Coastal Marine Group

What Coastal Marine Group does

Coastal Marine Group (legally Coastal Marine 18, LLC) is a private marine construction contractor headquartered at 424 SE 47th Terrace A in Cape Coral, Florida. The company engineers, permits, and builds custom docks, seawalls, boat lifts, and dredging projects for residential waterfront property owners across the Southwest Florida shoreline, including Cape Coral, Fort Myers, Naples, Sanibel, Captiva, Port Charlotte, Punta Gorda, Venice, Englewood, and Bonita Springs. Its technical approach is engineering-driven rather than template-based: each project is evaluated for soil conditions, water depth, tidal patterns, and vessel requirements before a custom quote is produced, with construction methods tailored to saltwater exposure, marine growth, storm surge, and corrosion. Differentiated service lines include full-depth piling wrapping below the waterline, hurricane-rated Tiki Huts, marine electrical and plumbing, shoreline restoration, and a Boat Lift Maintenance Program, plus a transactional e-commerce catalog of dock accessories and marine lighting (Broward Casting, Benfive).

The business model is professional services with a custom-quote pricing structure — projects are bid on scope, materials, and engineering requirements rather than published price tiers, and revenue is generated through direct field sales, a physical showroom, and phone- and website-driven quote requests. The customer base is exclusively residential SMB (waterfront homeowners), with no enterprise or commercial accounts disclosed, and revenue diversification is achieved through recurring maintenance and repair services (pile scraping, storm damage repair, lift maintenance) layered on the custom construction backlog. The company is independently owned with no parent company, no outside capital, and no public listing, and operates with a small leadership surface (Bob Cantu identified as a team member) and a 23+ five-star Google review footprint concentrated in Cape Coral neighborhoods. Distribution is regional and direct, supported by a marketing/referral partnership with Old Florida Roofing and a related-entity affiliation with CMG Docks.
