is installing vinyl plank flooring a job i can do myself?

Click-lock vinyl plank is about as DIY friendly as flooring gets. Score with a utility knife, snap, click together. What decides how it turns out is the prep. The subfloor has to be flat (check the flatness tolerance in the instructions, high spots get sanded or ground down, dips filled), leave the expansion gap at the walls, and undercut the door frames so the planks slide under rather than trying to scribe round them. Stagger the end joints too.
