Window Mechanism Replacement
When window hardware parts become excessively worn or damaged, cleaning or lubrication is no longer effective – in such cases, window mechanism replacement is essential. This service fully restores the functionality, airtightness, and reliability of your windows, ensuring long-lasting results and smooth everyday operation.
When is mechanism replacement necessary?
Replacement is needed when the following signs appear:
- window does not close or lock properly;
- handle sticks, is too hard to move, or doesn't move at all;
- hinges are broken or deformed;
- window has lost its airtightness and adjustment does not help;
- hardware parts are rusted or non-functional.
In these situations, repair or lubrication will not resolve the issue – the best solution is to replace worn mechanisms with new ones matched to your specific window type and manufacturer.
How is window mechanism replacement performed?
- Free diagnostics. A technician assesses the hardware condition, determines the severity of damage, and recommends the most suitable solution.
- Removal of old mechanisms. Worn, rusted, or deformed parts are removed.
- Installation of new mechanisms. New original or equivalent hardware parts are installed, ensuring smooth operation.
- Lubrication and testing. New mechanisms are lubricated with professional products and window airtightness and operation are verified.
Which mechanisms are replaced?
Window mechanisms include multiple components responsible for proper window operation, airtightness, and security. We replace all main hardware parts, including PVC window mechanisms commonly used in residential and commercial buildings:
- Window hinges
- Handles
- Opening and locking mechanisms
- Fixators and corner elements
- Opening limiters and safety mechanisms.
Window mechanism replacement services are provided for all window and door types, including balcony and terrace systems. All new mechanisms are selected according to the specific manufacturer, profile, and window type to ensure precise fit and long-lasting operation.
Why is timely replacement of damaged mechanisms important?
Prolonged use of damaged or sticking mechanisms can damage the entire window frame or glass unit. Timely mechanism replacement helps:
- avoid more expensive repairs in the future;
- restore airtightness and reliability;
- ensure easy and smooth operation;
- extend the entire structure's service life.
Trust window mechanism replacement to professionals – our technician will visit, assess the condition, and ensure your windows work like new again.
