Upload your estimates, let our AI do the heavy lifting, and make a confident decision.
Drop 2-4 contractor estimates (PDF or photo). No account, no signup. Our AI reads every document and extracts the details you need to compare.
Each contractor's license is verified against the California CSLB database in real time. We check bond status, workers comp, disciplinary actions, and years in business. Then we compute a Trust Score (0-100) for each one.
Line items normalized, scope gaps highlighted, red flags called out, and payment terms checked against California law. You'll know exactly who's offering the best value and who to avoid.
Not just the price. We verify the contractor behind it.
We check the California Contractors State License Board in real time. Is the license active? What classification? Any suspensions or revocations?
Is the contractor bonded? Do they carry workers compensation insurance? If they don't, you're liable if someone gets hurt on your property.
We pull any complaints, citations, or disciplinary actions from the CSLB. Past problems are the best predictor of future problems.
Our AI normalizes line items across estimates so you can see exactly what each contractor includes and what they're leaving out.
California law limits deposits to $1,000 or 10% (whichever is less). We flag any contractor asking for more, and recommend a safe payment schedule.
Unspecified materials ("TBD"), missing scope items, unusually low prices, no warranty, excessive deposits. We catch what you might miss.
Based on six verified data points from public records and our own database.
We analyzed 847 kitchen remodel estimates submitted to Opsite in Q1 2026 across Los Angeles, San Francisco, and San Diego counties. The median cost was $287/sqf, with a wide range from $145/sqf (budget stock cabinets, laminate counters) to $580/sqf (custom European cabinetry, stone surfaces, structural changes).
The most concerning finding: 41% of estimates requested deposits exceeding California's legal limit ($1,000 or 10%, whichever is less). Many homeowners would have unknowingly overpaid before work even started. Additionally, 23% of contractors had at least one CSLB complaint on file that was only discoverable through our real-time verification.
Data source: Opsite platform, January-March 2026. 847 estimates from 312 unique contractors across 3 California metro areas. Methodology: AI parsing of uploaded estimate PDFs with automated CSLB verification.
California limits deposits to $1,000 or 10% of the contract, whichever is less. If a contractor asks for 50% upfront, that's a violation of CSLB regulations.
"Cabinets TBD" or "equivalent paint" in an estimate means the contractor hasn't committed to a quality level. You could end up with the cheapest product available.
One estimate includes the garage door, the other doesn't mention it. Our AI cross-references all estimates to find what's missing from each one.
If a contractor isn't bonded or doesn't carry workers comp, you have no financial protection and could be liable for workplace injuries on your property.
Industry standard is 1-2 years minimum for workmanship. A 90-day warranty means the contractor doesn't stand behind their work.
If one estimate is 40%+ below the others, they're either cutting corners on materials, underestimating the scope, or planning to hit you with change orders later.
