A good window lock is essential for the security of your home. Just like doors, windows are one of the most commonly used entry points in burglaries — yet they are often overlooked when it comes to security.

Locksmith Lucas helps you install, repair or replace window locks — professionally, quickly and with a focus on maximum burglary protection. We work throughout Flanders and are usually on-site within 30 minutes.

Why window locks are important

Many break-ins don’t happen through the front door, but via windows on the garden or street side. The standard closing mechanism supplied with windows is rarely strong enough to resist forcing. With a solid window lock, you make it almost impossible for burglars to pry the window open with a screwdriver or crowbar.

Besides safety, a good window lock also improves the seal of the window, reducing draughts, noise and heat loss.

Types of window locks

There are several types of window locks, each with its own application and advantages. Our experienced locksmiths will gladly advise you which lock best suits your windows and your home.

1. Surface-mounted window lock

Mounted on the frame and easy to install. Ideal for outward-opening windows. Available with or without key.

2. Mortise window lock

Built into the frame for a stronger, more discreet locking. This system often locks the window at multiple points simultaneously.

3. Window bolts and latches

Practical, child-friendly solutions for smaller windows or tilt-and-turn windows. Available in lockable and non-lockable versions.

4. Security window lock (SKG-certified)

For maximum protection. These certified locks are tested for burglary resistance and offer the highest resistance against manipulation.

We work only with high-quality, certified locks that meet strict European safety standards (PKVW / SKG).

Tailored window security

Windows differ from house to house. Older wooden windows require a different approach than modern PVC or aluminium profiles. That’s why Locksmith Lucas always looks at the specific situation to determine the best solution.

We can also expand your window security with:

  • 🛡️ Hinge bolts and security hinges
  • 🔒 Security bars or lockable window stays
  • 📡 Magnetic contacts or motion sensors for extra security
  • 🔐 Anti-pull protection and multipoint locking

This way you get a complete solution that fits your home and your budget.

Have your window lock installed by a professional

Installing a window lock may look simple, but in practice it requires precision. Incorrect placement can mean the lock loses its burglary resistance or the window no longer closes properly.

Locksmith Lucas has more than ten years of experience installing, repairing and replacing window locks. We guarantee a clean finish and correct installation, so your window continues to function perfectly — and remains secure.
