Start with what you know.
Use measured length, width, area, depth or roofline. When you use a proxy, the page names it.
01 A clearer first conversation
Renovation Range turns a few measurements into a quantity or reference cost range you can carry into a material order or contractor conversation.
02 The point of the project
Home improvement quotes get easier to compare when the work is described before the total is discussed. These tools help with the first pass: footprint, depth, material, prep, access and visible extras.
Renovation Range is not a contractor marketplace, a lead form or a promise of exact local pricing. The calculator works without an account or contact details. Its result is a planning aid with a version, date and stated limitations.
The project is organized around transparent public pages: the methodology explains the formulas, and the data sources page explains the manifest and its reference points.
03 Pick the next useful step
04 A responsible handoff
Use measured length, width, area, depth or roofline. When you use a proxy, the page names it.
Ask what the written quote includes for preparation, access, removal, permits, taxes, cleanup and materials.
Site conditions, code, availability and professional judgment belong in the final quote and verification.
Use the result as a shared starting point with a supplier or contractor, then replace assumptions with measurements and a written scope.
