5 Signs Your Dock Needs Immediate Repair

Owning a lakefront property is a dream come true, with endless days of boating, fishing, or simply relaxing by the water. But your dock—the heart of your waterfront experience—takes a beating from constant exposure to water, weather, and wear. At Build SML, we’ve seen countless docks in need of TLC, and catching problems early can save you from costly replacements or safety hazards. Here are five critical signs your dock needs immediate repair, along with tips to keep it in top shape.

1. Wobbly or Unstable Boards

If stepping onto your dock feels like walking on a shaky bridge, it’s a red flag. Loose or wobbly boards often indicate weakened supports, rotting wood, or loose fasteners. This instability can make your dock unsafe for you, your family, or your guests.

What to Check: Walk across your dock and note any areas that feel uneven or shift under your weight. Inspect the decking for loose nails, screws, or boards.

Why It’s Urgent: Unstable boards can lead to trips, falls, or even a collapsed section of the dock, especially under heavy loads like boats or gatherings.

Quick Tip: Tighten loose screws or nails as a temporary fix, but call Build SML for a professional inspection to address underlying structural issues.

2. Rusted or Corroded Hardware

Docks rely on metal hardware like bolts, brackets, and anchors to stay secure. Over time, exposure to water—especially in saltwater or high-humidity areas—can cause rust or corrosion. Rusty hardware weakens the dock’s integrity and can fail unexpectedly.

What to Check: Look for reddish-brown rust on bolts, hinges, or railings. Pay special attention to areas submerged in water, like pilings or anchor points.

Why It’s Urgent: Corroded hardware can snap under pressure, causing parts of the dock to detach or collapse, posing a safety risk and potentially damaging your boat.

Quick Tip: Replace rusted hardware with marine-grade stainless steel or galvanized options, and let Build SML assess whether the damage has spread to other components.

3. Algae or Mold Buildup

Green, slippery algae or black mold spots on your dock aren’t just unsightly—they’re hazardous. Algae thrives in wet environments, making your dock a slip-and-fall risk, while mold can indicate deeper moisture issues in wooden docks.

What to Check: Inspect for slimy patches, green streaks, or dark spots on the decking, especially in shaded areas or where water pools.

Why It’s Urgent: Slippery surfaces increase the risk of injury, and mold can accelerate wood rot, compromising the dock’s structure.

Quick Tip: Clean algae with a pressure washer and eco-friendly cleaner, but if buildup persists, Build SML can recommend durable, low-maintenance decking materials to prevent future issues.

4. Structural Cracks or Splintering Wood

Wooden docks are prone to cracking, splintering, or warping due to constant moisture and UV exposure. These issues weaken the dock and can make it uncomfortable or unsafe to use.

What to Check: Look for visible cracks, splinters, or warped boards, especially on high-traffic areas like steps or edges. For floating docks, check for cracks in the floats or pontoons.

Why It’s Urgent: Cracks can worsen over time, leading to broken boards or complete structural failure, which could result in injuries or costly repairs.

Quick Tip: Sand down minor splinters for temporary relief, but contact Build SML to replace damaged sections with durable materials like composite decking.

5. Floating Dock Instability or Sinking

For floating docks, instability or sinking is a serious issue. This can happen when floats become waterlogged, anchors loosen, or connections between sections weaken.

What to Check: Notice if your floating dock tilts, sinks slightly, or feels uneven when you walk on it. Check for water inside the floats or loose anchor lines.

Why It’s Urgent: A sinking or unstable floating dock can become unusable, damage boats, or create unsafe conditions for swimmers or dock users.

Quick Tip: Avoid using the dock until it’s repaired. Build SML’s team can inspect and replace damaged floats or re-secure anchors to restore stability.

Why Act Now?

Ignoring these warning signs can turn minor dock issues into major expenses—or worse, safety hazards. A well-maintained dock not only enhances your lakefront lifestyle but also protects your property investment. Regular inspections and timely repairs can extend your dock’s lifespan and keep it looking great for years to come.
