I just moved in with my beautiful girlfriend to a condo in DC, and we were going to replace the carpeting
in our place with hard wood floors. When we tore up the carpet, however, we found some beautiful
square parquet tiles (maybe 6” x 6”). Most of the tiles are still in very good condition, however some have received water damage. Here are some pictures.

As you can see, it seems the previous owners made a “moat” of filler, and then replaced some tiles near the door. They then tried to use tack strips to aid the process.
My question, is can we simply replace the tiles that are mucked up? May there be other problems beneath the tiles we may not see?
Essentially, what's the best way to proceed to come out with some nice looking floors. Try to salvage this parquet? Lay a floating engineered floor above? Or rip it all up and start from scratch, dealing with hardwood over a concrete slab?

By your pics, it looks like most damage is by radiator.

Get a floor finisher/contractor in to inspect and give u an estimate if a repair can be made or just having the floors refinished.

The staples and tackless are easily removed. If water damage is not to deep, sanding and refinishing would be the way to go.
