Glass unit replacement — choose a company and a technician
Has your glass unit cracked, broken or fogged up? On OKNA.ua you compare companies that replace glass units in PVC, wooden and aluminium windows across Ukraine — without replacing the whole window. Choose a company in the catalog on this page — by price, rating and lead time — and leave it a request. Measuring, removal of the old glass unit, manufacturing of a new one to your formula and installation are all done by the company you choose. Not sure which glass unit is fitted — add a photo of the window to the request, and the technician will determine the formula.
Need a new glass unit to order (rather than a replacement in an already installed window)? Go to the glass units section.
When you need to replace a glass unit
- Fogged-up glass unit (condensation inside). If moisture and "mist" appear between the panes, not on the surface, the unit's seal has failed. Wiping will not fix it — the glass unit needs replacing; the profile and hardware stay.
- Broken or cracked glass. The whole glass unit (the sealed cavity) is replaced, not a single pane — the cavity's seal cannot be restored otherwise.
- Cold window, a draught off the glass. Often it is enough to swap an old single-chamber unit for an energy-saving one (with i-glass, Low-E) or a double-chamber unit — warmer, without replacing the whole window.
- Street noise. A glass unit with a thicker outer pane or triplex noticeably cuts noise.
How glass unit replacement works
- Measuring. The chosen company's technician takes exact glass-unit dimensions and determines the formula (number of chambers, glass type).
- Manufacturing the new glass unit to the measured dimensions and chosen formula.
- Removing the old one and installing the new glass unit while preserving the cavity's seal; the window's profile, frame and hardware stay in place.
You do not need to take the sash to a workshop — the replacement is done on site, in your flat or house.
How much glass unit replacement costs
The cost is made of two parts: labour (measuring, removal, installation) and the new glass unit itself. Labour is approximately from UAH 500 (an indicative market price for replacement in Ukraine; the chosen company will quote the exact figure). The price of the glass unit depends on its formula — the number of chambers, the glass type (energy-saving, tempered, triplex) and the size — so companies calculate it individually. Compare the companies' offers on this page and choose the best one by price and lead time.

Questions and answers
How much does glass unit replacement cost?
The cost is made of two parts: labour (measuring, removal, installation) — approximately from UAH 500 at market prices in Ukraine — and the new glass unit itself, whose price depends on the formula, glass type and size. The exact figure is quoted by the chosen company after measuring. Choose a company in the catalog on OKNA.ua and leave a request — you will get an exact calculation for your window.
The glass unit has fogged up on the inside — can wiping fix it?
No. If condensation and "mist" appear between the panes, not on the surface, the glass unit's seal has failed. Wiping will not help — the glass unit needs replacing. Only the glass unit is replaced, while the window's profile, frame and hardware stay in place.
Can I replace just one broken pane rather than the whole glass unit?
No. A glass unit is a sealed cavity made of several panes, so when it is damaged the whole unit is replaced, not a single pane: the cavity's seal cannot be restored otherwise. The window's profile and hardware are not changed.
How long does glass unit replacement take?
The replacement itself on site is usually quick, but the overall lead time depends on manufacturing the new glass unit to your dimensions and on the technician's workload. The exact lead time is quoted by the chosen company when you place the request, along with the price; if the glass is broken, urgent replacement is possible.
Can a warmer glass unit be fitted during the replacement?
Yes. Instead of an old single-chamber unit you can fit an energy-saving one (with i-glass, Low-E) or a double-chamber unit — the window becomes warmer without replacing the profile. For quiet or safety, a unit with triplex is chosen. The chosen company will suggest the best option from your request.
Is the replacement done at my home, or do I need to bring the window in?
The replacement is done on site — in your flat or house; there is no need to take the sash to a workshop. The chosen company's technician comes out to measure, then returns with the finished glass unit for removal and installation.
