Common Questions from Window Installers
Can I price each window individually?
Yes. Add each window as a line item with its size, style, unit cost, and installation labor. Clients see exactly what each window costs.
How do I show different window quality tiers?
Create separate services for each tier — builder grade, mid-range, premium — each with its own window pricing and features description.
Can I include trim work in my window estimates?
Yes. Add trim, capping, caulking, and insulation as separate line items under each window or as a separate service section.
