Effective Air Sealing

Improve your home's energy efficiency & comfort with air sealing by Dr. Energy Saver

air sealing

Air sealing ensures your insulation works as intended.

Is your home expensive to heat and cool? Are some rooms in your home uncomfortable? Air leaks may be causing high energy costs and unpleasant temperatures. Air leakage occurs throughout the home as the air you pay to condition slips through cracks, joints, and other openings. This process forces your HVAC system to work harder and makes your home too cold in the winter and too hot in the summer.

Dr. Energy Saver dealers identify the sources of these problems in your home and provide complete air sealing services. We can help you eliminate leaks and make your home more comfortable and efficient. If you're interested in air sealing for your home, call us today to get started!

How air leaks affect your home

Why are air leaks so common in homes throughout the country? The answer is simple — homes are built that way. Every joint where walls or floors meet, every screw and nail hole, and every plumbing, electrical, and HVAC installation creates gaps that allow air to exit or enter the home.

Hot air always moves to cooler spaces, meaning warm air in your home works its way outside in the winter, while hot air in the summer finds a way in. As a result, your HVAC system must work harder and longer while you deal with uncomfortable rooms.

There's almost nothing that the contractors who built and have worked on your home could have done to prevent these small gaps and leaks. However, you can eliminate these issues with air sealing from Dr. Energy Saver.

What is air sealing?

Air sealing is the process of closing any cracks, gaps, joints, and other openings around your home. Oftentimes, air sealing your attic, basement, and air ducts is the most effective because these areas are the most prone to air leakage. When you air seal your home, you will notice enhanced air quality, less humidity, and increased comfortability. Plus, your home will no longer require a large amount of energy to heat and cool.

Dr. Energy Saver dealers use industry-leading ZYP Foam, a low pressure single-component polyurethane foam sealant crafted to seal, fill, bond, and stop air infiltration in spaces where a fire block product is required. Another method we use is weatherstripping, which is used for moving components, including operable windows and doors. These two techniques are simple, but highly effective in preventing air leakage.

Common air sealing locations

Here are some of the locations where air leakage occurs in a typical house:

  • Plumbing & wiring penetrations through floors, walls, & ceilings
  • Chimney penetrations through insulated ceilings & exterior walls
  • Attic access hatches, doors, & drop-down stairs
  • Recessed lights & fans in insulated ceilings
  • Weatherstripping around windows & exterior doors
  • Cracks, gaps, & holes in drywall or plaster
  • Electrical outlets & switches, especially on exterior walls
  • Gaps around window & door trim & baseboard moldings
  • Dropped ceilings & soffits
  • Leaky basement windows
  • Rim joists in the basement or crawl space

Dr. Energy Saver air seals key areas in your home

When identifying air sealing problems in a house, there are usually three key areas where air leakage is the biggest problem:

  • Attics: More air leaks out of the home through the attic than anywhere else. Warm air naturally rises, and attics are typically under-insulated and full of gaps and cracks. This allows the air you pay to heat to escape the house.
  • Basements: When air leaks out of the house, it is usually replaced by air being sucked in on the lower levels of the home. By air sealing the basement, you can prevent unwanted cold or humid air (depending on the season) from entering the home.
  • Ducts: One of the most important source of air leaks is actually the ductwork system. Leaky ducts allow conditioned air before it reaches its destination while also pulling in unconditioned air from the attic or basement, depending on where your ducts are. This means your furnace or AC unit has to run longer to get the air to the temperature you want.

Air Sealing FAQs

Does air sealing a house work?

Yes, air sealing your home works to reduce heating and cooling costs, enhance home comfort, and increase your home's value. It works by preventing air leakage. Air leakage allows warm air to escape during the winter and move inside during the summer, leading to uncomfortable temperatures throughout the year.

What is the difference between air sealing and insulation?

While insulation controls heat flow in and out of the home to keep hot temperatures outside during the summer, air sealing minimizes the movement of air into and out of your home. These complement each other and ensure that your home remains comfortable and efficient no matter the season.

Should attics be sealed?

Air sealing your attic is a worthwhile investment to keep energy bills stable and to maintain a comfortable temperature year-round. Unsealed attics allow hot air inside during summer and allow heat loss during winter, resulting in uncomfortable temperatures throughout the year. Frequently, your attic is home to the largest gaps and openings, so it is crucial to focus on the attic when air sealing.
