You may have heard this term when talking about your floor. A subfloor is the floor beneath your floor. It’s the foundational support that keeps your floor level and stable. Its importance cannot be overstated. While your main floor may be concerned about looks, your subfloor is what gives your home stability. It’s what allows you to only worry about cosmetics on the top floor and save money.

So let’s explore the subfloor a little more.

What’s it Made of?

A subfloor can be made of various materials. The subfloor is the bottom most layer that is attached to the joists. It’s usually made out of plywood or OSB. Maybe concrete if you’re in the bottom floor.

What does it do?

A subfloor provides full support for your entire home. They attach to the joists and hoist up several layers of flooring above it. All homes have subfloors.

What are Joists?

Joists are not necessarily the floor, but they’re the layout that keep the house structured. It’s the engineering that keeps it all together.

How to Check Your Subfloor

The only way to check on your subfloor is by removing your top layer. That means that your subfloor has to be very sturdy and last a long time. Long enough that you can wait until your top layer of flooring needs to be replaced.

Common signs that your subfloor might be having problems include:

  • Squeaky floors
  • Odors. Indicate mold or water damage.
  • Uneven spots on your floor
  • A bouncy floor
