What’s happening under your home affects how it feels inside.
If you’ve ever walked barefoot across your floor and wondered, why is it still so cold down here?, you’re not imagining things—and the solution may be insulating your crawl space.
At Metro NY Insulation we have been insulating crawl spaces since 2005, and we talk to homeowners across New Jersey and Westchester County every week who are struggling with uncomfortable floors, stubborn humidity, and heating and cooling systems that seem to work overtime. One of the most overlooked causes? A poorly insulated crawl space.
Let’s pull back the curtain on what’s really happening down there—and how proper insulation makes a difference.
Why Crawl Space Insulation Matters More Than You Think
We get it—out of sight, out of mind. But what’s happening under your home directly impacts:
Indoor temperatures
Air quality
Energy efficiency
Moisture and mold control
When your crawl space is exposed to unconditioned air, moisture, or temperature swings, all of that seeps upward into your home. That’s why your floors may feel cold in spring or fall—even when the thermostat looks fine. It’s also why your air might feel damp or musty in the summer.
Signs Your Crawl Space May Need Insulation
Your floors feel cool or clammy, even when the heat or AC is running
You notice high humidity levels indoors during spring or summer
Your energy bills don’t seem to match the mild weather
You’ve seen signs of mold, condensation, or wood rot around the base of your home
The rooms above your crawl space never feel as comfortable as the rest of the house
If any of these sound familiar, you’re not alone—and we can help.
What We Do to Fix It
At Metro NY Insulation, we take a full-service approach to crawl space efficiency. That includes:
Installing insulation in the crawl space walls and rim joists
Sealing air leaks that allow outdoor air and moisture to sneak in
Adding moisture barriers to prevent long-term damage
Choosing the right materials—like spray foam or rigid board—for your unique home
We don’t just throw insulation in and leave. We inspect. We explain. And we make sure the solution matches your climate, home layout, and comfort goals.
Year-Round Benefits
The best part? Crawl space insulation helps in every season:
In spring and summer, it reduces humidity and keeps cool air inside
In fall and winter, it blocks cold air from rising through your floors
All year long, it helps your HVAC system work smarter—not harder
