Supervision is a technology platform providing automated cost benchmarks based on regional historical trade data and public building codes. Supervision is not a licensed general contractor, architect, structural engineer, or home inspector. Estimates are statistical approximations and exclude concealed, latent, or inaccessible defects (such as underground plumbing, hidden dry rot, ungrounded branch wiring, or hazardous materials). All scopes, prices, and specifications must be independently verified on-site by a licensed, insured trade contractor prior to signing contracts or waiving escrow contingencies.
How the Fair-Price Benchmark Audit Works
We eliminate the asymmetric knowledge gap between licensed tradesmen and homeowners.
Wholesale Parts De-bundling
Contractors frequently charge $2,500 for a water heater or condenser that sells for $850 at Ferguson or Johnstone Supply. We identify the exact SKU and isolate the true hardware cost.
Trade Labor Rate Benchmarking
We calculate the legitimate standard billable hours for your repair and apply prevailing union/independent wage rates for your zip code, stripping out padded "travel fees" and "buffer hours."
1-Click Standardized RFP
Turn the fair-market benchmark into a 3-language Scope of Work (EN / ES / ZH) and live contractor bidding link so local tradespeople compete transparently on your job.
