We have a newer 2005 "Cardboard Colonial" as I call it, and the builder used particle board stairs (under carpet) for the main (L shaped) staircase. It's structurally sound, but due to wear and tear we really want to remove the carpet. Unfortunately, we aren't sure what we can do with the particle board stairs. If it were old pine treads, I could get creative - but particle board? Then what?

Does anyone know how difficult it is to change out the PB risers/treads? Or does anyone have experience with the stair "refacing" systems out there? Our hardwoods are maple downstairs and we'd like to match it without breaking the bank or losing the use of our stairs for weeks.
