The Witch in the Window (2018) on Netflix

Plot summary

Twelve-year-old Finn comes with his father Simon to a farmhouse in rural Vermont, where the two of them plan to make repairs. A woman keeps appearing in the windows, an ugly and malicious figure. She is Lydia, the spirit of a former owner, and she wants the newcomers gone from the property. Father and son do not pay her much attention at first and go on with their work, yet each repair they complete leaves her stronger than she was before. A local tells them that Lydia lived in that house years ago with her husband and her son, and that both of them died mysteriously.
