The size of your house, the state of the outside, the weather, and the kind of paint you choose will all affect how long it takes to do an exterior painting job in Wheaton. While a simple job takes three to four days, a large one may take a week or more. To restore loose or broken siding or apply primer to uncovered sections, more time may be required. Your house painters will provide you with a timetable outlining the project’s duration and will plan the task to prevent bad weather.
