Window mechanism replacement

Window mechanism replacement is appropriate when diagnostics confirms damage or wear in a specific component that cannot be restored effectively by adjustment or repair. A stiff handle, closing problem, rubbing sash or unusual noise does not automatically mean the hardware needs replacement.

We first identify the cause and the hardware system. If window adjustment or maintenance is enough, we do not recommend replacement unnecessarily. When a component is damaged or worn, we use a new, original part suitable for the identified system. Required parts are taken from stock or ordered from our suppliers.

Which symptoms call for hardware diagnostics?

• The handle spins without normal resistance, jams or does not operate the locking points – the cause may be the handle, gearbox or another mechanism component.
• The sash drops, rubs or changes position during opening – we check geometry, hinges, the stay and adjustment before deciding on replacement.
• The window does not close or lock correctly – we inspect sash position, strikers and perimeter hardware operation.
• A component has visible damage, excessive play or a break – diagnostics determines whether one part or a larger section needs replacement.
• Unusual noise or increased resistance appears – this may be related to adjustment, maintenance or wear; the symptom alone does not prove replacement is necessary.

What can window mechanism replacement include?

Handle or gearbox component replacement

If diagnostics confirms damage to the handle, gearbox or a related component, we identify the system and select the correct original part.

Hinge-side or stay components

Tilt or sash-guidance problems can have several causes. Before replacement we inspect geometry, adjustment and the load-bearing and guiding components.

Perimeter hardware components

The scope may include the gearbox, corner drives, rollers, locking components or other parts that transfer handle movement. We do not replace the complete perimeter hardware automatically; the required scope follows from the diagnosed fault and specific system.

Striker adjustment or replacement

Frame strikers work with the locking elements on the sash. We first inspect their position and condition; replacement is needed only when adjustment is insufficient or the component is damaged.

Why is hardware-system identification important?

Tilt-and-turn hardware is made up of coordinated components including gearboxes, corner drives, stays, hinges and locking points. Component design depends on the specific system and version, so we do not select parts by appearance alone.

We work with popular hardware systems including Roto, Winkhaus, MACO and SIEGENIA. Examples of recognised platforms include Roto NT/NX, Winkhaus activPilot, MACO MULTI-MATIC and SIEGENIA TITAN. The manufacturer name alone is not enough to order a part; before replacement we check markings, series and the configuration used in the actual window.

Can just one component always be replaced?

No. In many repairs an individual damaged component can be replaced, but with older or discontinued solutions the original part may no longer be available. After diagnostics we then determine whether replacing a larger hardware section or another repair scope is the safe solution. We do not install arbitrary substitutes simply because they appear to fit dimensionally.

How does the service work?

• Contact – call us or complete the form. We contact you within about 15 minutes.
• Free call-out and diagnostics – the technician checks the fault on site and identifies the hardware system.
• Scope and quote – we explain whether adjustment, repair or replacement is required and provide the exact cost before paid work begins.
• Repair or replacement – after approval, we carry out the agreed work. Most common faults are resolved during the first visit when diagnosis and availability of the correct parts allow.
• Functional check – after the work we check opening, tilting, closing, locking and handle operation for the functions provided by the window.
• Guarantee – completed work is covered by a written guarantee of up to 5 years; the exact period and scope depend on the service performed and components used.

How much does window mechanism replacement cost?

Service prices start from 50 PLN. The exact cost depends on the damaged component, hardware system, parts availability and required scope of work. Diagnostics and the technician call-out are free, and we provide the exact quote before paid work begins. Indicative prices are available on our pricing page.

How does our service work?

The service process is simple and transparent — six steps from first contact to warranty:

• Contact – fill in a short form or call us. We call back within approximately 15 minutes.
• Free on-site diagnostics – a technician arrives at the agreed time and assesses the condition on site.
• We explain the cause – we show you exactly what needs to be repaired.
• We present the cost – after diagnostics we provide an exact quote. No hidden fees.
• We carry out the repair – after your approval we complete the work, most often during the same visit.
• You verify the result – we test the outcome together. You receive a service report, a warranty on the work performed, and the manufacturer's warranty on original parts.
