Carpet Inspection Guide: Diagnosing Lack of Proper Power Stretching

For FCITS-Certified Independent Inspectors

Improper power stretching during carpet installation is a common cause of performance issues such as rippling, buckling, and premature wear. As an FCITS-certified inspector, your role is to determine whether the carpet was installed according to industry standards—particularly those outlined by the CRI 105 Residential Installation Standard or CRI 104 for Commercial.

Inspection Objectives

• Identify signs of inadequate stretching.
• Determine if installation meets industry standards.
• Document findings clearly for manufacturers, installers, or homeowners.

Step-by-Step Inspection Protocol

1. Pre-Inspection Preparation
   • Review Carpet Type & Installation Method: Confirm if the carpet is stretch-in, glue-down, or double glue-down
   • Gather History:
     • Installation date
     • Installer credentials
     • Subfloor type and condition
     • Environmental conditions (humidity, temperature)
2. Visual Examination
   • Look for:
     • Ripples or buckling, especially in traffic lanes or near transitions.
     • Loose edges or corners.
     • Seam separation or misalignment.
     • Check for furniture placement that may have restricted proper stretching.
3. Tactile & Physical Testing
   • Gently lift a corner or edge (if accessible) to assess tension.
   • Walk across rippled areas to feel movement or looseness.
   • Use a carpet tension gauge if available to measure stretch force.
4. Installation Standards Review
   • Confirm adherence to CRI 105/104 standards, which require:
     • Use of a power stretcher (not just a knee kicker).
     • Proper tack strip placement and anchoring.
     • Adequate stretch to eliminate slack and prevent future movement
5. Subfloor & Environment Assessment
   • Check for:
     • Subfloor irregularities that may contribute to buckling.
     • Moisture issues using a moisture meter.
     • HVAC operation and indoor climate control.
6. Documentation
   • Take clear photos of affected areas, transitions, and seams.
   • Record:
     • Carpet type and backing
       • Installation method
       • Environmental readings
       • Any deviations from CRI standards
