Balcony Door Modification for Locking with Cylinder Lock (FAB)

Balcony or terrace doors that can’t be locked from the outside can pose a security risk and cause inconvenience. At Window Solutions, we offer a practical modification of your existing balcony doors, allowing them to be locked with a standard FAB cylinder – similar to your main entrance door.

Customer Reviews

J
Janka, Smolenice

After several years, our windows started to let in drafts and wouldn’t close properly. The technicians from Window Solutions arrived quickly, adjusted everything, lubricated the fittings, and now the windows feel like new. Professional service at a fair price.

We were looking for shading for the south-facing side of our house and ended up taking the advice of Window Solutions. The blinds look great and work perfectly.

We have an insect screen with a small pet door, and it’s a great solution. We can finally ventilate the house without bugs flying in. It looks good and works even better.

Aurélia, Kolárovo

I really appreciated that the technician didn’t replace everything unnecessarily, but explained which seals could still be treated with impregnation. You can feel the difference after the service.

Simona M., Šurany

Our windows were difficult to close and in poor condition—we thought replacement would be necessary. But the technician from Window Solutions adjusted and lubricated them, and now everything works perfectly. I really appreciate their honest approach.

Very satisfied, fair pricing. I’ll definitely reach out again next year.

Frequently Asked Questions

  • It’s recommended to schedule maintenance at least once a year — ideally in autumn, before the heating season. Newer windows usually only require a basic check-up, while older ones may need more attention or adjustment.

  • Yes, if it’s a minor issue, such as lubricating the hardware (using machine oil or a special window lubricant) or tightening loose screws on the fittings or handle, you can handle it yourself. However, for more serious problems, it’s always best to contact a professional.

  • Seal gasket impregnation is a maintenance process where the gaskets are treated with a special product that restores their flexibility and extends their lifespan. This treatment helps maintain optimal window tightness and should be performed at least once a year—ideally in autumn, before the start of the heating season.

  • This type of blind requires regular maintenance—ideally using a duster or a soft, dry cloth. For heavier dirt, a damp cloth with a mild fabric cleaner can be used, although plain clean water is usually the safest optio

  • The average price ranges from a few dozen euros to several hundred euros, depending on factors such as the number of windows, the complexity of the service, and the materials required. Your Service Advisor will always provide an exact quote after the free inspection.

  • It is recommended once or twice a year, ideally in spring and autumn.

  • Yes, we can provide service even for older windows, regardless of the material they are made from.

  • Of course, it's entirely up to you whether you decide to proceed with the service after the inspection and price quote.

  • Yes, we can repair or replace components on horizontal blinds to restore full functionality. For more details, visit the Interior Shading Solutions section on our website.

  • If the blinds aren't heavily soiled, we recommend using a dry cloth to gently wipe the slats from top to bottom. For light dust buildup, a vacuum cleaner may be used occasionally—always on the lowest suction setting. In case of heavier dirt or grease, a soft cloth dampened with a mild detergent solution can be used to clean the surface.
