I actually hired this work out. It's too high for me. The right side of the house is almost 45' from turf to peak of roof, so I passed.
I thought I could scaffold the house and do this myself, but working 40 hrs/wk really complicated things.
They spent 6 weeks painting. Two full weeks of prep work alone.
The colors we chose were pulled from a vintage/antique color selection card from Sherwin Williams. We also had a color consultant look at the colors we had selected to get her thoughts.
Being that we are in a historic district, all colors have to be approved by the committee before we can paint...
