Sequence Inspections to Protect Finished Work
Attic projects stack critical layers—air barrier, insulation, vapor control, and finishes—into a tight envelope. To avoid rework, map a milestone inspection plan that follows the assembly order: (1) framing/structural after any dormers, headers, or sistering; (2) rough MEP once electrical, plumbing, and HVAC lines are in and pressure-tested; (3) air barrier & insulation verification before drywall closes cavities; and (4) final after trim, fixtures, and commissioning. Each gate ensures the next trade builds on verified work, not assumptions.
Air Barrier & Moisture Control Verification
Before insulation, walk the shell and confirm continuity at knee walls, skylight shafts, top plates, and around boxes—use compatible tapes and mastic, not just foam. Photograph membranes, taped seams, and pan flashings for the record set. Where showers or wet bars exist, demand bonded waterproofing membranes, sloped pans, and a 24-hour flood test prior to tile. Duct all exhausts to the exterior with smooth, insulated pipe and backdraft dampers—never to soffits or the attic cavity.
Hold Points that Save Drywall
Block the schedule: no drywall delivery until insulation inspection passes; no painting until HVAC startup and dehumidification are online; no tile until wet-area membranes are signed off. Book special inspections (structural connections, air-sealing/energy) as soon as the workplan locks so a missing signature doesn’t force tear-outs later.
Closeout & Commissioning
Finish strong with a blower-door test and duct leakage check; verify bath fan flow and ERV balance if installed. Assemble a homeowner packet (cut sheets, glazing ratings, paint formulas, warranties) and label access panels for shutoffs and filters. This documentation speeds future service without opening finished assemblies.
