Stop Drafts Before They Start: Seal Gaps with Spray Foam

12 September 2025

Custom Insulation Company, Inc. - Spray Foam

As the colder months approach, many homeowners notice a familiar problem—drafts sneaking in through tiny cracks and gaps around the house. Not only do drafts make your home less comfortable, but they also drive up energy bills as your heating system works overtime to compensate. The solution is simple and effective: seal those gaps with spray foam insulation.

At Custom Insulation Company, Inc., we specialize in helping homeowners keep the cold air out and the warm air in. Spray foam is one of the most reliable ways to stop drafts before they start, and here’s why it works so well.

Why Drafts Are a Big Deal

Even the smallest gaps around windows, doors, pipes, and attics can let cold air in and warm air out. Over time, these leaks make your home harder to heat, reduce comfort, and increase energy costs. Traditional insulation can help, but it often leaves gaps that air can still pass through.

How Spray Foam Solves the Problem

Spray foam expands to fill every crack, gap, and crevice. Unlike other types of insulation, it creates an airtight seal that blocks both air and moisture. This makes it incredibly effective for stopping drafts and preventing heat loss in your home.

Benefits of Sealing with Spray Foam

  • Lower Energy Bills: Less heat escapes, so your furnace doesn’t work as hard.
  • Improved Comfort: No more cold spots or chilly breezes in the winter.
  • Moisture Control: Spray foam keeps out unwanted moisture that can lead to mold.
  • Long-Lasting Protection: Once installed, spray foam insulation provides durable results for years to come.

Where to Use Spray Foam

Spray foam is especially effective in attics, basements, crawl spaces, and around windows and doors—common places where drafts are most noticeable. By sealing these areas, you can make your entire home more energy efficient and comfortable.

Seal Out the Cold with Custom Insulation

Don’t wait for drafts to creep in this winter. With spray foam insulation from Custom Insulation Company, Inc., you can protect your home from heat loss, reduce energy costs, and enjoy a warmer, more comfortable living space all season long.
