Air sealing your home is one of the most effective ways to improve home energy savings and your home’s comfort. Air leaks from small holes, cracks and gaps allow valuable conditioned air to escape. Warm air in your house will naturally rise and leak out any holes in your attic. This rising movement causes cooler air to be drawn up in through cracks in your crawlspace or basement. Sealing the air leaks in your home will significantly reduce your energy costs with an almost immediate return on your investment.
Benefits of Air Sealing
Sealing gaps and holes in your home’s envelope can eliminate annoying drafts. Your heating and cooling systems will maintain temperature and distribute conditioned air more evenly. Many of our customers enjoy increased comfort, along with reduced energy costs, that start on the first day of house sealing.
Air Sealing & Insulation
Home attic sealing is often the first step Energeyes recommends when replacing old or ineffective insulation. Your sealed attic will prevent air from leaking between attic spaces and your living areas, and ensure your insulation is effective in keeping your home comfortable.
How is Air Sealing Done?
First, your Energeyes air sealing expert will locate the air leaks in your home. While we can locate some leaks visually, employing a blower door test and using infrared imaging can spot smaller, less visible cracks. Once the holes and cracks in the home have been located, our technician will begin the detailed process of sealing. We will apply different products depending on the size and nature of the gap, including caulking, spray foam or heat-resistant products to avoid a fire hazard.
Can a Home Be Too Airtight?
Because humans need an abundant supply of oxygen to breathe, a healthy home needs to have a supply of fresh air. Before energy efficiency became important, many homeowners felt their homes needed to “breathe.” However, these gaps and cracks combine to allow much more outside air than is needed — often the equivalent of leaving a window or two open all year long! The key to air sealing and maintaining proper airflow is controlled ventilation. Once your home is air sealed it’s important to address:
Excess Moisture Control
Daily activities of cooking, showering, and clothes washing create excess moisture inside of your home. Proper ventilation must be in place to help remove that moisture so that it does not cause mold and discomfort from high humidity.
Combustion Gases Ventilation
Gas-burning burning appliances in your home must be properly ventilated to avoid the dangerous buildup of carbon monoxide (CO) in the home. Each gas-fired appliance should be safety tested to ensure it has a ready supply of oxygen to burn and ventilation for the gases that result.
