Our Attic Insulation Process

All of our expert crews follow these essential steps to ensure proper attic insulation installation:

  • Attic Air Seal: Seal holes and penetrations formed by, but not limited to, plumbing, electrical fixtures, wall joints, and any other accessible voids with foam and caulk.
  • Cover openings (such as dropped ceilings, soffits and bulkheads) into the attic area with a rigid material and seal to the attic side of the ceiling.
  • Seal around chimney and framing with a high-temperature caulk or furnace cement.
  • At the tops of interior walls, use long-life caulk to seal the smaller gaps and holes and expanding foam or strips of rigid foam board insulation for the larger gaps.
  • Install metal flashing, or like material, to maintain fire-safety clearance requirements (usually 3 inches) for heat-producing equipment found in an attic, such as flues, chimneys and exhaust fans. We also include light housings/fixtures unless the fixtures are IC (insulation contact) rated; IC rated lights are airtight and can be covered with insulation.
  • Make sure insulation doesn’t block soffit vents to allow for proper attic ventilation.
  • Install baffles to allow for proper soffit ventilation
  • Check the attic ceiling for water stains or marks, which indicate roof leaks or lack of ventilation.
  • Insulate and air seal your attic access if it’s located in a conditioned part of the house.
  • Properly insulate and air seal any knee walls or vertical walls with attic space directly behind them, including any skylights.
  • Ventilate your current bath fan with proper pipe and termination kits out of the attic space.
