Air Sealing

Many Waimea, Waikoloa, Kailua-Kona and Hilo homeowners looking to make their homes more comfortable think that they need one of these two things:

  • air conditioning
  • insulation

But…there’s a third thing nobody talks about.


The third thing is “air sealing.”  It’s so important that it’s written into building codes.

Think about it.

If you have AC…does it work if that cold air leaks out of your home quickly?

If you have a dehumidifier…does it work if the dry air leaks out quickly?

If you’re hot in a house with big, hidden holes in it…will messing with the thermostat help you?

If you’re a landlord with vacation tenants who run up your electric bill…is it really their fault?

“Insulation” is important, but it’s not the only piece of the puzzle. Even the best high-performance insulation can’t do its job sometimes if the building envelope isn’t sealed.


Air sealing is the process of finding and filling cracks and gaps with specialized materials to ensure that your home’s building envelope is as sealed as reasonably possible. Typically this is best done during construction, after the electricians and plumbers have come through and made all their holes.


When your home isn’t sealed, and air flows freely in and out, conditioning it can be a challenge. Older homes are especially subject to the issue, as wear and tear over the years can increase the size of the holes and make the problem worse. Air sealing your home can bring the following benefits:

  • Enhanced Home Performance
  • Boosted Home Comfort
  • Reduced Energy Bills
  • Better Indoor Air Quality
  • Fewer Drafts!
