Is Air Sealing the Attic Worth It?

Home improvement isn’t always affordable, which is why many homeowners delay some project until necessary. But, one project you should consider is air sealing your attic. Below, we’ll discuss everything you need to know about this process, including the savings, to help you determine if it’s worth the investment.

Air Sealing an Attic: What the Project Involves

Air sealing an attic is a labor-intensive process that involves closing holes in your attic’s walls, ceilings, and floors. You’ll need various tools and safety equipment to get started, including unfaced fiberglass insulation, garbage bags, a roll of aluminum flashing, a caulk gun, and a can of expanding spray foam insulation.

Completing this project yourself is possible, but it requires a lot of patience, a willingness to learn, and some trial and error.

Instead, we recommend recruiting a professional to do the job. A professional can work safely in small spaces with poor ventilation. And, they can finish air sealing your attic efficiently so that your household can resume daily routines.

Not every attic requires air sealing. Here are some telltale signs that indicate yours does:

  • Drafty rooms
  • Abnormally high cooling or heating bills
  • Icy dams or dry indoor air during the winter
  • Dust (especially in rooms located directly underneath your attic)

If you notice one or more of the following signs, you might have a few air leaks on your hands that require sealing.

Some homeowners may flinch at the initial cost of air sealing services. However, these services are well worth the money in the long run.

According to the EPA, homeowners lose between 25 and 30% of their cooling and heating energy via attic air leaks.

Depending on the size of your home, you can save up to $200 per year on your heating and cooling costs when you address air leaks. If you spend $1,000 on attic air sealing services, you’ll earn a 20% ROI per year.

Other Benefits of Air Sealing an Attic

Besides the direct savings on your heating and cooling costs, attic air sealing provides various other financial, health, and safety benefits. Check them out below:

Improved Home Comfort

After a long day at work, nothing feels better than returning to a house with a pleasant temperature. But, if you have air leaks in your attic, you’ll likely be sitting in uncomfortable conditions.

A porous attic will allow more heat to enter your living space during the warmer months. Once winter rolls around, these holes can result in substantial heat loss.

Depending on the time of year, you may find yourself needing to crank up the A.C. or heater to remain comfortable. Getting into habits like these can add up. For example, some homeowners in certain U.S. regions allocate 70% of their electric bill to air conditioning alone during the summer months.

When you invest in air sealing services, you can close up any glaring holes and relax without having to adjust your A.C. or heater every day.

Plus, air sealing your attic will also help all the rooms in your home remain at a consistent temperature. As you’re walking from the living room to your bedroom, you won’t feel like you’re walking from the Sahara and into the Arctic Tundra.

Less Cleaning & Better Air Quality

Is there nothing you hate more than dust bunnies? If you have gaps in your attic, you may be all too familiar with them.

These holes can invite unwanted pollen, dirt, and other allergens and contaminants into your home. This air quality problem is especially severe in the summer, as dust rises with the warm air that enters your upstairs space.

You can improve the air quality of your home by sealing gaps in your attics. Taking this initiative will prevent you from having to pull out the feather duster every day. It also acts as a great way to improve your family members’ allergy symptoms, especially for those with asthma or other respiratory health problems.

Pest Prevention

Uninvited pests are relentless — they’ll take advantage of any available opportunity to invade your home. Give them one less entry point by sealing up leaks in your attic.

When you close up larger holes, you can keep out large rodents like rats, mice, squirrels, and raccoons.

While most homeowners address larger holes first, you shouldn’t neglect the smaller ones. Patching up small gaps can keep smaller (but still dangerous) pests like cockroaches and termites at bay.

All types of pest prevention are essential, as these intruders can chew through wires and pick away at your home’s support beams.

And trust us, your wallet will thank you. For example, did you know that homeowners with termite problems pay around $3,000 on average to repair the resulting damage? When you invest in attic air sealing services, you can keep peace in your home (and your wallet shut).

Reduced Moisture & Mold

After several heavy downpours, a small hole in your roof can lead to significant water damage in your attic. This added moisture will likely lead to unsightly mold growth, which can:

  • Leave foul odors behind
  • Damage your home’s structural integrity
  • Ruin your furniture or other precious belongings
  • Cause health issues

And mold remediation isn’t cheap. It can set you back as much as $6,000, depending on the size and severity of the affected area.

Combining Attic Air Sealing & Insulation

When discussing attic air sealing, we can’t neglect insulation. Some homeowners may view these two services as one and the same, but they are very different. Both can contribute to the longevity of your home but in varying ways.

Attic air sealing involves blocking air from flowing through gaps and holes in your attic. Insulation involves preventing heat from moving through the attic ceiling, floor, and walls.

Many homeowners choose to get attic air sealing and insulation services simultaneously. If you have a recently built home, you might not require insulation services. An experienced HVAC technician can help you decide what services make sense for your home
