installing attic ventilation

An efficient home can save you from high utility bills and create a more comfortable environment. In addition to using insulation, attic air sealing is a process to seal every possible opening or gap in your home’s attic.

Opting for attic sealing services may provide your home with numerous benefits. However, to get the best results for your air sealing, you should hire trained attic sealing professionals.

What Is Air Sealing an Attic?

Sealing an attic, also referred to as “air sealing,” entails finding every gap, potential opening, faulty seam, and cavity in your attic. Closing off these troublesome spots with a sealant provides the ultimate protection from drafts, pests, ice dams, and more.

The Need for Sealing an Attic

Is air-sealing the attic worth it? There are plenty of advantages to sealing attics, like improved comfort levels and better energy efficiency for your HVAC system. While these benefits are great, they’re not a necessity for homes. However, you need a properly sealed attic to ensure healthy airflow throughout your home.

Adequate airflow is important for keeping harmful mold growth from remaining trapped inside your home. If you do not seal your attic, it can allow air and moisture to enter the home. When this moisture or air accumulates, it can create ice dams in your roof and uneven temperatures throughout the home.

Cost to Air Seal an Attic

The good news is that attic air sealing costs aren’t astronomical. While some DIY the project to save on air sealing attic costs, having professionals complete the sealing process guarantees a job well done and reduces attic sealing costs in the future.

Generally, attic air sealing costs between $1,000 to $3,000. However, this cost depends on the square footage of your attic, the number of areas that require sealing, and the costs of materials you and your qualified technician choose.

Process of Attic Sealing

You can expect a few key steps when sealing an attic. First, you schedule an inspection for an attic expert to take note of any gaps, weak seals, and problem areas. Experts find these air leakage spots using various detectors by exploring hard-to-reach spaces in your attic or crawl space.

Then, they’ll work to fill those problem areas with the most suitable material, so air can no longer flow through the area. Some materials used to fill these gaps include closed-cell spray foams, caulks, and other weather-resistant sealants.

This way, your home stays protected during the winter from cold drafts and in the summer from warm, humid air with the quality guarantee of a professional attic sealing company.

The Benefits of Attic Sealing

Maybe you’re still wondering if air-sealing the attic is worth it. If so, consider this comprehensive list of benefits to sealing your attic. One of the biggest perks of attic sealing is better indoor air quality. When you can control what goes in and out of your home more closely with sealing, fewer particles like allergens enter the air.

Another advantage to attic sealing is even heating and cooling throughout your home. The days are long gone when one room is freezing and others are warm while running your HVAC unit. Instead, attic sealing prevents leaks which help to create the optimal conditions for your HVAC unit. In addition to more consistent heating and cooling, you can save on utility bills and promote overall efficiency across your home.

A final perk to attic sealing includes protection from excess humidity. When your home has gaps and leaks, you put your attic at risk of trapping warm, humid air. If left unattended, this excess humidity can create the perfect environment for mold growth and pest infestation. Fortunately, attic sealing protects your home from both of these problems.

Does the Attic Need To Be Airtight?

Your attic does not need to be 100% airtight. Attics often feature their own types of ventilation and sealants. Ventilation allows the attic temperature to cool off during hot months. However, sealing works to fill the gaps and seams that do not help with your energy efficiency and airflow. Areas professionals seal include weak spots that allow pests in, drafty areas, and sealing the attic hatch of your attic to protect your home from drafts.

Why Do People Seal Attics?

People seal their attics for big savings on energy efficiency. Attic sealing prevents any major leaks from affecting the temperatures inside your home. More often than not, homeowners combine attic sealing with insulation to lower utility costs and prevent ice dam formations which can lead to mold and mildew growth.

What Can I Use to Air-seal My Attic?

Spray foam insulation, caulk, and different sealants all work to treat attic leaks. If the leaks and gaps in your attic are significant, you may need to pair insulation with a high-grade sealant. For these reasons, it’s best to discuss which works best for your unique attic layout and needs with a professional before completing the job.
