Air Sealing – Residential Services

Air Sealing for Residential Property Owners

The importance of air sealing the building envelope prior to insulating can not be understated. A building that is not properly sealed can lead to air leakage, moisture penetration causing mold and mildew, heating and cooling issues, many more issues depending on the circumstance.

Our team will always recommend air sealing a building envelope prior to providing insulation services. Reducing the amount of air that leaks in and out of your home is a cost-effective way to cut heating and cooling costs, improve durability, increase comfort, and create a healthier indoor environment.

Reduce Heating & Cooling Costs

The air leaking through openings in your home is often conditioned air that you are paying to heat or cool. Air sealing with the use of foam and sealant in combination with insulation will provide an air tight seal and thermal barrier that ensures your conditioned air is staying where you want it.

Improve Durability

Air sealing a home correctly will mean dealing with some common environmental hazards that can damage the structure of the home. Air and moisture are two of the most common hazards. A properly sealed attic and crawl space can alleviate any issues caused by air or moisture penetration such as wood rot and rust. This can make your home a lot more durable.

Improve Comfort

Have you experienced sitting in a living room or bedroom that seams to be colder than the rest of the house? If so, you know all too well how air sealing can affect your level of comfort in your own home. Improper air sealing can lead to varying levels of heat retention that may not be evenly distributed throughout your home or residential property.

Create a healthier indoor air environment

Indoor air quality can be significantly affected by several factors. The below are some of the factors that can affect your indoor air quality:

  • Tightness of how tight or open the building envelope of your home is currently and/or after improvements.
  • The type and number of exhaust vents, access openings, and heating & cooling systems in the building.
  • The external environmental conditions such as temperature, humidity, altitude, etc.
  • The internal environmental conditions such as temperature, humidity, hvac equipment, etc.

Common Types of Air leakages for Residential Homes

More than any other time of year, you notice your home’s air leaks in the winter. Most people call these air leaks “drafts.” You may feel these drafts around windows and doors and think these leaks are your major source of wasted energy. In most homes, however, the most significant air leaks are hidden in the attic and basement. These are the leaks that significantly raise your energy bill and make your house uncomfortable.

But locating leaks can be difficult because they are often hidden under your insulation. In cold weather, warm air rises in your house, just like it does in a chimney. This air, which you have paid to heat, is just wasted as it rises up into your attic and sucks cold air in all around your home — around windows, doors, and through holes into the basement.
