Southern California Attic and Building Air Sealing

Air sealing helps control your home’s temperature, moisture levels, and energy costs by preventing unwanted air movement between your living space and the outdoors.

We’re experts in finding and sealing the air leaks in your home.

Our air sealing services can help:

  • Lower energy bills: Air leaks force your heating and cooling systems to work harder, increasing your utility costs.
  • Improve comfort: Air leaks can make rooms too hot or too cold and create uncomfortable drafts.
  • Prevent moisture problems: Air leaks can bring moisture into your walls and attic, leading to mold growth and structural damage.
  • Improve air quality: Air sealing helps keep outdoor pollutants, allergens, and dust from entering your home.

Before we recommend air sealing work, we perform a thorough evaluation as part of our free in-person estimate:

We Check All Common Air Leak Points

  • We inspect attic penetrations like light fixtures and duct openings.
  • We examine walls for gaps around electrical outlets and switches.
  • We look at window and door frames for failed seals.
  • We check where pipes and wires enter your home.
  • We use diagnostic tools to find otherwise hidden air leaks.

We Plan The Work Carefully

  • We select the right sealing materials for each type of leak.
  • We ensure all work meets building codes.
  • We protect your home’s structure and safety.
  • We can help with any required permits.

During your free estimate we take time to understand your home in detail so that we can recommend the right air sealing approach, estimate how long the job will take, and equip our crew correctly for a job done right.

We help guide you through all these options and more.

We want you to get the air sealing that works for your needs, and we aren’t incentivized to sell you services that don’t make sense for your home or budget.
