The sash has sunk and rubs against the frame, the handle turns slack, cold air comes through under the seal — know the feeling? In many cases this is sorted in 20–40 minutes with a proper adjustment, with no need to replace the window. uPVC windows are built for thousands of opening cycles, but with time the hardware works loose: hinges lose strength, clamping pressure falls, the sash moves by fractions of a millimetre — and then the draught starts. We adjust windows all over Warsaw: set winter and summer mode, get rid of draughts, fine-tune hinges and strike plates. If the seal is worn out — we replace it. Very often one visit is enough to get the window working almost like new again.

Adjustment is among the lowest-cost services. The final amount depends on how many sashes there are, the state of the hardware and how much needs doing. A basic switch to winter mode is the starting point. If hinges need tightening, strike plates need replacement or the seal needs changing — the cost goes up a bit. Still, even in harder cases it is only a small part of the price of replacing a window.
The price covers diagnostics, pressure setting, hinge tuning and a check of how the sash works. Seal replacement, strike plates or a new handle are charged separately, but these parts are cheap. Current prices below (compatible with Porta, VOX, Erkado and similar).

Adjustment is more than a quick twist with a hex key. The technician checks the whole system so the window works properly, not just stops the draught for a few days:

Plenty of people try to adjust windows themselves after watching online videos. Sometimes they manage it, but more often they make the problem worse:

Adjustment is clean and fast work, but a few simple things will make it go quicker:

A client in Wola said that in winter three living-room windows were letting in a clear draught, even though they had been fitted only four years earlier. Heating bills had gone up and it had become unpleasantly cold to sit near the radiator. During inspection we found that every cam was still set to summer mode — nobody had ever switched the windows to winter. The seals were in good shape, but the clamping pressure was very low.
We turned the cams to winter mode and tightened the lower hinges on two sashes — they had dropped slightly and were rubbing the frame. We lubricated all mechanisms with silicone spray. On one window a strike plate had shifted — we tightened it and fixed it in place. After the adjustment we checked the pressure with paper — the sheet held tight all around the perimeter. The whole job took about an hour for three windows. A week later the client called back and said the draughts were completely gone and the room felt much warmer. The lesson is simple: sometimes you do not need new windows to stop cold air — proper adjustment does the job.
We advise switching winter/summer mode twice a year. Full hinge and hardware adjustment — once every 2–3 years or whenever problems show up: draughts, a stiff handle, sash scraping.
If the timber window has tilt-and-turn hardware — yes, the adjustment is the same as for uPVC. Old timber windows without modern hardware cannot be adjusted — they need resealing or replacement.
Most often the fixing screws have loosened. Lift the decorative cover and tighten the two screws with a Phillips screwdriver. If that does not help, the handle mechanism is worn out and needs replacement.
In 90 % of cases — yes. The sash does not close because it has sagged, gone out of square or the strike plates have shifted. All of this is corrected by adjustment. If the hardware mechanism itself is damaged, the part will need replacing.
One sash — 15–20 minutes. A standard flat with 4–5 windows — about an hour. If seals need replacement, add 10–15 minutes per sash.
Not mandatory, but we recommend it. Winter mode increases clamping pressure and stops draughts. In summer it is better to reduce it — the seal lasts longer. Leaving winter mode on throughout the year flattens the rubber in 2–3 years.
Most likely the seal is worn out and no longer springs back after being compressed. Adjustment increases pressure, but if the rubber is finished the effect will only be temporary. The fix is seal replacement.

Window adjustment is done by technicians who handle window hardware every day — Roto, Maco, Siegenia, Winkhaus. We know how each system works and which keys are needed for it. We come with a full set of hex keys, screwdrivers, silicone lubricant and spare consumables (cams, strike plates, seals). We cover all of Warsaw — from Bielany to Mokotow. After adjustment the sash will close smoothly, the pressure will be even and the draught will disappear. If the problem comes back within a month, we return and fix it free of charge. Call or message us — we usually reply within an hour.
