Typical Signs of Gasket Damage Recognizing the early caution indications can save house owners from pricey repair work later. Look for: Drafts-- an obvious drop in room temperature level near the window. Condensation-- wetness forming in between the glass panes, suggesting a broken seal. Noticeable cracks or spaces-- spaces in the rubber that show up to the naked eye. Water stains-- water marks on the wall or trim beneath the window. Increased energy expenses-- an unexpected spike in heating or cooling costs. If any of these signs appear, a more detailed evaluation of the gasket is called for.
