About Us
CostFinder.ai provides location-specific cost ranges for home services, construction projects, and pest control across the United States. Every cost figure traces back to a verified official source — not an AI estimate.
AI explains — never invents.
Our AI system reads verified cost data from the database and generates plain-English explanations. The AI is architecturally constrained — it can only reference numbers that exist in our verified database. It cannot generate, estimate, or fabricate cost figures. When you read that "roof replacement typically costs $8,000–$14,000", that range came from our data pipeline — not from an AI making a guess.
Our Data Sources
Four Verified Sources. Zero Invented Numbers.
CostFinder.ai draws from four primary sources, each chosen for reliability, coverage, and verifiability.
Bureau of Labor Statistics (BLS)
Government SourceThe Occupational Employment and Wage Statistics (OEWS) program from the U.S. Department of Labor tracks labor costs by occupation across every major metro area in the United States. This gives us authoritative, government-published data on what skilled tradespeople — plumbers, electricians, HVAC technicians, carpenters — are paid by region. Labor cost is the largest variable in most home service quotes.
HomeAdvisor / Angi
Consumer ReportsConsumer-reported cost data from homeowners who have completed real projects. When a homeowner in Denver reports what they paid to replace their roof, that becomes part of a verified dataset of actual spending. HomeAdvisor and Angi aggregate millions of these reports, giving us ground-truth data on what real projects actually cost — not what contractors estimate before the work begins.
CMS Medicare
Federal DataThe Centers for Medicare & Medicaid Services Physician Fee Schedule provides government-published reimbursement rates for thousands of medical procedures across all U.S. states and territories. These rates reflect actual allowed amounts adjusted for geographic cost differentials (GPCI), making them the most reliable source for medical procedure cost benchmarks nationwide.
Homewyse
Industry StandardThe industry reference for home improvement cost estimation, used by contractors, architects, and estimators across North America. Homewyse publishes detailed unit cost data for materials, labor, and equipment broken down by region. It is the reference professionals use when estimating residential projects, making it the most rigorous cost source for construction-related queries.
How It Works
From Source to Your Screen
Every cost figure passes through a four-stage pipeline before you see it.
Collect
Raw cost data is ingested from BLS flat-file downloads, Angi cost guide scrapes, CMS fee schedule releases, and Homewyse regional data.
Verify
Each data point is cross-referenced against at least one other source. Data without full provenance (source + date + traceable link) is rejected.
Enrich
AI generates plain-English explanations of what the data means — why costs vary, what factors affect pricing, what questions to ask. Numbers come from data, not AI.
Display
Location-specific cost ranges are served to users with full source attribution, data density indicators, and freshness timestamps.

How We Verify Data
Every cost figure in our database includes three required fields: the source it came from, the date it was collected, and a traceable link to the original source document or page. Data without full provenance is not published.
When multiple sources cover the same service in the same location, we cross-reference them. If they agree within a reasonable range, we report the range with confidence. If sources diverge significantly, we show a wider range rather than forcing a single number that could mislead users about cost variability.
Location pages are only generated when we have at least two verified, cross-referenced data points for a service in a given area. This means some smaller markets may have fewer pages at launch — we publish less rather than publish unverified estimates.
Data is timestamped and refreshed on a scheduled basis. Cost data older than a defined threshold is flagged for refresh before it expires. We do not show stale data without disclosing its age.
