The cheapest time to catch an envelope defect is before it's covered up. CSF provides independent, third-party quality observation during construction — checking that flashing, waterproofing and cladding details are actually being installed the way they were designed, before drywall or siding makes that impossible to verify.
What's included
- Scheduled site observation at key envelope milestones
- Photo-documented verification against approved details and manufacturer requirements
- Direct, timely reporting of deficiencies while they're still correctable
When you need this
New construction and major re-clad or re-roof projects where the owner wants verification independent of the general contractor and the design team.
