Full Editorial Writeup

This is a nearly 30-year-old marine construction business serving the Alabama and Northwest Florida Gulf Coast. The company builds and repairs docks, piers, decks, boathouses, boat lifts, seawalls, and pilings, and also handles dredging, excavation, and commercial marine work. It takes projects from design and permitting all the way through construction, which is meaningful because permitting expertise in coastal waterfront work is a genuine barrier to entry. The customer base skews roughly 80% residential and 20% commercial.

The operating leverage here comes from specialized hard assets and know-how rather than headcount. The sale includes roughly $725,000 in equipment, including two custom aluminum spud barges with cranes and power packs, plus dredging, piling, and excavation gear. The team is lean at three full-time employees including an experienced lead, and the business runs on $1.62M in revenue producing $516K in adjusted SDE, a healthy 32% margin for a construction operation.

What makes it notable is the combination of a durable waterfront market, real permitting and equipment barriers, and a current backlog of about $750K with work scheduled at least two months out. The seller owns the warehouse/storage facility and intends to lease it to the buyer rather than include it in the sale, so the asking price is for the operating business and equipment only. At 4.65x SDE this prices as an equipment-heavy contractor, and the buyer should underwrite it accordingly.

Why we like it

Earnings quality is solid for a contractor at $516K SDE on $1.62M revenue, a 32% margin that reflects the specialized nature of the work and limited competition. The current $750K backlog with jobs scheduled two months out gives immediate revenue continuity, and the lean three-person team keeps overhead low relative to cash flow.
The moat is real for a small business: marine construction requires permitting expertise, specialized barges and dredging equipment, capital, and experienced crews that took nearly 30 years to assemble. Fewer regional competitors offer the full breadth across docks, seawalls, dredging, piling, and commercial work, which lets this operator win more complex and higher-margin jobs.
Market tailwinds favor the geography, as the Alabama and Northwest Florida Gulf Coast has an extensive waterfront base that continually needs new docks, repairs, seawall replacement, and shoreline protection. Storm damage and aging infrastructure create non-optional repair demand that supports steady work even if new-build discretionary projects slow.
The operator advantage is meaningful because the seller has historically done little paid marketing, so a buyer who adds digital advertising, local search, and systematic lead generation can grow revenue without changing the core model. Increasing equipment utilization on the barges and dredging gear plus building recurring inspection and maintenance contracts are clear paths to higher and more stable cash flow.

How to improve it

Launch a structured digital marketing program in the first 90 days, including local SEO, Google Business Profile optimization, and paid search for high-intent terms like dock repair and seawall installation. The business admits it has relied little on paid marketing, so even a modest budget should lift lead flow into the existing backlog machine.
Build a recurring maintenance and inspection program targeting the existing residential base, offering annual dock, lift, and seawall inspections plus priority repair scheduling. This converts one-time project customers into a repeatable revenue stream and smooths the seasonality inherent in coastal construction.
Push the customer mix toward commercial, marina, and HOA work, which the listing flags as underdeveloped at only 20% commercial. These clients place larger, less price-sensitive, and often multi-phase orders that improve project economics and utilization of the specialized barge and dredging equipment.
Increase utilization of the dredging and spud-barge assets, which are expensive to own and idle when not deployed. Marketing dredging as a standalone service to marinas, developers, and municipalities monetizes equipment that is already paid for and included in the sale.
Formalize the estimating, permitting, and project-management workflow into documented systems so the business is less dependent on the owner's institutional knowledge. This protects margins, speeds up bidding, and makes the operation more scalable and eventually more sellable.
Address key-person risk on the experienced lead employee by putting a retention and cross-training plan in place early. With only three full-time staff, losing the lead would be materially disruptive, so lock them in and document their skills.
Negotiate a long-term facility lease with the seller with clear renewal options and a purchase option on the warehouse. Since the real estate is being retained and leased back, securing favorable terms protects continuity and prevents a future rent squeeze.

Diligence notes

Verify the $516K adjusted SDE by reviewing the add-back schedule, tax returns, and bank statements for the last three years. Construction cash flow can swing with a few large projects, so confirm the earnings are recurring and not driven by a single unusually strong 2025.
Independently appraise the $725,000 FF&E, especially the two custom aluminum spud barges, cranes, dredging, and piling equipment, and confirm condition, remaining useful life, and clear title free of liens. Since these assets make up a large share of the asking price, an inflated equipment value would distort the true operating multiple.
Scrutinize the facility lease terms the seller intends to establish, including rent, duration, escalators, and renewal rights, since the warehouse is not included in the sale. Understand whether the proposed rent is at market and how it affects go-forward cash flow versus historical figures.
Confirm the $750K backlog is real, signed, and priced at healthy margins, and review the pipeline and permitting status for scheduled jobs. Also examine customer concentration to ensure no single client or project is carrying the revenue base.
Review the permitting and licensing situation carefully, including any contractor licenses, marine and environmental permits, and whether they transfer to a new owner or must be re-obtained. Permitting expertise is cited as a core barrier to entry, so understanding who holds the credentials is critical.
Assess key-person dependence on both the owner and the experienced lead employee, including who manages estimating, client relationships, and field operations. Confirm the seller's transition and training commitment and whether the lead employee intends to stay post-sale.
