Patio doors add light, space, and style to your home — but without the right security, they can also be a weak point.
In Newcastle, where break-ins and opportunistic theft still happen, it’s crucial that your patio doors are as secure as your front door.
At Windows and Doors Newcastle, we’ve helped countless homeowners upgrade their patio doors with better locks, stronger frames, and smarter security features. Whether you’ve just moved in or you’re upgrading your home, this guide will show you the best ways to secure your patio doors and protect what matters most.
Why Patio Doors Are a Common Target
Burglars look for easy access points. Patio doors, especially older sliding models, often have:
- Weak or outdated locks
- Large glass areas
- Poor visibility from the street
- Simple latches that are easy to force
They’re also typically at the back of the house — out of sight and less likely to attract attention during an attempted break-in.
That’s why modern security features and reinforced components are essential.
Common Types of Patio Doors (and Their Weak Points)
Before we dive into the best locks and upgrades, it helps to understand which type of patio door you have.
Sliding Patio Doors
These slide open on a track, often with a single latch lock. Older models are prone to being lifted out of the frame or forced open with basic tools.
French Doors
Two doors that open outwards or inwards from the centre. If not properly reinforced, the centre meeting point can be a vulnerability.
Bifold Doors
These stack to one side and offer wide, uninterrupted views. While modern bifolds are secure, cheap or poorly installed ones can have multiple weak points along the folding track.
Best Patio Door Locks and Security Features
Here’s what we recommend to secure your patio doors — based on what works best in Newcastle homes.
1. Multi-Point Locking Systems
Modern patio doors should have a multi-point locking system. This means the door locks at several points along the frame, not just at the handle.
This makes it much harder to pry the door open or force it from the top or bottom.
If your door still has a single central latch, it’s time to upgrade.
2. Anti-Lift Tracks and Reinforced Rails
Sliding doors can sometimes be lifted off their track from the outside.
To stop this:
- Add anti-lift blocks or screws to the top track
- Install reinforced steel rails that make lifting impossible
- Ensure the rollers and tracks are in good condition
At Windows and Doors Newcastle, we often install internal anti-lift devices as standard on all sliding patio doors.
3. Sash Jammers and Security Bolts
Sash jammers are small locks fitted to the inside of the door frame. When turned, they physically block the door from moving, even if the main lock is bypassed.
These work particularly well on French doors.
Security bolts, especially surface-mounted top and bottom bolts, are also an easy way to add extra resistance against forced entry.
4. Laminated or Toughened Glass
Glass is often seen as the weak spot — but modern safety glass is much harder to break.
- Toughened glass is heat-treated and resists impact
- Laminated glass holds together even when smashed, preventing easy entry
Both are great choices, but for extra security, laminated is best — it’s what we recommend for all low-level or accessible glass doors.
5. Security Bars or Door Braces (Optional)
For properties that need extra protection — such as ground floor flats or more remote homes — internal security bars or patio door braces can act as a strong secondary defence.
These are discreet, removable, and sit along the base of the door when not in use.
They’re also great if you’re away from home for extended periods.
6. Smart Locks and Alarms
Modern patio door locks can now be integrated with your home security system or smart home setup.
Some popular features include:
- Door sensors that alert you if the door is opened unexpectedly
- Keyless entry systems for secure access
- Integration with smart cameras or motion lights
If you’re installing new doors, ask about smart-compatible lock options.
Additional Tips for Keeping Patio Doors Secure
A few simple upgrades and habits can also go a long way.
Keep Tracks Clean
Dirt and debris in sliding door tracks can affect the locking mechanism, leaving doors partially ajar or easier to force.
Lock All Doors — Even When You’re Home
Many break-ins happen during the day. Always lock your patio doors, especially if you’re upstairs or in another room.
Add Motion-Activated Lights
Burglars hate being seen. Installing motion lights near your patio is a cheap and effective deterrent.
Use Curtains or Frosted Film
If burglars can see valuables through your doors, they’re more likely to target your home. Block the view with curtains or privacy window film.
Don’t Leave Keys in the Door
It might be convenient, but it’s also risky. Keep keys out of reach and out of sight from windows.
When to Upgrade Your Patio Doors
If your doors are more than 15 years old, have single-point locks, or show signs of wear, it may be time for a full replacement.
Modern patio doors offer:
- Better insulation
- Stronger locks
- Thicker, safer glass
- Improved noise reduction
At Windows and Doors Newcastle, we supply and install high-security sliding, French, and bifold patio doors — all with multi-point locks, anti-lift systems, and A-rated glass.
Summary: Secure Your View, Protect Your Home
Patio doors should be a feature you enjoy — not something you worry about.
By upgrading your locks, reinforcing the frames, and adding smart security, you can protect your home without sacrificing style or light.
