OBSERVATIONS

 Top Floor

  • Majority of sheetrock still in place.
  • Excessive amounts of mold growth found along bottom 2-3 feet of sheetrock in living room.
  • Visible mold growth found on exposed quik-crete floor in living room.
  • Some evidence of mold growth found on base of walls in bedrooms.
  • Tub still in place in bathroom. – Wet insulation is still located behind tub/shower surround.
  • Visible water marks noted around ceiling HVAC vent in living room.
  • Little to no mold growth noted on exposed wall sheathing where sheetrock had been removed.
  • Vinyl flooring was still present in kitchen. Moisture was found to be under the vinyl flooring still and should be removed to allow for complete drying.
  • Source of moisture appears to be a frost-burst copper supply line to toilet.

     Recommendations

  • Recommend removal of bottom 4 ft of sheetrock and insulation from living room, front closet, bathroom and kitchen.
  • Recommend removal of bottom two feet of sheetrock and insulation from bedrooms.
  • Recommend removal of sheetrock around stained HVAC duct in living room ceiling to investigate the source of the moisture.
  • All floors should be wet-mopped, HEPA vacuumed and treated with an EPA registered mildicide.
  • All areas of framing that exhibit residual staining and /or show three dimensional mold growth should be wire-brushed and/or HEPA vacuumed prior to being treated with an EPA registered mildicide.
  • All solid surfaces should be treated with an EPA registered mildicide and wiped down prior to rebuild.
  • Recommend negative pressure, HEPA air filtration once building envelope is sealed up.

 Middle Floor

  • Majority of framing had been removed prior to inspection.
  • South facing, exterior wall was having exterior sheathing removed due to excessive water and fungal damage.
  • Gypsum board fire blocking around HVAC ducting and ventilation ducting is saturated with moisture and shows heavy mold contamination.
  • Ventilation fan in bathroom has severe water damage and needs replacing.
  • Numerous locations were present where sheetrock was trapped between studs. This must be removed to allow for adequate drying of framing substrates.
  • Numerous locations were present on North and East facing walls where sheathing also exhibited excessive water and fungal damage.
  • Main exterior beam on NE corner of home was not sealed to siding correctly and has allowed moisture intrusion to occur and damage the exterior siding and sheathing.
  • Water damage appears to have damaged exterior trim around many of the windows.
  • Heavy mold growth noted on sections of painted sheer wall near front entrance and SW corner of building.
  • Insulation is still present under the stairs and behind the tub/shower surround. This insulation is wet and needs to be removed to allow for adequate drying.
  • Heavy mold growth was noted on much of the interior framing and upper subfloor.
  • Elevated moisture levels were noted in most framing, sheathing upper subfloor.
  • Excessive water and mold damage noted on rim joists along north and south sides of the home.
  • Insulation was visible in many areas near rim joists.
  • Vinyl flooring was still present in kitchen area. Elevated moisture levels were noted under vinyl flooring and should be removed to allow for adequate drying to occur.

     Recommendations

  • Recommend removal of all remaining sheetrock, insulation and nails from framing, wall cavities and ceiling cavities.
  • All floors should be wet-mopped, HEPA vacuumed and treated with an EPA registered mildicide.
  • All areas of framing that exhibit residual staining and /or show three dimensional mold growth should be wire-brushed and/or HEPA vacuumed prior to being treated with an EPA registered mildicide.
  • Gypsum board must be removed from around all HVAC and bathroom venting.
  • Once building envelope is sealed, it is highly recommended that drying equipment be installed as soon as possible. Moisture content levels of most substrates are above 20% moisture by content which will allow for mold growth to continue, even after remediation.
  • Ventilation fan(s) should be removed and replaced due to excessive water damage and corrosion.
  • Recommend wire brushing and/or HEPA vacuuming all remaining sheathing, framing and ceiling joists and subfloor to remove any three dimensional mold growth from these surfaces.
  • Recommend exposing exterior beam and sheathing on NW corner of building to allow for proper remediation, repair and sealing up of surfaces.
  • Recommend removing vinyl flooring from kitchen to allow the quick-crete to dry underneath.
  • All solid surfaces should be treated with an EPA registered mildicide and wiped down prior to rebuild.
  • Recommend negative pressure, HEPA air filtration once building envelope is sealed up.

 Lower Floor

  • Majority of framing had been removed prior to inspection.
  • South facing, exterior wall was being disassembled to remove sheathing due to excessive water and fungal damage.
  • Gypsum board fire blocking around HVAC ducting and ventilation ducting is saturated with moisture and shows heavy mold contamination.
  • Ventilation fan in bathroom has severe water damage and needs replacing.
  • Numerous locations were present where sheetrock was trapped between studs. This must be removed to allow for adequate drying of framing substrates.
  • Numerous locations were present on North and East facing walls where sheathing also exhibited excessive water and fungal damage.
  • Heavy rot was noted on North facing sheathing in several locations.
  • Water damage appears to have damaged exterior trim around many of the windows.
  • Insulation is still present behind the tub/shower surround. This insulation is wet and needs to be removed to allow for adequate drying.
  • Heavy mold growth was noted on much of the interior framing and upper subfloor.
  • Elevated moisture levels were noted in most framing, sheathing upper subfloor. Moisture contents of building materials on lower floor were significantly higher than floor above.
  • Excessive water and mold damage noted on rim joists along north and south sides of the home.

     Recommendations

  • Any persons working in this unit should be wearing a minimum of a N-95 respirator to minimize exposure to airborne mold growth.
  • Recommend removal of all remaining sheetrock, insulation and nails from framing, wall cavities and ceiling cavities.
  • All areas of framing, sheathing, ceiling joists and subfloor should be wire-brushed and/or HEPA vacuumed prior to being treated with an EPA registered mildicide.
  • Gypsum board must be removed from around all HVAC and bathroom venting.
  • Once building envelope is sealed, it is highly recommended that drying equipment be installed as soon as possible. Moisture content levels of most substrates are significantly above 20% moisture by content which will allow for mold growth to continue, even after remediation.
  • Ventilation fan(s) should be removed and replaced due to excessive water damage and corrosion.
  • All solid surfaces should be treated with an EPA registered mildicide and wiped down prior to rebuild.
  • Recommend negative pressure, HEPA air filtration once building envelope is sealed up.
