This is a project we went to work on with dryer ventilation issues. By remedying these issues we were able to stop the progress of mold and prevent mold regrowth in their home.

Improper Dryer Ducting & No Vent Found Outside


  • Home Built in last 2 yrs.
  • Inspection was of garage only.



  • Dryer vent was found to not exit the ceiling cavity of garage.
  • Elevated moisture levels were found on rim joist and some subflooring.
  • Visible mold growth was present on rim joist only.
  • Sheetrock is two layers for fire code.
  • Insulation was present in ceiling cavity and was found to be wet to the touch. Insulation was removed at the time of inspection.
  • Visual inspection inside ceiling cavity did not reveal any other major damages.
  • Steel gas line inside ceiling cavity was rusty and appeared good condition, however it is recommended that it be checked by a qualified technician.
  • An inspection hole was cut into the lower section of sheetrock wall directly under the dryer vent. No visible mold or elevated moisture levels were noted inside wall cavity.


Wet Wood & Insulation inside Ceiling Cavity

  • Recommend removing all sheetrock along first ceiling joist bay.
  • Garage door hangers may remain in place.
  • Remove all insulation from open ceiling cavity.
  • Recommend drying out underlying substrate prior to re-insulating and repair.
  • Dryer vent must have an exit hole cut into exterior of home and an appropriate vent hood installed and sealed.
