drywall installation
Figure 1 - Hanging drywall

Drywall (sheetrock), or more specifically gypsum board, is a major source of client complaints. In addition to having a high degree of visibility, an aesthetically good drywall installation (Figures 1 & 2) depends heavily on a number of trades, especially framers.

There is now a greater frequency of problems with drywall application due to:

  • wetter framing materials,
  • higher levels of insulation,
  • faster construction scheduling,
  • increase in construction during winter months,
  • more helpers and less journeymen on the drywall installation crews.
