Everything you need to know about our window and door repair services
Yes, the initial diagnostics and our technician's visit to assess the work are completely free. No hidden costs and no obligations. If you decide to proceed with the service, the technician will provide a clear quote on site, explain all the details, and if needed – can start work immediately and complete the repair during the same visit.
Absolutely! We provide a warranty for both the services performed and the materials used – in accordance with applicable regulations.
The cost of window repair depends on the type of fault and the scope of work. Our technician visits free of charge, assesses the situation on site and provides a precise quote before starting work. Most minor issues are fixed during the first visit. You can see our indicative prices on the pricing page.
Booking a free diagnostics is very simple. Just call our contact number or fill in the registration form – either way it only takes a few minutes.
In most cases, repair is sufficient: replacing seals or hardware, sealing, adjustment, cleaning and lubricating the mechanisms. This is a much cheaper solution than installing new windows.
Repair is usually less expensive — there's no need to buy a new window, remove the old one, dispose of it, or carry out finishing work after installing a new structure. Most window faults (gaskets, hardware, adjustment) can be fixed for a fraction of the cost of a full replacement.
We service windows from all major manufacturers, including: Rehau, Veka, KBE, Schuco, Salamander, Aluplast and many others. Our technicians undergo training on the specific mechanisms of each manufacturer.
Yes, we accept payment cards, BLIK, bank transfers and cash. Payment is settled after the work has been completed; on request we issue an invoice.
Yes, we provide services all year round. During winter, we carry out window servicing using special methods to avoid cooling down the rooms and ensure maximum comfort.

Lubricated the window hardware, only for the window to feel stiff again later? More lubricant is not always the answer. Dirt, product choice, sash alignment and the condition of the mechanism are all worth checking.
A window that is hard to close, draughty or fogged between the panes does not automatically need replacing. But the fact that another repair is technically possible does not always make it the best decision. The key is to identify where the cause lies, what can be repaired effectively and what result that repair will actually deliver.
How should window service work from the first report to completion? See what to provide before the visit, what can be estimated remotely, how diagnosis works and when the final scope and price should be agreed.
Ten years of use does not mean a PVC window has to be replaced or automatically repaired. It is a useful point to assess the seals, hardware, drainage, insulated glass unit and the connection between the window and reveal. The condition of the specific construction, not age alone, should determine the work.
Coastal conditions can increase the load on some window components, but an address in Gdańsk or Gdynia does not by itself determine service needs. What matters is the building's actual exposure, the window system and the condition of its components.
When a window becomes hard to close, starts leaking air or the handle stops working properly, a list of local services does not tell you which one to choose. Learn what to clarify before a visit in Katowice and how to compare offers by scope, not price alone.
“Winter mode” is a common name for increasing sash compression in hardware systems that allow this adjustment. It is not a universal switch found in every window, nor something that must be changed twice a year. This guide explains how to identify adjustable compression, when a correction makes sense, and when a draught has a different cause.
A draught, a change in handle operation, sash rubbing or moisture are signs that a window is operating differently. They do not automatically point to one cause. We explain what to observe before a visit and how professional window diagnostics work.
A window that rubs, is harder to close, feels draughty or shows moisture does not automatically tell you what needs to be repaired. This guide explains when adjustment may be enough, when a specific component needs repair or replacement, and when replacing the whole window is worth considering.
Compare window repair and full replacement by looking at the complete cost and the result each option delivers. See what to include in the calculation, what remains after repair and when replacement offers a meaningful additional benefit.
Preparing windows for winter does not mean automatically adjusting every sash. It is more useful to check how the window closes, inspect the gaskets and hardware, make sure drainage remains clear and identify any areas where air leakage can be felt. This guide explains what you can safely check yourself, what not to adjust just because winter is approaching, and when professional diagnosis is the better option.
Water or condensation around a roof window does not always mean the same problem. What matters is where moisture appears, the condition of the window itself and its connection to the roof. This guide explains how to distinguish these situations and when a more detailed diagnosis is needed.
People often start thinking about trickle vents after window replacement when condensation, damp or a stuffy feeling appears. A vent does not solve every ventilation problem, though. Its job is to provide controlled air supply, so the way the whole dwelling is ventilated should be assessed before installation.
Do windows need annual service before the heating season? Not always. See which symptoms should not wait until autumn, what cold weather may reveal and when the season is only a reminder to inspect.
Does the door scrape the threshold, need an extra push to close or become hard to lock? Similar symptoms can have different causes. One of the most useful clues is the exact point at which resistance appears.
If a window has become harder to open, sticks or rubs against the frame, the first step is to identify when the resistance appears. The cause may lie in the hardware, sash setting or geometry, or — for timber windows — dimensional changes in the wood.
Fogging between panes is not the same as condensation on the glass surface. Learn when replacing the sealed glass unit is the typical solution, how a replacement is specified and what affects cost.
Online it is easy to find videos in which "anyone can adjust their own window". Some of that advice makes sense; some can generate a second, more serious problem. This guide shows where the line of safe DIY on a window really runs.
Not every problem felt through a window handle is caused by the handle itself. Learn how to distinguish a handle fault from a hardware problem, choose a compatible replacement and change it safely.
Does the handle turn freely while the window does not respond? This does not automatically mean the handle itself is broken. The fault may be in the handle, its connection to the mechanism or the hardware. See what you can observe without dismantling the window and why replacing the handle at random may not solve the problem.
PVC window adjustment may involve correcting sash position and settings that affect how it works with the frame. The adjustment depends on the hardware system and the symptom, so the mechanism and correct adjustment point should be identified first.
For a business, the repair itself is only part of a larger window-service job. With many windows, the reports need to be organised, priorities set, access planned and documentation agreed. See what to prepare before the first visit and when ongoing service terms are useful.
A window can squeak while opening, closing or operating the handle, and the source is not always the same. Before applying lubricant or attempting an adjustment, check when the sound occurs and where it comes from. This guide explains what you can inspect safely yourself and when adjustment or repair is the better next step.
Water appearing around a window does not necessarily mean the window itself is damaged. Possible sources include the frame-to-wall connection, drainage, the insulated glass unit or the way the sash closes. Where moisture appears can help narrow the possibilities, but it does not confirm the cause on its own.
Damp and mould around a window do not automatically mean a fault in the window itself. Indoor conditions, ventilation, surface temperature, airtightness and the condition of the window-to-building connection can all matter. These possibilities should be separated before deciding on a repair.
Windows in old tenement buildings need to be assessed from two sides: technical and formal. The condition of the timber, hardware and glazing shows what may be repairable or restorable, while the protection status of the specific building helps determine what requirements should be checked before a larger intervention.
Aluminium windows are durable, but their seals, hardware, insulated glass units and other components can still require service. A stiffer handle, draught, condensation or an unusual sound do not automatically point to one cause. This guide explains what is worth checking before deciding on repair.
HST doors can move large, heavy sashes with relatively little user effort, but one symptom rarely points to one specific part. Heavier movement, handle resistance, scraping or leakage should be linked to the moment in the operating cycle when the problem appears. See what you can safely check yourself and when system-specific diagnosis is needed.
Window hardware problems do not always mean replacing the entire mechanism. In some cases adjustment is enough; in others, a specific component must be replaced. The key is distinguishing misalignment from wear or physical damage and correctly identifying the hardware system.
Feeling cold near a window does not always mean air leakage. Learn how to distinguish a real draught from cold glass and match the repair to the actual cause.
Wooden windows need attention, but not according to one rigid schedule. The condition of the coating, wood, hardware and seals — and where a change appears — tells you far more than the calendar alone.
A PVC window has started working differently? Follow a short step-by-step inspection of the sash, handle, seal, drainage, glazing and hardware markings, then choose the right next step.
Coastal conditions can matter for hardware, airtightness and the way some window problems show up, but they do not create a separate diagnosis. See what to watch for in Gdańsk, Gdynia and Sopot, what not to adjust too quickly, and when service is needed.
Dust and deposits do not automatically mean a window fault. Clean first, reassess the seals and hardware, and see when a remaining symptom requires service in Silesia.
Many flats in Łódź still have PVC windows installed well over a decade ago. Age alone does not decide whether replacement is needed. The condition of the frame, sash, hardware, seals and glass unit — and whether parts can still be matched to the older system — matter far more.
A window draught does not automatically mean a worn gasket or the need to replace the whole window. The first step is to identify where air movement occurs and whether the issue involves the sash, gasket, hardware, installation joint or another part of the construction.
Moisture on glass can look similar even when the causes are very different. The key is to establish where it appears: on the room side, on the outside surface or between the panes. That is the first step in separating surface condensation from a problem with the insulated glass unit itself.
Spring is a useful time to check how windows are operating after the heating season. This does not mean every sash needs adjustment. A short inspection, manufacturer-recommended maintenance and attention to specific symptoms are usually the right starting point. This guide explains what you can check yourself, when adjustment makes sense and when professional help is appropriate.
Many large-panel buildings still have windows installed during earlier renovations and upgrades. Their age alone does not determine replacement. Diagnosis should assess the condition of the window itself separately from its connection to the reveal, because similar symptoms can have different causes.
Advice such as “once a year” or “every two years” is only a simplification. The need for adjustment depends on the specific window, its hardware system and how it actually operates.
A leak around a roof window does not automatically mean a failed seal, and hard opening does not point to one component by itself. Learn how to recognise the main symptoms, what can be checked safely from inside, and when diagnosis needs service or roof access.
During smog episodes in Kraków, residents face a practical problem: homes still need air exchange, but opening windows when outdoor pollution is high increases exposure to outside air. This guide explains when to limit window airing, the role of trickle vents, what filtration can realistically do, and when the problem lies with the window rather than the building's ventilation.
Does your balcony door rub against the threshold, need lifting to close, or work with noticeable resistance? These symptoms may result from sash position, hardware setting, geometry or a damaged component. See when adjustment is enough and when repair is needed.
In Warsaw, building age alone does not identify the window or the fault. See how the history of window replacement, construction, installation and previous repairs changes the diagnostic approach.
Two windows with the same apparent symptom can require very different repairs. Here is what actually determines the cost and how to understand a service quote.
A rubbing sash, damaged coating or soft wood does not automatically mean the window needs replacing. Learn how to distinguish hardware issues from changes in the timber, what not to repair too quickly, and when the condition of the whole window makes replacement worth considering.
A draught around a closed window does not automatically point to one cause. The problem may involve the gasket, sash-to-frame contact or the frame-to-wall joint. First identify where air movement is actually occurring.
Aluminium window adjustment depends on the specific profile and hardware system. The construction and symptom should be identified first, then it can be determined whether the problem is within the adjustment range or requires repair.
A closing problem does not automatically mean the whole window needs replacement. Depending on the cause, sash adjustment, hardware repair or replacement of a damaged component may be needed. First identify what is preventing the window from closing correctly.
Mist or droplets visible between the panes are a different problem from condensation on the glass surface. If moisture is genuinely inside the sealed glass unit, the unit and the existing window construction should be checked to determine the appropriate solution. This does not always mean replacing the whole window.
A simple sash adjustment does not need the same contractor-selection process as a larger repair or full window replacement. Learn what to clarify before the visit, what a useful quote should explain and which question to ask about price changes.
There is no single interval after which every window must be adjusted. Inspection and maintenance may follow the manufacturer's schedule, while adjustment is needed when the window setting actually requires correction.
