The dry-in phase is a construction milestone where a building is sealed off from external weather elements. This stage is achieved once the roof, windows, exterior doors, and sheathing are installed, making the interior protected from rain, wind, and moisture.
It signals that the structure is weather-tight and ready for interior work to begin without risk of water damage.
The dry-in phase is used during residential and commercial construction projects to mark a transition from exterior to interior work. Reaching this point allows for scheduling trades like electricians, plumbers, and HVAC professionals without concern for weather-related delays or damage.
It’s a critical milestone for lenders, inspectors, and insurance providers, often triggering inspections, draw payments, or updated coverage needs.
While not calculated with a strict formula, a dry-in is considered complete when all critical components that keep water out are installed and properly sealed. Builders often follow a checklist to confirm dry-in status, including roofing materials, windows, doors, flashing, and moisture barriers.
Once confirmed, the project can safely move forward with insulation, drywall, and other internal installations.
