How we calculate pricing
FairBuild Index is a pricing reference, not a bid. Every range is built from structured inputs and shown with its parts — so you can see where a number comes from instead of trusting a single figure.
Scope first, not averages
Most cost confusion isn’t a pricing problem — it’s a scope problem. Two estimates for “a bathroom remodel” often assume different tile work, waterproofing, and fixtures. FairBuild starts by defining the project scope (cosmetic refresh, tub-to-shower conversion, shower-focused remodel, or full remodel), because scope drives cost more than square footage does.
The model
For each scope we start from a Mid-South anchor price, then apply multipliers for bathroom size, finish level, and job complexity, plus a fixed add-on for a tile shower where it applies. Low and high figures bracket the most-likely number using simple bands, so you can explore realistic scenarios rather than a false single-point “exact” cost.
What a price is made of
A remodel price is not “labor plus markup.” We break each estimate into the parts that actually make it up: direct labor (field production), materials and fixtures, overhead (insurance, tools, supervision, scheduling), and contractor margin. Showing these parts is the point — it’s what lets a homeowner or contractor judge whether a quote is reasonable.
Estimate confidence
Accuracy depends on how well scope is defined, not how confident a number sounds. An early estimate with no site visit is useful for orientation; a scope-defined estimate can be compared like-for-like; a site-verified estimate based on measurements and condition checks is the closest reflection of real cost before work begins. FairBuild is designed to move you up that ladder, not to replace the final step.
Independence
FairBuild Index is independent. We don’t sell leads, take contractor placement fees, or tie our numbers to any single company’s bids. The goal is a neutral reference both sides of a project can trust.
Limitations
Our ranges are planning-grade estimates, not quotes or guarantees. Final costs depend on site conditions, contractor selection, material choices, scope changes, and market movement. Always obtain written bids from licensed contractors for committed work.
