Hello everyone I refer to the area framed by red line. I don't even know whether "curb" is the correct term but this is the "bump" area between living room and bed rooms. It is something like the baseline under the bed room doors. I am wondering if it can be replaced. I just bought a resale flat and generally the laminate floor condition is acceptable. The only tear and wear is the curb as shown in the picture. I don't know if this area can be replaced or repaired and where to find the replacement. Thank you.

Just for inquiry: won't the groove be dust/dirt collector and make cleaning more difficult?
