Air Sealing in St. Louis

Air Sealing in St. Louis. You depend on your St. Louis area home to protect you from the unpredictable elements of the outdoors — but did you know that tiny cracks and gaps in the construction of your home can also pose a threat to your overall comfort, and more importantly, your health? 

By air sealing your St. Louis house, you can live in a home that keeps harmful pollutants and contaminants outside, keeps your indoor temperatures stable, and reduces your indoor drafts. We often recommend combining air sealing in St. Louis with an insulation upgrade, to boost the effectiveness of both home improvements. Here is what you should know about air sealing in St. Louis, and why trusting SmartHouse with your air sealing project is the smart call.

Where Can Air Leaks Come From? | Air Sealing in St. Louis

You may not be able to see most of these cracks and gaps, but the most likely culprits include:

  • Plumbing
  • Flue chases
  • Attic hatches
  • Recessed lighting
  • Other structural components

These ‘big’ leaks are hard for most St. Louis homeowners to diagnose and fix, and can be up to 20 times more wasteful than all of the minor and obvious leaks throughout a house. As Building Performance Institute certified building science professionals in St. Louis, the team at SmartHouse believes (and the US Department of Energy agrees) that the combination of insulation and air sealing provides optimal improvement and should be incorporated in nearly every home.

The Benefits of Air Sealing in St. Louis

A St. Louis home free of air leaks will provide many benefits you may not have considered. Take your indoor air quality for example: the fewer areas where outside pollution can infiltrate your home, the less work your St. Louis ventilation systems will have to do to prevent those contaminants from recirculating in your breathing air. 

Air sealing your St. Louis home offers:

  • Reliable indoor temperatures
  • Fewer indoor drafts
  • Increased indoor air quality
  • An increase in energy efficiency 
  • Reduced heating & cooling costs

How SmartHouse Performs Air Sealing For Your St. Louis Home

Before we even begin closing up any holes, we’ll test your entire St. Louis home to determine where the leaks are coming from. This is done using a blower door test to give us the total amount of leakage present, and then we identify the exact location of the leaks using infrared imaging (as well as our decades of building science experience).

Once we’ve identified the sources of your woes, we seal up the leaks using an expanding spray foam insulation material. This fills the leak entirely, and prevents heat from escaping or infiltrating your St. Louis home through the newly installed material. 

A few tips for air sealing in St. Louis:

  • Air sealing in St. Louis cannot be performed without blower door testing or combustion safety testing. These steps are necessary to assure that the house always maintains enough air exchange for its occupants. If a contractor says they can seal your house without testing, you should run the other way.
  • Insulation needs to be installed properly to be effective. Even small gaps can result in dramatically reduced effectiveness. If you covered 98% of your attic correctly, but left 2% exposed, your insulation’s performance would be reduced to 58%.
  • More insulation is not always better. There is a point of diminishing return beyond which your investment may not be worthwhile.
