Common Questions from Siding Contractors
Can I estimate different siding materials?
Yes. Show vinyl, Hardie board, and wood options as separate services in one estimate. Clients compare costs and choose their preferred material.
How do I account for waste factor?
Add your waste percentage to your material quantity. If a house needs 20 squares, enter 22 (10% waste) to ensure full coverage.
Can I include soffit and fascia in my siding estimates?
Yes. Add soffit, fascia, and trim work as a separate service section with its own material and labor line items.
