Help! Engineered hardwood.

6 years ago

Installing tongue in groove engineered hardwood floors over 3mm underlayment on original hardwood floors (I know, WHY? - because of cost to repair damage to orig hdwd) The issue is the total of underlayment and new floor is approx 1/16 higher than fireplace heart surround!
Should we sand orig hdwd, remove a few inches of underlayment or something else?
