These wait times can vary throughout the year with late Spring  & Summer having the longest lead times.  Typically when you call to book an appointment, they can be made within one to two weeks.   Installation will vary based on project type and season.  Peak season (summer) can be as long as 4-6 weeks, but can be as short as one week.  The salesman assigned to your project will be able to give you a close estimate on installation times at the point of your appointment.  All installation times are approximate as weather conditions and other factors can present small delays at times.
