Double glazing repair cost

Two of our windows have misted up between the panes. Can just the glass units be swapped rather than whole new windows, and what does that cost?

"Yes, absolutely. If the frames are still in good condition, there’s no need to replace the whole windows. We can simply replace the misted double glazed units.

Prices depend on the size and glass specification, but as a guide, replacement sealed units are typically around £120–£200 per unit supplied and fitted. Larger units or those requiring toughened, laminated, or decorative glass may cost more."

"Yes it can. That is the way it is done. We come out measure the glass and space bar to order a new complete unit"
