Rugs and floors and colours

Q: We have bought a condo in downtown Toronto. Our engineered “*****” hardwood floors are various colours where area rugs have been previously placed. Would your refinishing process be able to be used on this type of hardwood floor?

How much would it cost for a room approximately 10 feet wide by 20 feet long?

A: I would just leave the rugs off those areas so that they may “catch up” as to colour.
