Maison Témoin The Science of Systematic Acceptance
The Invisible Liability. The costliest defects are rarely dramatic — they are quiet deviations that pass unnoticed during the build, then surface after handoff as cascading warranty liabilities. Maison Témoin provides the internal authority layer developers use to bridge the gap between “finished” and “engineered.”
Our Proprietary Framework
Structured field observation that cross-references critical assets against their Golden Standard. Through the Indice Jour Un™ lens, performance is verified before keys are in hand — aligned with manufacturer tolerances.
Golden Standard Verification
We reference manufacturer documentation as the controlling baseline and flag materially significant deviations early — while correction remains routine inside the developer’s process.
Registre Maison™ — A Nationwide Standard
Every observation is logged in a serialized ledger, creating a persistent “medical history” of system behavior. Developers can detect systemic subcontractor patterns across portfolios — shifting from reactive service to proactive risk control.
Maison Témoin observes and documents only. Corrective work remains the domain of licensed trades and the developer’s process.
The Maison Témoin Framework: Residential Risk Intelligence
Indice Jour Un™ | The Baseline Index
An uncompromising technical baseline established at the point of first engagement. Indice Jour Un™ serves as the definitive reference point — monitoring for deviations from engineered performance standards rather than simple code compliance or binary pass/fail ratings.
Registre Maison™ | The Serialized Ledger
A persistent digital continuity file capturing the “medical history” of the asset. Every observation, thermal scan, and technical triage is serialized — providing developers with a defensive data trail and homeowners with a record of stewardship that transfers with the property.
Audit Maison Garde™ | Structured Protocol
Our exhaustive observational protocol. We analyze system behavior, moisture dynamics, and envelope integrity. Each data point is cross-referenced against Manufacturer Golden Standards to identify quiet deviations before they become dramatic failures.
Couche Prévention™ | The Prevention Layer
A dedicated loss-prevention layer focused on high-risk mechanical junctions. From condensate path verification to appliance coil health and dryer-vent backpressure, findings are documented and routed for licensed trade verification prior to closeout.
Bouclier Grille™ | Grid Shield
Advanced electrical and grid-stress diagnostics. Utilizing thermal panel scanning and load analysis, we assess readiness for high-demand loads including EV infrastructure and battery storage — ensuring the electrical “heart” of the home is resilient.
Structured Triage | Predictive Routing
Risk is not a monolith. Every observation is filtered through structured triage and categorized from Routine Maintenance to Systemic Risk. This routing allows developers to manage warranty exposure with scientific precision.
Engagement Sequence
Pre-Drywall Baseline
Indice Jour Un™ is established post–rough-in / pre–drywall and serialized into the Registre Maison™.
Structured Observation
Material field observations are documented with photo proof and categorized under triage discipline.
Golden Standard Reference
Findings are cross-referenced against Manufacturer Golden Standards while correction remains routine.
Continuity (Optional)
Post-close continuity may be extended by request to preserve longitudinal system history.
- Primary: Post–rough-in / Pre–drywall baseline issuance
- Secondary: Structured triage routing for developer coordination
- Optional: Continuity cadence if extended post-close
The Maison Témoin Developer Integration
The Highest Leverage Point
Maison Témoin is retained during construction at the point of maximum influence: post–rough-in and prior to drywall. This is the window where materially significant deviations can be captured while correction remains routine — not structural renovation.
Deliverables include baseline issuance and structured routing memos designed for developer coordination, warranty defensibility, and long-horizon asset performance.
Developer Value
- Reduced downstream warranty escalation and fragmented homeowner outreach
- Earlier detection of systemic subcontractor pattern risk across portfolios
- Lower closing concessions tied to post-handoff mechanical surprises
- Serialized continuity record supporting defensible service history
- Future-proofing readiness for high-demand electrical infrastructure

Maison Témoin: Strategic Boundaries
The Independent Observational Authority
Maison Témoin functions strictly as an observational documentation layer. Indice Jour Un™ is a descriptive baseline reference only — not a rating, grade, certification, code-compliance approval, engineering signoff, or warranty determination.
No Repairs Performed
Maison Témoin does not execute corrective work. We provide structured documentation for the Registre Maison™; all corrective actions remain the exclusive domain of licensed trades and the developer’s existing process.
Not Warranty Administration
Warranty-potential findings are routed directly into the developer’s established workflow. Developer obligations and consumer warranty terms remain unchanged.
Single Coordination Channel
All requests and next steps flow through Maison Témoin to preserve project integrity. Field observers do not quote, diagnose, or schedule work independently.
