回复：手指被窗户砸伤能向房产公司索赔吗？

A landlord only has a duty to maintain common area, and warn latent defects of the property. He also has a general duty to exercise reasonable standard of care if he takes on repair. He has no duty after the property is leased. Based on what you said "主要原因是
窗户老旧所导致的", the defect is latent so that he had no duty to warn or repair.

Even if he negligently repaired the window, he could still argue that you assumed the risk.

Your only chance is if the defect was not so obvious when you leased it and the landlord did not warn.
