To begin with, “to renew” regarding a house means to “to restore to a new or fresh condition”. With that in mind, “to spruce up” means to make minor changes. It can be said about things like buildings, parks, other places, and even about one’s physical appearance.
Additionally, “to get up” is not something that I have heard regarding a restoring a house. I live on the West Coast of the US; fdmaxey lives in the southern part of the US. Where he lives, people may use the that verb in that way. In other words, it could be based upon the region where one lives. Generally, it means “to arise from bed; to climb; to dress; to find within oneself; or to act as the creator of something”. These then would not be related to restoring a house, using these meanings.
“To renovate” also means the same as “to renew”. One can fix up, restore, repair, or renew the condition of a car, a building/structure, etc. This may involve minor or major changes. This is not used about the a person’s physical appearance.
Lastly, “to decorate” simply means to place decorations somewhere. These decorations may be inside a structure like a house, or they be placed outside in the front yard. Plus, you can decorate a Christmas tree for Christmas or decorate a cake.
As you can see, some of those verbs can be related to more than renewing or restoring a home/building.
