Our house was built in 1905 - and the previous owners undid much of the detail & charm of an old house with bad workmanship and wood paneling. Our plan has been to do one project a year to slowly bring the house back to its original glory.

This year we are gutting the upstairs bedrooms - which includes removing some parquet floors from the original wood flooring (not sure the species).

Unfortunately they were glued down. Now the contractor tells us his "floor guy" says he cant sand it since there's glue - sight unseen.

What is the validity of this? We're open to removing the glue by hand with some putty-knives.
