Cracks or cap damage
Hairline cracks in the cap are common. A crack that widens, runs into the panels or bleeds rust is the one to show a contractor. Take a photo with a ruler or tape beside it.

Leaning, leaking or sinking? Find your permit office first.

Each page draws on Mobile Bay permit offices, local ordinances, public bids, tide gauges and storm reports.
What you see at the wall
Match the sign
to the repair.
A crack, a lean, a sinkhole and storm damage each point to a different job. Pick the sign that looks like your wall.
Sinkholes or settling soil
A hole or soft patch in the yard behind the bulkhead means sand is washing out through the wall. Rope it off, keep mowers away and note if it grows after a high tide or a hard rain.
Leaning or bulging wall
If the top of the wall tips toward the water, the anchors or the soil at the base have let go. Set a stake and measure the lean every couple of weeks so you know if it is still moving.
Damage after a storm
After a storm, line up today's wall against older photos. Check for a shifted cap, fresh gaps, lost backfill and loose pier connections, and stay back from the edge until someone has looked.

Who does bulkhead repair around Mobile Bay?
A qualified marine contractor, often building from an engineer's drawings. State law sets a $10,000 line for paid residential repair, above which a builder needs a Home Builders Licensure Board license. Home Builders Licensure Board State general contractor licensing begins at $100,000. General Contractors Board Check credentials with the contractor check guide first.
What permits does a bulkhead need here?
Expect three or four approvals. The Corps of Engineers, ADEM and State Lands review most new or replacement walls, and a city or county office reviews the build. For bank stabilization the Corps often relies on Nationwide Permit 13. Corps Nationwide Permit 13 State Lands allows a replacement wall as much as 2 feet waterward of mean high tide. State Lands rule 220-4-.09 Read the permit guide.
How is Mobile Bay different from the Gulf beaches?
Two counties, Mobile and Baldwin, share the shore, and each city sets its own rules. The bay is a broad, shallow estuary about 10 feet deep on average, 11 miles across and 31 miles long. NOAA About Mobile Bay Dauphin Island is the exception: its ordinance bans seawalls and riprap on the Gulf-facing shore. Dauphin Island Ordinance 105 See the west end guide.
Why do Eastern Shore piers matter for bulkhead owners?
Shallow water along the Eastern Shore means piers often run far out to reach a boat. After Hurricane Nate, Baldwin County had just under 200 damaged piers. NWS Mobile Nate report A pier and a bulkhead often share one permit path, so read the dock and boat lift page.
What did Katrina do to the Mobile Bay shore?
At the Mobile State Docks gauge, Katrina reached 11.45 feet on August 29, 2005, just under the 1916 record of 11.60. NWS Mobile Katrina report Surge reached 12 to 14 feet in Bayou La Batre and flooded downtown Mobile. NWS Mobile Katrina impacts Have any wall that took surge checked by a professional. See the storm guide.
What does a bulkhead cost near Mobile?
National guides give $100 to $800 for each linear foot of new wall, and material and site drive the range. [7] Repair typically runs $100 to $250 per foot. [7] Read the cost guide for the detail.
Can foam injection fix a sinking yard behind my wall?
Sometimes. Foam can fill voids behind a sound wall, but it does not fix a leaning wall or a failed anchor. Ask what is letting the soil escape first. Repair of an existing, permitted wall may fit a Corps maintenance permit. Corps Nationwide Permit 3 Read the foam injection page.
What if the wall fails during a storm season?
Photograph it, keep people away and call the permit offices fast. When life or property is at risk, the Corps runs an emergency permit, and ADEM can approve emergency action for up to 120 days. Corps emergency permit ALGP-15 ADEM rule 335-8-1-.07 See the storm guide.
