Why Do My Floors Feel Bouncy?

Imagine this: You’re meandering through your cozy living room, a warm cup of tea in your hands, when suddenly you feel an unexpected bounce beneath your feet. It’s an unusual feeling, a springiness in your floor. While easy to dismiss as a mere quirk of your home, it might be a warning sign of an unseen issue hiding within your home’s crawl space.

What are Bouncy Floors?

Bouncy floors occur when there’s a subtle give or bounce as you walk across them. Though it may initially seem inconsequential, or even funny, it can actually indicate an underlying structural issue in your home relating to your crawl space.

Why Bouncy Floors are a Problem

Bouncy floors are not just about discomfort or annoyance; they are a telltale sign of potential structural issues in your home. These can include deteriorating floor joists, weakening support beams, or moisture-related damage. If ignored, these problems could escalate, leading to even more expensive repairs and potential safety risks.

What Should I be Looking for in My Home?

Apart from the noticeable bounce as you walk across, you may also observe additional signs such as squeaking sounds, visible sagging, or gaps between the floor and baseboards. Cracks in your drywall or doors and windows becoming hard to open and close can also hint towards the underlying issues.

What Causes Bouncy Floors in My Home?

While various factors can contribute to bouncy floors, a prevalent cause is a compromised crawl space beneath your home. These can include:

  • Over-Spanned Joists: If the joists supporting the floor above your crawl space are placed too far apart or excessively long for their depth, they can become over spanned. This incorrect spacing can make the joists bounce or flex excessively.
  • Inadequate Support: If floor supports like posts or beams are not correctly installed or have shifted, they can quickly fail to provide the necessary support, resulting in bouncy floors.
  • Weakened Joists: Wooden floor joists can weaken over time due to excessive moisture, wood rot, pest damage, or general wear and tear.
