A pre-drywall inspection is a systematic review of all in-wall and in-ceiling work before drywall is installed — the last opportunity to verify framing completeness (blocking, backing, fire blocking), MEP rough-in (pipe and wire locations, pressure tests), insulation (R-value, full cavity fill, air sealing), and any other work that will be concealed. It is the most economically significant QA event on a residential construction project because problems found before drywall cost hours to correct; the same problems found after drywall cost days or weeks. A missing blocking location for a wall-mounted TV costs $80 to add before drywall; it costs $600–$1,200 after drywall is painted and the TV is mounted. RainFire Builders conducts a formal project manager pre-drywall inspection on every project, with a signed checklist and photographic documentation of all in-wall work before any drywall is ordered.
