Most Northern VA, Maryland and DC homeowners are looking to increase their home energy efficiency and decrease their energy costs, and two areas where houses see the most benefit are upgraded insulation and air sealing. While this work can be completed separately, homeowners will see the biggest changes when insulation work and air sealing are done together.

What You Should Know About Insulation & Air Sealing:
  • Insulation Works Year-Round

    Most people think of insulation only as a benefit during the winter months, when it helps keep their homes warm and protects against cold outdoor weather. But insulation is just as effective in holding the summer heat at bay, and can keep your home comfortable in the hottest months of the year as well.

  • Types of Insulation

    There are a number of different insulation options to consider for your home, including spray foam insulation, blown-in/loose fill cellulose, and fiberglass batts. All of these can help make your home more comfortable, reduce energy costs, and keep conditioned air inside where it belongs.

  • Understanding Air Leaks

    Your home’s attic is a prime candidate for energy loss, and while there might be existing insulation in your attic floor, small air leaks and cracks can significantly affect its energy efficiency. Air sealing, together with insulation, keeps conditioned air inside your living areas.


  • An Air Sealing Analogy

    If you step outside on a cold windy day with nothing on but a loose-knit sweater, the sweater will immediately let the cool air in through the holes and you’ll be cold. But throw a windbreaker on over the sweater and you’ll both stop the cold air and stay insulated against the freezing temps. This is the same way that air sealing and insulation work together to increase your home comfort.

  • Where to Find Air Leaks

    Even the tiniest gaps and cracks can let a substantial amount of conditioned air escape your home. The most common places air gets in and out of your living space include around recessed lighting, duct chases, and outlets and switches.

  • The Benefits of Insulation & Air Sealing

    Time and again at Home Energy Medics, we've seen the benefits of insulating and air sealing a home, including reduced energy consumption, increased comfort levels, improved indoor air quality and home safety, and an overall boost in home efficiency.

Looking for Duct Sealing? Did you know...

There is a substantial amount of energy loss when your HVAC system works overtime to make up for leaks and gaps in your ductwork. In addition to increased energy bills, the unnecessary strain on your system can significantly shorten its lifespan or lead to costly repairs. Air duct leaks can also create indoor air quality issues by allowing dust, allergens, and other pollutants easy access to the air circulating through your home. Having properly sealed ducts keeps these pollutants out of the air you breathe and balances temperatures, leaving your home feeling more comfortable.
