Quote Risk Check

A first pass before you sign, not another renovation calculator.

The Chinese tool checks whether a renovation quote clearly states scope, materials, quantities, change-order rules, acceptance standards, warranty scope, and payment milestones. It does not decide whether a contractor is “good.” It tells you what is still too fuzzy to sign comfortably.

Risk Language

Harmless-looking phrases that deserve a second look.

Billed by actual quantity

Reasonable when the scope is truly unknown, dangerous when the unit price, cap, and approval step are missing.

Same-grade substitute

A gentle phrase that needs hard details: brand, model, specification, and written approval rules.

Subject to site conditions

Sometimes fair, often too elastic. Ask what counts as a change, who confirms it, and whether there is an upper limit.

Payment milestone

Money should follow verified progress. If payment runs ahead of leverage, every later correction gets harder.

Checklists

Questions you can actually ask, not downloadable clutter.

Each checklist is designed to move important promises out of chat and into the quote, contract, or written addendum.

Project Risk Library

Every line item has a boundary.

The project library answers long-tail quote questions such as “What should waterproofing include?” or “How should plumbing and electrical work be priced?” It always comes back to quote clarity before signing, not construction tutorials.
