Evaluation of gymnasium floors
Light Frame Structures
Wood Advisory Services is frequently called upon to assess performance problems in light frame wood structures. Many performance deficiencies in these structures are due to poor construction practices, design errors, moisture problems, or defective materials. In addition to common residential and commercial light structures, we have been called upon to evaluate performance problems in very specialized applications, such as pool buildings, log homes, bowling alleys, ice-skating rinks, and timber-frame structures. Our services have typically included:
  • General assessment of light frame construction
  • Analysis of paint failures
  • Evaluation of moisture, decay, and insect problems
  • Assessment of wood siding performance
  • Dimensional instability and warpage analysis
