Frequently Asked Questions
What is a square of siding?
A square is 100 sq ft of siding coverage. It's the standard unit for quoting all lap siding materials.
How many squares of siding for a 2000 sq ft house?
Rough estimate: exterior wall area of a 2000 sq ft house is about 1600-2000 sq ft = 16-20 squares. This varies by wall height and window count.
How much waste should I add for vinyl siding?
Add 10-15% for waste. Gable ends, corners, and complex roof lines increase waste. Simple rectangular walls need only 5-10%.
Do I need starter strip for vinyl siding?
Yes, starter strip is required at the bottom of each wall. It locks the first course of siding in place and provides the angle for proper water drainage.
What trim pieces are needed for vinyl siding?
Outside corners, inside corners, J-channel around windows/doors, undersill trim, and drip edge at the top of walls are the standard trim pieces.
