Weatherstripping Installation Verification

Inspection template for door assembly QC to verify weatherstrip type, seating, continuity, and seal integrity on assembled doors.

Inspection Identification

• Door and job identification recorded
  Record the door number, job/order number, location, and inspection date.
• Weatherstrip specification or BOM reference available
  Document the approved weatherstrip type, profile, finish, and reference document used for verification.
• Inspector identified
  Enter the name or ID of the inspector completing the verification.
• Inspection stage confirmed as assembled door QC
  Confirm the door is fully assembled and ready for final QC verification.

Weatherstrip Type and Installation

• Installed weatherstrip matches approved specification
  Verify the installed weatherstrip type, profile, and material match the approved specification and have not been substituted or modified.
• Weatherstrip is fully seated in the intended retainer or kerf
  Check that the weatherstrip is properly inserted, seated, and retained without lifting, twisting, or partial engagement.
• No visible cuts, tears, deformation, or damage
  Inspect the installed weatherstrip for physical damage, compression set, splits, or other defects that could affect sealing performance.

Continuity and Seal Coverage

• Weatherstrip continuity is complete around required perimeter
  Verify continuous coverage at all required contact edges with no missing sections, breaks, or open joints.
• Corners, joints, and end conditions are properly joined
  Check that corners and splice points are cleanly joined and do not create gaps, overlaps, or discontinuities in the seal line.
• Compression and contact appear uniform along the seal line
  Rate the uniformity of weatherstrip contact against the mating surface across the full perimeter.

Door Fit and Functional Check

• Door closes and latches without binding on weatherstrip
  Confirm the door closes fully and latches properly without excessive force, drag, or interference from the weatherstrip.
• Visible gap or light leakage at perimeter is within acceptable limit
  Measure any visible perimeter gap where applicable and record the result.
• Weatherstrip does not interfere with hinges, hardware, or thresholds
  Verify the seal does not obstruct hinges, latches, closers, astragals, thresholds, or other installed hardware.

Compliance, Deficiencies, and Sign-Off

• Fire-rated assembly requirements considered where applicable
  If the door is fire-rated, confirm the weatherstripping installation does not modify the listed assembly and remains consistent with the approved fire door components and AHJ requirements. Reference NFPA 80 where applicable.
• Deficiencies documented with corrective action
  List any non-conformances, including missing sections, misalignment, damaged material, or rework required.
• Inspector signature
  Inspector signs to confirm the verification was completed accurately.
