How gaps and cracks form in the attic

Air sealing before & after

air sealing before

Before: Recessed can lights such as the one shown here can't have insulation batts covering them by building code. However, leaving them completely exposed allows for significant air flow between the attic and the room below.

air sealing after

After: Sealing around the light with our expanding foam is a safe, effective way to eliminate this air flow. This will prevent conditioned air from escaping to the attic, keeping your home more comfortable and saving you money.

Understanding how air flow works in your home

Why does air sealing make such a big difference in your home? Simply put, a lack of air sealing allows too much air flow between the living space and the attic. Here's how it affects your home in different seasons:

  • Winter: Warm air rises, and the warm air you paid to heat will naturally rise to the ceiling. If there are gaps in the ceiling and attic floor, that warm air will leak into the attic, forcing your furnace to run longer to keep the home at the right temperature.
  • Summer: In the summer, hot and humid air from the outside moves into your attic. This is part of why your attic is so hot during the summer, but it also serves to heat up the rooms directly below the attic. Sealing gaps and cracks to the outside will prevent this air transfer.

How we solve air sealing problems in your home

The first step of air sealing is testing the attic to identify where the air leaks are. Once we know, we use an expanding foam to seal the areas and prevent air transfer. The result will be a much more efficient and comfortable home because your HVAC system won't need to run as long to get the house to the temperature you want.

The following are common areas where air sealing is required in the attic:

  • Plumbing and wiring penetrations through the attic floor
  • HVAC ductwork, chases, vents, and registers
  • Chimney chases
  • Attic access hatches, doors, and drop-down stairs
  • Recessed lights and fans in ceilings
