish it off.

If you have no insulation in your garage and the wall has pockets of framing behind it, feel free to pour concrete in there as well.

For the spot where your garage door goes, you can go along the edges and create rubber dams. Think of these as thresholds for the door edges to rest against, very tightly.

Position these properly and they won’t interfere with your garage door opening or closing.

For an extra effect, go along the entire base of your garage (including behind these rubber stops) with rubber sealant caulking to account for any cracks that may occur from the cold.

Excessive Cold

It sounds ridiculous, but extreme cold can do some serious damage to your garage and make is susceptible to further damage or intrusion in the future.

Excessive cold can damage the springs on your garage door opener. Small bits of metal like this can easily be contracted due to the cold and snap.

Springs, handles toolbox handles, any metal in the rafters of your garage, and so on. It can affect your tools, and contract the interior walls.

If you store your washer and dryer in the garage or any major appliances like a spare generator, they can be damaged fairly easily.

They’re not designed to handle extreme cold. Get this: whatever coolant is in your appliances can freeze. It sounds crazy, but it’s true.

Since metal conducts cold like there’s no tomorrow, it can actually amplify the actual temperature in the room and damage appliances.

Wild Animals

Winter comes, and wild animals look for a place to hide. Not all are hibernators.

Sure, you don’t have to worry about a winter mouse or two, but raccoons and coyotes might try to get in if the garage is warmer than the outdoors.

This one isn’t so simple. Even if you take good care of your home, the previous house owner likely fell into the pitfall that most homeowners do: neglecting your garage.

Do a perimeter check. Sweep the outdoors. Animals aren’t going to jump through windows or break siding; they’re going to look for a weak point to gain access from.

If they can detect heat coming out from some wood siding, they might be able to slip in or paw at it and see if it’s a viable spot.

Insulate the bottom three feet of your garage walls from the inside to prevent this, and check for any damage outside.

Hazardous Situations

Can Of Chemicals In Garage

Hazardous situations include anything that can cause bodily harm through falling, cutting yourself or chemicals that would either impact your breathing or singe your skin.

That’s not everything, but it’s basically something that isn’t an outside threat. Something that is easily preventable against.

This is where it’s important to keep a manifest of all chemicals that you use in your garage. It’s where you should have a first-aid kit at-the-ready.

Hazardous situations should be prepared for, but you should also try to optimize your space to avoid them in the first place.

Some rules of thumb to reduce hazardous situations include:

  • Storing chemicals in proper receptacles
  • Not running power cables along the floor (use a conduit)
  • Don’t leave sharp tools out that are not in your hand and immediately being used
  • Ensure plenty of walking space in between workbenches and storage containers
  • Keep falling hazards (tool chests, hanging racks) up against walls at all times

Go Fortify Your Ultimate Space

There are a lot of scenarios that you can imagine where your garage could be compromised—good thing we’ve accounted for them.
