Window repair and adjustment in Warsaw — when to call a professional

A window that doesn’t shut properly, draughts coming from under the seal, a loose or stuck handle — these are problems we see on every second window after 5–7 years of use. In most cases, the fix is just a hardware adjustment that takes 15–20 minutes, with no need to replace the whole window. We work all over Warsaw — from Ursynów to Bielany, and we come equipped with a full set of keys and spare parts.

How much does it cost and what affects the price

Window adjustment — from 30 zł per sash. Seal replacement — from 25 zł per running metre. Hardware repair, handle replacement, sash realignment — from 150 zł. Roller shutter or blind fitting — from 200 zł. The final cost depends on the window type (PVC, wood, aluminium), the number of sashes, and the state of the hardware. Minor fixings are included. Seals, handles, and hardware parts are charged separately if they need replacing.

How the on-site work goes

1. You explain the issue over the phone — draughts, won’t close, squeaking.
2. The technician checks what type of window it is (PVC, wood) and how many sashes there are.
3. We set a time — often the same day or the following day.
4. On site, the technician inspects each sash: pressure, alignment, and seal condition.
5. Adjusts the hardware with hex keys and changes parts if needed.
6. Checks the result — the sash should shut tightly without force.
7. Gives a few maintenance tips: how to lubricate the hardware and look after the seals.

Common customer mistakes (and how to avoid them)

• Putting off adjustment — the sash drops, damages the seal, and a 30 zł job becomes 300.
• Trying to adjust the window without knowing how the hardware works — the pressure gets thrown off and the window stops closing.
• Covering gaps with adhesive tape for winter instead of changing the seal — moisture collects underneath and mould appears.
• Never oiling the hardware — the mechanism seizes up and the handle snaps.
• Buying a seal with the wrong profile — it won’t sit in the groove and comes out within a month.
• Replacing the whole window when a 150–400 zł hardware replacement would have solved it.

What to prepare before the technician arrives

• Clear plants, vases, and small items from the windowsill.
• Make sure there is easy access to the window — move furniture if it blocks the sash.
• If you know the hardware brand (Roto, Maco, Siegenia) — tell the technician beforehand.
• Describe the fault as clearly as you can: which sash it is, and in what position it gets stuck.
• Check whether the other windows have problems too — it may make sense to adjust them all in one visit.
• If the window is on a high floor with no outside access — let us know in advance.
• Send access details: intercom code, key, parking information.
• If you need a handle replaced — you can purchase one beforehand (standard: 7×7 mm spindle, 35 mm length).

A real case from Warsaw

A client in Mokotów called about strong draughts coming through her balcony door in winter. Neighbours had advised her to replace the whole door. When we checked it, we found the sash had dropped 4 mm because the hinges were loose, and the seal had gone hard and started cracking. The technician tightened the top and bottom hinges, switched the pressure cams to winter mode, and replaced the seal around the entire perimeter. The work took 40 minutes. After the adjustment, a sheet of paper trapped between the sash and frame could not be pulled out — the pressure was exactly right. The client confirmed the draught was completely gone. Instead of replacing the door for 3,000+ zł, the repair cost 250 zł (compatible with Porta, VOX, Erkado and similar).

Frequently asked questions

How can I tell my window needs adjustment?

The sash is hard to close, the handle turns with resistance, you feel draughts from under the seal, or the window won’t stay in the tilt position.

Can wooden windows be adjusted?

Yes, if they have modern hardware. Older wooden windows without tilt-and-turn mechanisms are adjusted in a different way — an inspection is required.

How often should windows be adjusted?

It’s best to do it once a year — tighten the pressure before winter and ease it off in spring.

Is the seal replaced on the spot?

Yes, the technician removes the old seal and fits a new one into the same groove. It takes 10–15 minutes per sash.

How much does it cost to adjust all windows in an apartment?

It depends on how many sashes there are. A standard 3-room flat with 6–8 sashes costs 200–350 zł.

Do you work with roof windows (Velux, Fakro)?

Yes, we adjust them and replace seals. For glazing replacement — please enquire.
