What are the work hours for house painters?

Residential house painters usually work from 7:30am to 3:30pm. During the summers when it gets very hot, house painters sometimes start as early as 5:30 to avoid having to work in the hot sun during the noon/early afternoon hours.

Commercial house painters usually work the same hours. However, because commercial house painters often service businesses/offices/manufacturing plants, they cannot work there during normal business hours. In order to minimize disruption to customer flow/manufacturing processes/etc, commercial painters sometimes have to work during the night and on the weekends.

For example, Yaros Painting commercial division promises to service their commercial customers with "minimal disruptions to your customers, tenants, or business operations"
