Why Is My Deck Bouncy?
A bouncy or spongy deck usually means the structure underneath is failing. We see this often in older homes in Bluff Park and Greystone where decks were built years ago.

Water Rot
This is the most common cause. Water gets trapped between the deck boards and the joists. Over time, the top edge of the joist turns soft, meaning the screws can no longer hold the boards tight.

Over-Spanned Joists
If the original builder used joists that were too small or spaced too far apart, the wood will eventually sag under its own weight. This creates a "dip" in the floor that collects water and worsens the problem.

Rusted Hangers
The metal brackets (joist hangers) that hold the wood in place can rust out, especially if they weren't rated for treated lumber. If a hanger fails, the joist drops, and the deck floor drops with it.
Common Questions About Joist Repair
How much does it cost to repair deck joists?
It is much cheaper than building a new deck. Structural repairs typically start around $750. The final cost depends on the number of joists that need attention and how much of the deck surface we need to remove to access the frame.
Can you fix the joists without removing the deck boards?
Rarely. To properly bolt a new joist in place and ensure it is level, we almost always need to remove the deck boards above the damaged area. If your deck boards are screwed down, this is easy. If they are nailed, we may have to replace the boards we pull up.
How do I know if my joists are rotten?
Look at the screws or nails on your deck floor. If they are popping up or sinking deep into the wood, the joist underneath is likely soft. You might also notice that the railing feels loose because the bolts underneath have nothing solid to grab onto.
Is my deck safe to walk on?
If the bounce is severe, or you hear cracking sounds when you step, stay off the deck because it’s probably time to build a new deck. A failed joist can lead to a sudden collapse of that section. Call us for a safety inspection immediately.
