Growing up my family often did a yearly house blessing. The parish priest did yearly rounds blessing the parish houses. In USA, it seems like the house is only blessed once before moving in and never blessed again. My parents especially liked getting house blessed in January starting the new year with a new clean blessed home.
So when I came across this Epiphany House Blessing tradition few years ago, I was very excited. It is very simple and easy. We use the prayers from Holy Heroes, found here. We got our chalk blessed after Sunday mass and brought back holy water from church. We all gathered by our house entry ways and prayed together. My husband led the prayers and we went through all our rooms with holy water saying prayers of blessings for each room. It was so wonderful and a great tradition for epiphany.
