How to Fix a Peeling Door Sill Guard
A peeling sill guard usually means poor surface prep or heat failure. Fix it by cleaning the area, pressing firmly, or replacing the strip; a lifted edge collects dirt and looks worse than none.
Diagnose the cause
Lifted corners mean dust under the adhesive or summer heat; clean and re-press, or replace.
Replace if torn
Once a guard tears it will not re-stick; swap it for a fresh universal strip.
