Attic

What’s hotter than the outdoors on a sunny summer day? Your attic. Keep the heat out of your living space with sealant around:

  • Plumbing stacks and shafts
  • Attic perimeter
  • Top plates
  • Gas lines
  • HVAC penetrations
  • Electrical and cable lines
  • TV connections
  • Look for dirty insulation, which can indicate air infiltration

Living Space

It’s where you eat, sleep and hang out, so don’t neglect the most important place in your home. Enhance your living space comfort by sealing:

  • Under baseboards
  • Gas line penetrations
  • Window and door frames
  • Around perimeter of electrical outlets (not inside box)
  • Plumbing penetrations
  • Around the perimeter of covered wire and electrical conduit penetrations on exterior walls
  • Air/heating vents
  • Central vac system piping

The great outdoors should stay outdoors. Seal these areas to help prevent dust, allergens and pests from finding their way inside:

  • Electric, gas, cable and air conditioning penetrations
  • Vent hoods
  • Exterior garage walls
  • Outside water faucets
  • Dryer vent
  • Cooling line from air conditioning condenser (outside on a concrete pad) and heat pump penetration into house

Keep your basement warmer and drier by strategically applying sealant to these key areas:

  • Sill plate
  • Rim/band joist
  • Floor/wall junction
  • Headers

  • HVAC duct penetrations
