A bouncy laminate floor is almost always caused by an uneven subfloor, an underlayment that is too spongy, or a lack of proper expansion gaps along the walls. Because laminate is a "floating" floor, it needs a stable, flat foundation to avoid flexing when you step on it.
Inspect the subfloor by lifting the laminate boards in your problem areas. Look for and measure any uneven areas. Use a self-levelling compound for concrete subfloors or plywood sheeting for wooden subfloors. Ensure the subfloor is completely clean, dry and free of debris before reinstalling your laminate planks.
If your laminate floor feels bouncy, it's usually a sign that something's not quite right underneath. It could be a slightly uneven subfloor, the wrong underlay, or not enough space left around the skirting boards during installation.
Laminate flooring needs room to expand and contract due to temperature and humidity changes. If the expansion gap is too small or missing, the laminate will move under pressure, causing a spongy or bouncy sensation. This is a common reason why does my laminate floor feels spongy.
Even a more noticeable bounce can be normal, as bouncy laminate flooring may take weeks or months to feel fully settled and sturdy.
To allow the floor to settle into place, you should wait 24 hours after most laminate flooring installation. However this can vary based on the specific type and brand of laminate and the installation method used. In some cases, manufacturers say that you can walk on the floor immediately.
DIY Fixes for Minor Floor Bounce Issues
Causes of Bouncy Floors in Your Home
Inadequate Support: Insufficient support structures, like poorly installed or shifted posts and beams, can lead to bouncy floors. Weakened Joists: Factors like moisture, wood rot, pest damage, or general wear can weaken wooden floor joists.
Exercise caution to avoid damaging the flooring's surface. Inject Stickit Pro Epoxy: Inject Stickit Pro epoxy into the holes, ensuring it fills the void beneath the laminate. Apply Pressure: Apply weight or pressure to the affected area until the epoxy sets. Clean Up: Remove any excess epoxy from the surface.
The laminate itself is hard, but the compulsory underlayment provides a crucial layer of cushion. This absorbs shock and makes walking on laminate feel softer and less strenuous than walking directly on a fully bonded floor.
When your floor feels spongy when walking, it's not just annoying—it's a warning sign that something underneath has gone wrong. That soft, squishy sensation means the structural layers supporting your feet are compromised, usually by water damage, failing joists, or installation mistakes.
Some Common Mistakes When Laying Laminate Flooring
Laminate floors will always have a slight bouncy feel to them because it's a floating floor with foam underlay in between. If it's really bouncy then they might have used a carpet underlay which is not what you should be doing or you got an uneven sub floor.
Bouncy floors are characterized by noticeable flexing, bouncing, or sagging when walked on. If your floors feel spongy or move up and down when you step on them, you likely have bouncy floors. This issue is often most prominent on the upper levels of homes with a crawl space beneath them.
While vinegar is a popular DIY cleaning solution, it's not recommended for laminate floors. Its acidic nature can dull the laminate's finish over time. Instead, opt for a pH-neutral cleaner specifically designed for laminate flooring to ensure it remains vibrant and undamaged.
Hollow Spots and Flex Zones
If certain areas feel softer or slightly springy, that's a hollow zone beneath the laminate. Why this happens: Underlayment too thick. Gaps between subfloor panels.
Laminate flooring needs time to settle into the place you install it. Let the laminate planks sit in the room for at least 48 hours before fitting them so they don't expand or contract after installation, making gaps in the flooring or buckling.
Minor warping can sometimes be flattened, but severe warping usually requires replacement of affected planks. 2. How do I stop laminate flooring from buckling? Ensure a 10mm expansion gap around the room, control humidity, and avoid excessive moisture exposure.
Expected lifespan of laminate floors
On average, laminate flooring can last 15 to 25 years with proper care and maintenance.
If you've noticed the floors above your crawl space having an extra bounce to them as you walk, it could be time to schedule a professional inspection. ⚠️ Bouncy floors are oftentimes a warning sign of a more serious structural issue like failing floor joists.
The minimum code standard is L/360, where L= length of the span in inches. That means with a minimum code floor, your joist would be allowed to deflect up to 1.2" under max load. Even under light loads, that is going to feel springy.
Floors start bouncing because they're uneven, don't have gaps, are trapping moisture or weren't laid down properly.
Step 2: Checking the Spaces Around the Floor
Laminate floor requires an expansion gaps of about ~10mm, because the floor can expand and contract due to temperature and humidity changes. So, I removed the wall skirting boards in 2 sides of the room, in order to check the spaces around the laminate floor.
This can be due to excessive moisture, humidity, or pest infestations, leading to rot, mold, or damage to the wooden structures that support your home. The result of this damage is a loss in the stability of your floors, thus causing them to feel bouncy or springy.
