Your deck should be a summer escape—not a structural hazard.
But over time, even the best-built decks can start to show signs of wear. At Tru-Pro Construction, we’ve repaired enough splintered steps and sagging boards to know the red flags. Here’s a breakdown of the most common deck issues we see in Martinsville and how to fix them before they become safety concerns (or budget nightmares).
1. Wobbly Railings
The problem: Loose or shaky railings aren’t just annoying—they're dangerous.The fix: In most cases, this means the fasteners have loosened or rotted out. Tighten all hardware or replace with longer screws. If the post is rotted, it may need to be replaced or re-anchored to the frame.
2. Warped or Cracked Boards
The problem: Sun, rain, and time can warp wood, causing boards to curl, crack, or split.The fix: Small cracks can be filled with a flexible epoxy filler, but severely warped boards should be removed and replaced. Use pressure-treated or composite decking to extend longevity.
3. Rotten Posts or Joists
The problem: Rot usually begins at the base where moisture builds up. Left unchecked, it compromises the deck’s entire structure.The fix: Inspect support posts and joists regularly. Replace any rotted lumber, and install metal post bases to elevate wood above moisture-prone ground.
4. Popped Nails or Screws
The problem: Fasteners can work their way loose over time, making boards unsafe and uneven.The fix: Remove the popped fasteners and replace them with corrosion-resistant deck screws, which grip tighter and last longer than nails.
5. Fading and Peeling Finish
The problem: UV rays and moisture will strip stain and paint, leaving your deck vulnerable to the elements.The fix: Strip old finishes, sand rough spots, and apply a high-quality sealant or stain designed for UV and water protection. Reapply every 2–3 years.
6. Loose Ledger Board
The problem: If your deck is attached to your home, the ledger board is what anchors it to the structure. If it pulls away, it’s a serious safety issue.The fix: Re-secure it using lag bolts or structural screws. Never rely on nails alone. Add flashing to keep water out and prevent rot.
Pro Tip: Routine maintenance saves money.
Don’t wait for something to break. A professional inspection can catch early signs of damage and extend the life of your deck for years.
