What Contractors Don't Tell You

The average homeowner overpays 12–25% on construction — here's where the money goes

💸

Inflated Unit Prices

Material costs marked up 20–40% above supplier rates. Labor billed at premium rates for standard work. Without an independent cost check, you're trusting a number no one verified.

📋

Missing Scope of Work

The bid looks complete — until mid-build. Drainage, vapor barriers, fire-rated assemblies, structural connections. Each missing item becomes a change order at 2–3x the original price.

⚖️

Building Code Violations

Plans that don't meet IRC, IBC, or local municipal codes get rejected at plan review. That means redesign fees, resubmission delays, and contractors who charge you for the rework.

Documents We Audit

Upload any construction document — our platform knows what to look for

📊

Cost Estimates & Contractor Bids

Line-by-line price verification against current material and labor rates. We flag inflated quantities, duplicate items, and unreasonable markups.

📐

Blueprints & Architectural Plans

Structural integrity, load paths, egress requirements, room dimensions, and compliance with IRC/IBC residential standards.

📄

Construction Contracts

Unfavorable payment terms, missing warranty clauses, vague scope definitions, hidden fees, and liability gaps that put you at risk.

🔧

Change Orders & Pay Applications

Verification of AIA G702/G703 forms, change order pricing, progress billing accuracy, and scope creep identification.

🏛️

Permit Documents & Specifications

Building permit readiness check against local codes, zoning requirements, setback rules, and energy code (IECC) compliance.

MEP & Engineering Drawings

Mechanical, electrical, plumbing plans reviewed for NEC compliance, load calculations, pipe sizing, and HVAC system adequacy.
