Philip Seymour Hoffman's estate has been slapped with a $US87,000 ($A94,130) lawsuit for flood damage.

Gene Hoffnagel and Anna Erdelyi claim water leaked from the Capote star's kitchen downstairs to their New York condominium and caused extensive damage to their walls and floors.

"They came home from vacation and found the floor was squishy under their feet," their lawyer Mark Seitelman says.

"The water went straight down. It wasn't gushing - just a steady leak and it did a lot of structural damage."

The couple's insurance agents covered the cost of replacing their items, but would not pay for the repairs that were needed, according to the New York Daily News.

Hoffnagel and Erdelyi claim the late actor assured them his insurance would cover the rest of the damage, which totals $87,329.60.

The couple is now seeking the money from Hoffman's executor and mother of his three children, Marianne O'Donnell.

Hoffman died in February of a drug overdose.
