Home Air Sealing

In terms of home energy efficiency, air sealing is just as important as insulation! Air leaks can greatly reduce the effectiveness of your insulation. If you’re thinking of insulating your home, don’t overlook air sealing (and a professional insulation contractor will make sure you don’t!).

If you live in the Frederick and Damascus, Maryland area, Comfortable Home Energy Audits is your one-stop solution for home energy efficiency. In addition to completing an energy audit, we can seal any air leaks.

Types of Air Sealing

Just like insulating your home, you have more than one option when it comes to sealing air leaks. We can perform attic sealing and whole house sealing, both of which are beneficial and can maximize your energy savings.

Attic Air Sealing

Do you need to insulate your attic? If so, you need to seal air leaks in your attic as well – attic insulation and attic air sealing usually go hand in hand. A properly air sealed attic with a radiant barrier installed is an attic that is truly energy efficient.

When it comes to air leaking out of your house, the attic is one of the biggest culprits. Attics that aren’t air sealed (and insulated) are costing you a lot of money. Air leakage sites can be hard to detect, but that’s where professional auditors come in. We can help you detect leaks in your attic – and we’ll seal them for you!

Note: if your attic is finished, sealing behind kneewalls is important. There are open cavities in the floor framing under the side walls or kneewalls, and these spaces need to be sealed in order to effectively stop air infiltration.

Whole House Air Sealing

Whole house sealing, like the name suggests, goes beyond the attic and is an excellent solution for reducing energy costs. Whole house sealing involves tools such as the smoke pencil (for detecting drafts), thermal imaging camera and blower door to find air leakage sites in your home and seal them.

Where is air leaking into and escaping out of your home? Common sites for air leakage that should be sealed include:

  • Around windows and doors
  • Cracks and crevices in exterior walls
  • Duct vents
  • Crawlspaces
  • Attic hatch
  • Recessed lights
  • Around fireplaces and flues

Note: a little trick you can use on your own to see if your home is as airtight as it should be involves just a single sheet of paper. Shut your window or door on this piece of paper. If the paper doesn’t tear when you pull it out, there’s a problem!

Benefits of Air Sealing

Air infiltration doesn’t only minimize your home’s energy efficiency and cause you to see higher energy bills, but it can lead to:

  • Moisture problems
  • Excess dust
  • Wood rot (particularly in the attic)
  • Entry of pollutants
  • Insect problems
  • Less comfortable environment (in terms of temperature and outside noises)

These host of problems aren't something you want to deal with – and avoiding them is simple with the right air sealing services! Contact Comfortable Home Energy Audits today!
