Ditto with the above. Back to basics with housebreaking. Treat her like a brand new puppy in your house with no unsupervised freedom. Leaving her in the basement is probably frightening for her. For short periods away, a crate with some toys upstairs may be more suitable. Combine with with more compassion and an enzyme cleaner such as Nature's Miracle to get all the odors out and I'm sure you'll resolve this in no time.
How long did you have her before you moved into your new house, how old is she and what breed? Is she on a strict schedule? Remember dogs are just like kids LOL
