By the 1900s, the Jackson Homestead began using municipal water rather from their indoor well. Under the direction of Louise Keith, William's granddaughter, major renovations were carried out. Modern plumbing was installed in the bathroom and kitchen, all of which were connected to the city sewers. Wooden ceiling beams were reinforced with iron braces and seventy-six new panels of glass were installed. The interior of the house was repainted, and the exterior of the house was painted white for the first time.
