Substructure and groundwork
Surveyors verify excavation depths, trench cleanliness, reinforcement placement, and damp-proof membrane continuity before concrete pours. Invoices for substructure works remain frozen until laser-level benchmarks meet technical specifications.
Structural envelope and timbers
We physically audit load-bearing masonry, flitch beams, steel connections, and roof rafters against structural engineer drawings. Thermal insulation continuity and airtightness junctions undergo thorough inspection prior to external cladding closure.
Services rough-in and finish
Pressure testing of plumbing conduits, electrical circuit certification, and subfloor moisture readings must be documented. Only after our comprehensive snagging audit passes statutory thresholds is the contractor final retention tranche released.
No verified site sign-off, no contractor funds released.
We maintain absolute fiscal separation between your project account and the builder, requiring signed technical certificates for every single currency release.
Trade Craft halted a £48,000 drawdown when our underpinning showed 14mm lateral deflection. The contractor rectified the concrete collar at their own expense before work resumed.
