Air Sealing

If you knew that change was slipping out of your wallet every time you used it, you wouldn’t just let it happen. And if you knew some of the conditioned air in your home was escaping and making your energy bills go up, you would stop it. The idea is the same: if we can keep from wasting money, we will. That’s why it’s important to seal air leaks in your home.

What are air leaks?

Houses are meant to be as airtight as possible, to keep the inside in and the outside out, but that simply isn’t always the case, especially for homes that have been around for a while. Air leaks are small leaks that can form at pretty much any material seam in your home and allow cool air out of your house. Even the smallest leak could cost you big because air molecules want to be the same temperature as the other air around them. This means that warm air will rush into your home and cool air will be pulled out.

Common Air Leak Locations

Technically, air leaks can happen almost anywhere in your house, but there are a few places where they’re more common:

  • Windows and doors
  • Electrical fixtures (lights, outlets, etc.)
  • In and around the fireplace
  • Ducts and Vents
  • Wall material seams (especially corners)
  • Attic access
  • Plumbing fixtures
  • Garage walls

How to Detect Air Leaks

With so many places for air leaks to hide, homeowners often ask, “How can I tell if my house has air leaks?” If you’ve noticed a steady increase in energy bills or simply want to make sure your home is sealed, you can conduct a visual inspection to find leaks. On the exterior of your home, look for cracks at corners, where the foundation meets the siding, at exterior faucets and around the chimney. Inside your home, check for cracks in the caulking around pretty much any seam. This includes vents, outlets, light fixtures and even the seam between your walls and the floor.

One of the biggest hot spots for air leaks is windows and doors. Inspect them for cracks both inside and outside of the frame, and check that the weather-stripping is intact.

What Our Customers Have To Say

Good Rebates

This is a review for a complete HVAC system replacement from Big Mountain. I started at the SMUD website looking for the best rebate program and found a list of contractors there. I vetted out companies that had a lower number of completed jobs per the SMUD rebate program data.

Very Professional

Had my A/C go out yesterday, called Big Mountain today and they had a serviceman in my area of Lincoln, he was here within a half hour and fix my unit in a very professional manner, and the cost was reasonable. I was very impressed with the company and the serviceman.

I had a appointment with them between 1-3 and one of their staff members called me and kept me updated when they will arrive which was nice. Steve arrived on time and was really nice for explaining what could the cause be. My ac fan was working but cool air wasn’t coming out.
