Common Questions from Garage Door Installers
Can I show different door options to clients?
Yes. Add each door option as a separate service — basic steel, insulated, carriage house — each with its own price. Clients choose the option that fits their budget.
How do I estimate opener installations?
Add the opener unit, mounting hardware, and installation labor as separate line items. Include old opener disposal as an add-on.
Can I create repair estimate templates?
Yes. Save templates for common repairs like spring replacement, cable repair, or off-track doors with standard pricing pre-loaded.
