Attic air sealing before insulation checklist
A pre-insulation air-sealing checklist for defining the pressure boundary, exposing and sealing top plates, plumbing and wiring penetrations, chases, dropped soffits, partition transitions and attic hatches with compatible materials; treating large openings with rigid backing, preserving flue and electrical clearances, coordinating kneewalls and ducts, avoiding moisture trapping, documenting concealed work and verifying completeness before loose fill, batts or spray foam make bypasses difficult to find.
Attic ventilation baffles before insulation checklist
A pre-cover attic ventilation checklist for confirming the approved vented or unvented roof strategy, documenting soffit and other intake openings, installing durable baffles that maintain the designed air path, protecting insulation from wind washing, keeping roof vents, fans and mechanical exhaust distinct, preserving clearances at roof decks and eaves, sealing the ceiling boundary below, coordinating narrow bays and obstructions and photographing each eave before insulation hides the intake and baffle work.
Attic insulation depth and coverage final acceptance checklist
A final attic insulation checklist for confirming the specified material and thermal target, verifying installed quantity and bag or coverage documentation, measuring representative depth without compressing material, checking complete coverage at eaves, corners, platforms, kneewalls and around obstructions, preserving baffles, flue and fixture clearances, inspecting dams and access, identifying voids, wind washing, wet or contaminated material, protecting ducts and controls and documenting labels, photographs, rebates and correction before final payment.
Blower-door and combustion-safety verification after air sealing checklist
A post-work verification checklist for confirming the building is ready for diagnostic testing, recording blower-door setup and baseline comparison, locating remaining major leakage without damaging assemblies, evaluating pressure relationships and exhaust interactions, completing qualified combustion-safety checks for affected fuel-burning equipment, confirming ventilation and makeup-air provisions, correcting unsafe or out-of-scope results, retesting after corrections and delivering an understandable report rather than treating a single leakage number as proof of comfort, moisture control or indoor-air quality.
