Replacing a fogged-up or failing insulated glass unit (IGU) means carefully removing the old sealed pane, cleaning the frame, and installing a new double or triple glazed unit with fresh desiccant and edge seals. It's a specialized job because the insulating gas fill and low-e coatings must stay intact. Done right, it restores energy efficiency and clarity without replacing the entire window sash.
