We provide window repair, window service and door repair across the regions we serve in Poland. We specialise in hardware adjustment, gasket replacement, mechanism repair and glazing unit replacement – in both residential and commercial properties.

When does window repair make sense?
In many cases there is no need to replace the entire window. The fault may involve hardware, gaskets, the glazing unit or another component while the frame itself may still be suitable for repair.
If the condition of the structure allows it, repair can restore correct operation without the cost of replacing the entire window. The actual condition of the frame, hardware, gaskets and glazing unit matters more than age alone.
What problems do we solve?
Typical window and door problems we deal with include:
- window won't close or has to be forced shut
- window lets cold in – a draught around the closed sash
- handle is stiff or spins without resistance
- condensation between panes (failed glazing unit)
- balcony doors drooping or scraping the threshold
- window sticks – hard to open or close
- window squeaks when opening or closing
- worn or hardened gaskets
- window opens on its own or won't hold position
If you recognise one of these symptoms, the first step is to identify its cause. Only then can we determine whether adjustment, component repair or another solution is appropriate.
Window repair services
Our services cover PVC, wooden and aluminium windows. Typical repair work includes:
Window repair
We repair PVC, wooden and aluminium windows. Depending on the fault, the work may involve hardware, hinges, handles or locking mechanisms. If a specific original part is required, we first identify the component for the installed system and check availability through our suppliers. See window repair for more details.
Window adjustment
The scope of adjustment depends on the window construction and hardware system and may include sash position and compression at the adjustment points provided by the manufacturer. Window adjustment can restore correct operation without replacing parts when the problem is caused by alignment or compression.
Gasket replacement
Gaskets can lose elasticity, deform or become damaged over time. Gasket replacement can restore correct sealing when the source of the problem is the condition of a correctly matched gasket.
Glazing unit replacement
Persistent condensation or fogging inside an insulating glazing unit usually indicates loss of its seal. Glazing unit replacement allows the existing frame to remain in place when its condition is suitable.
Hardware and mechanism replacement
Scissor stays, handles and perimeter hardware wear over time. When a component is worn or damaged beyond what adjustment can correct, hardware or mechanism replacement may be the appropriate repair.
Window insulation
We select the scope of window sealing and insulation improvement after locating the source of the leak. The appropriate repair depends on where air is entering the construction.
Mechanism cleaning and lubrication
Cleaning, inspection and maintenance of accessible moving components should follow the requirements of the specific hardware system. Cleaning and lubrication can help keep moving hardware operating correctly; the exact maintenance method depends on the installed system.
Restoring frame geometry
Correction may be needed when a sash has moved out of alignment and begins to rub or no longer works correctly with the frame. The method used to restore the geometry depends on the window construction and hardware system.
Emergency opening
Help when a window or balcony door has jammed and cannot be opened. Emergency opening includes identifying the cause of the blockage and determining the appropriate repair.
Door repair services
We specialise in servicing balcony doors and PSK sliding doors.
Balcony door repair
Service of PVC and aluminium balcony doors: hardware, hinges, locks and gaskets. Balcony door repair may include sash adjustment when the door rubs against the threshold or no longer closes correctly; the exact repair depends on the diagnosed cause.
PSK sliding door repair
PSK sliding-door service includes diagnosis of the components responsible for sliding, locking and correct sash operation. The scope of PSK sliding-door repair depends on the installed system and the fault.
Balcony door adjustment
Depending on the installed hardware, adjustment may involve sash alignment and compression. Balcony door adjustment can restore correct closing when the problem is caused by alignment or compression; worn or damaged components require separate repair.
Door lock and hardware replacement
We replace worn locking mechanisms, handles and hardware components in the balcony and sliding doors we service. We select the original part for the specific system, configuration and dimensions, then check its availability through our suppliers before installation.
Brands we work with
We work with windows and doors of all brands. In many cases the repair concerns a specific component — such as hardware, a handle, hinge, gasket or glazing unit — so replacing the entire construction is not always necessary.
- VEKA, Salamander, Aluplast, Rehau – PVC profile systems we service.
- Drutex, Oknoplast, MS Więcbork – window manufacturers whose products we also service.
- Schüco, Aluprof – aluminium systems used in windows, doors and sliding constructions.
- Roto, Winkhaus, Maco, Siegenia, Geze, GU, Dr. Hahn – hardware and locking mechanism manufacturers whose systems we service.
We use only original manufacturer parts sourced through our suppliers. The specific component is selected for the manufacturer, system and configuration; before installation, we identify the correct part and check its availability.
How does it work?
The service process is simple and transparent – six steps from first contact to guarantee:
- Contact – fill in the short form or call us.
- Free call-out and diagnostics – the technician arrives at the agreed time with no call-out charge and inspects the window or door on site.
- We explain the diagnosis – we show you what the inspection found and what work we recommend.
- We show the cost – after diagnostics we present the exact repair cost. No hidden fees.
- We repair – once you approve, we carry out the agreed work.

How much does window or door repair cost?
The price depends on the type of fault, the hardware manufacturer and the scope of work. After diagnostics we present the exact repair cost. We only start work once you approve. In many cases, adjustment, sealing or repair of a specific component can solve the problem without replacing the entire construction.
You will find an indicative price list on a separate page. Book your free diagnostic visit – we will contact you to arrange a convenient time.
