Crawlspace Insulation Cools Your Home

Still Hot Inside? It Could Be Coming From Below.

When we talk about staying cool in summer, most people think of their attic or maybe their windows. But there’s one area that often gets ignored — and it might be the one silently heating up your whole house.

That Space Under Your Feet? It Matters. A Lot.

If your home has a crawl space, there’s a good chance it’s letting in hot, humid air and pushing your air conditioner to the limit. And if your floors feel warm, sticky, or uneven in temperature, your crawl space could be to blame.

At Comfort 1st Insulation, we help homeowners get comfort and efficiency from the ground up — with proper crawl space insulation and sealing.

Why Crawl Space Insulation Matters In Summer

You might think crawl space insulation is just for winter, but the truth is: it’s just as important in the heat.

Here’s what’s really happening:

  • 🌡️ Hot, damp air from outside flows into the crawl space, where it gets trapped.
  •  
  • 🥵 That air pushes up into your floors and living space, making rooms feel warmer and stuffier, especially at night.
  •  
  • 💧 It also raises indoor humidity levels, which can make your AC feel ineffective and cause wood floors to expand, warp, or creak.
  •  
  • 🐶 Pets may sprawl on the floor just trying to find relief, and you might notice you’re constantly adjusting the thermostat — and still not feeling quite right.
