Seawall and bulkhead inspection

What a useful seawall or bulkhead inspection looks at above and below the waterline, who is qualified to do it, what the report should give you, and when to schedule one.

The short answer

A useful inspection looks at the whole wall system — cap, face, joints, anchors, toe and the soil behind — and gives you a written record of what was found, what it likely means, and what should happen next. Marine contractors inspect walls routinely; for structural questions, a licensed professional engineer can give an independent opinion. Schedule one after a significant storm, when you see soil loss or movement, and before buying a waterfront property.

What a proper inspection looks at

Above the waterline

  • Alignment. Is the wall straight and plumb, or leaning or bowing? Good inspectors measure this so future visits have a number to compare.
  • Cap. Cracks, spalling, separation from the wall, rust staining.
  • Wall face. Cracked or spalled panels, split or corroded sheets, rot or borer damage in timber.
  • Joints. Open seams, missing filter fabric, signs of soil washing through.
  • Anchors. Visible tie-rod ends and hardware, signs of anchor movement in the yard.
  • Drainage. Weep holes clear or blocked; standing water behind the wall.
  • The yard. Voids, sinkholes, soft spots, settling pavers or slabs, cracks running parallel to the wall.
  • Neighbors. How the wall ties into the walls on either side, and whether either is failing.

At and below the waterline

The toe is where many walls fail and where an above-water look tells you least. Depending on the wall and the water depth, the inspector may check at low tide, probe the bottom, or dive. Ask how the toe will be assessed and whether that is included.

Who should do it

Marine contractors inspect walls as part of quoting repairs. They see many walls and usually know local conditions well. The limitation is obvious: they may also be the one selling the fix.

Licensed professional engineers with coastal or structural experience can give an independent opinion and design a repair. Engineers are licensed by each state; NCEES lists every state licensing board, where you can confirm a license.[2] Their fee is usually higher, and it is often money well spent on a large or disputed job.

Home inspectors may note visible problems during a property purchase but generally are not qualified to assess a marine structure. Treat a home inspection note as a reason to get a specialist look, not as the specialist look.

What it costs. One national cost guide lists $200–$600 per inspection visit, depending on whether diving is included.[1]

What the report should give you

  • Date, tide conditions and who inspected
  • The length and type of wall inspected, and what could not be inspected
  • Photos tied to locations along the wall
  • Measurements: lean, crack widths, void depths
  • The likely cause of each problem, stated as clearly as the evidence allows
  • Urgency: what needs attention now, soon, or can be monitored
  • Options for repair, and when replacement should be considered
  • Whether an engineer’s design or permits are likely to be needed

When to schedule one

  • After a hurricane, tropical storm or unusual high-water event
  • When you notice soil loss, new cracks or movement
  • Before buying a waterfront property, and before closing if the wall is in question
  • Before a major project near the wall, such as a pool, addition or new dock
  • Periodically, even with no visible problems, because the toe and anchors fail out of sight

After the inspection

If the wall is sound, file the report and use it as a baseline. If it needs work, use the findings to get comparable quotes — every bidder should be addressing the same diagnosis. Our repair guide explains the common methods, and the cost guide covers how to compare proposals.

Questions owners ask

How much does a seawall inspection cost?

One national cost guide lists $200–$600 per visit, depending on whether diving is included, and $2,000–$3,000 for structural engineering design plans if repairs need them. Prices vary with wall length and whether an engineer writes the report, so ask for the fee and a written scope before you book.

Is a free inspection from a contractor worth having?

It can be, as long as you understand that the person inspecting may also be quoting the repair. For a large decision, or when two contractors disagree, an independent engineer's opinion is worth paying for.

Can someone assess my wall from photos?

Photos help a contractor decide whether a visit is urgent and what to bring. They cannot show the toe, the anchors or what is happening behind the wall, so they are not a substitute for an on-site inspection.
