How To Make Patio Doors More Secure

I’ve got a simple 5 point guide below on how to make patio doors more secure in your home.

Patio doors, by their very nature, are easy targets and a much easier way to access a property than through a window or through a traditional front door that has many more security features built in compared to a patio door.

For many homes, patio doors are the weak link.

And that’s because the design basis means they favour aesthetics over security; with the focus usually being on offering wide angled, unobstructed views of gardens from within the home itself.

Patio doors are also usually located at the rear of a property, which again is another weak point especially if you don’t have adequate outdoor security lighting or adequate side gate security.

Unfortunately, this makes patio doors more vulnerable to break ins and burglaries.

But here’s 5 things you can do to make your patio doors more secure and less prone to break ins.

1. Home Security Audit

If you are wondering how to make patio doors more secure, then looking at a specific thing like patio door security in isolation is entirely the wrong approach.

We need to look at the bigger picture before improving the security of your patio doors, and that means a brief audit and asking some simple questions.

I’ve got a much more in depth article here on how to improve the security of your home that covers 75 points, but for this article we will keep it simple and start with this list of things to do to make patio doors more secure by first, looking at the bigger picture:

  • If I came and stood outside your house, how easy would it be for me to get to a point where I was stood in front of your patio doors?
  • Can I walk straight off the street and stand in front of your patio doors without having to navigate physical barriers like locked gates or fences?
  • Physical barriers include fencing, gates, walls, hedges – would they stop someone entering the rear of your property, or at least, make it difficult for them?
  • Do you have any night lighting on that route to your patio doors, like on your driveway or down the side of your home? Night lighting includes always on lighting or motion detection lighting.
  • Do you have night lighting in and around the area where your patio doors are? This includes security lighting above your patio doors or motion detection lighting.

These are basic questions and basic principles of security, and the principle of these questions all surround the deterrent factor from the outset.

If I can simply walk off the street, and down the side of your house and into your back garden, the first thing you need to do is install some tall wooden gates or fencing, and some form of lighting.

As I always say, a physical barrier is a superb deterrent.

And that’s because an opportunist criminal will nearly always choose the path of least resistance. Walls, gates and fencing add resistance, so it’s well worth exploring the possibility of new gates or fencing – your local DIY store will be able to help with this.

The same goes for lighting – if external parts of your property are in darkness, then there is no deterrent present. It’s then a much more inviting prospect for someone who doesn’t want to be seen and who wants to use the cover of darkness to access areas of your property that you don’t want them to access.

I have this article here on how lighting can improve security around your property.

2. Lock the Door!

An easy way how to make patio doors more secure is to simply lock the door.

When you are not near your patio doors, close them and lock the door with the key or locking system.

A large proportion of burglaries and thefts are committed through open or unlocked doors, especially in summer months when doors are left unattended.

Sneak in burglaries are common in the UK in spring and summer months. All it takes is you to be in an upsatirs room for just a few minutes. Maybe you have been sat in the garden, and you nip to the upstairs bathroom without shutting the patio door.

Next thing, you return downstairs and at worse there is somebody there stealing your valuables, or someone has already been in and out of your home within seconds, stealing valuables before you’ve even realised.

Reduce the risk of this happeneing by simply shutting and locking patio doors when you are not near them.

3. Keys In The Door

When going out for day or going to bed, lock the door with the key, and remove the key from the lock.

Have a place in your house nearby your patio doors where you store your key, whether it is on a hook or on top of a counter or wherever – just make sure it is not in the lock.

Make sure everyone in your household knows this specific place so in the event of a fire it can be reached quickly and easily.

But why?

Having a key in the lock means that any would be burglar can simply smash a small piece of glass, for instance, nearest to the key, reach in and then simply unlock the patio door.

This same advice goes to any door or window with keys in the locks. Remove them, and it makes things harder.

4. Additional Locking Capabilities

There are some cheap but extremely effective aftermarket products you can purchase to make patio doors more secure and give you extra piece of mind. (Read also: Best Patio Door Handle Locks).

If you have a single, sliding patio door for example, an excellent product is a simple extendable brace or jammer (Read: What Is A Door Jammer?) which prevents the patio door from being slid open – whether it’s locked or not. Simply drop it into the rails in front of the non sliding portion, and you have an extra layer of protection.

  • RAPID DEPLOYMENT SECURITY DOOR BAR – A rapid deployment security bar that fits most sliding and hinged doors, to prevent forced entry.
  • PROTECT YOUR HOME – The security bar is ideal in an emergency to help delay a forced break in, allowing the victim time to alert the police. The door brace has a high tolerance, withstanding up to 250kg of force.

If you have the type of patio door that is a double door and the doors lock into each other, a simple solution for your circumstances is to buy a sliding bar lock.

These simply fix over your handles, essentially locking them together.

5. Alarms

Don’t dismiss an alarm system.

We are not talking about a full alarm system costing thousands of pounds, we are talking about an affordable DIY solution that will alarm when certain circumstances are met.

There’s two choices here. You can buy a contact alarm, or a vibration alarm.

A contact alarm will sound a loud, audible alert if the contacts are broken on the alarm. Not only does it alert you, neighbours or anybody in the vicinity, but an audible alarm will also deter the the person who is attempting to break in.
