Window Sealing Warsaw — Draught-Proofing, Adjustment & Prices

Cold air getting in through shut windows, moisture on the glass, or a draught you notice when passing the balcony door — all this points to worn seals or hardware that needs setting up again. We do window sealing in Warsaw and window adjustment every day, so below is what the job includes and what you can expect to pay.

Window Seal Replacement Warsaw — Current Prices

The price depends on how many windows there are, what seal profile is needed, and whether the hardware needs adjustment as well. Below you can see our rates for window and door sealing in Warsaw.

How We Draught-Proof Windows — Step by Step

Window Adjustment Warsaw — Our Process

1. Inspection. We open every window and check a few things: Is the seal split or compressed flat? Does the frame shut evenly? Do the hinges need tightening?
2. Hardware adjustment. With a hex key and dedicated tools, we set the closing pressure (compression), tilt position, and hinge alignment. In many cases this alone gets rid of the draught.
3. Seal replacement. The old rubber seal comes out, the groove is cleaned, and a new EPDM seal is pressed in along the entire sash perimeter.
4. Balcony door adjustment. We do balcony doors the same way — over time they drop and stop closing tightly. We raise, align, and tighten them.
5. Test. We close the window and do a paper test (a strip of paper placed in the closed sash should hold when pulled). Each window is checked one by one.

Common Window Sealing Mistakes

• Using foam tape instead of proper seals. Self-adhesive foam from a DIY shop lasts only a few months, then gets squashed flat. EPDM rubber seals hold up for years.
• Only sealing without adjusting. Fresh seals fitted to misaligned hardware get compressed unevenly and wear out quickly. Adjustment should come first.
• Ignoring the bottom edge. Draughts often start near the sill, where the seal meets the frame. We inspect every edge, not only the sides.
• Forgetting ventilation. If everything is sealed too tightly and there’s no trickle vent or regular airing, you end up with condensation and mould. We explain how to keep the right balance.
• Not servicing annually. Windows need adjustment and lubrication once a year — best done before winter. That helps avoid bigger trouble later on.

What to Prepare Before the Handyman Arrives

Window Seal Warsaw — Your Checklist

• Count how many windows and balcony doors need work — that helps us estimate materials and time.
• Make a note of which windows let in the most draught — we’ll begin with those.
• Remove plants and other items from the windowsills so we can open each sash fully.
• Check whether your windows are PVC, wood, or aluminium — the seal profiles are different.
• If the windows are very old (20+ years), think about whether full window repair or replacement makes more sense.

Real Example — Draught-Proofing a Flat in Ursynów

A couple in Ursynów said the rooms felt cold even with the heating turned up fully. We checked 6 PVC windows and one balcony door. Four windows had flattened seals, and the balcony door had dropped by 3mm — enough for cold air to come in. We replaced all seals, adjusted the balcony door hinges, and increased the compression on every window. All units passed the paper test. The client said the improvement was clear that same evening. Total time: about 2.5 hours.

FAQ — Window Sealing in Warsaw

How long does window sealing take?

One standard window: 15–25 minutes (seal replacement + adjustment). A whole flat with 6–8 windows takes 2–3 hours.

Is it worth sealing old wooden windows?

If the frames are still in decent condition — yes, sealing cuts draughts and heating bills quite a lot. If the wood is rotting, replacement makes more sense.

Can you also adjust a balcony door?

Absolutely — balcony doors use the same tilt-and-turn hardware as windows. We set them up together with the windows during one visit.

When is the best time to seal windows?

Before winter — best between September and November. But we do this all year round. Spring also works well, because you can properly check the airtightness.
