Frequently asked questions
Are these national price estimates?
No. Use current local quotes; labor, materials, access, code and site conditions vary.
Can I use the site outside the United States?
Yes. U.S. terminology is the default, but metric units and common international currencies are supported.
Does the site provide DIY installation instructions?
No. It focuses on planning, procurement, scope comparison and lifecycle.
How should contractor bids be compared?
Put every bid on the same scope: quantities, system, preparation, access, permits, schedule, warranty and exclusions.
Why are commercial quotes so different?
Contractors may be pricing different product grades, site assumptions, working hours, preparation and exclusions.
