Cold air coming through closed windows, condensation on the glass, or a draught you can feel when you walk past the balcony door — these are signs your seals have worn out or the hardware needs adjusting. We handle window sealing in Warsaw and window adjustment daily, so here’s what the service involves and what it costs.

Window Seal Replacement Warsaw — Current Prices

The cost depends on the number of windows, seal type, and whether the hardware also needs tuning. Below are our rates for window and door sealing services in Warsaw.

Replacement seals are included in the sealing price. If the window mechanism needs deeper repair (broken hinge, cracked glass unit), that’s quoted separately.

How We Draught-Proof Windows — Step by Step

Window Adjustment Warsaw — Our Process

1. Inspection. We open each window and check: Is the seal cracked or flattened? Is the frame closing flush? Do the hinges need tightening?
2. Hardware adjustment. Using a hex key and special tools, we adjust the closing pressure (compression), tilt alignment, and hinge position. This alone often eliminates draughts.
3. Seal replacement. Old rubber seal stripped out, the groove cleaned, new EPDM seal pressed in around the full perimeter of the sash.
4. Balcony door adjustment. The same process applies to balcony doors — they sag over time and stop sealing properly. We lift, align, and tighten.
5. Test. Window closed, paper test performed (a strip of paper held in the closed sash should resist when pulled). Every window tested individually.

Common Window Sealing Mistakes

• Using foam tape instead of proper seals. Self-adhesive foam from a DIY store lasts a few months, then flattens. EPDM rubber seals last years.
• Only sealing without adjusting. New seals on misaligned hardware will compress unevenly and wear out fast. Always adjust first.
• Ignoring the bottom edge. Draughts often come from the sill area where the seal meets the frame. We check every edge, not just the sides.
• Forgetting ventilation. Sealing everything too tightly without a trickle vent or regular airing leads to condensation and mould. We advise on the right balance.
• Not servicing annually. Windows should be adjusted and lubricated once a year — before winter is ideal. Prevents bigger problems down the line.

What to Prepare Before the Handyman Arrives

Window Seal Warsaw — Your Checklist

• Count the windows and balcony doors that need attention — helps us estimate time and materials.
• Note which windows draught the most — we’ll start with those.
• Clear windowsills of plants and objects so we can fully open each sash.
• Check if your windows are PVC, wood, or aluminium — seal profiles differ.
• If windows are very old (20+ years), consider whether full window repair or replacement is a better investment.

Real Example — Draught-Proofing a Flat in Ursynów

A couple in Ursynów complained about cold rooms despite the heating running full blast. We inspected 6 PVC windows and one balcony door. Four windows had flattened seals, and the balcony door had sagged 3mm — enough to let cold air through. We replaced all seals, adjusted the balcony door hinges, and tightened the compression on every window. The paper test passed on all units. The client reported a noticeable difference the 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 full flat with 6–8 windows takes 2–3 hours.

Is it worth sealing old wooden windows?

If the frames are in decent shape — yes, sealing significantly reduces draughts and heating costs. If the wood is rotting, replacement is better.

Can you also adjust a balcony door?

Absolutely — balcony doors use the same tilt-and-turn hardware as windows. We adjust them alongside windows in one visit.

When is the best time to seal windows?

Before winter — ideally September to November. But we do it year-round. Spring is a good time too, since you can properly test the airtightness.
