If the blinds inside your door window are getting hard to slide, the problem usually isn’t the door—it’s the glass insert. Over time, the double-pane unit can buckle around the slider, making it stiff.
Most homeowners think they need a whole new door, but the fix is simple: pop out the old glass panel and replace it. A trained handyman can do the job in about an hour.
Pro tip: Always have someone on the other side of the door when swapping the glass to prevent an accidental fall-through. Replacing just the window saves money, time, and keeps your door looking brand new.
